Title: Flexible bag as inner mould for tyre - has rigid internal support frames which articulate to collapse bag for removal
Inventor: VENTE PAUL
IPC: B29D30/06
Filed: 1980-11-12
Abstract: Core for moulding a pneumatic tyre is in the form of an extensible bag, open towards the centre of the tyre. This bag (4) is internally supported by bridge-like strips (5) at regular intervals around the circumference, each strip (5) is composed of several rigid components (5a,5b,5c) connected at articulations (6,7) and the two ends of the bridge are fixed to sliders (12) capable of axial movement. When the two slider (12) are pulled apart the articulations (6,7) open so that the bridges become flatter and shallower. Stops at the joints (6,7) are so adjusted that, when the two sliders are brought together, the external contour of the strips (5) agrees with the desired tyre internal contour and the stops bear against one another. An additional axial locking device (9) supports and fixes the strips (5) in the beading zone. Used as an internal core for the prodn. of tyres by casting, injection-moulding and centrifuging. The mould can be reused many times and a high deg. of uniformity in the prodn. of the tyres is achieved. The rigid bridges supporting the mould ensure that it remains in the correct shape even where centrifuging is not used. The appts. is inexpensive.

Title: Trigger-coupled radio-signal switch for radial-radio remote-control systems
Inventor: HARTMANN HEINRICH
IPC: G08B5/36
Filed: 1981-01-31
Abstract: The switch, which is mounted in the rifle grip and is coupled to the trigger mechanism carries out switching processes (during operation of the rifle trigger) which cause the transmission of various signals - ready to fire messages to the gunner's operations centre - via a connecting line to the radio-signal transmitter. During operation of the trigger, the switching processes run in a positive manner and simultaneously, and additional handles for operating a switch are obviated. This thus avoids the gunner being distracted during the aiming process.
Patent DE-3116303-A1 (DE)
Title: Hydraulic lifting appliance, in particular for erection decks
Inventor: TIRRE JOHANNES
IPC: B66F11/04
Filed: 1981-04-24
Abstract: The invention relates to a hydraulic lifting appliance, in particular an erection deck with a boom linked to a perpendicular rotary column and pivotable about a horizontal axis. A platform, preferably an erection deck likewise pivotable about a horizontal axis, is linked to the free end of the boom in such a way as to be held horizontally. Since workers work on the erection decks and are thus moved into favourable erecting positions, the erection deck must be held exactly horizontally in every operating position of the boom. In known lifting appliances this is achieved by parallelogram bars. The linkage of the parallelogram bars prohibits the use of telescopic booms, so that the erection decks can only be moved on radii. According to the invention the erection deck is moved by a command sequence cylinder and is held in the horizontal position. The command sequence cylinder is influenced by a command cylinder which works as a function of the boom swivelling. This results in the advantage that the boom itself is telescopic; for a parallelogram-bar linkage is dispensed with. <IMAGE>

Title: Ring of caps for toy weapons
Inventor: SCHOCHINGER AXEL
IPC: F42B39/08
Filed: 1981-05-06
Abstract: In the case of a ring of caps for toy weapons, a plurality of retaining bodies (11) are arranged distributed uniformly on its circumference. Located between in each case two adjacent retaining bodies is a gap (12) which is large enough for a retaining body (11) to be fitted in between. Arranged underneath each retaining body (11) is a hole (13) in the carrier (10), the holes (13) all lying on the same partial circle. Retaining studs (14) are likewise arranged on this partial circle, which retaining studs (14) project out of the carrier (10), as integral components, in the same direction as the retaining bodies (11) and rest on the bisector of the dividing angle of the retaining bodies (11). The retaining studs (14) are constructed in such a manner that a subregion of their shaft corresponds to the shape and size of the holes (13). Two such carriers (10) fitted with retaining bodies (11) can be joined to one another to form a ring unit and together form an ammunition item having twice the number of retaining bodies (11) of a single carrier (10). <IMAGE>
Patent DE-3119316-A1 (DE)
Title: Front plate for a driving-in tool
Inventor: DONAUER HORST
IPC: B25C1/00
Filed: 1981-05-15
Abstract: The invention relates to a front plate for a driving-in tool for staples and the like, in particular for the direct or indirect fastening of panels and boards in interior finishing. In accordance with the accident prevention regulations, driving-in tools of this type generally have a safety feature to prevent unintentional release. This safety feature often consists of a pin, the pressing-in of which enables the driving-in tool to fire. The pin must therefore project beyond the end of the firing passage. Consequently, it is a hindrance to many tasks in fastening technology. The object of the invention was to create a driving-in tool with a movable front plate which is effective as an anti-release safety feature and in which no safety pin projects beyond the end of the firing passage. The object was achieved by the front plate belonging to the firing passage being movably mounted and being in operative connection with the safety pin. The connection between front plate and safety pin is to be releasable.

Title: Arithmetic device for determining an operand to be formed from the integral of a measurement voltage
Inventor: RENG LEONHARD DIPL ING
IPC: H02P21/10
Filed: 1981-09-25
Abstract: The measurement voltage is supplied to the converter (5) via a smoothing section (4). The transfer characteristic of the smoothing section is compensated for by appropriate design of the subsequent circuit sections. This compensation can be achieved by means of a differentiating circuit arrangement or - if the arithmetic circuit contains an integrator (12) for the converter output quantity u' at the input (7) - by connecting a circuit to the integrator. This makes it possible largely to suppress the measurement errors of the converter if the measurement voltage decreases with decreasing frequency as is the case, for example in rotating-field machines driven in a field-oriented manner. <IMAGE>

Title: Demodulator for a frequency shift-keyed input signal
Inventor: WIEGEL MANFRED
IPC: H04L27/156
Filed: 1982-03-13
Abstract: The demodulator according to the invention contains at its input a receive filter (1) which determines the transient response and changeover response of the frequency shift-keyed receive signal. On the basis of final counter readings (Zn) which are proportional to the lengths of the half periods of the receive signal, the computer (6) calculates the frequency shift keyings and, through linear extrapolation based on the slope of the frequency shift keying predefined by the receive filter (1), the exact times of the frequency shift keying. A delay circuit controlled by the computer (6) switches the output signal (A) of the demodulator with a constant delay in relation to the calculated time of the frequency shift keying over to the respective opposite significant condition. <IMAGE>

Title: Heat-pump/external absorber/evaporator system for facades, house roofs, fences or the like
Inventor: KELLER GERHARD ING GRAD
IPC: F24S10/75
Filed: 1982-03-19
Abstract: Heat-pump/external absorber/evaporator system for recovery of heating energy for buildings of all types, consisting of energy-exchanger surfaces which can be designed as facade cladding, house roof, fence or the like, refrigerating means and brine distribution system, fastening construction and heat pump. In contrast to conventional processes, the working substance of the heat pump is injected, pumped or otherwise brought into the energy-exchanger surfaces developed specially for this purpose, without interconnection of an additional heat exchanger. At higher absorber temperatures, an additional brine circuit can transmit the energy directly via an additional heat exchanger to service water or heating water. Specially shaped energy-exchanger surface profiles made of aluminium guarantee a very good transfer of environmental energy to the working substance flowing in them. By this method, energy losses, which occur in the case of an additional heat transfer of conventional brine installations from the brine to the working substance of the heat pump, are avoided.

Patent DE-3213311-A1 (DE)
Title: Sensor head of an electrochemical sensor
Inventor: SCHULER PETER DR
IPC: G01N27/49
Filed: 1982-04-08
Abstract: The sensor head is formed as a single-piece screw cap (1) which embodies the electrolyte space (3) which is sealed, on the one hand, by the membrane (4) on the end face side and, on the other hand, by the interaction of a sealing lip (12) with an annular groove in the direction of the sensor body. On interacting with the annular groove, said sealing lip (12) also acts as a stop member for fixing the axial end position of the screw cap in relation to the sensor body. The electrolyte space is consequently sealed essentially simultaneously when the screw cap reaches its axial end position, thereby preventing any overpressure in the electrolyte which could result in an overextension of the membrane and in lifting-off of the membrane from the measurement electrode. The membrane is clamped by means of an essentially dimensionally stable sealing ring (8) which pulls the circumferential edge of the membrane into an annular receiving groove (7) in the end face (6) of the screw cap. <IMAGE>
