Patent DE-3006691-A1 (DE)
Inventor: VOIGT SIEGFRIED DIPL ING
IPC: B02C11/00
Filed: 1980-02-22
Abstract: The bulk material flows through the through-flow hopper (17) onto a vibrating separating plate (1) through which air flows. On this separating plate (1), the particles of lower specific weight float upwards, and in the process lose contact with the transporting separating plate and move to the lower plate edge to leave the stone separator via the lightweight part discharge (4). By contrast, the particles of higher specific weight, that is to say the stones, which still have sufficient contact with the separating plate (1), move to the upper plate edge and leave the stone separator through the heavy part discharge (3). If, however, an interruption of the continuous bulk material feed occurs, the through-flow hopper (17) is emptied so that it is pulled upwards somewhat by the spring (13) via the cable pull (15). In the process the spring (13) moves the angle lever (11), so that the blocking strip (10) is lowered. No more bulk material can thus leave the stone separator through the discharge (3). Lightweight bulk material is therefore also not undesirably lost, as was previously the case when the bulk material feed was interrupted and under the unfavourable conditions occurring as the separator plate was emptying. <IMAGE>

Title: Electric razor with touch-control switch - automatically stopping and starting drive motor as razor is put down or picked up
Inventor: EBNER ALBERT DIPL ING
IPC: B26B19/38
Filed: 1980-06-12
Abstract: The razor has the drive motor switched ON and OFF via a touch-control switch incorporated in the outside of the razor casing, with at least two contact zones in the parts of the casing which are gripped by the user. Pref. the front and back of the razor casing incorporate large surface area contact zones with the switch inserted in the supply circuit for the drive motor causing it to be started or stopped as the razor is picked up or put down. Two additional contact zones are provided in the two side faces of the razor casing and are coupled electrically to the two former contact zones, so that the switch for the motor is similarly operated when the razor is held differently for trimming longer hair. All the contact zones can be provided as metal inserts incorporated in the casing. The switch prevents unnecessary energy wastage, e.g. for a battery-operated razor.
Patent DE-3025644-A1 (DE)
Title: Electronic timer circuit - has series resistor operational amplifiers with offset compensation schmitt trigger and triac
Inventor: HARTMANN HANS-HEINRICH DIPL IN
IPC: G07C3/04
Filed: 1980-07-07
Abstract: The circuit has a very low resistance in series with the load. The voltage across this resistance, produced when current flows through the load, after amplification and rectification switches a triac via a schmitt trigger to energise an electric timer. The wire wound resistor (RM) which is in series with the load (RL) is of the order of 5 to 10 mohms. The voltage developed across it is amplified by an operational amplifier circuit with offset compensation (1) and rectified (2). When it exceeds a threshold value it operates a Schmitt trigger (3) which turns on a triac (4). This energises an electric timer (M).
Patent DE-3027777-A1 (DE)
Title: Proximity switch for gas burner - switches gas on and off as necessary as user's hand etc. alters capacity of oscillator circuit
Inventor: OBERMEIER FRIEDRICH
IPC: F23N1/00
Filed: 1980-07-23
Abstract: The gas burner e.g. Bunsen burner has an attached housing into which the gas feed pipe is connected and contains an on/off switch, condition indicators and a capacitive proximity switch. The activating element for the switch is on the upper side so that the hand of a person using the burner approaches close to its surface. The proximity switch consists of a transistor oscillator which builds up oscillations when a set value of capacitance in its resonant circuit is exceeded. The activating surface has a capacitor connected to a capacitance bridge, followed by an amplifier, resistance network and null volt switch. A change in external capacity causes the bridge to become unbalanced, the voltage amplified and activating the null volt switch which in turn opens a magnetic gas valve. Since there is a pilot burner, the main burner will ignite when being used and extinguish when not.

Title: Control circuit with microcomputer capacitor charge control - provides digital adjustment of pulse frequency and duty cycle
Inventor: KESSLER HEINRICH DIPL PHYS
IPC: G05B15/02
Filed: 1980-09-09
Abstract: The electronic control circuit has a capacitor (C1) which is charged up by digital impulses and discharged via a resistance dependent on an analogue physical parameter. The charge condition of the capacitor stands in equilibrium between the charge and discharge processes and is fed to a threshold switch (SW) used to trigger the control process, e.g. using a microcomputer. The frequency and duty cycle of the digital pulses controlling the charging transistor (T) can be adjusted in purely digital fashion. This is achieved by feeding the digital charging pulses to the capacitor directly through a microcomputer. The microcomputer has one output providing charging pulses directly to the control circuit to be fed to the capacitor via a resistor (R1). The threshold switch is driven by a low-pass filter (R2,C2).

Patent DE-3100235-A1 (DE)
Title: Method and device for detecting faults in a regular configuration
Inventor: LEAR EDWARD CHARLES
IPC: G01N21/89
Filed: 1981-01-07
Abstract: In order to detect faults in fabrics, such as e.g. tufted fabrics, it is proposed to scan an illuminated fabric surface by means of a light-sensitive apparatus (4) which generates a train of electric pulses, for example corresponding to a sequence of backstitches or ribs (7) protruding from the scanned surface. The pulses are monitored for irregularities and a warning signal is generated, e.g. as a function of the determination of a missing pulse corresponding to a missing backstitch. In order to avoid the generation of erroneous fault signals, e.g. in the event of changes in the surrounding level of illumination, suitable compensation measures are provided during monitoring of the pulses. For example filter arrangements can be used, or, as an alternative, a comparison can be carried out between the pulses and their slightly delayed versions, in order to facilitate an accurate identification of the presence of a pulse. In order to generate sharply defined pulses, the light-sensitive apparatus (4) receives the light reflected at right angles from the fabric surface via a focusing device, which has a diaphragm (12) with a slit (13) extending parallel to the backstitches or ribs (7). Furthermore, the fabric surface is illuminated at an angle relative to the surface normal. In order to check the pulses, their pulse length/interpulse period ratio can be monitored using square-wave and ramp signal generators. <IMAGE>

Title: Device for processing vulcanisable materials
Inventor: HEGELE KURT
IPC: B29C45/16
Filed: 1981-01-23
Abstract: A transfer moulding device for processing vulcanisable materials to form an article consisting of at least two parts which are spatially different from one another, the article not only having small dimensions but also consisting of a plurality of components of different materials and having relatively complicated shapes. In order to produce such articles, a transfer moulding device is described in which two different upper mould plates interact with a lower mould plate in such a manner that the first of the two upper mould plates together with the lower mould plate forms a first recess enclosing one part of the article, whereas the second of the two upper mould plates together with the lower mould plate and with the first part of the article, already located in the lower mould plate, forms a second recess which encloses the other part of the article. The two upper mould plates can be brought one after the other into a sealed engagement with the lower mould plate.
Patent DE-3105887-A1 (DE)
Title: Process for producing filter bodies, in particular for the fine filtration of fluids
Inventor: REINHARDT ERICH K DIPL CHEM DR
IPC: A61L2/02
Filed: 1981-02-18
Abstract: The invention relates to a process for producing inherently rigid filter bodies which are entirely composed of carbon. The process is intended to enable both the adsorptive behaviour and the filtration properties of such filter bodies to be determined in advance and thus to be able to produce application-specific filter adsorbencies. The filter bodies are intended to be suitable in particular for use at elevated temperatures and under chemical conditions which are compatible with carbon and to be able to be produced even in extremely large dimensions. To produce such filter bodies, a quantity of porous carbon particles is filled with a filler liquid. The filled carbon particles are then coated on their surface with a carbonisable binder which is not soluble in the liquid or immiscible with it. The filled and coated carbon particles are then compressed to form the filter body. The moulding formed as a result is then heated to remove the liquid present in the carbon particles and to harden the binder, this being permeated by pores by the evaporation of the liquid. Finally, the moulding, to carbonise the binder, is heated to still higher temperatures in a non-oxidising environment.
Patent DE-3111099-A1 (DE)
Title: Electrical switch
Inventor: RUNGE HERMANN
IPC: H01H35/02
Filed: 1981-03-20
Abstract: The invention relates to an electrical switch which consists of two shells which are physically separated from one another, have an edge which ends flat and whose edge regions are placed one on top of the other. The edge regions are, however, constructed such that the contact with the at least partially electrically conductive shells is interrupted. At least one freely moving, electrically conductive contact-making device is introduced into the space formed by the two shells resting one on top of the other, which contact-making device rolls in the edge region when the switch is in an inclined position and then bridges the electrically conductive parts of the two shells which rest one on top of the other.

Title: Arrangement for determining the projection of reinforcing steel along a locating track on the surface of a reinforced concrete structure
Inventor: HILLEMEIER BERND DR ING
IPC: G01V9/00
Filed: 1981-04-04
Abstract: The invention relates to an arrangement for determining the projection of reinforcing steel along a locating track on the surface of a reinforced concrete structure. The reinforcing steel is inductively heated by an alternating electromagnetic field. Thereafter, the thermal radiation of the reinforcing steel is measured. This is performed in such a way that a linear locating cable is arranged parallel to the locating track. Said cable has an electric conductor or a plurality of electric conductors connected in parallel. Connected to the locating cable is a feedback cable which is guided at a distance from the locating track. By using a suitable measuring instrument to investigate the thermal radiation after the heating, a determination is made of the projection of the reinforcing steel as points of intersection with the locating track, or as segments which extend parallel to the locating track. The orientation of the locating track can be arbitrary. <IMAGE>

Title: Hydraulic control device
Inventor: HOEFER FRIEDRICH WILHELM
IPC: B60T13/14
Filed: 1981-06-13
Abstract: The hydraulic control device according to fig. 1 has a flow control valve (16), a pressure control valve (B), a non-return valve (72), a brake valve (80) and a pressure accumulator (86) and a pump (12), by means of which the pressure accumulator and a hydraulic consumer (24) are supplied with fluid. The pressure control valve comprises a 2-position control slide valve (42) and a valve body (43), which are operatively connected by a spring (45). A flow of hydraulic control oil coming from the flow control valve flows via the pressure control valve to the tank until the pressure accumulator is sufficiently charged. Once the latter is charged, the flow control valve is adjusted by the pressure control valve so that now the connection to the accumulator is interrupted and the consumer (24) is supplied with fluid. <IMAGE>

Title: Excitation circuit for a piezoelectric oscillator
Inventor: MUELLER EDELFRIED
IPC: B06B1/02
Filed: 1981-07-03
Abstract: An excitation circuit for a piezoelectric oscillator is described, whose electrodes are connected to the secondary winding of a transformer and to a further inductance, the transformer being supplied from transistors which are connected in the push-pull mode, are connected to a DC power source and whose base connections are electrically coupled, via a series-resonant circuit, to the electrodes of the oscillator. In order to make possible electrically floating installation of the oscillator and of the horn in the case of the excitation circuit with relatively little circuitry complexity, it is provided that the series-resonant circuit is switched from a second transformer and a capacitor into a line which connects the base connections of the transistors, the secondary winding of the second transformer being connected in DC terms (directly electrically connected) to the electrodes of the oscillator.

Title: Elastic bearing arrangement for drive assemblies in motor vehicles
Inventor: BAUER JUERGEN ING GRAD
IPC: B60K5/12
Filed: 1981-07-29
Abstract: An elastic bearing arrangement for drive assemblies in motor vehicles comprises a first rubber-elastic bearing element on the drive assembly side and a second elastic bearing element arranged in an in line connection thereto. In order to obtain a low aggregate spring rate of the bearing arrangement so as to achieve a low resonant frequency of the drive assembly, the second bearing element is formed by a coil spring with a greatly reduced spring rate compared to the first bearing element. The low aggregate spring rate obtained for the bearing arrangement allows the rubber-elastic bearing to be optimised in terms of noise insulation, the high frequency oscillations (noises) originating from the drive assembly being efficiently damped in the rubber-elastic bearing. In the same way the low frequency oscillations originating from the road surface are also efficiently damped by the relatively soft coil spring in conjunction with a damping device connected in parallel.
Patent DE-3137321-A1 (DE)
Title: Electrical switching apparatus
Inventor: ERK ADIL PROF DR ING
IPC: H01H9/54
Filed: 1981-09-19
Abstract: An electrical switching apparatus has at least one contact arrangement (16, 26, 20) on which at least one switching arc is struck during switching off. This switching arc is extinguished by means of controllable semiconductor valves (52) which are allocated to the contact arrangement. In order to simplify the construction, the contact arrangement is constructed as a double-contact arrangement which is known per se and whose contact points (16, 26) open successively in time as a result of a controlled movement sequence of the double-contact arrangement, that contact point (16) which opens first having the at least one controllable semiconductor valve (52) connected in parallel with it. The double-contact point is constructed in a manner known per se as a contact link (20) which can be operated by a drive plunger (40, 42), the drive plunger acting on the contact link outside its centre of gravity during a switching-off operation, so that the point (50) at which it acts is closer to the contact point which is opened first. <IMAGE>

Title: Coin-operated gaming machine having a credit counter for the subsequent win payout
Inventor: GAUSELMANN PAUL
IPC: G07F17/32
Filed: 1981-10-05
Abstract: A coin-operated gaming machine is equipped with a win-reserve memory (16) which the player can selectively occupy, there being the possibility of an extra win shown by a bonus memory (19) which can be incremented during the occupation of the reserve memory (16) as a function of the content of the reserve memory (16), as a function of the game result, especially as a function of the game result which can be modified by means of a restart button (4), as a function of the state of a game counter activatable by the reserve memory (16). The memories (16 and 19) control the win payout indirectly after the reception of an interrogation signal. The interrogation signal can be formed by a game-result detector (5) or be triggered by the actuation of a button (29). The button actuation results in the erasure of the bonus memory (19). <IMAGE>
