Title: Puncture needle for artificial kidney haemodialysis - with elliptical needle tip for smaller incision wound
Inventor: TERSTEEGEN BERND DR
IPC: A61M5/158
Filed: 1974-11-04
Abstract: The bevelled tip (2) of the cannula is an oblate ellipsoid shape. Pref. openings (4) are formed in the needle near the tip and consist of long slits running out into pointed edges. The cannula is made of metal, i.e. cadmium- or silver-plated fine steel, which is much less likely to cause inflection at entry point than a plastic needle. The oval tip produces a much smaller semi circular incision in the vessel wall than the normal needle of similar shaft diameter thus producing less scar tissue and less bleeding after removal from the vein. When formed the short axis of the ellipse is only one third to two thirds of the origonal diameter.

Title: Blower control system for transformers - to indicate non function by an electric system operated by a generator fitted to the blower shaft
Inventor: LEPPER WILHELM DR ING
IPC: H01F27/08
Filed: 1975-01-22
Abstract: Blower control system with a small current generator either directly or indirectly connected to the blower blade shaft which means that the generator is either superimposed, attached or fitted to a gear system. Alternatively one or more permanent magnetis are fitted to the blower blades which induce rigidly fixed spools located opposite connected to a measuring, indicating or switch-off control system. Damage is prevented to large transformer installations in the event of individual blowers not operating for any reason thus endangering the operation of the transformer in particular when it is operating under high load conditions when its warming up period is relatively short.

Title: Inlet air filter for reciprocating compressor - is combined with pulsation damping reservoir containing preheating coils preventing condensation
Inventor: LINDE ROBERT VON DIPL ING
IPC: F04B39/16
Filed: 1975-04-02
Abstract: Air is extracted from a system through a coarse filter (6) and passes through a flow meter (5) into a reservoir vessel (3). This has a capacity at least equal to twice the throughput per second of the compressor. The air enters the vessel through a central cylindrical tube (4) of fine filter material and leaves the vessel to enter the suction pipe (2) of the reciprocating compressor (1). The discharge of the compressor is taken through a coil (7) inside the reservoir (3) before being exhausted to atmosphere (8). The reservoir reduces pulsation in the inlet and protects the flow meter from damage. In combination with the filter reduces the space occupied by the installation and the heating coil prevents moisture condensing in the compressor inlet.

Title: Cock for handling liquid foodstuffs under vacuum - has plastics body and plug with integral lip seals
Inventor: PINKERNELL HEINRICH
IPC: F16K5/02
Filed: 1975-06-27
Abstract: The three-way cock is intended for handling liquid foodstuffs, such as milk, under vacuum. The cock body (1) has three connections (2, 3) and a tapered transverse bore (9). The plug (5) has a matching taper (12) with lip seals (10, 11) at each end. A screwed cap (6) is screwed against the body (1) with a clearance (13) between cap and plug (5). All three parts of the cock (1, 5, 6) are made of high molecular low density polyethylene. This ensures that the lips (8, 10) are sufficiently flexible to seal under atmospheric pressure. Also the co-efficient of friction between plug (5) and body (1) is low so that the cock can be easily operated by the level (17) attached to the shaft (16) of the plug (5).
Patent DE-2535635-A1 (DE)
Title: Torque aid for bicycle pedal - with extending link which lengthens effected crank radius to lower gear
Inventor: DANZER FRANZ
IPC: B62M1/36
Filed: 1975-08-09
Abstract: The pedal (h) is linked to the crank arm (a) by a special spring loaded link (f). This extends the effective length of the crank if the pedal is pressed hard on the downstroke. The link can also be clipped up to lock the pedal flat on the crank arm to prevent the machine from being stolen. The extending link operates only on the downstroke and prevents the pedal from hitting the ground. It provides a smooth take-off from standing and effectively reduces the gear ratio for hills.

Title: Crack detection and monitoring system - has embedded conductor and has electrical, optical or pressure-sensing transducer
Inventor: AFFOLTER PETER DR
IPC: G01N27/20

Title: Tool holder for throw away bits - has bit clamped on holder by pin tilted under screw action
Inventor: GUSTAFSSON MANFRED WALLACE
IPC: B23B27/16
Filed: 1975-10-07
Abstract: The tool bit is clamped by a pin with a shoulder, a part spherical and a conical section. The clamping screw has a part conical section, the cone angle of which is equal and opposite to the angle of the cone on the first pin. The cylindrical pin is placed at an angle between the conical sections of the first pin and the clamping screw so that the first pin is forced down, when the screw is tightened, and at the same time tilted over. As the pin is forced down, the shoulder of pin clamps the tool bit. As the pin is tilted, the top section of the pin will force the diamond shaped tool bit over into a corner, so that it is positively located.

Title: Automatic SLR camera with interchangeable lenses - uses array of pegs and digital switches for F number
Inventor: MURAKAMI HIROYASHU
IPC: G03B17/04
Filed: 1975-10-16
Abstract: The SLR camera is provided with TTL exposure control and with interchangeable objectives. The exposure settings are linked to the inbetween lens shutter of the objective by movable tags (19, 20) linking the objective to the camera. The objective is identified by special markings (15, 16) so that when it is fitted to the camera the markings are read by monitors and appropriate correction made in the automatic exposure control. For a fail-safe identification the markings are arranged in a digital code and are read by an array of switches. This eliminates any error due to misalignment of conventional cams, which must be accurately made and positioned.

Title: Wall covering modules - with multiples of basic unit for dimensions and distance between centres of fixing slots
IPC: E04B2/86
Filed: 1975-11-20
Abstract: Wall facings (e.g. brick, tile, polystyrene, polyurethane, plaster etc.) are made in modules of size, thickness, and distance between T-slot centres in multiples of 62.5 mm for economy and ease of construction. The modules are used with peg connectors and suitable quality concrete to produce insulating systems of concrete walling for complete buildings. The modular unit dimensions are such that the facings fit all corners, bonded joints, ends, niches etc. without wastage; part-modules can be used. The modules are tongued and grooved enabling walling to be mounted parallel using the peg connectors mentioned with concrete infill. The T-slots are visible dimensional units rendering measuring unnecessary; they are break-off lines for dividing into fractions of a module and they provide good keying for concrete.
