Title: Laminated armature core mfr. - includes press-cutting steel strip to form comb-like bands having spaced teeth and notches along opposite edges
Inventor: KAWASAKI KENZO
IPC: H02K1/26
Filed: 1978-10-13
Abstract: A laminated armature core (2) for a small rotary electric machine is made by helically winding a comb-like band formed from metal strip and having notches (1d) at regular intervals along one edge and spaced teeth (1a) extending laterally to the other edge. When the band is wound, the notched edge defines a bore (2a) which is later made a press-fit on a shaft member and the teeth adopt a radial orientation. Axial slits (1b) in the end of the teeth permit the divided ends to be splayed after winding to form arcuate shoes. Pref. two identical comb-like bands are made from a single strip by alternately notching the opposed edges at regular intervals and cutting the strip along a zig-zag path such that the teeth of one band are complementary with the spaces (1c) between the teeth of the other band.

Title: Swimming pool roof section bearing surface - comprise strip linked pockets tiered inside hollow longitudinal girder
Inventor: VOELKLE WILLI
IPC: E04H3/16
Filed: 1978-11-03
Abstract: The assembly of bearing surfaces, provides support and accommodation for telescopically sliding, arched shell sections of a roofing unit over a swimming pool, with roller units at their sides. The surfaces are arranged one above the other in a hollow profile longitudinal girder. They are formed of pockets, open towards the sides of the shell sections. The pockets are interconnected by strips aligned at right angles, and their connection points are coupled to the outside of the girder by horizontally aligned strips. Thus, shell sections of equal size and arc length may be used, and there is no danger of wind lifting them off.
Patent DE-2905715-A1 (DE)
Inventor: JENKNER ERWIN
IPC: B27F5/12
Filed: 1979-02-15
Abstract: So that the linear travel of the cutting unit with the crank mechanism (5) and the advantages associated therewith of the sinusoidal working movement of the crank in its length of travel during a cutting operation can be increased without changing the eccentricity of the crank, it is proposed that the crank mechanism (5) be arranged so as to be horizontally displaceable as a complete unit in a guide support (4). It is thus possible to cut recesses for fittings with the cutting unit. <IMAGE>

Title: Linear DC drive motor system - has comb-like runner excited by armature winding controlled by forced commutation thyristors
Inventor: BATYREV RUSLAN IVANOVITSCH
IPC: H02K41/02
Filed: 1979-04-24
Abstract: The forced commutation of the thyristors feeding the windings of the linear d.c. motor ensures that the speed of the comb-like runner is proportional to the supply frequency. The circuit enhances the efficiency of the motor as well as improves the mechanical characteristic stiffness. The interaction between the armature and the commutator with blocks for each of the winding section controls the excitation of poles in the armature. The linear d.c. motor (1) is controlled by a commutator (2) and comprises an armature (3) with slots holding the winding (4) facing the pole switching runner (5). The design of the motor ensures that at any instant three winding sections between the poles of the runner and three sections facing a pole are available. The commutator has switching blocks (6) fired by a logic circuit (7) and each control channel includes an amplifier.

Abstract: PCT No. PCT/EP80/00049 Sec. 371 Date Feb. 20, 1981 Sec. 102(e) Date Feb. 20, 1981 PCT Filed Jul. 11, 1980 PCT Pub. No. WO81/00203 PCT Pub. Date Feb. 5, 1981.Process for the permanent deformation of hair, wherein the hair deforming agent as used, is prepared immediately before use, by commingling of two components. One component contains a hair keratin-reducing compound, while the other component consists of a minimum of one organic compound with activated multiple carbon-carbon bond or contains such compound. In given instances, inorganic redox catalysts are additionally contained. The ready-to-use deforming agent may, furthermore, contain redox indicators to allow determination of the usability of the hair keratin-reducing compound. By commingling the two components to a ready-to-use hair deforming agent, the keratin-reducing compound is gradually bonded by adduction to the unsaturated aliphatic compound and thus being rendered unusable for hair deformation. The concentration of the keratin-reducing compound can thus be reduced in the course of the period of application and be adapted to the gradually softening hair.

A hollow vertical cylinder (71-73) of any desired polygonal section is fitted above the combustion chamber grate (1), its diameter being large compared to the chimney connection. Inside it, at intervals in the vertical direction, are two sets of roughly horizontal interleaved guide plates (11a-d,12a-d). For most of their periphery there is a narrow gap between the plates and the cylinder walls, and for the remainder a wider one, the wider gaps being on alternate sides so as to form a zig-zag main path for the flue gases (Pf3-6). A central vertical shaker bar (14), movable up and down, is coupled to all the plates and actuated by an external lever (29).

Patent DE-3003560-A1 (DE)
Title: Gas or air dehumidifier - using compressor and heat exchanger for heat pump
Inventor: ENGELBRECHT HANS
IPC: B01D53/26
Filed: 1980-02-01
Abstract: A device for dehumidification of gas or air operates on the heat pump principle. A compressor passes the compressed air through the tubes of a heat exchanger and after expansion across a restrictor back in counterflow through the heat exchanger chamber. The condensate produced is discharged through a water trap. This prevents any possible leakage of ammonia. It retains all the advantages of the heat pump principle in a simplified and improved shape.

Title: Measurement system positioning servo controller - eliminates quantisation errors using control path model and output comparison with position
Inventor: MAGDANZ MICHAEL
IPC: G05B19/19
Filed: 1980-11-18
Abstract: The servo controller is for a measurement device and positions a measurement element in one degree of freedom. It uses a computer which produces program dependent demand value signals for a controller whose output signal drives a position motor. The motor positions a measurement element and an actual value transducer. The arrangement prevents quantization errors of the components from affecting positioning errors. The computer contains a model of the control path whose output is compared with that of the actual value transducer. The output of the comparison circuit is in the form of a difference signal which is used to correct the controller demand signal after being passed through an evaluation circuit. The correction system ensures zero error in the static condition.
