Title: Semi-automatic buttoning-up machine for clothing factories - has several hooks engaging simultaneously round row of buttons and holes
Inventor: RAIMEL ENGELBERT
IPC: D06F89/02
Filed: 1974-03-16
Abstract: The buttoning device comprises a guide rail which has several hooks arranged at intervals corresponding to the button holes and is designed to move up and down on a guide rod. When the guide rail is moved down the hooks engage through the button holes and then through corresponding holes in a locally fixed contact support plate. The buttons on the shirt or the like are then hooked manually round the ends of the hook and the guide rail is raised drawing the buttons up through the holes into the closed position. An auxiliary holding rail with projections is designed to hold the button hole strip on the contact plate so that the buttons canpass up completely through the holes.

Title: Solids septd from liq phase by heat transmission - through membrane wall vibrated by foaming liq to keep free of deposits
Inventor: KOMAROMY ZSIGMOND DIPL ING DR
IPC: B01D9/00
Filed: 1974-03-26
Abstract: A thin membrane, rectangular or circular in shape, separates a liq. from which a solid is to be deposited from the heat transmission fluid. The heat transmission fluid, usually on the outside of the membrane, is foamed by blowing air through it so that it causes the membrane to vibrate. Any crystals or solids thus deposited on the membrane from the liq. state are shaken free keeping the heat transfer surface clean. Supplementary heating or cooling coils canbe incorporated around the membrane. The membrane is used for the concn of fruit juices, sugar solns, milk and NaCl solns. Maintains a clean heat transfer surface giving higher heat transfer coefficients and removing necessity to clean periodically.

Title: Roll unwinding machine anti-creasing system - runs strips at constant angle round front roll in line
Inventor: OHI TADAO
IPC: B65H19/10
Filed: 1974-06-07
Abstract: The strips of paper are fed off a number of rolls arranged in lines one behind the other, the lines being situated vertically one above the other, to common cutting mechanism. The strips from each of the rolls in one line (a, a', 1, 1') are led straight over the roll in front, except in the case of the front roll in the line, and to a roller (2) on a fixed mounting. Between this roller and the front roll in each line is a movable roller (3, 3'), adjusted downwards as the roll diameter decreases. Thus creasing is avoided and the angle at which the strip passes round the front roll is kept constant. The movable rollers can run in bearings (5) sliding in guides (4, 4') inclined in front of the lines of rolls.

Pref. (I) is derived from an acid of formula HOOC-R1-A-R2-COOH or HOOC-R3-N-R4-W and (II) has formula Co(X)m(Y)n Zp (in which A is a hydrocarbyl gp., =O, =S or =NR6; R1-6 are opt. substd. hydrocarbyl gps. and R6 can also be H; W is a COOH or hydroxyalkyl gp; X is NH3 or an organic mol. contg.

Title: Niobium electroplating of copper tubes - passed through niobium contg. electrolyte inside electric resistance furnace
Inventor: DIEPERS HEINRICH DR
IPC: H01L39/24
Filed: 1974-09-27
Abstract: A tubular conductor for superconductive cables, consisting of a niobium layer and a copper layer, is produced by passing a copper tube under inert gas continuously through a chamber containing a fused electrolyte with biobium. A pump keeps the electrolyte level above the tube and its entering/leaving ports. A potential applied between the tube and an anode immersed in the electrolyte produced a plated deposit of biobium on the tube. This produces satisfactory niobium coatings on long lengths requires for cables. It saves drawing operations which reduce the section and the wall thickness and results in a seamless coating.

Title: Continuous manufacture of flat separated insulation conductors - using a machine which deposits an insulating layer on each side of a parallel conductor set
Inventor: HERRGOTTSHOEFER MANFRED
IPC: H01B7/08
Filed: 1974-11-14
Abstract: A system for the continuous manufacture of a set of parallel insulated flat conductors is presented. The conductors form an insulated broad flat band, inside which they are insulated from each other only by the separation between them. Basically, the machine consists of two roller (3, 4) between which the parallel set of flat copper conductors (1) is continuously fed. Two layers of polyester or polymide insulating tape (7, 8) are fed on to the rollers so that they stick to the conductors under the roller pressure and the whole flat band emerges in the form required. Short conducting sets are made in precisely this way continuously whilst for longer sets, additional stiffening separating strips (8, 10) are interposed between the conductors and insulator, at right angles and at regular intervals.

Title: Elastic spoiler for front of car - is resilient to alter angle with wind force and with elastic stop for obstructions
Inventor: FIALA ERNST PROF DR
IPC: B62D35/00
Filed: 1975-11-05
Abstract: The front spoiler is made from a single elastic moulding complete with a mounting strip (4) and spoiler blade (2). The angle of the blade is altered with the wind resistance as the speed increases. An elastic stop (3) behind the spoiler limits the amount of wind deflection. If the spoiler strikes an obstruction then the elastic stop has sufficient give to allow the blade to slide over the obstruction without damage, and return to its original setting. The multi angle spoiler provides optimum stability over a wide range of speeds. The spoiler blade hinge section (6) is weaker than that of the elastic stop.
