Patent GB-589775-A (GB)
Title: Refuse body
IPC: B65F3/28
Filed: 1945-04-04
Abstract: 589,775. Vehicle fittings for loading and unloading. BURGESS, A. F. (Anthony Co.) April 4, 1945, No. 8292. [Class 78(iv)] [Also in Group XXIX] A refuse-collecting vehicle comprises a refuse-receiving container with a rear gate, normally held in the closed position, and a blade, conforming in shape to the section of the container, which is movable, by means wholly above the refuse zone, longitudinally of the container so that the refuse may be packed against the door during the loading of the container, and finally discharged by the blade, through the open door. As shown, the body is mounted on a vehicle frame 5 and has a closed front end, a hinged door 15 for closing the rear end and hinged sliding or removable covers 13 for charging openings in the sides. It has a central longitudinal well between the vehicle wheels. A blade 20 is carried by a trolley 24 mounted to run in channel members 23 in a slot in the top of the body, the trolley being actuated by a hydraulic cylinder 30 and cables arranged around sheaves on the cylinder body and on crossheads 34, 46 on the piston rod, the cables being anchored to brackets 29 on the trolley. In use, the blade is moved to the closed front end of the body, the refuse is inserted through an open door 13 and periodically is compacted against the closed door 15 by moving the blade rearwardly. The refuse is discharged by the blade 20 when the door 15 is open. Safety-means are provided for limiting the pressure supplied to the cylinder 30 for moving the blade 20 towards the open end of the body, a higher pressure being permitted when'the door 15 is open than when it is closed. The hydraulic system comprises a pump 4 which supplies pressure fluid through a pipe 78 to a valve 79 controlling two pipes 80, 81 leading to opposite ends of the cylinder 30. Return fluid is received in a sump 79b. Manipulation of the valve 79 therefore effects movement of the blade 20 in one direction or the other. The safety-means consists of spring-loaded valves 66, 69 in a casing connected to the pump pressure system by a pipe 61 and having a low-pressure return pipe 73. A sliding member 77 is urged by a spring 75 to close the passage 65 of the valve 66, and to open the passage 68 of the valve 69. When the door 15 is closed, the member 77 is forced back to open the passage 65 and close the passage 68. The spring 67 is relatively weak, so that when the door is closed, the pressure supply pipe is vented, and the cylinder 30 consequently made inoperative, at a lower pressure than is the case when the door 15 is open and the strong spring 70 has to be overcome.

Abstract: 705,633. Centrifugal separators. DE LAVAL SEPARATOR CO. April 2, 1952 [April 9, 1951], No. 8403/52. Class 23 Solid particles are separated from a liquid of lower specific gravity than that of the particles by passing the mixture through a centrifugal separator having an outlet for particles located at a smaller radius from the axis of the separator than that of an outlet for liquid carrying fine particles, by concentrating the liquid carrying fine particles discharged from the separator to form a sludge, and by returning the sludge to the separator. The separator comprises a rotor 11, a distributer 17 rotating at a lower speed than that of the rotor, and a conveyer 26 fixed to the distributer and moving the particles 36 against the action of centrifugal force to discharge through the outlets 15. The mixture supplied by a pipe 19 is fed to the interior of the rotor through holes 20a in the distributer. The liquid carrying fine particles discharged through the outlets 14 in the rotor is carried by a pipe 28 to a centrifugal separator 29 which concentrates the fine particles to form a sludge and which discharges clear liquid through a spout 29b. The sludge is led by a pipe 32 and returned to the interior of the rotor through holes 22a in the distributer. Liquid from a pipe 33 is discharged through holes 24a in the distributer to wash the particles as they are conveyed towards the outlets 15. The separator 29 may be replaced by gravity settling, filtering or other concentrating means.

Abstract: 671,099. Making tubular pins. ELASTIC STOP NUT CORPORATION OF AMERICA. April 5, 1950 [April 6, 1949], No. 8544/50. Classes 83 (ii) and 83 (iv). Curving; shearing; rolling; sheet-metal feeds.-Short tubular pins are made from strip stock by feeding and longitudinally grooving the stock, shearing it into lengths equal to the circumference of the pin, feeding the blanks at right angles to the grooves to bending rolls which shape the blanks into pins and break the blanks at the grooves solely by the bending action to form short pins. The stock is fed by rolls 17, 20 between freely-rotated rolls 51 with V projections and a plain roll 56 which form grooves 11a in the stock and past edge scarfing cutters 92 which form bevels 11c. The rolls 51, Fig. 5, not shown, are adjusted by screws against the urge of springs. The strip passes along guides and is sheared into lengths 13 by feeding and shearing mechanism set forth in Specification 661,832, [Group XXXII]. The blanks are then fed by pins on a chain 106 in a direction transverse to the grooves and to the. grain structure of the material to feed rolls 111 of a roller bender 14. The blanks are bent to cylindrical form by rolls 120 as set forth in Specification 678,005. At the bending stage, Fig. 21, the blank starts to break along the grooves 11a due to the bending stresses and the blanks eventually separate along the grooves to form short pins which are formed to cylindrical shape by further bending rolls.

Title: Bobbin thread case opener mechanism
IPC: D05B57/26
Filed: 1960-03-15
Abstract: 871,101. Sewing machines. SINGER MANUFACTURING CO. March 15, 1960 [April 6, 1959], No. 9054/60. Class 112 Bobbin case-opener mechanism in a lock stitch sewing machine is characterized in that a pair of stop members, movable in unison toward and away from the axis of rotation of the looptaker, co-operate each with one of a pair of abutment surfaces carried on the bobbin case and disposed on that side of the path of needle reciprocation from which the looptaker beak moves in engaging a needle thread loop, said abutment surfaces being spaced angularly and at different radial distances from said axis of rotation, whereby the movable stops are positioned alternately in engagement with their co-operating surfaces for passage of a thread loop in succession therebetween. The base 11 of the bobbin case is formed with a low radial projection 30 and a high radial projection 31. A curved arm 35, carried on a bracket 38 pivoted on a fixed pin 39, is secured adjustably by a screw and slot connection 41, 42 to an arm 43 also pivoted on pin 39. A forked end 44 of arm 43 embraces a three-lobed cam 45 on the looptaker driving shaft 16, whereby arm 35 is moved toward and away from the shaft. Arm 35 is closest when the looptaker is spreading the needle thread loop, and in this position, Fig. 1, a stop member 36 on arm 35 engages an abutment surface 32 on projection 30 to hold the bobbin case stationary. A second stop member 37 on arm 35 is then spaced from projection 31 to provide a gap for the inward passage of the front limb F of said thread loop. Arm 35 is farthest from shaft 16 when the needle thread take-up is operating, Fig. 5, whereby member 37 engages an abutment surface 33 at the outer end of projection 31 to hold the bobbin case stationary, while member 36 moves clear of surface 32 to provide a gap for the outward passage of thread limb F. It is stated that surfaces 32 and 33 are preferably formed as arcs concentric with pin 39 and are then so dimensioned that member 37 engages surface 33 before member 36 is free of surface 32.
Patent GB-615914-A (GB)
Title: Improvements in or relating to concentration of vitamins
IPC: A61K31/59
Filed: 1946-03-25
Abstract: Vitamin A and D concentrates are obtained from fish oils by countercurrent extraction of the oil with a polar organic solvent which is a partial solvent for the oil and is relatively insoluble in naphtha, in a ratio of about 3-30 parts of solvent per part of oil, at such a temperature that about 2-30 per cent of the oil enters the solvent phase, and subsequently washing the solvent extract with naphtha.  The vitamins and antioxidants in the oil which are extracted by the polar solvent are thus transferred to the naphtha solution from which they are recovered by distillation.  Suitable polar solvents are chosen from alcohols, esters, carboxylic acids, nitriles, carbamic acid esters, organic carbonates and phosphates, nitro compounds and amides.  Suitably the extraction is carried out in a vertical column.  The glyceride oil is introduced at a point midway up the column and the polar solvent is introduced near the top.  Raffinate oil is taken off at the top of the column and after being stripped of solvent may be passed to storage or transferred to another column for further extraction.  The vitamin enriched solvent fraction is taken off at the base of the column and is transferred to a further column where it is contacted with naphtha.  The naphtha phase is drawn off and the solvent removed by distillation, leaving the vitamin concentrate.  Modifications of the process allow the extract and raffinate fractions to be recycled to give more thorough extraction of the oil.  In examples (1), (2) and (3) dogfish liver oil containing 17,200 units of vitamin A per gm. is extracted with furfural saturated with naphtha to give a raffinate containing 3,440 units of vitamin A per gm. and a solvent phase which is contacted with naphtha to give on distillation an extract with a potency of 92,800 units per gm.; (4) sardine oil is extracted by the method of (1); (5) dogfish liver oil is extracted with methyl acetoacetate as in (1) and (6) dogfish liver oil is extracted with the monomethyl ether of ethylene glycol as in (1).  Specifications 475,070 and 515,468 are referred to.
