Title: Housing for supply line for dental hand tool - has winding drum driven by electric motor
Inventor: WIESER ALFRED
IPC: A61G15/16
Filed: 1976-04-10
Abstract: The housing for supply line for dental hand tool comprises a drum (7) for winding up the supply line, and an electric motor (1) which is connected to the drum via transmission means e.g. a drive belt (4, 5, 6) and which produces tensile stress in the supply line (8) at the drum. Tension is pref. constant over the whole winding zone of the supply line and is maintained even when the tool (9) is inserted. It may be increased or decreased during operation of the tool, when the tool is switched on, mechanically e.g. by locking the drum with a brake (18) and/or by disengaging the transmission means, or electrically e.g. by varying power supplied to the motor or by switching the motor off.

Title: Compression ignition engine fuel pump - has superimposed staged double piston arrangement with spring loaded second piston
Inventor: SCHEYING HEINZ
IPC: F02M45/06
Filed: 1976-07-27
Abstract: The IC engine fuel injection pump has a superimposed arrangement of two pistons. The piston controls the working space. The second piston is spring loaded and has a longitudinal orifice which interconnects the pump working space with the pump pressure chamber. The second piston has a pressure contact area which after closure of a control orifice in the first piston isolates the piston spaces and thus generates a steep sudden rise in the working pressure of the pump. Both pistons have a staged configuration, and the annular contact area, contacts a counter stop at a free clearance distance between the two pistons.

Title: Knitting machine needle design - has a sliding sinker in each needle shrouding to allow working of all yarns without stitch tension
Inventor: BOSCH JUAN
IPC: D04B35/06
Filed: 1977-02-10
Abstract: A needle system is for use with single or double-bedded flat bed or circular knitters, for the mfe. of single or double jerseys, looped knits, interlock or Jacquard fabrics. Special and purely mechanically operating needles are in rectangular shroudings which are channel in both upper third sections. The needle head is shaped a hook to grasp the yarn. The longitudinal and rectangular shrouding has a U-shaped cross section with an internal longitudinal and rectangular sliding sinker with a butt projecting from the body of the needle, the butt and sinker being an integrated unit with space allowed for the projecting butt. The needle has a lower butt to be operated by cams to raise and lower the needle, while adjustable stops act on the sinker butt to open and close the hook. Limit stops are positioned in the channels to determine the amount of movement i the reciprocating action of the needle. The design allows fabrics to be knitted from natural synthetic fibres, even fine gauge yarns, giving a fabric with a soft handle and without applying stress to the stitches.

Title: Power supply for electronic appts. - is derived from photocells connected to two=stage storage capacitor system
Inventor: KRAUSE GERHARD
IPC: H02J15/00
Filed: 1977-07-18
Abstract: The power supply is chiefly intended for small appliances such as pocket calculators, measuring instruments, and clocks. Light energy is converted into electric power by photovoltaic cells (F1-F32). These are normally arranged in two banks of opposite polarity. Each is directly connected to a first stage capacitor (C1, C2) and, through a voltage sensitive switch (T1, T2) also to a second stage (C3, C4). The switches are arranged so that the second stage is connected only when the first stage has reached a set voltage level. By using two stages the appliance can be ready for use quicker than would be the case if a large capacitor has to be charged. The power supply demand is switched to the second stage capacitors when these in turn have reached a set voltage level.

Title: Controlled component removal from power press - operates using oscillating parts separator and belt conveyors
Inventor: KUJAWSKI ULRICH
IPC: B21D43/22
Filed: 1977-10-27
Abstract: Components (5) which are punched out of a continuous supply strip, are ejected from the punch tool through the matrix (4). When they leave the matrix, they are received by a separator (6) which oscillates horizontally. The separator drops the components (5) one by one, onto a horizontal exit conveyor (13) such that a gap exists between the components. The exit conveyor (13) discharges the parts (5) into a vertical stacking duct (17). When the stack reaches the required height, an elevator (25) lowers it onto a second conveyor at a lower level.

Title: Fluid flow rate transducer - uses obstruction induced vortices to measure frequency representing flow rate
Inventor: GUILLERM HENRI
IPC: G01F1/32
Filed: 1978-03-03
Abstract: An accurate industry orientated fluid flow transducer is such that obstruction is placed in the fluid flow path so that eddies or vortices are formed and the frequency of these measured to give a measurement of the fluid flow rate. A rectangular or trapezoidal obstruction (11) is placed in the flow path of the fluid in a pipe section (10), so that vortices are formed in the fluid as it flows over the sides (20, 21) of the obstruction. Liq. filled ducts in the obstruction, transmit alternating pressure signals caused by these vertices via flexible leads (30, 31) to a pressure difference transducer (32) and thence to via a monostable multivibrator (34) to a frequency measurement network (35) and display (36). Membranes isolate the internal obstruction liq. from the fluid under examination.

Title: triple-pass water boiler - has second pass divided into streams of different heat transfer to set mix temp.
Inventor: BOEDER WILFRIED
IPC: F22B21/26
Filed: 1978-08-18
Abstract: The combustion products leaving the combustion chamber of a steam or hot water boiler are divided into separate streams and pass through smoke tubes in which differing degrees of heat transfer take place. The streams are then brought together and assume a temp. resulting from the mixing of the streams of differing temp. from the smoke tubes. The proportion of gases passing through each set of smoke tubes is regulated to give a controlled final temp. in accordance with the temp. requirement of a separate installation e.g. a wood or mineral drier, a part of the flue gases being drawn off and passed through this installation. The remaining gases flow through the third pass of the boiler, giving up heat to reduce their final temp. to the exhaust temp. To minimise draught changes which might adversely affect the combustion efficiency of the burner, the control automatically regulates, pref. by dampers in the various smoke passes, so that a constant pressure is maintained in the combustion chamber.

Title: Container frame enclosing tank esp. transporting milk etc. - supported by filling of polyurethane foam avoiding heat bridges
Inventor: BOEHM PETER DIPL ING
IPC: B65D88/12
Filed: 1978-12-28
Abstract: Between the surface of a tank and a container frame, bearing surfaces are formed by a layer of foamed synthetic material. There are at least openings in the synthetic layer for the filling and draining connections of the tank. Corner zones of the container frame are left free of the synthetic material. At least the main surfaces of the frame are clad with sheets of metal or similar and the spaces between the tank and the plates is filled with foam. The arrangement rules out the formation of heat bridges which particularly in the case of foodstuffs can be harmful, and the tank floats in the frame so that the accelerating forces are transferred safely from the tank to the frame.
