Title: Electrically driven actuator - has spring loaded ram to control torque requirement during lifting and lowering
Inventor: DOELL JUSTIN
IPC: B66F3/08
Filed: 1974-12-18
Abstract: Electrically driven actuators demand high motor torque when lifting a load. During lowering, the load's potential energy is released and the motor is duly assisted. Torque varies widely. Torque range is reduced by a spring (7) which stores the energy of the load when lowering, and assists the motor when lifting. The spring force and the load equilibrate at mid-stroke of the ram and motor input is minimized. A spring (7) works between end (8) of the ram (1) and end (9) of screw (6). The axially fixed screw (6) is turned by motor (4) and operating ram nut (5). The arrangement can be modified whereby the nut is fixed and the screw moves axially.

Title: Powered garage door actuator mounted on door - has actuating belt connected to wall and programmed motor switches
Inventor: BRABANDT MARTIN
IPC: E05F15/681
Filed: 1975-05-21
Abstract: The power-driven mechanism for opening and closing a garage door is almost completely mounted on the door panel and can also be supported by the ceiling. The motor is powered by a low voltage and the low voltage supply unit can also be used as a motor vehicle battery charger. The vibrations of the drive are not transmitted to dwelling rooms above the garage because the drive is mounted on the door panel. A coupling is designed to overcome starting force, and for shock absorbing and overload protection. The hinged drive motor can be rotated out of engagement with the drive by a hand lever. This motor is coupled to the pulley (45) for driving the flat belt connected to the door panel (1).

Title: Thermoplastic resin compsn. for extrusion moulding - contg. fatty acid esters for improved resin props
Inventor: OHKAWA HIDEO
IPC: C08L1/00
Filed: 1975-07-17
Abstract: A compsn. for extrusion moulding comprises a formulation comprising 90-30% of a thermoplastic resin and 10-70% of an inorganic filler, whereby 0.1-5 pts. wt. of a sorbitan fatty acid ester or polyoxyethylene sorbitan fatty acid ester is added to the formulation per 100 pts. wt. of the formulation. Known formulations (1) deteriorate due to oxidation of resisn so that thread is undesirably cut (2) have poor stretching props. (3) uneven denier and (4) have difficulty in forming fine denier. Addition of the fatty acid esters eliminates these shortcomings. Resins available are polyethylene, PVC, nylons, PET, etc. Fillers are conventional CaCO3, CaSO4, talc, clay, etc. Fatty acid esters are sorbitan lauric-, oleic- and dioleic acid esters, or polyoxyethylene oleic-, dioleic- and palmitic acid esters.

Title: Belt filter with filter chamber and vacuum pump - with shut-off in case of tearing or end of paper
Inventor: MILLER PETER ANTHONY
IPC: B01D29/09
Filed: 1975-10-15
Abstract: Control system for terminating terminating filtration or filter cake drying, in an intermittently operating belt-type filter with chamber and vacuum pump connected from below, operates by measuring the throughput of the air or gas drawn into the filter chamber, and using it as a switching signal for the filter cake Drying or filtration. Pref. the appts. is switched off and a horn signal is sounded when the belt tears or is used up. The air throughput measuring device may be in the form of a conical glass tube in which is a suspended body, and the switching signal is caused by light barrier interruption by the suspended body. The degree of consumption of the filter belt may be measured by a co-rotating roller and connected counter which automatically shuts off the appts. and sounds the horn on not reaching a given number and after a given time.

Title: Circuit preventing bypassing of subscriber number blocking devices - is designed for PBX's with key dialling by multiple frequency system
Inventor: BARTEL ROLF
IPC: H04M3/38
Filed: 1976-01-30
Abstract: The telephone circuit prevents by-passing of subscriber number blocking devices in PBX's having key dialling using the multiple frequency system. When a connection is made to a local public exchange and a non-authorised number is dialled, the connection is broken. a multiple frequency key dialling receiver (MFV-E1) is provided in the PBX. It receives the a.f. frequencies transmitted to the local exchange, and retransmits to an evaluation device the recognised digits. It signals in addition when the effective duration of the key operation by the subscriber (T1n) is shorter than the min. duration which the key dialling receiver (MFV-E2) in the local exchange (OVST) can directly recognise.

Title: Foam generator for foaming liq. - has mating discs defining housing from which gas issues through joint between discs
Inventor: WITTERSHEIM ADAM
IPC: A45D27/10
Filed: 1976-04-01
Abstract: The generator comprises a pair of discs each connected with a housing with a gas inlet to one of the housings. One of the discs is recessed so that when the housings are connected together with the discs in mating relationship the discs define a hollow space. Gas supplied through the gas inlet enters the hollow space and exits between the discs in the form of streams for foaming a liq. Specifically the surfaces of the discs which come into contact are roughened so that a large no. of fine apertures exist when the two housings are connected. The degree of roughening defines the fineness of the gas streams generated. The generator is used in foaming liq. cosmetics.
