Title: Petrol recovery from petrol air mixtures - by saturation, compression, liquefaction and scrubbing with absorbent solution
Inventor: FREY GERHARD DIPL ING
IPC: B01D53/14
Filed: 1973-05-18

Title: Spreader for powdered or granular material - has container with at least one outlet, with flap and fertilizer conveyor-belt floor
Inventor: ECKERT KARL-HEINZ
IPC: A01D90/12
Filed: 1973-11-03

Title: Gas flow control valve - is governed by pressure variation in sensor chamber opening membrane on valve plunger
Inventor: KYFFIN-HUGHES JOHN MALCOLM
IPC: G05D7/01
Filed: 1973-12-18
Abstract: A membrane operated tapered valve plunger controls the gas flow through-the regulator valve. The membrane is deflected by pressure variations in the sensor chamber, thus responding to one or several parameters. An adjustable compression spring which acts on the membrane is used to calibrate the valve. A solenoid plunger pushes the valve taper into its seat when the valve is switched off, thus interrupting any gas flow. The solenoid mechanism is situated on the opposite side of the valve housing to the membrane and its spring.

Title: Sheath for the active mass in a lead accumulator - made by sintering plastic powder to form a porous tubular basket
Inventor: METZLER OTTO
IPC: H01M50/474
Filed: 1974-01-24
Abstract: This is an addn. to 2048796 which described the mfr. of a sheath for the active mass in a lead accumulator, made from an oxygen- and acid- resistant plastic granulate with an extremely small grain size, where the plastic granulate was hot- or cold-sintered in dies to an open, micro-porous ske-framework of the desired shape. In the present invention, for hot sintering a die is used made of a material with good thermal conductivity which is heated to the sintering temp. and brought into contact with the plastic; for cold sintering a die is sprayed with a liq. which dissolves the plastic, after which the plastic is spread on the die to the required thickness and dried. At least the inner wall of the sheat is pref. coated with an ion conductor viz. lignin sulphonate or colloidal graphite. A mechanically strong, porous sheat is thus inexpensively mfrd.

Title: Seal for rotary piston engine - having edge or face hardened by nitriding or desulphurisation
Inventor: NARIKAWA SATOSHI
IPC: F01C19/00
Filed: 1974-02-11
Abstract: The seal is formed from a rectangular cross-section ring blank which is coated upon all sides by a plating of Cu, Ni and/or Cr. The plating is removed by polishing or grinding from the face or edge which it is desired to harden. A nitriding or desulphurization treatment is then effected on the blank, hardening only the uncoated areas. The blank is then machined to cut a groove about the ring blank and to slope the leading face. The remaining coating can opt. be removed by polishing or burnishing.

The lengthways crease or channel along the middle of the flat shaped-sections, of which the frame is made up, is pref. of round cross-section; the amount of material used is slight, but the sections are rigid and permit the use of light concrete, plastic or other materials with low load-bearing capacity in the prefabricated building components. The lengthways creases in two abutting flat sections may be interlocked in tongue-and-groove fashion, or combine to form a tubular cross-section. There may be connecting media at right angles to the flat sections.

Title: Control for centrifugal moistening unit on rotary offset printer - ensures that quantity of moistening liquid applied is related to speed of printing machine
Inventor: STEGMUELLER ALBERT
IPC: B41F33/00
Filed: 1974-03-19
Abstract: A comparator circuit forms a differential voltage between that voltage proportional to the rated value of the cylinder speed and that voltage emanating from an actual-value transmitter. At least two relays controlled by the differential voltage have a working contact for the forward and backward rotation of the servomotors. An amplifier is placed in series with the rotary speed counter. The rated value voltage can, using a manually adjustable resistance, be matched relative to the object to be printed. The actual-value transmitter can be adjusted by a movable valve part which determines the rate of the throughput. Each set of moistening rollers has its own valve and each valve has its own servomotor.

Title: Continuously filling and sealing plastic bags - with successive pairs of drive belts and separate welders
Inventor: WUESTEFELD HANS
IPC: B65B43/52
Filed: 1974-05-09
Abstract: Filled and sealed bags of thin plastic film are produced continuously by dividing a longitudinally folded film web into bags by lateral weld seams which run from the folding edge to a distance from the open edge. the web is fed stepwise by belts gripping it vertically on both sides, it is filled and sealed using one pair of the belts at the filling point and one subsequent pair at the sealing point. The latter belts are lower than the former and have a guide roller on the shaft of each drive roller at the feed-in end, the top edge of each such guide roller is level with the top of the belt at the filling point; the film web being gripped by these guide rollers. A space between filling and sealing points is thus avoided.

Title: Automatic level control for tape recorder - has switch applying voltage to capacitor which controls amplifier gain via regulator
Inventor: GEHRKE HERBERT
IPC: H03G3/30
Filed: 1974-08-23
Abstract: The automatic level control, for a tape recorder, has an amplifier whose rectified output signals charge a capacitor shunted by a discharge resistor. The amplifier gain is controlled by a regulator according to the d.c. voltage a across this capacitor. The gain is controlled selectively by an additional voltage which is built up by applying a fixed d.c. voltage (+UB) via a switch (9) and resistor (8) to a capacitor (6) and decays by opening the switch. The switch and RC circuit are located between the input to the regulator and the output of the LF equalising amplifier.

Title: Switching mechanism for protective cct. breaker - has pivoted spring-loaded contact arm linked over latch to pivoted operating arm
Inventor: KAMMER GUENTHER
IPC: H01H71/52
Filed: 1974-11-26
Abstract: The switching mechanism has its contact arm (5) pivoted at its centre on a pin and spring-loaded (7) at its upper part. In the ON position the lower end of the contact arm touches a lower fixed contact (11) and in the OFF position the upper end touches an upper fixed contact (8). The operating lever (1) is linked to a locking device (3) and from the locking device to the contact arm centre pin. The contact arm pin and the locking device pin (9) move along separate slots (10, 6) when the switch is operated. The locking device holds the contact arm in its ON position against the action of the spring. When the operating lever is released, i.e. pivoted to the right, the locking mechanism drops and the spring pulls the contact arm away from the lower contact.

Title: Electronic time storage relay - has timing value of generated output signal equal to that of input signal up to max storage value
Inventor: TESCH KLAUS
IPC: H03K17/292
Filed: 1974-12-02
Abstract: The electronic time storage relay has a delayed release and a preset time storage value. Until the maximum time storage value is reached, duration of the output signal generated by the current pulse relay (4) is constant and equal to that of the input signal at terminals (2, 3). Capacitors (5, 6) are charged by a voltage from a resistive voltage divider (7-9) through diodes (10, 11). After that a further, timing charge of the capacitor (6) is carried out through a control resistor (13) in accordance with the input signal duration. When the input signal abruptly ends, this charge is dissipated with a time delay through a diode (14) and resistors (15, 16).

Title: Three phase watt hour meter - converts result to metering pulse train via switches on voltage and current transformer secondary sides
Inventor: WATANABE KAZUMI
IPC: G01R21/133
Filed: 1975-06-03
Abstract: An electronic watt-hour meter for a four wire three chase system is of simplified construction, giving accurate measurements with a readily obtainable as pulse. For each phase a voltage transformer (PT1,2,3) and current transformer (CT1,2,3) are provided to obtain stepped-down values. Three electronic switches (S1,2,3) for voltage and three for current (S'1,2,3) on the secondary sides are controlled by three phase control pulses to a working circuit (M) which multiplies voltage and current of each phase in turn and generates a current proportional to the sum of the electrical power of the three phases. This current is converted to a pulse train in a converter (A) and fed to an indicating pulse counter (F).
