Patent GB-707069-A (GB)
Title: Improvements in or relating to mechanism for transferring successive articles or batches of articles laterally from a moving conveyor
IPC: B65B21/04
Filed: 1951-04-18
Abstract: 707,069. Conveyers. UNITED DAIRIES, (LONDON), Ltd., and LUNN. F. M. April 18, 1952 [April 18, 1951], No. 9097/51. Class 78 (1) [Also in Group XVII] Mechanism for pushing successive batches of articles from a moving conveyer comprises two spaced parallel crank shafts each having a number of crank pins at different distances from its crank shaft axis and angularly displaced from one another, a number of parallel pusher bars each mounted on and extending between a crank pin on one crank shaft and a crank pin on the other crank shaft and means for oscillating or rotating these shafts wheraby the pusher bars successively act on the articles to transfer them from the conveyer. As strown, bottles passing in single file along a belt conveyer 20, which may pass 200 bottles per minute, e.g. from a bottle washing machine, are deflected from the conveyer by pusher means comprising three pusher bars 27, 28 and 23 each carried at opposite ends by crank pins forming part of a pair of crank assemblies which are rotated in unison. Thus each crank assembly comprises a crank 31 having a crank pin 32 on which is mounted an end of pusher bar 27 which pin 32 in turn carries a crank 33 having a crank pin 34 on which is mounted an end of pusher bar 28, which pin 34 in turn carries a crank 35 having a crank pin 36 on which is mounted an end of pusher bar 29. In order to transfer batches of bottles into rows between guides 23 extending above a series of parallel belts 21 arranged so that each row of bottles will be supported by the adjacent edges of two belts, the last of the guides 23 is extended to form a stop, and a star wheel 25 driven in synchronism with the conveyer 20 has a portion 136 adapted to force itself between two bottles in the stream at intervals to split it up into batches and to hold back the oncoming bottles whilst the pusher bars 27, 28 and 29 act an the bottles. Owing to the different angular spacing and radius of the crank pins 32, 34 and 36 the lower pusher bar 27 first engages the bottles at a slow speed, and the pusher bars 28, 29 successively engage the bottles at faster speeds, thereby reducing the impact of the pusher assembly on the batch of bottles. Cranks 31 and star wheel 25 are both suitably driven from the drive to belt 20. Specifications 707,067 and 707,068 are referred to.

IPC: A61G9/02
Filed: 1951-04-19
Abstract: 697,352. Sanitary appliances. SCHAERER AKT.-GES., M. April 19, 1951 [May 8, 1950], No. 9182/51. Class 26 An apparatus for emptying and cleaning excrement and like vessels comprises a closable casing having internal rinsing means, in which the cover of the casing is pedal-operated to close it against an opening force, and a holding device is provided within the casing and adapted to hold a range of different types and sizes of vessel. The holding device (see Fig. 8), comprises crossed members 12, 13 the latter carrying jaws 16 connected by links 18. The handle 14 is slidable in its own plane against spring 19 to open the jaws between which the vessel to be cleaned is placed. A stop 15 determines the end positions of the cross which is pivotable about the axis of handle 14 to empty the vessel. A weight is arranged on the left-hand end of the member 13 to retain the cross in the initial position. The pedal operation is shown in Fig. 10 in which the pedal 5 is fully up and the cover 4 is open. When the pedal is first depressed the link 21 lies with the pin joint to the left of the slot in member 23 and chain 26 hangs loose. After the cover has descended fully (and the chain is taut), further movement of the pedal causes the pin of link 21 to slide to the right of the slot in member 23. When link 22 pivoted to link 21 rotates clockwise to pull on chain 26, this then rises against weight 27, and in so doing turns wheel 28 to which the water valve is connected. The pedal is biased up and the cover 4 kept open by the weights 6.

Title: Improvements relating to the production of cation-exchange materials
IPC: B01J47/00
Filed: 1944-05-13
Abstract: A cation-exchange material is prepared by treating a material having exchangeable silver with barium hydroxide.  A silver exchange material preferably made by treating a sodium aluminium silicate with silver nitrate, is treated with a solution of barium hydroxide, preferably in sufficient quantity to render the distribution of the precipitated silver oxide in the material substantially uniform.  The resultant material, without being washed, may be dried at temperatures below 100 DEG C. until the moisture content is reduced to 7 per cent. or less, and may be used as such, or mixed with the untreated silver exchange material.  The product may be mixed with a substance, e.g., fuller's earth and compressed into briquettes.  The treatment of the silver exchange material with barium hydroxide may be effected by percolation or by passing the barium solution first upwards and then downwards through a column of the untreated material. Examples are given, and Specifications 576,969 and 576,971 are referred to, the latter in the Provisional Specification only. According to the Provisional Specification, the silver cation exchange material may, if desired, be dehydrated before it is treated with barium hydroxide.ALSO:Sea water and other saline liquids are rendered potable by treatment with cation-exchange materials having exchangeable silver and barium.  The material may be mixed with fullers earth so that it disintegrates in use after briquetting.  The cation-exchange material is prepared by treating a material having exchangeable silver with barium hydroxide (see Group III). Specifications 576,969 and 576,971 are referred to.

Filed: 1947-04-08
Abstract: 631,824. Thermal switches. DUPONT, R. April 8, 1947, No. 9322. Convention date, April 11, 1946. '[Class 38(v)] A thermally-tripped circuit-breaker has a slidably movable spring-urged contactcarrying member carried by a spring-urged pivoted -member which is released by the fusing of a fusible member or by the deflection of a bi-metallic strip. The pivoted member is in the form of an outer frame 13 having flanges 18, 19, and an inner frame 23 pivoted on the same spindle 11, and having arms 25, 26 engaging between the flanges 18, 19 ,in such a manner that a " lost-motion " connection is provided between frames 13, 23. The movable contactcarrying member 29 has arms 27, 28 and a bar 31 which are slidably engaged in the frame 23; springs 33 being fixed in tension between the bar 31 and the frame 23 so as to urge the contact-carrying member 29 outwards. The contacts 6, 7, 36, 37 are closed when the pivoted frame 13 is held down by a fusible element 15 which is retained by a hook 10. The fusing of this element releases the frame 13 and the contacts part with a wiping action. To reset the switch, a further fuse 15 is inserted through a slot in the cover 5 into a notch 43, and a knob 39, Fig. 4; is depressed to turn a stirrup member 40, Fig. 3, to engage a rod 30 caried by the arms 27, 28 of the contact-carrying member 29. This retracts the slidable contact member and depresses frames 13, 23 fully, when lugs 8, 9 push the fuse 15 over into a position beneath the hook 10. On releasing the knob 39 the springs 33 bring the contacts into abutting engagement and at the same time urge the stirrup 40 upwardly into the position shown in Fig. 3. This also releases the frame 13 which moves slightly upwards to grip the fuse element 15, the lost motion connection between frames 13, 23 permitting this final upward movement withoutaffecting the contacts. In Fig. 5, (not shown), a bi-metallic strip engaging the end of the frame 14, is substituted for the fuse and hook 10, Specifications 522,543 and 533,816 are referred to.
