Title: Anchoring members for artificial hip joint - has main shaft with enlarged top with hole tapped at angle for sloping pin
Inventor: ERLER FRITZ DR
IPC: A61F2/36
Filed: 1978-12-15
Abstract: The hip joint prosthesis with a spherical block (1'') mounted at the top, has a main member (2) which is inserted into the bone. This has a stem (5) with a larger diameter outer end (4) which carries the spherical block. A tapped hole passes through this larger diameter part at an angle to receive a pin (3) to the end of which is attached a further spherical portion. The smaller diameter part can be curved to match the natural curvature of the bone, and can curve away from the direction of the sloping topped hole. This part has channels (1') down it, and holes through it which communicate with the channels. The larger end has an equaliser hole down the middle and slots at right angles to this hole.

Title: Security gap for bottles - with breaking piece separating opposite-hand threads
Inventor: KORNFELD ANTON ING
IPC: B65D41/34
Filed: 1978-12-28
Abstract: The thermoplastic cap of a bottle or a can has a main female thread which engages the male thread on the bottle neck. A second female thread of great diameter near the rim of the cap is attached to the main thread by a breaking piece and has a thread of the opposite hand. A corresponding thread is fitted to a collar on the bottle neck. An opening turn on the cap therefore exerts a ripping force on the breaking piece, esp. of the thread on the second (safety) section has a smaller pitch and severs the safety section. The customer is thus ensured that he receives the contents in the original pack.

Title: Moulding sand regeneration - in vibrating tank with screens, air sifting, fluidised bed and coolant spiral cooling
Inventor: LINDER HERMANN J
IPC: B22C5/18
Filed: 1979-05-25
Abstract: Moulding sand in foundries is regenerated in a tank where the sand clods are broken up on an inverted come which is vibrated by an unbalanced mass. The sand grains have to move in a zigzag path under the constant action of vibration and are sifted in counterflow by an air stream. The sand is finally cooled in a fluidised bed and by a coolant coil in the tank bottom.

Title: Thin metal layer thickness monitor - uses electron raster microscope and energy dispersing X=ray spectrometer for specimen evaluation
Inventor: SCHUBERT HORST
IPC: G01B15/02
Filed: 1979-09-25
Abstract: The thin metallic layers, or films, to be measured are coated on a support. The measured specimen is inserted into an electron raster microscope, after which an analysis is carried out on the layer surface by an energy dispersive x-ray spectrometer. The ratio of the layer to the support lines forms the rate for the layer thickness, the latter being finally determined by a calibration curve. Pref. this curve is established using a metallographic polish of several specimens of different layer thicknesses. These specimens are treated in an electron raster microscope for measuring the line intensity of the tested layer in dependence on the support-.

Title: Road vehicle speed determination system - using directional microphones to measure frequency shift between two points
Inventor: MASLOWSKI STEFAN DR ING
IPC: G08G1/015
Filed: 1980-01-24
Abstract: Directional microphones located at the side of roadways are used to identify and measure the speed of passing vehicles. The system uses two directional microphones (I,II) set at an angle (alpha) to each other. As the vehicle passes, frequency spectrum signals are obtained that have fundamental frequency shift between the two points. The ratio of the frequencies at the second point to the first is equal to V.Sin(alpha)/C, where V is the speed and C is the velocity of light. Additionally, any vehicle generates a specific frequency spectrum that allows identification relative to other traffic.

Title: Flat heating element - has resistance wire formed into meander and sandwiched between two insulating webs
Inventor: SCHAUER FRIEDRICH ING GRAD
IPC: H05B3/36
Filed: 1980-02-01
Abstract: The heating element consists of a meandering resistance heating wire sandwiched between two insulating webs. A device is used to form the wire (1) into a meander shape. One loop of the meander is formed per stroke of the device.

Title: Voltage regulation with two level switching - uses relay controlled by transistor circuit to couple transformer secondary coil to lamp over two pick up points
Inventor: BAIER WOLFGANG DIPL ING
IPC: G05F1/20
Filed: 1980-03-28
Abstract: A voltage regulation system is used to control the secondary voltage of a transformer used to supply a consumer unit. The regulation is of a two level type with switch over being dependent upon the primary voltage. The system is particulary suited for application with projector lamp control. The secondary winding (2) has three tappings (3,4,5) that connects with a transistor circuit controlling a relay switching stage (7). The relay state determines whether the lamp (6) is coupled with either tapping (4,5). If the mains voltage rises above a set level, the transistor (15) is put into the conducting state and a second transistor (19) cuts off resulting in the relay dropping out. When the voltage falls the transistor states invert and the relay switches back.

Title: Fuel injection pump with reduced dimensions - employs one solenoid to control fuel quantity and also to turn off fuel flow
Inventor: FEHLMANN WOLFGANG
IPC: F02M41/12
Filed: 1980-05-21
Abstract: The modification to a fuel injection pump and distributor is intended to make the unit smaller and also use fewer components. The sliding valve (3) for controlling the fuel quantity injected at each stroke of the pressure pump (4), is set by a solenoid (15) acting against the force of a return spring (23). When the pump plunger (4) reaches a point where its relief channel (12) opens into the outlet (20) in the sliding valve (3) the fuel path is short circuited. Fuel flows back into the reservoir (8) and injection through the pressure channel (11) ceases. The slide valve is located on a pin (31) to prevent it from rotating with the pump plunger (4). With the solenoid off, the spring (23) pushes the slider (3) to a position where the relief path (10,12,21) is always open and flow to the engine ceases.

Title: Damming for enhanced mine-working gallery durability - involves sheathing and filling between plinth and roof, and embedding wooden piers
Inventor: BRAEMER LOTHAR
IPC: E21F15/00
Filed: 1980-06-13
Abstract: The gallery support lining is sealed towards the long face by mat warping and oilcloth, where a process is applied for enhancing durability of work face galleries, esp. in sloping deposits. The accompanying barriers are constructed from rapidly hard-setting materials. The gallery, in the form of base gallery (1), has a plinth (4) made of damming material inserted in it, before passage of the long face between the gallery bottom (2) and seam floor (3).
