Title: Improvements in, or relating to, seats for use more especially as front seats of motor cars
IPC: B60N2/10
Filed: 1921-08-27
Abstract: 187,087. Austin, Sir H., and Challenor, R. Aug. 27, 1921. Sliding seats.-A sliding seat for a motor vehicle &c. is provided on its under surfaces with a guideway or guideways adapted to receive a member or members carried by a pair of supporting standards, so that when the seat is in its normal position its front edge is supported from the standards, and when the seat is moved forward to its full extent the standards form the supports for its rear edge. In the form shown the seat A is provided with two channels B, each comprising a forward half b parallel to the seat bottom, and a sloped rearward half b<1> connected to the seat by a web b<2> preferably integral with the channel. In the channels B run rollers c<2> mounted on pivot pins c<1> secured to the standards C, which are connected by a bar c. To brackets D secured beneath the seat are pivoted the rear ends of links d, which are connected by a bar d'. The forward ends of the links d are pivoted to links e, which are again pivoted to the standards C at e<1>, and are connected by a bar e<2>. The links d, e serve to keep the seat in alignment, and prevent the rollers becoming disengaged from the channels. Fig. 1 shows the seat in its normal position, whilst Fig. 4 shows it in its forward position, when the front of the seat is supported by the links d, e. The ends of the channels are closed to act as stops for the rollers c'.

Abstract: 723,275. Baling-presses. PORTABLE BALERS, Ltd. Sept. 11, 1953 [Sept. 16, 1952], No. 23193/52. Class 94 (1). A baling-machine has a press-box comprising fixed sides 14, 19 and a fourth side 37 formed by a mobile truck 13 which is adapted to support the material to be baled during the pressing and which is readily detachable to allow the pressed bale to be removed whilst still supported thereby. As shown the truck 13 is held in position where it forms the fourth side 37 by means of keyhole-slot connections 45 engaging the flattened ends of a rail 46 and by means of a plate 44 on the truck which engages over a guide 43 on the frame of the press. The press-head 29 is carried on a top 12 provided with wheels 21 permitting horizontal retraction along rails 17 when the press-head is in its uppermost position. Detents 23 operated by a handle 25 lock the retractable top in its working position.

Abstract: 773,629. Concrete mixers. AUGUST, P. Aug. 12, 1955, No. 23274/55. Class 86 A transportable concrete mixer consists of a trough 3 mounted in an inclined position on wheels 1 and having at its upper and lower ends respectively a discharge door 7 and means for charging weighed amounts of sand, cement and gravel. A water tank 29 with a spray-pipe 30 is supported above the upper trough portion. The materials are conveyed upwardly and mixed in the trough by a worm member 5 driven by a motor 6. The member 5 has a shaft 4 carrying an outer screw built up of spaced, tapered, helical blades 9 each carried on a radial arm 12, the outer edges of the blades being secured to a continuous helical strip 13. In the lower trough portion 5a, inner helical blades 10 are attached directly to the shaft 4 between the outer blades to form with the latter a continuous worm conveying the sand, &c., into the upper mixing portion 5b of the trough. In the latter a continuous helical blade 11 is mounted directly on the shaft to convey the material downwardly, i.e. against the conveyance direction of the outer blades 9, so that an intensive mixing effect is obtained. On completion of the mixing operation the door 7 is opened and the members 9, 13 effect the complete discharge of the material. The mixing time, about one minute, is such that by charging the trough at like intervals the mixer can be operated with a continuous discharge.

Title: Mechanical movements
IPC: F16K3/18
Filed: 1928-08-14
Abstract: 300,952. Karnath, K. Aug. 14, 1928. [A Specification was laid open to inspection under Sect. 91 of the Acts, Nov. 22, 1928]. Wedging or jamming. - A mechanical movement for sluice sliding valves &c. requiring successively a sliding and a jamming movement, comprises an inner spindle portion 3 and an outer screwed spindle portion 4 having at a certain stage a relative longitudinal movement which causes a rotary or jamming movement to the inner spindle, and at another stage a longitudinal movement in unison (in their most widely separated positions) for opening or closing the valve. In starting from the open position of the valve, shown in Fig. 1, rotation of the hand wheel and nut 27, 25 causes the whole movement to descend until the valves reaches the closing position, rotation of the inner spindle 3 and the rigidly-attached sleeve 10 being prevented by a roller 18 sliding in a vertical guide way 15, and rotation of the outer spindle being prevented by guide rollers 14, attached thereto, engaging the same guideway 15; the position referred to is shown in Fig. 2. On further rotation of the hand wheel the outer spindle 4 moves downwards, and the rollers 14 attached thereto traverse the helical slots 12' in the sleeve 10 rotating this sleeve and with it the inner spindle 3 causing cam members 6<1> to coact with lugs 7<1> to force the valve members 8 upon their seatings 9. For this purpose the roller 18 passes out of the bottom of the vertical guideway 15 into a horizontal slot portion in the manner of a bayonet fastening. Also a roller 23 which has passed through a gap 22 in a partition 20 is turned under the partition. In the reverse movement therefore of the hand wheel 27 to open the valve the first action of the rising outer spindle is to rotate the inner spindle, so that cams 6 can act upon arms 7 to release the valve members from their seatings, longitudinal movement of the inner spindle being prevented by the roller 23 until it reaches the gap 22. The whole movement is thereupon free to be lifted by further rotation of the hand wheel 27. The Specification further contains reference to a modification (not illustrated) in which the screwed outer spindle is replaced by a. rack in mesh with a pinion carrying an operating handle.

Filed: 1960-07-05
Abstract: 957,803. Transistor switching circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. July 5, 1960 [July 8, 1959], No. 23467/60. Heading H3T. Overloading of the switching transistor 9 of a relay switching circuit due to transients developed by the relay winding 6 when the current thereto is cut off is prevented by connecting a further transistor 14 in series with the transistor 6, the base electrode of this transistor being connected through a resistor 15 to the collector-voltage supply terminal. As applied to a carrier-wave-telephony system incoming negative-going signalling pulses are applied to the base electrode of transistor 9, which is normally cut off by the bias applied to its emitter electrode, to render the transistor conducting. Transistor 14 conducts simultaneously and relay 6 is energized. At the end of the pulse transistor 9 is cut off and its collector electrode instantaneously assumes the voltage at the base of transistor 14, i.e. the value of the supply voltage while any transient produced by the winding 6 and applied to transistor 14 is effectively reduced in value by the same amount. The effect of transients is further reduced by resistor 16 and capacitor 17.

Vinyl alcohol-crotonic acid copolymers are made by reacting a vinyl acetate-crotonic acid copolymer with an excess of a C 1  to C 4  alkanol in the presence of a base, soluble in the alkanol, the amount of such base being at least sufficient to substantially completely neutralize the free carboxyl groups and to catalyze the alcoholysis of the acetyl groups of the copolymer. The reaction may proceed at ambient temperature and yields the salt of the vinyl alcohol-crotonic acid copolymer which can be converted to the corresponding acid form by treatment with acid. The base may be sodium or potassium hydroxide or sodium or potassium methylate and the alkanol may be methanol or ethanol. The copolymers may be made into sheets or films as disclosed in Specification 863,228. The initial vinyl acetate-crotonic acid copolymer may be prepared by polymerization in aqueous suspension in the presence of benzoyl peroxide and partially hydrolysed polyvinyl acetate.
