IPC: H03F3/68
Filed: 1969-12-17
Abstract: 1282645 Television distribution system FERNSEH GmbH 9 Dec 1970 [17 Dec 1969] 61390/69 Heading H4R A co-ordinate switch for -video signals allows any input conductor to be connected to any output conductor and has at each crossing point an amplifier for connecting the respective input and output conductors which amplifier comprises a buffer amplifier and switching amplifier serially connected where the gain of each switching amplifier can be varied from zero to a predetermined maximum to effect the connection. The two amplifiers may be included in a single integrated circuit or may consist of miniature component amplifiers. As shown, the inputs E 1 -E n  are connected to individual amplifiers EV 1 -EV n  and outputs A 1 -A m  are connected to output amplifiers AV 1 -AV m . At each of the crosspoints where the input and output conductors can be selectively connected an amplifier assembly consisting of buffer amplifiers T 1 -T n , which have a constant high input impedance in series with switching amplifiers SV 1 -SV n  which have control voltage terminals 1-n to which a voltage is applied to vary the gain of the respective switching amplifier. The amplifiers have a high output impedance when the gain is zero and a low output impedance at other gains. The amplifiers are preferably feedback amplifiers and have a substantially linear relationship between the input and output voltages. In the practical embodiment, Fig. 2 (not shown), all the amplifiers corresponding to a column are mounted on a plate which is secured adjacent the other column plates on abase-plate.

Patent GB-944342-A (GB)
Title: Improvements in processes for the purification of crystallized substances
IPC: B01D9/00
Filed: 1960-05-02
Abstract: Impure paraxylene crystals are purified to remove other isomers &c. by washing them with warmer liquid paraxylene or a liquid paraxylene solution having a concentration higher than that of the mother liquor while they are at a temperature substantially higher than crystallization temperature but lower than ambient temperature, e.g. 0 DEG  to -10 DEG  C. on a vacuum filter surface.  The liquid is allowed to cool and partly crystallize in contact with the crystals on the same or another filter and the enriched and enlarged crystals are then separated from the liquid.  The process may be worked as a multistage recycle process.  Specification 944,343 is referred to.ALSO:Impure crystals which are being washed with highly purified and concentrated solutions or melted pure crystals are cooled in contact with the liquid so that occluded impurities are replaced by fresh crystallized material from the washing liquid. Specification 944,343 is referred to.

Title: Brake control valve mechanism
IPC: B60T13/22
Filed: 1978-08-16
Abstract: The braking system for an agricultural-type tractor and trailer includes a valve mechanism for alternatively controlling the fluid pressure in spring brake actuators fitted to the trailer in accordance with tractor braking effort and regulating the output from a pump (32) for releasing the spring brakes.

Title: Bar Stock Feeding in Multi- Spindle Lathes
IPC: B23B13/02
Filed: 1979-01-29
Abstract: In a combination of a multiple- spindle automatic lathe and a multiple-spindle bar material loading magazine, a device for feeding the bar material 16 from the magazine to the spindles 8 of the lathe comprises a feed block mounted in the lathe for reciprocating movement parallel to the axes of the lathe spindles 8, and a feed carriage 12a mounted in the loading magazine and adapted to cooperate with bar material carrying slides 1 of the loading magazine. The feed carriage 12a is operatively connected to the feed block via a coupling linkage 11, for synchronous of movement with the feed block. The linkage 11 cooperates with a pneumatic cylinder 13a mounted on the carriage 12a and acting as a link member between the coupling linkage 11 and the feed carriage 12a during the entire machining time of the bar material 16 in the lathe. The pneumatic cylinder 13a has a piston rod 13'a which extends through the cylinder 13a.

Patent GB-2069628-A (GB)
Title: Angular contact rolling bearing cage
IPC: F16C33/46
Filed: 1980-12-16
Abstract: A cage particularly for a tapered roller bearing comprises a large end ring 2 and a small end ring 1 both of plastics material joined by integral connecting bars 3, also of plastics material, which define pockets for receiving the bearing rollers. The bars are shaped to define a groove 6 which extends axially along the inner face. The various grooves 6 are commoned in an annular trough 4 into which lubricant may be supplied. During use, lubricant passes from the trough 4 along the grooves 6 from right to left by centrifugal force, thus leading to an improved distribution of lubricant within the bearing. In practice the assembly will require reinforcement if it is to withstand the high centrifugal forces encountered during use. One way of achieving such reinforcement is to make the assembly a snap fit within a conventional metal cage. <IMAGE>
