Title: Indicator mechanism for measurement instruments - is for interval switching and has two independently set demand value indicator shafts
Inventor: WIEBROCK GUENTER
IPC: G01D13/26
Filed: 1979-04-02
Abstract: An indicator mechanism for measurement instruments such as monometers or thermometers enables two display limits for switching processes to be independently set for an internal switching process. For example, the mechanism can be used to switch a compressor on and off in a defined relationship to the pressure. The actual value indicator is fixed on a rotating shaft between front and rear plates. The front plate carries a swivel arm acting with a desired value indicator, rotating about the actual value shaft, and carrying a microswitch. The swivel arm has one toothed section engaging the desired value shaft bevel gear and another driven by a bevel gear on an adjustment shaft. An additional similar rotating part with a microswitch is mounted on the front plate and drives a second demand value indicator. The adjustment shaft is coupled to the second toothed section of the additional swivel arm.

Title: Coil winding tap forming attachment - has wire pulling hook with spring bias connection to drive shaft and with stop near shaft coacting with shaft lug
Inventor: FELDSCHTEJN ISAAK JAKOVLEVITSC
IPC: H02K15/04
Filed: 1979-04-24
Abstract: The mechanism for forming tapping during coil winding contains a rotating hook, featuring a spring connection to its drive shaft (7). The design reduces the inertia of the mechanism masses and thus allows a faster operation of the winder to be carried out. The wire (2) is picked up by the hook (1) and drawn out of the winding zone. This is followed by its release for further coil forming. The shift of the hook controlled by cam (3), is made in relation to the wire guide (5), with the movement derived from a vertical shaft (12) and sprocket (13). The cam actuates a rod (16) articulated to the mechanism housing (8), which holds the hook unit. The hook has a strip (9) near the drive shaft, which cooperates with a lug (10), rigidly mounted on the shaft.

Title: Coupon filling aid - with square cut=outs in front of plastic foil sheath
Inventor: LIETH WOLFGANG
IPC: B43L13/20
Filed: 1979-04-28
Abstract: Forms which have to be filled out in crosses or similar markings in a repetitive way, like applications for tax rebates or football pool coupons must be marked only in certain small boxes. This applies partic. when a football pool coupon is filled out by the same standard permutation every week. This work is facilitated and mistakes such as crossover of two boxes, crossing too many boxes, etc. are eliminated by a template. This consists of two sheets of soft PVC, joined by welding along two sides, between which the coupon is inserted. The front contains the same number of purposely weakened squares which correspond to the number of squares on the coupon. The squares to be used in the weekly permutation are pressed out so that only they can be filled in.

Title: Continuous production of solar cells - by depositing small grain semiconductor material and recrystallisation
Inventor: DEMINET CZESLAW
IPC: H01L31/0368
Filed: 1979-04-30
Abstract: Solar cells are produced by forming a substrate, providing a first electrode on one surface of the substrate, depositing a layer of small grain semiconductor material, doped N or P, on the electrode and recrystallising the semiconductor material to increase its grain size to the point where the layer may be used as an active element in a solar cell, while simultaneously removing electrically conducting impurities from the material. The upper portion of the resulting layer is doped to form a PN junction in the layer and a second electrode is formed over the layer, in contact with the upper portion of the layer. Economical mfr. of large area silicon solar cells is provided. Use of a deposition process, rather than a slice and polish process, allows continuous production of large area configuration solar cells.

Title: Hydraulic feed mechanism for bar cutting machine - uses preheated hydraulic fluid to maintain constant viscosity
IPC: B23D25/04
Filed: 1979-07-06
Abstract: A machine for cutting long metal bars into shorter lengths has a hydraulically operated bar feeding mechanism which determines the length of the cut bar. Variations in temp. of the hydraulic fluid cause variations in the fluid viscosity which in turn cause errors in the length of the cut bar. This variation in viscosity is eliminated by heating the hydraulic fluid in the supply tank before passing it through the control valve (14) to the cylinder (2) which actuates the bar feed mechanism. When the cylinder (2) is not operating the fluid is circulated through the throttling orifice (12) and by-pass valve (13).
Patent DE-2927635-A1 (DE)
Title: Football boot with two running sole bending zones - has inserts dividing inner soles to improve flexibility and prevent distortion
Inventor: DASSLER ARMIN A
IPC: A43B5/02
Filed: 1979-07-09
Abstract: Cutouts at right angles to the long axis of a football boot, in the elastic polyamide surface layer of the running sole, extend across the bending zones and into the base structure of the sole. Where the cutouts pass through the reinforcing layer between the base structure and the surface layer, the base structure, at least in the zones of its edges, is thinned down. Where the inner sole is stamped out in line with the bending zones of the running sole, the inner sole is divided from one edge to the other. The base structure is bonded to the inner sole, and in each stamping a lens-shaped filling piece of material compressible in volume is glued transversely to the centre line. The elastic suppleness of the running sole in the bending zones is improved still further, so that the rolling motion of the foot meets very little resistance, whilst distortion and rucking of the inner sole, even with severe bending is avoided.
Patent DE-2929019-A1 (DE)
Title: Temp. measuring system for superconductors - converts specified temp. values of magnetic resistance temp. detector with simultaneous change of coil inductance
Inventor: BRANDELIK ALEXANDER DIPL ING D
IPC: G01K7/00
Filed: 1979-07-18
Abstract: The temp. measuring detector has a magnetic resistance which is very high in the superconductive range, i.e. below the critical temperature and the critical magnetic field strength, forming the change-over point. Above this point, i.e. in normally conductive range, it is very low. The temperature at the measuring point can thus cause a change-over from the superconductive into normal conductive range, or vice versa, with surge-like resistance changes. The variable resistance changes in the same manner as the magnetic resistance of a magnetic circuit of a coil, and the coil inductance, dependent on the measuring temperature at the change-over point. By adjustment of a preset magnetic field strength by the current fed to the coil, the position of the change-over point on the field strength/temperature curve can be adjusted, when a superconductor is used as the variable magnetic resistor.

Title: Permanent magnet based switched brake - creates eighteen kilo-gauss field using rotating ferrite magnets
Inventor: BAERMANN MAX
IPC: H02K49/04
Filed: 1979-09-20
Abstract: The braking system uses permanent magnets using eddy current effects and/or friction forces for railway vehicles and eddy current effects only for road vehicles. Part of the permanent magnet system is rotated through 90 deg. to give the braking effect by creating a flux density of 18kGauss in a 1mm air gap. This is achieved by using ferrite material including metallic oxides of barium strontium or lead. The brake consists of fixed magnets arranged alternately with the rotating magnets along the axis of the rail, the rotating magnets having pole pieces shaped to follow the air gap profile in the braking condition. The rotating magnet axis is perpendicular to the rail and is defined by a central cogged shaft through which they are rotated.

Title: Multilayer glass optical waveguide fibres - where outer sheath with low coefft. of thermal expansion provides fibres with high tensile strength
Inventor: KAO CHARLES KUEN
IPC: C03C13/00
Filed: 1979-09-29
Abstract: Fibre consists of a core (a); an outer layer (b), and a sheath (c), where the tensile strength of the fibre is increased due to the difference in the coefft. of thermal expansion (CTE) of layers (a, b). All the layer forming the fibre are deposited successively in the bore of a substrate glass tube, which is then collapsed to make a fibre blank; and the initial substrate glass is removed before drawing the blank into fibre. Materials (a, b) pref. have a high CTE and low glass transformation temp. (GTT), while the thin sheath (c) is quartz with low CTE and high GTT. The substrate is pref. removed to a prescribed depth by grinding, then cleaned, etched and polished to form the blank. One pref. sheath (c) is hard quartz, whereas the substrate contains 96-97% SiO2, the rest being B2O3 and Na2O. Sheath exerts high compressive stress e.g. over 345 N/mm2, so the fibre has a higher axial tensile strength and longer life than conventional fibres.
