Title: Car seat with air sprung seat frame - has lost motion link operating air outlet and inlet valves to spring to maintain constant seat height
IPC: B60N2/50
Filed: 1978-11-16
Abstract: The sprung car seat comprises a frame carrying the seat cushion which is supported on a bottom frame via pivoted links (11) and an air spring. The seat level is kept constant irrespective of the wt. of the occupant by a valve assembly (23) which vents air from, or admits compressed air to, the spring as the seat moves above and below its selected level respectively. The valve operating mechanism (22, 28, 29) contains a lost-motion (x) link (24, 25) so that it maintains its position after it has opened one or the other valve (28, 29) and its movement lags behind the oscillating motion of the seat.

Title: Electronic temp. control for motor cars - with air flaps controlled by comparing thermistor readings and setting
Inventor: BEUTER RICHARD
IPC: B60H1/00
Filed: 1979-02-03
Abstract: The air temperature inside the passenger compartment of a motor vehicle is preselected by a potentiometer. The air control flaps which pass fresh air heated by a heat exchanger into the vehicles are adjusted by an electronic controller through a gear box until the thermistor for the inside temperature and the thermistor for the air mixture (fresh air plus air heated by the heat exchanger) confirm that the desired temp. exists. This compensates, for example, ambient changes within one second and saves any manual readjustment.

Title: Explosion cladding plant - where electronic circuits synchronise dosing of explosive gas mixt. and cladding powder into explosion chamber, and trigger igniter plug
Inventor: ZVEREV ANATOLIJ IVANOVITSCH
IPC: B23K20/08
Filed: 1979-03-07
Abstract: Plant includes a tubular-explosion chamber contg. an igniter plug, and an inlet pipe for cladding powder supplied by a doser fitted with a powder hopper. An inlet pipe is used to feed a carrier gas into the doser, and thus to carry the powder into the explosion chamber; a pressure controller regulates the amt. of carrier gas fed into the doser. A mixer is used to feed an explosive gas mixt. into the chamber. Electronic controller receives signals from a transmitting sensor, located on the open end of the chamber and indicating the presence of the cladding powder in the chamber. Controller then actuates a drive shaft fitted with a row of cams operating switches on the pipes feeding gases into the mixer to produce gas, and also controlling the igniter plug and the doser. The result is an automatic process.

Title: Glass melting furnace - where hearth is formed by metal pipes through which coolant flows, so solidified crust of glass separates melt from pipes
Inventor: GUSEV STANISLAV ALEKSANDROVITS
IPC: C03B5/44
Filed: 1979-03-29

Title: Enlarging bores of thick walled tubular articles - by mandrel composed of profiled collar mounted on tapered shaft
Inventor: ROZENBERG ALEKSANDR MINEEVITSC
IPC: B23P9/02
Filed: 1979-06-25
Abstract: The bore of a thick walled tubular article can be enlarged, by means of a special mandrel, with a very high degree of accuracy. The mandrel is built up from a shaft (2) with a tapered extension (5). A collar (1) of special longitudinal contour is mounted on the tapered extension and clamped by a threaded end fitting (3). The collar (1) expands the bore of the tube as it is pulled through with the mandrel. Because it has been forced onto the tapered shaft (5) a radial pressure is created between collar and shaft which prevents deformation of the collar (1).

Title: Filament texturising control - using tension measurement as indication of parameter variation to give continuous correction
Inventor: DAMMANN PETER DIPL ING
IPC: D02G1/12
Filed: 1979-08-21
Abstract: The tension of the continuous filament material is constantly measured through all the stages of the texturising process, including winding. These tension measurements are compared with reference values. If there is a deviation, then the tension or other parameter is corrected to bring it into line with the corresponding reference value for the process stage in question. The process gives a constant and continuous control of the texturising process, for continuous thermoplastic filament material.

Title: Tracking synchronisation for record disc replay - extracts recorded synchronisation information for comparison with intrinsic signal synchronisation by using interlock circuits
Inventor: IMANAKA RYOICHI
IPC: G11B27/36
Filed: 1980-02-15
Abstract: The equipment is for tracking the spiral information carrier, e.g. groove, on a flat disc by mechanical, optical or other means. The equipment controls the drive to prevent replay of the same track twice or jumping a track, thus missing information. The signal picked up from the track is checked by a regular signal also picked up and used as a synchronisation control. If the signal being replayed from the disc is video, the address signal can be located in flyback periods. The disc (1) is rotated on a turntable (2) with a motor drive (3). The pick up unit (4) feeds signal to the demodulator (5) and the address signal is picked out of the demodulated signal (a) and fed to interlock circuits (8, 9) where it is compared with the picture synchronisation signals (c, d). A signal monitor condition (i) appears at the output of a gate (12).
