Abstract: 752,417. Resilient mountings; road-vehicle spring-suspensions. DAIMLER-BENZ AKT.- GES. July 19, 1954 [Aug. 1, 1953], No. 20996/54. Classes 108 (2) and 108 (3). In a resilient mounting comprising an inner part 20 extending through and beyond an outer part 25, and an interposed rubber sleeve 23 having an end portion 32 extending beyond the end of the outer part 25 for engagement with an abutment surface 33 on the inner part 20, a clamping ring 38 is applied around the free end portion and is adjustable for radial constriction of the latter. As shown, applied to a vehicle spring suspension, the ring 38 is a split ring clamped tightly by a bolt and nut (Fig. 3, not shown). The surface 33 is on a part 18 which also carries bearings for an upper wishbone link 14 and an abutment 22 for a suspension spring 21. The part 18 is keyed at 18<SP>1</SP> to the part 20, and is tightened down on to the sleeve end-portion 38 by a nut 1811. The part 25 is rigid with a frame cross member 37. A second resilient sleeve 24 is disposed in the other end of the part 25, and the two sleeves 23, 24 are spaced apart by a distance sleeve 29 and rings 27, 28. The flange 34 of the sleeve 24 may also have a clamping ring 38. The lower wishbone link 15 is pivoted at 17 to an extension 19 of the part 20. The extension 20 is anchored to the frame member 37.

Title: Refrigerating apparatus
IPC: F25B17/00
Filed: 1920-07-12
Abstract: 149,249. Czieslik, F. H., (Assignee of Howell, E. W.). April 17, 1915, [Convention date]. Ball and float valves are provided in an ammonia absorption refrigerating- apparatus working on the reversing system for automatically controlling the supply of fuel to the burner which heats the generator-absorber, the supply of water to the condenser and the water supply which effects the intermittent opening and closing of the expansion valve. The operations of the burner 6 for heating the ammonical-liquor and the expansion valve 22 are controlled alternately by a valve 30 which is automatically operated by means of a water supply from a conduit 35. The valve 30 comprises a casing 36, Fig, 3, and a rotatable cylindrical plug 37 with passages 41, 42, 43 therein and so arranged that when the passage 41 is in communication with the pipes 28, 28<1> which supply water to a vessel 23 which controls the movements of the expansion valve 22 the passages 42, 43 are closed to the water supply pipes 10, 10' for the condenser 4 and the gas supply pipes 44, 45 for the burner respectively. The valve 30 is adjusted in one or other of these positions the movements imparted to a float 31 in a vessel 32, the float 31 being attached by means of a link 40 having a pin and slot connexion to a lever 39 on the spindle 38 of the valve. The vessel 32 is adapted to be filled by the continuous supply of water from the conduit 35 through the pipe 33 and regulating-valve 46, and is emptied by means of the syphon 34 once in twenty-four hours; the connexions between the float and valve are in the arrangement described so adjusted that during twenty-two hours the passage 41 is open to admit the supply of water to the vessel 23 and for the remaining two hours communication is established for the supply of water to the tank 5 and gas to the burner 6. The vessel 23 and the supply of water thereto are so regulated that it takes a half-hour for the vessel to fill while the discharge through the syphon 29 is more rapid in order that the expansion valve 22, which is operated in a similar manner to the valve 30, may be open and closed for approximately the same period of time, viz. fifteen minutes. To vary the time the valve 22 is open as compared to the time it is closed, the arm 26 attached to the valve spindle is adjustably mounted relatively to the float 24.

Abstract: 837,235. Foot supports. TAYLOR, N H. July 4, 1958 [July 5, 1957], No. 21290/57. Class 17(2) Foot deformities are corrected by constraining the foot to assume a correct anatomical position, making a mould of the foot, preparing a cast from the mould, and finally moulding on the cast a foot support with a rigid heel enclosing portion which can be inserted in the footwear to be worn by the patient. A thin skin of calf leather is used for moulding on to the cast, and lengths of surgical bandage soaked in a cold-hardening synthetic plastic cement stretched across the leather in all directions to provide a laminated structure, and allowed to dry. Plastic cork filler is then pressed on to the underside of the structure to simulate the heel seat of the shoe and provide a wedge effect below the heel and under the long arch. The structure is allowed to dry, and again bandage saturated in plastic cement is moulded thereover and allowed to dry. Further bandage and cork filler may be applied to shape the structure to the shoe, the structure is then trimmed below the metatarsus on both sides, keeping the edge high on the medial side, as at 131, low on the lateral side, as at 132, well up on the instep as at 133, and cut away as at 134. The structure is then smoothed and enamelled

Title: Improvements in or relating to the hardening of dry spun protein fibres
IPC: D01F4/00
Filed: 1943-12-22
Abstract: Dry-spun protein fibres, particularly fibres dry spun from caseinate solutions, are hardened in an atmosphere containing a gaseous hardening agent, e.g. an aldehyde or ketone, the atmosphere being from one-third to two-thirds saturated with water vapour.  Such an atmosphere may arise from a mixture of water, formaldehyde and sodium chloride, or a saturated solution of formaldehyde in the presence of fused calcium chloride.  Gaseous hardening agents which may be employed are formaldehyde, acetaldehyde and quinone, and the hardening treatment is effected at room temperature.  After hardening, the fibres are treated with dilute acid to free them from basic substances employed in the spinning solution.  Examples are given in which fibres dry-spun from sodium caseinate solution are suspended in a closed chamber for several days and subjected at room temperature to the vapours arising from an aqueous solution of formaldehyde saturated with sodium chloride or an aqueous formaldehyde solution containing fused calcium chloride.  The hardened fibres are subsequently treated with acid, washed and dried.

Abstract: 998,420. Packaging machines. GENERAL FOOD CORPORATION. June 4, 1962, No. 21596/64. Divided out of 998,419. Heading B8C. In the filling of a container with free-flowing aromatized soluble coffee, coffee is passed to a gas-tight storage zone, a slight positive inert gas pressure is maintained above the surface of the coffee in the zone, a container is maintained below the storage zone and in communication therewith, pressure is formed in the container which is lower than in the storage zone, whereby particles of the coffee pass under the influence of the pressure differential from the storage zone to the container, thereby diminishing the pressure differential, and the pressure differential is intermittently reformed until the container is filled with the coffee. A free-flowing aromatized soluble coffee, e.g. that prepared according to the process described and claimed in Specification 998,419, is filled from a storage hopper 4 into a container or jar 12 by maintaining above the surface of the coffee in the hopper a slight positive pressure of up to 0À5 inch water gauge (preferably 0À3 inch) of an inert gas-carbon dioxide or nitrogen from a pressure source 5- providing an atmosphere containing less than about 0À5% by volume of oxygen, applying to the container a pressure which is lower than that in the hopper whereby particles of the material pass into the container under the influence of the pressure differential, and intermittently reforming the pressure differential. During a filling time of 4-5 seconds a pressure differential typically of from 1 to 28 inches of mercury, may be redrawn 3-4 times. Vacuum and pressure from sources 28 and 5, respectively, are transmitted to the container through lines 16 and 15; the sequence of operations viz. vacuum-pressure-vacuum is accomplished by valves (not shown) actuated by spring blocks 19 in a timed relationship determined by cams 22 to 25 rotating on a spindle 20.

A reciprocating gripper shuttle has gaps 8, 9 in which the weft is caught and cut. In operation, with the shuttle at the right-hand side of the loom, it is picked so that a previously laid weft which extends from the selvedge to the spool is guided into the gap 8. Movement of the shuttle cuts the weft on a cutting edge 11 and the weft is drawn from the spool and laid. At the left-hand side of the loom the spring-loaded flap 6 is momentarily opened to release the thread and the shuttle is picked back to lay a thread by use of the gap 9.
