Title: Hot pressed resin impregnated fibrous material - is lacquered by applying lacquer sheet before pressing
Inventor: HOFFMANN KARL
IPC: D21H27/26
Filed: 1975-06-11
Abstract: A method of making coated or lacquered mouldings from fibrous materials containing water and impregnated with natural or synthetic resins, using heat and pressure, consists of applying the coating material as a hot-pressing lacquer sheet on to the still moist fibrous material and hot-pressing both together in one operation. The fibres are cellulose, wood, paper, wool, cotton, hair, synthetic fibres, glass, asbestos. The applied film is made from an aqueous dispersion or suspension of film-forming binding agent, optionally containing pigments, fillers and other additives. The fibre matrix is woven or non-woven, pressed or cut to shape or as sheets. By applying the coating as an already formed lacquer sheet, instead of as a fluid coating mixture a simplified and more economic process is obtained. The lacquer sheet has a weight of 40-400 (70-150)g/m2. After pressing, it thickness is 5-500 (30-120)micron. Two or more lacquer sheets, of the same or different colours, are applied simultaneously.

Title: High lift reciprocating submersible suction pump - is driven by linkage with vertical driving arm acting as pendulum
Inventor: JOURNEY WILLIAM KENNETH
IPC: F04B47/14
Filed: 1975-07-09
Abstract: Pump has a cylinder (1) containing a reciprocating piston which is on the end of a piston rod the upper end of which is pinned to a lever arm. This arm is bent at right angles with one half held in two bearings. As this half pivots on its own axis, the other half moves in a vertical plane and drives the piston rod up and down. A second lever rigidly attached to the horizontal section of the first lever hangs vertically down below it. This second lever carres a weight at its bottom and swings as a pendulum with the rotation of the upper lever. The pendulum weight balances the reciprocating weight of the piston statically and dynamically.

Title: HV source regulator with electron tube - has transistor base driven by signal depending upon difference between control grid voltage and constant reference
Inventor: DUTU DORU K A
IPC: G05F1/52
Filed: 1975-08-20
Abstract: High voltage source regulator has an electron tube (Q), a transistor (T1) and a variable resistor (R2) connected in series. The control grid of the tube is connected between the transistor (T1) and the variable resistor (R2). The transistor base (T1) is connected to a regulating amplifier which drives the base by means of a signal.

Title: Remote control for equipment in TV studios - has one channel operated in half:duplex mode using extra pulses to switch direction
Inventor: DUNKEL KARL-HEINZ
IPC: G08C19/16
Filed: 1975-11-04
Abstract: The remote control, for issuing instructions to equipment, such as crossbar couplers and tape recorders in television studios, uses only one or a few channels and contains signal converters in both the control console and the equipment. Both control console and equipment contain transceivers to allow signalling pulses to be transmitted alternately in both directions. The control console signal converter generates an auxiliary pulse which is transmitted to the equipment signal converter. The latter converter converts the pulses into signals that switch the equipment transceiver to transmit and the control console to receive.

Title: Telephone PBX's with central control - enables through calls to be dialled and signals to be converted and retransmitted with suitable delay
Inventor: SPRINGER NORBERT
IPC: H04Q3/00
Filed: 1976-08-06
Abstract: Through connections can be built up from an originating exchange of a calling extension through a transit exchange e.g. in case of an incoming external call through a main exchange to a target exchange of a called extension. Dialling signals are converted and retransmitted with a delay in a through dialling exchange. Reception and transmission of dialling signal is in parallel, and dialling end signal received in the target exchange is retransmitted to the originating exchange. The delay in dialling signals retransmission is greater than or equal to the width of a pulse plus an interval of the order of the pulse or a pause width, so that dialling end signal retransmitted after last pulse of last digit in the dialing signal suffers a delay not longer than a multiple of time delay in retransmission, plus the dialling evaluation time in the target exchange.
