Title: Safety guard for shoe manufacturing press - automatically switches off press when guard touches any obstacle and guard may be of transparent plastics
Inventor: FUNCK HERBERT DR ING
IPC: A43D25/07
Filed: 1975-01-28
Abstract: The guard (21) is used with power presses for holding the uppers and soles of shoes together during the glueing operation. The press (1) has two uprights (2) which support a cross beam carrying the actuating cylinder (19). The press bolster (12) is pivoted on a pin (9) in lugs (8) attached to the base (3). A guard (21) of transparent plastics is also mounted on the pin (9) and rests on the bolster (12). Should the guard (21) touch the hand or clothing of the press operator, it is lifted off the bolster (12) and actuates the switch (25) which cuts off the pressure supply to the cylinder (19). The switch (26) overrides the switch (25) when the guard (21) touches the base (3).

Title: Roll gap sensing system - ensures contactless measurement by electromechanical sensor halves fitted into gap
Inventor: MEYER FRIEDRICH-WILHELM
IPC: G01B7/14
Filed: 1975-07-11
Abstract: The measuring arrangement for sensing the gaps between a pair of rolls is used for sensing the actual value of the roll gap for regulating arrangement. The rolls are used for producing a material strip of certain thickness within close thickness tolerances. The contactless measuring system has two halves and it can be used for a very wide range of applications. The sensor halves are positioned by an adjusting arrangement. The sensors are arranged eccentrically relative to the rolling gap and they rest by means of a movable lever system on the rolling stand. The sensor halves project into the gap between the roll necks. The position of the one sensor half is determined by a second working roll relative to the bearing shell.

Title: Automatic soldering appts - applies predetermined amt of solder to ceramic chip capacitor contacts without affecting flatness of component side
Inventor: BRADEN DENVER
IPC: H01R43/02
Filed: 1975-07-12
Abstract: Soldering appts. includes a flat support plate made of solder rejecting metal onto which a component with contacts having flat surfaces can be loaded. A retaining mechanism positioned over the support supplies a bias force to the component towards the flat surface leaving the remaining portion of the contact exposed. A predetermined amt. of melted solder is applied to the exposed portion of the contacts whilst a sufficient force is maintained to prevent solder flowing between the flat surface of the contact and the support member. Thus the entire contact is covered with solder except for the flat surface. Used to apply additional solder to pretinned ends of ceramic chip capacitors. One surface of the component remains flat after soldering so that it will not roll off a carrying surface during automatic handling operations. More solder can be applied to the contacts than is possible with conventional solder dip bath techniques. It is not necessary to employ a special layer of solder-repellant material bonded to the component or to treat the lower surface with special solder repellant material which has to be removed later.

Title: Immersed electromotor for pump - has warm liquid in stator rotor gap displaced by cool liquid passing through channel through rotor
Inventor: KIRCHENMAYER GEORG DIPL ING DR
IPC: H02K9/19
Filed: 1975-08-22
Abstract: A pump motor has its rotor immersed in the pump liquid. The temperature of the liquid in the gap is reduced by passing it through a special channel, through the rotor. This channel (5) is open at both ends and extends radially from the centre of the hollow shaft through the rotor to the gap between rotor and stator. Cooler liquid at the centre of the rotor therefore travels outwards to displace the warmer liquid in the gap. The temperature of the liquid drops and the motor can bear a heavier load. The channel can widen out at the gap end.

Title: Hydrogen halide removal from air mixts. contg. chlorine - by absorption in liq. contg. alcohol pref. glycerol
Inventor: LUEBKE DIRK
IPC: B01D53/68
Filed: 1975-08-27
Abstract: Air mixts. contg. Cl2 and hydrogen halides (I) is passed through a liq. absorbent contg. an alcohol, pref. glycerol, at standard temps. Selective absorption of halides (I) allows determination of Cl2 concn. in air in the presence of hydrogen halides, by using Ag2CrO4-impregnated paper as indicator (as described in parent patent). Cpds. (I) are absorbed completely. Cl2 can pass through absorbent down to 10 ppm vol. proportion in air. The reaction prod., (II) of absorbed hydrogen halide and alcohol absorbs no Cl2 and is non-volatile. The alcohol used has low vapour press. and is itself water soluble as well as its mixt. with (II). Both react neutrally and cause no corrosion.

Title: Small diameter rotating tool with indexable insert - has doubly tapered clamping wedges with clamping bolts with cylindrical nut
Inventor: REINHARDT HERMANN
IPC: B23C5/22
Filed: 1975-09-12
Abstract: The rotating small diameter cutting tools are provided with clamped indexable cutting inserts. These tools are especially solid and shell milling cutters as well as counter-sinking, boring and reaming cutters. The conventional wedge clamping method for indexable cutting inserts is improved to ensure good clamping effect of the clamping wedge and its holding in the cutter head. In addition to the taper in the clamping direction, the clamping wedge (5) is tapered also at right angles to this direction. A wedge hence also tapers in the circumferential direction of the cutter head (1). This wedge matches the seat in the cutter head and a clamping screw (14) of the inserts (9) is held in a tapped transverse bore with a cylindrical clamping nut.

Title: Winding station yarn guide - has a separate mechanism to secure yarn end and then retract for winding to proceed
Inventor: YASUOKA IKUMI
IPC: D01H1/38
Filed: 1975-10-23
Abstract: An appts. is claimed for winding yarns on to a bobbin sleeve, to secure the end of the yarn at the start of a winding phase, with an auxiliary drive and yarn guide working outside the range of the normal reciprocating cross-movement of the yarn guide during winding. The end of the yarn is brought to the surface of the bobbin sleeve to be inserted in the trap, and then moved along the axis of the winding shaft to be caught and wound, when the mechanism for the yarn end guidance is retracted to the rest position. The system ensures that the winding station can operate at the high speeds required, in the order of 2000-5000 m/min, in winding spun synthetic filament material.

Title: Small duty cycle current limiter - has logic circuit delaying start signal for next cycle according to load current integral valve
Inventor: WALTER DIETER DIPL PHYS
IPC: G05F1/455
Filed: 1976-02-12
Abstract: A current limiting circuit using an intermittent operating method with small duty cycle, in partic. an impulse operating method with phase control, is designed so that the time interval between successive pulse groups is large w.r.t. the duration of the pulse groups. In each operating cycle the current in the load is integrated and compared with a defined max. value. The current-time integral is retained after the on cycle. A logic circuit is used to delay the start signal for the next on cycle according to the integral value. After the comparator detects an integral greater than the threshold level the start signal delay is regenerated from one interval to the next in steps.

Title: Appts. increasing depth of field of microscope - oscillates barrel for insertion of rapidly changing optical elements of differing refractive indices
Inventor: WULLSTEIN HORST L PROF DR MED
IPC: G02B21/00
Filed: 1977-07-14
Abstract: The amplitude of the oscillatory movement which is described by the microscope barrel corresponds to the required increase of the depth of field. Its frequency is adapted to the frequency conventional for cinema projectors so that the user, e.g. surgeon is unaware of change of optical elements. The latter of differing refractive indices, are subjected to oscillatory movement by a special drive. A rotating diaphragm may be installed in the beam path of the microscope. The drive of the diaphragm is synchronised with the oscillatory drive. The amplitude of oscillation, the amount of increase in the depth of focus and the oscillatory frequency may all be adjustable.
