Patent DE-2604897-A1 (DE)
Title: Shoulder rest for violins and players - adapts in width to any instrument and in depth to neck and shoulder (NL130876)
Inventor: WOLF WILHELM
IPC: G10D3/18
Filed: 1976-02-07
Abstract: Of the usual clips (13) that attach the shoulder rest to the instrument-spaced studs (14) opposite wider-spaced hooks (15) - the outer one is attached (10) to the one end of the padded shoulder plate, while the inner one is attached to a horizontal rod (6) which slides in a horizontal friction collar (4) near the other. The rod is long enough to adjust the width between the chips to suit any instrument from a child's first violin to a full-sized viola. A two-piece (11, 12) screw at the inner end adjusts the depth of the rest to suit the playerhs neck. At the outer end, the effect of a similar screw is augmented or diminished by the length of the reversible L-shaped bracket (19) it fits into.

Title: Seed-contg. wadding with carrier sheet - to give mechanical strength
Inventor: ZEISS KARL REINHARD
IPC: A01G1/00
Filed: 1976-05-14
Abstract: In a new biologically active wadding having a carrier to provide mechanical strength, there is applied to the carrier a biologically active coating contg. seeds, nutrients and, optionally, fillers, these being held together by means of a binder, and both the carrier and the coating are porous. The product can be applied to various surfaces requiring plant cover, whether for ornament, prevention of erosion, or use as e.g. a sports surface. The product is light in weight and easy to lay. In some cases it can even be laid on ground without any humus layer (e.g. on rock or on concrete). The new product contains no soil or humus. In certain cases, the product can promote the deposition and retention of dew, so that it is particularly suitable for use in arid regions.
Patent DE-2625775-A1 (DE)
Title: Synchronisation separator for recorded composite TV signals - has two MOSFET switches allowing easy setting of separation level
Inventor: SCHOLZ WERNER DIPL ING
IPC: H04N5/08
Filed: 1976-06-09
Abstract: The synchronisation pulse separator, for recorded composite TV Signals, has the composite signal passing one way directly to a first MOSFET changeover switch and the other way via a clamping MOSFET switch to the second input of the first switch. The first switch is controlled by the blanking pulses and its output contains the composite signal minus the synchronisation pulses. The control signal for the clamping switch is derived from the composite signal. The advantage lies in the cut-out level for synchronisation pulse separation being easily set and stable.

Title: Doping silicon wafer with arsenic by diffusion - in evacuated hermetically sealed capsule with silicon arsenide crystal as dopant source
Inventor: ISHIGURO SABURO
IPC: H01L21/223
Filed: 1976-07-30
Abstract: In the diffusion of As into Si wafers (I), (I) and crystalline SiAs and/or SiAs2 are sealed hermetically in a capsule under vacuum and heated to the required temp. for a predetermined time. Doping is carried out in an closed space in the absence of moisture and oxides and an accurately predetermined doping profile is produced, without crystal disclocations on the surface of the wafer. Crystalline SiAs and SiAs2 are chemically stable at room temp. and the vapour pressure is only 1/3000th that of As. In an example, 0.2g SiAs crystal and 5 p-Si wafers (dopant concn. 1 x 1018 cm-3) were placed in a 100 cm3 quartz capsule. After heat treatment in vacuo for 30 min at 500 degrees C the capsule was sealed and kept 1 h at 1000 degrees C. The resultant Si wafers had a mirror-smooth surface, a diffusion depth of 0.3 mu m and a surface concn. of 2 x 1018 cm-3.

Title: Coin tester with frame forming coin guide - has balance and latch with projection and stop passing only correct size coins
Inventor: MARTIN BART GEORGE
Filed: 1976-12-13
Abstract: the coin tester has a frame that forms a coin guide. A swingable balance (16) with arms is hinged on the frame for coin (A) feeding. A latch (24) is installed near the balance (16) and hinged on the frame. The latch has a projection for coin (A) sensing, so that the latch (24) is deflected and the distance between the projection an arm on the latch increased. A stop (33) on the frame limits the latch (24) deflection, thus fixing the max. distance between the projection and the arm on the latch. This ensures that only correct size coins can pass, while all others are stopped.

Patent DE-2717409-A1 (DE)
Title: Thermonuclear pump for large scale fusion - has highly conducting tubular casing to improve electromagnetic pinch
Inventor: STROBEL CHRISTIAN DIPL ING
IPC: G21B1/00
Filed: 1977-04-20
Abstract: The parent patent describes a thermonuclear pump for large scale fusion, utilising either the thermal energy or the neutron avalanche produced by microfusion of the Los Alamos fusion test type. This enables a subcritical mass to be detonated. In this patent of addition, the plasma guide tube is of electrically conducting material (such as Cu, al or Ti) and is equipped with external electrodes at its ends, connected to a HF source. A HF short-circuit current flows along the tube, producing magnetic field lines, surrounding the tube and interacting with the magnetic field lines of the negatively and positively charged particles of the plasma flowing in a continuous direction along the tube. The effect is to produce an electromagnetic pinch upon the charged particles, forcing them with an alternate but very high frequency action towards the core of the tube, the hotter components being towards the centre of the cooler around the periphery. Collectors mounted insulated inside the tube near the external electrodes are connected to a DC or AC circuit which is thus supplied with the energy from the kinetic inertia of the plasma. The pump can be used as a reinforcing cartridge in plasma reservoirs, fusion reactors and plasma lasers. By substituting Cu, Al or Ti for the ferromagnetic pole change reinforcement of the parent patent, a much higher frequency is obtd. of the pole change relative to the fast-flowing plasma.

Title: Blockable hydraulic and pneumatic lifting jack - uses piston rod to actuate overflow passage in piston
Inventor: SCHAEFER JOSEF
IPC: F16F9/02
Filed: 1977-06-15
Abstract: The lifting jack has a cylinder with piston and rod, with its free rod end passing through a sealed guide at one cylinder end. The piston and rod are charged in the out direction by the hydraulic operating medium, and a gaseous compensation medium.

Title: Voltage ratio monitoring network - changes state when defined ratio occurs and has summing network connected to multiplier circuit
Inventor: LANIK HANS
IPC: G01R19/10
Filed: 1977-07-28
Abstract: A network is used for monitoring the ratio of two input signal voltages which change state when a certain predefined ratio occurs. The system is accurate, stable and has accurately defined hysteresis. The circuit is more accurate than a combination of Schmitt triggers which can be used for this purpose. The incoming signals (U1, U2), are fed to a summing network (3) the output of which is fed to a multiplier circuit (6) to which a sign signal derived from a comparator (4) is also fed. The output of this is fed with one input to a further analogue comparator (7) and this feeds the sign comparator (4) in a feedback loop which latches and unlatches at accurately defined levels in the manner required.
