Title: Clamping devices for castors on movable apparatus
IPC: B62B5/04
Filed: 1972-05-19
Abstract: 1331215 Castors HAPPE & CO 19 May 1972 [21 May 1971] 23649/72 Heading A4U [Also in Division F2] A clamping device, for castors 6 mounted on two adjacent tubular legs 1, 2, (e.g. of an invalid chair), connected by transverse means 3, comprises two holding means 14 each operative to hold a respective castor against motion, two elements 22 each reciprocable axially within a respective leg 1 or 2 and each biased axially by a spring, motion of the element in one direction effecting application of the associated holding means, and motion in the other direction effecting release, two link pins 25 each connected to a respective one of the elements 22 and extending through a longitudinally extending slot 26 in the wall of the associated leg, and a rod 28 manually operable to cause sliding of the link pins in the slots and thus cause movement of the elements in one of the directions, the rod having a position external of the connecting means 3 such that inadvertent motion of rod 28 is prevented by the connecting means. In Figs. 1 to 4, legs 1, 2 are connected by a transverse stay 3, each leg having within it a reciprocable element 22 having connected to it a link pin 25 extending through a slot 26. A rod 28 having two levers 29 is connected by crank webs 27 to the pins 25. In each leg a spring 23 urges, through the element 22, a bolt 13 downwards to tilt further a Z-shaped curved plate 14 from the Fig. 2 position. In Fig.2, pin 25 is held near the top of its slot by engagement of rod 28 at A and lever 29 at B, respectively, with a ring 30 surrounding the stay 3, past a dead-centre position. When lever 29 is moved upwards to the Fig. 3 position, spring 23 urges element 22 and bolt 13 downwards, so part 14'of plate 14 raises plate spring 16 so that its free end 16' engages toothed plate 21, preventing castor swivelling, and lowers plate spring 17 so that spring 17 brakes wheel 6. Stop pin 31 assists alignment of cross-bore 22' and pin 25 during assembly. In Figs.5 to 7, (not shown), spring 23 is below element 22 and acts upwards for release. Rod 28 is also below stay 3, and lever 29 is pivotted downwards to reach the release position: a radial plug (29") is provided at each end of rod 28 to engage stay 3 in the release position. In Fig. 9, spring 23 acts downwards to apply the brake; each lever 29 has a side member 33 formed integral with it, and to the side member is pivotted at 35 a semi-circular link 34 connected to pin 25. Each lever is itself pivotted about stay 3, so rod 28 describes an arc around the stay between positions. In the release position, Fig.8, (not shown), pivot 35 is located past the top-deadcentre position of link 34, so spring 23 maintains this position via element 22 and pin 25; the inside of link 24 engages stay 3. In Figs. 11 and 12. "rod" 28 actually surrounds stay 3 except at the ends (see Fig. 12) so that there the link 34 can contact the stay in the release positon.

IPC: H02P1/20
Filed: 1919-09-29
Abstract: 155,662. British Thomson - Houston Co., (General Electric Co.). Sept. 29, 1919. Master control systems. - Relates to systems comprising electro-magnetic contactors of lock-out type and a master controller giving two running positions. In order to reduce the current to an amount which can easily be carried by the master controller, the winding of the first contactor is connected across a resistance, the other contactors, if employed, being connected as usual. The diagram shows an arrangement of three notching-contactors 14, 15, 16, four reversing contactors 10, 11, 12, 13, and a master controller C for a commutating-pole motor A. The first forward or backward step of the master controller only affects the reversing-contactors. The apparatus may be left in this condition, the motor running with all resistance in circuit. If the controller is turned the second step, it switches in the first notching contactor 16, which is of the known lock-out type and has a relatively fine winding in parallel with a resistance section R. The automatic action which then takes place, provided that the current is within the proper limits, first puts the winding of contactor 15 across the ends of resistance R<2>, and then puts 14 and 15 across Rand R<2>, finally short-circuiting R' and leaving the motor in full running condition.

Patent GB-361346-A (GB)
Title: Improvements in processes for obtaining vegetable albumens
Filed: 1930-08-12
Abstract: Vegetable materials are peptinized by means of a saline solution, and the insoluble materials are separated by ordinary filtration.  The albumens are then flocculated by partial or total dialysis of the crystalloid substances through an ultrafiltering membrane of medium porosity, i.e. a membrane which will filter 300-1000 litres of water per square metre and per metre of water pressure in one day.  The flocculation may be hastened by agitation of the solution and the water, and may be completed by ultrafiltration, but at least 75 per cent of the salts should be eliminated in the dialysis.  Before the ultrafiltration, the coagulated albumen should be separated by centrifuging.  According to the example, oil-cakes, e.g. of earth nuts or soya, are ground, before or after complete de-oiling, and then 1 part by weight of oil-cake is mixed with 3 parts of cold or tepid 10 per cent salt solution.  After about 30 minutes, 7 parts of salt solution are slowly added, and the solids separated by filtration.  The residue is pressed, and may be dried and ground; it is suitable for use as a foodstuff for cattle, or for use in the manufacture of industrial dextrin, or in fermentation industries. The clarified liquor may be treated in a hyper-centrifuge to separate traces of light insoluble substances such as starch, and is then submitted to dialysis through an ultrafiltering membrane of medium porosity, such as collodion, cellulose or cellulose acetate.  The operation is facilitated by a double circulation in the dialysing apparatus, and by a slight pressure of the other of a few decimetres of water maintained on the liquor side to check endosmosis.  From 5 to 8 or more litres of liquor are treated per hour and per square metre of dialysing surface.  The salt water is concentrated for re-use, and the albuminous liquor is treated in a hyper-centrifuge. The product is dried, and the residual liquor is further treated by ultrafiltration, the material remaining on the membranes being added to the main body of albumen.ALSO:Oil cakes, such as those of earth nuts or soya, before or after complete de-oiling, are ground, and then worked up with a salt solution to peptinize the albumens. Insoluble matter is separated, e.g. in a centrifugal suction filter, and this residual moist oil cake is pressed and may then be dried and ground.  It is a slightly nitrogenized cattle food.
