Patent DE-2462150-A1 (DE)
Title: Modification of squirrel cage construction - incorporating additional slots to reduce cross currents between bars
Inventor: SABEV TODOR DIPL ING
IPC: H02K17/16
Filed: 1974-11-05
Abstract: In squirrel cage type rotors with non-insulated windings the operating characteristics and efficiency can be impaired by leakage currents flowing circumferentially between conductors. Operation is improved by the addition of intermediate slots (3) at least half the depth of the main slots (6). These slots are typically part filled with conducting bars ( 4) leaving an air space (5) at the bottom. Alternatively, the additional slot may be part of the main slot, amd be arranged so that only a small part of the conductor is in contact with the core punchings on one radial side. This design may be used to advantage on welded rotor windings.

Title: Speciment carrier for agglutination reactions - has mirror backed glass plate with ground glass mask surrounding each specimen holder
Inventor: BERNDT HELMUT PROF DR MED
IPC: B01L3/00
Filed: 1975-06-21
Abstract: The specimen carrier for agglutination reactions consists of a glass plate which has a reflecting surface. The surface can have a deposited mirror backing or a polished metal foil so that the glass plate is in the form of a plane mirror. The other surface of the plate is roughened by sand blasting or chemical etching to produce an opaque field. The specimen holders are formed by a pattern of uniform circles cut into the opaque mask so that each one becomes a circular mirror. Because of the sharp contrast between the mask and reflecting surface, observation of the reactions is considerably enhanced. The differential surface tension provided by the smooth glass area and its surrounding mask ensures that specimen fluids remain in their individual compartments.

Title: Forced air circulation oven - for the mass prodn. of moulded bricks using turbulent air flow
Inventor: STANASILA VIRGIL CORNELIU DIPL
IPC: F27D7/02
Filed: 1975-10-23
Abstract: The bricks or the like are fed downwards in vertical stacks through currents of preheated, turbulent air; and after a dried brick has been removed from the bottom of each stack, a new brick is placed on the top of each stack. In the pref. oven, air cushions clamp the second brick at the bottom of each stack while a hydraulic platform lowers the bottom, dry brick in each stack for removal. At least one end wall of the oven is reciprocated horizontally so hot air currents are reciprocated across the oven. The automatic plant requires little manual labour, and has high thermal efficiency.

Title: Mercerising fluid cleansing process - uses electrodes in a vertical tank as fluid moves downwards
Inventor: STIEBERT ARTUR ING GRAD
IPC: D06B23/20
Filed: 1976-03-16
Abstract: The process to regenerate mercerising fluid, and remove impurities, uses a vertical vessel for the used fluid to be passed in for storage. The soiled fluid passes in from above, while the clean fluid emerges from the base. Electrode grids are located between the inlet and outlet, spaced from each other. An overflow edge for the vessel is positioned above the fluid inlet. The system gives a low-cost process for removing impurities from used mercerising fluid. The impurities removed include substances accompanying cellulose, residual starch size, dyestuffs, alkaline and alkaline earth carbonates, polysaccharides and built-up cotton impurities.

Title: Solar heating panel anti frost water drainage circuit - employs drain tank with magnetic valve and drainage lines
Inventor: KRUMPE ALFRED DIPL ING
IPC: F24J2/40
Filed: 1976-04-02
Abstract: The solar heating system has an arrangement for draining the water from its heat collector panels (1) to protect them from frost. A top outlet (4) from the collector is fitted with a magnetic stop valve (5) immediately before entering an equalising tank (2). The upper level of this tank is below the safety level (X) under the bottom outlet (6) of the panel. A branch (3) in parallel with the top outlet (4) terminates at the bottom of the tank (2) below its lowest level. The circulating pump (7) is switched off in the event of frost, and the magnetic valve opened, so that the water in the panel drains into the tank. When the pump and valve are operated again, water enters the panel with normal circulation, and air from the panel enters the tank and not the water circuit.

Title: Anti skid braking control - has dynamic adapting control to set skid threshold w.r.t. retardation level
Inventor: BARBORA JAROMIR DIPL ING
IPC: B60T8/70
Filed: 1976-04-13
Abstract: The anti-skid control has a several control blocks with a first and second block generating the wheel speed and retardation/acceleration signals, from the outputs of the wheel speed sensors. A fourth block generates wheel skid signals, while a third block provides wheel translation signals. A comparator or summation circuit compares the outputs of the second and fourth blocks to control the action of the modulation valve. The system provides a variable skid threshold which takes into account the dynamic condition of the vehicle, and provides optimum braking over a wide range of speeds and grip.

Title: Rapid fitting automobile snowchain - has split metal hoop on inside of tyre and two segments on outside
Inventor: SANVITALE NICOLA
IPC: B60C27/14
Filed: 1976-04-27
Abstract: The snow chain has a series of transverse steps (11) linked by metal hoops on each side of the tyre. The inside face hoop is in one section (1) split at one place, while the outside hoop is in two half sections joined by chains. Fitting is a simple single handed process which does not require the wheel to be turned or lifted. The larger hoop is looped over the rear of the wheel, by twisting into an elliptical shape. This allows it to be pushed sideways over a wheel with close spacing from the body. The ends of the hoop are secured by a chain (4) tensioner, after which the outside hoops are secured by chain hooks.

Title: Amusement game with ball ejector - has overload clutch preventing blocking of operating mechanism by returning to original condition
Inventor: GAUSELMANN PAUL
IPC: A63F7/22
Filed: 1977-01-04
Abstract: Amusement game has an ejector for balls etc. The balls are released from a collecting container not accessible from the outside through a delivery movement of the collecting container initiated by an operating mechanism. The operating mechanism contains a return movement and a repeater lock. An overload clutch element is made as a circular plate segment capable of swivel movement with a clutch roller which adjoins its circumference under spring tension and which in its normal position is held inside an edge recess capable of being unlatched. The improvement ensures that the ejector cannot be locked by the clamping of balls etc., since the overload clutch returns the operating mechanism to its original condition.
