Patent DE-2513538-A1 (DE)
Title: Gas valve with axially moving plunger - tapered end of plunger has O-rings controlling flow through plunger restriction
Inventor: HAYES STEPHEN
IPC: F16K3/32
Filed: 1975-03-26
Abstract: The valve has a rotary sleeve containing an axially movable plunger (30) whose tapered end (34) contains an axial passage (42) leading to radial outlets (40) opening between a pair of O-rings (36, 38). The plunger has a radially projecting pin (66) extending through a spiral groove in the sleeve so that rotation of the sleeves causes axial movement of the plunger. The tapered end of the plunger controls flow between a passage (18) and a lower passage and by adjusting the plunger so that the O-ring nearer the end of the plunger engages the inner surface of the passage a low flow rate can be produced, with gas flowing through the axial passage (42) and the radial outlets (40).

Title: Anti-theft arrangement for protecting valuables in showcases - has actuators for tipping valuables into container and returning case bottom
Inventor: HIRSCH AXEL
IPC: E05G5/00
Filed: 1975-04-26
Abstract: The antitheft arrangement for protecting valuables for example in shop windows and other showcases ensures that in the case of theft warning alarm the valuables, for example in showcases, are removed from within the reach of the thief. The support panel (2) for valuables such as jewelry is tilted by a pressurised medium actuated cylinder (6) about a horizontal axis (4). The valuables are tipped into a collecting container (5) under the support panel. The support panel can be split into a number of tilting units. The double acting cylinders return the tilting panels after a certain delay back into closed position. The panels are locked in closed position by locking bolts.

Title: Solubilising waste thermoplastics for mixing with hot binders - by comminuting and calendering at low temp. for use as cable cladding caulking corrosion protection adhesives road building
Inventor: PELZ DIETHART ING GRAD
IPC: B29B17/00
Filed: 1975-05-23
Abstract: Thermoplastics slightly soluble in heated binders, esp. for working up waste prods, are prepd. by comminuting the material and then bonding it at below its m. pt. range by rolling all or part of it into a layered structure. The thermoplastic is pred. waste polyethylene and the rolling temp is pred. room temp. to 70 degrees C esp. 50 degrees C., for 5-15 mins. The rolled thermoplastics is opt. comminuted again before addn. to the binder at above the binders m.pt. range esp. 110-190 degrees C. Conductive or non-conductive fillers may be added. The prepn. is used to add the rolled and opt. comminuted thermoplastics to a meltable polymer such as polyisobutylene, atactic polypropylene or other material for use as corrosion protectives, masonry protectives, adhesives, hot casting masses, caulking agents, and in road building. Esp. for cladding aluminium or steel tubes. Conductive mixts. useful for cladding cables and conductors to give high cross-conductivity between single wires in zero conductors. Previous difficulties with insolubility of the thermoplastics in the binder are overcome. The pour- pt. and softening pt. of the thermoplast in the prepd. prods. are raised and the plasticity range broadened. The solubility rate of the thermoplast is high.

Title: Arc welding cutout control - ensures burn-clear by relay in wire feed motor braking current circuit
Inventor: HESSE GUENTER DIPL ING
IPC: B23K9/12
Filed: 1975-05-31
Abstract: The cutout control for the wire feed and the welding current supply of an arc welding plant with a consumable electrode, using a d.c. wire feed motor, must ensure that the filler wire can burn clear prior to a cutout. A burn-clear relay with an iron core and a reed switch is arranged in the braking current circuit of the wire feed motor. The contact lies in the control circuit for the welding current supply, the relay coil can be a brake resistor in the armature circuit of the d.c. motor. This ensures that the filler wire burns clear independent of the set welding parameters and never freezes into the pool. Subjective interference by the welder is eliminated and the control functions reliably.

Title: Measuring thermo:efficiency of hydraulic pump - has throttle and pressure chamber with constant:temperature fluid around sensing points
Inventor: HOEFFLINGER WERNER
IPC: G01L3/26
Filed: 1975-12-18
Abstract: Measuring device for the thermodynamic efficiency of an hydraulic pump comprises a throttle, a pressure vessel and a shut-off valve in a by-pass to the pump, leading from the high to the low pressure side. Temperature sensors are upstream of the throttle and inside the pressure vessel. The spaces containing the sensors are wholly or partly surrounded by jackets (19,21) through which pressurised fluid at constant or nearly constant temperature flows, to eliminate heat loss which would affect the measurement. This may be achieved by a secondary circuit (18,21) containing a high pressure chamber (19) around the sensing point upstream of the throttle and a low pressure chamber (21) around the pressure vessel. This circuit may contain a secondary throttle (20) and a further temperature sensor (23).

Title: Shock absorber for spur gear - has inclined teeth with compression spring next to axially movable gear wheel
Inventor: HOFBAUER PETER DIPL ING
IPC: F16H1/04
Filed: 1976-02-05
Abstract: The shock absorber is for worm gears and helical spur gears and consists of axial compression spring (9) which is placed next to and in line with one of the spur gear wheels (3). The gear wheel is keyed to the shaft (6) in such manner that it is free to move axially. When the gears start to transmit a torque, the initial shock tends to set up an axial force on the gear wheel. To dampen this shock and the related axial movement of the gear wheel (3), the compression spring (9) is provided. In the case of the worm gear, the damper spring is located next to the axially movable worm.

Title: Cover cap for illuminated scale for sextant - of transparent material with reflective coating
Inventor: SCHNAUSE ROLF
IPC: G01C1/08
Filed: 1976-03-02

Title: Variable extension filter with replaceable clean water container - with perforated filter tubes and filter meshes on either side
Inventor: ZINNER EGON
IPC: B01D29/00
Filed: 1976-03-30
Abstract: Filter for water comprises a housing, a cover and a replaceable clean water container for mounting perforated filter tubes and filter meshes, and for receiving and conducting away the clean water. The container can be fitted or used with filter tubes and meshes on both sides, to double the filter output.

Title: Anode for electrochemical processes - using outer layer of manganese dioxide contg. lead dioxide and/or vanadium pentoxide
Inventor: TREPTOW WOLFRAM DIPL CHEM DR
IPC: C25B11/04
Filed: 1976-06-25
Abstract: The parent patent describes an anode for electrochemical processes, consiting of a carrier made of metal which can be electrochemically passivated. Mtal is covered by a layer of the nitride of metal and then by a layer of MnO2. In this addn. the MnO2 also contains PbO2 and/or V2O5, where the mole. ratio MnO2:(PbO2 and/or V2O5) is 1:1 to 9:1.

Title: Frequency-stabilised microwave oscillator - has resonant active element between load and half wave line leading to stabilising resonator
Inventor: BUECHS JUST-DIETRICH DR ING
IPC: H03B5/18
Filed: 1976-07-06
Abstract: The frequency-stabilised microwave oscillator has its resonant active element (0) between the load (L) and a stabilising resonator (R). The half wave line (1) joining the active element to this resonator has an attenuating impedance (D) at its centre. The attenuating impedance is chose so that the active element just begins to oscillate at the wanted frequency. The load is coupled via a quarter-wave transforming line to the active element. The advantage lies in producing a relatively high power over a relatively wide frequency band.

Title: Vacuum pressure die casting, esp. of aluminium - where evacuated vessel carries metal from furnace to injector barrel
Inventor: REIS WALTER
IPC: B22D39/02
Filed: 1976-08-14
Abstract: Metals, e.g. Al, are pressure die cast in an evacuated die, where contact between the molten metal and air is hindered between the melting furnace and the die. The pref. plant includes a transport vessel fitted with a valve on its bottom end, consisting of a ball mounted on a spring-loaded rod. The vessel is evacuated, then filled with molten metal via the valve. The full vessel is inserted into a connecting chamber fitted on the barrel of the die casting machines. The chamber and the die are evacuated; and a plunger then drives the molten metal fed into the barrel into the die. The die consists of a stationary and a moving half; and the two halves form a narrow, water cooled riser leading to a vacuum pipe. The metal solidifies in the riser so that it is not carried into the vacuum pipe.
