Title: Improvements in or relating to devices for mechanically extending and retracting thedrawers or the like arranged in desks, file cabinets or the like
IPC: A47B88/04
Filed: 1956-06-12
Abstract: 835,739. Drawers. BECKER, O. A. June 12, 1956 [June 13, 1955; March 16, 1956], No. 18114/56. Class 52(1) [Also in Group XXV] Desk drawers are operated by flexible operating means extending lengthwise of the drawers to which any drawer is coupled as required. A driver strip 12 is fixed vertically between two horizontal endless chains 15, 16 set at the top and bottom of the pedestal, coupled together by a chain 35 and driven by an electric motor. A pin 17 on the driver strip is engaged by a pivoted spring biased catch 18 at the back of the drawer, the catch normally being held clear of pin 17 by a catch 23 at the back of the pedestal and released by actuation of a press button appropriate to the drawer. Simultaneously the button closes contacts energizing an electric motor, this causing the drawer to be opened. On reaching the end of its outward travel the driver strip 12 contacts a buffer 40 opening a contact and de-energizing the motor. A latch holds the drawer in the opened position. Depressing a return button closes a switch reversing the direction of the current flow to the motor, which thus closes the drawer. In the fully closed position the drawer pivots a bellcrank lever 46 which releases the depressed buttons and closes the contacts associated with the buffer 40. A stop button is also provided which on depression holds open the circuit to the electric motor by a pivoted catch, released only by depression of a release button. In a modification each drawer is extended by spring force derived through cable wound on a spring-loaded drum fixed at the back of the pedestal and passing over a pulley at the front of the pedestal to be secured to the back of the drawer. The drawer is returned by a motor driven rod similar to the rod 12 already described and normally positioned at the front of the pedestal, to which position it is returned after closing the drawer. In further embodiments modifications are made to allow the use of spring force in both opening and closing the drawers, the electric motor tensing the spring in the cable drum used for opening the drawer. Alternatively, using the electric motor directly as in the first embodiment, provision is made for automatically closing one drawer on selection of another to be opened. The device may also be adapted for opening a drawer either from the front or back of a pedestal. The chain drive for the driver strip may be replaced by a friction- or toothed-wheel drive.

Title: Improvements in or relating to surgical trusses and abdominal belts
IPC: A61F5/26
Filed: 1935-06-25
Abstract: 458,983. Surgical trusses and belts. BEASLEY, L. E., 23, Fircroft Road, Upper Tooting, London. June 25, 1935, Nos. 18217, 24155, 24494, and 28736. [Class 81 (ii)] A surgical truss or abdominal belt comprises an arcuate strip of spring steel varying from approximately semicircular to circular form and having one or more pads or a plate disposed against the convex face of the spring and freely slidable thereon, the ends of the spring, which project outwardly from the wearer when not in use, being drawn apart to apply pressure to the pads or plate when the truss or belt is put on. In a modified form, the plate itself forms the spring and is freely slidable on a girdle or belt. The radius of the circle, to an arc of which the spring is bent, may vary from 1¢-6" for a single hernia. For a double hernia one or two springs may be provided. The spring 1 may be cranked at 10, 11, Fig. 1, so that the pressure on the pad is greatest at the bottom, and may have extensions 2, 3 pivoted thereto at 4, 5, their movement being limited by pins and slots 7, 6. It is encased in a leather cover secured to or forming part of a girdle 12, Fig. 3. The pad 14 is slit to form a loop 17 through which the girdle and spring pass. The umbilical truss, Fig. 11, has an oval plate 1 which is bent to a semicircle or more and constitutes the steel spring. This carries a fixed knob 33, padding 34, and rubber tubing 36, the plate being freely slidable on the girdle 12. Alternatively, the plate 1 may consist of a spring strip carrying a plate of, e.g. leather. Fig. 14 shows an abdominal pad in the shape of a heart with extensions 38, 39. This is looped at 42, 43 to slide on the spring. A truss pad, Fig. 7, comprises a half-pear shaped casing of soft rubber filled with sponge rubber and having at the back a resilient member 73, e.g. a strip of spring steel, of arcuate form with its concave side towards the front of the pad. The member 73 may be rectangular or may have lateral arms 75, 76 at the top or bottom and is secured by a number of backings, the last of which 79 is slit to form a loop receiving the girdle and arcuate spring of the truss.

Title: Improvements in or relating to a Two-Way Plough
IPC: A01B3/421
Filed: 1968-04-19
Abstract: 1,192,686. Two-way ploughs. INTERNATIONAL HARVESTER CO. 19 April, 1968 [24 April, 1967], No. 18542/68. Heading A1B. In a two-way plough a plough carrier 22 is pivotable with a sleeve 21 about a tubular member 16 and there is a lostmotion arrangement and a latch means to prevent the carrier when being moved from a first ploughing position to a second ploughing position from being bounced backwards when an overcentre position is reached and before movement in the opposite direction is effected. The lostmotion is obtained by having a ram 33 pivoted by a pin 34, in an opening 40 which is in a standard 35 and which is larger than the pin. When the ram swings the plough carrier and a transverse bar 23 upwardly, the ram is fully retracted at approximately 12 degrees before a dead centre position is reached. The lost-motion arrangements allows the momentum generated to throw the assembly over the dead centre position and approximately 12 degrees beyond, Fig. 3 (not shown). The latch mechanism comprises a dog 47 freely pivoted on the bar 23 and a latch part 44. As the assembly moves over the centre position the dog 47 abuts an inclined side 45 and prevents rotation backwards. The outer end of a piston rod 37 is connected to a lug 39 on an angle bar 30 which is between two plates 28 on the bar 23. The angle bar 30 fits in a groove in a plate 32 and the lower plate 28 rests on an adjustable pin (29), Fig. 3 (not shown). (For Figures see next page.)

Title: Improvements in and relating to the purification of lipid mobilizers
IPC: C07K14/47
Filed: 1959-06-08
Abstract: The lipid mobilizer of Specification 814,491 is purified by adsorption from aqueous solution and separating the liquid mobilizer from the adsorbent either by dissolving the adsorbent in a non-solvent for the lipid mobilizer and separating the lipid mobilizer from the resultant solution or eluting the liquid mobilizer from the adsorbent with a solvent.  A water-insoluble adsorbent soluble in organic solvents such as benzoic acid and phthalic acid may be used; in which case, a solvent for the adsorbent which is a non-solvent for the lipid mobilizer is acetone, ethyl ether, chloroform, dioxan, methyl ethyl ketone and tetrahydrofuran. Alternatively an adsorbent insoluble in water and in organic solvents may be used, e.g. cellulose powder, diatomaceous earth or a cation exchange resin such as "Dowex 50" (Registered Trade Mark).  The eluent is acidified aqueous alcohol, e.g. aqueous n-butanol and acetic acid for the cellulose and diatomaceous earth adsorbents; and water or aqueous 0.3 to 1.0 molar ammonium formate for the resin adsorbent.  Alternatively, the lipid mobilizer may be precipitated from the aqueous plasma dialyzate at pH 3.5 to 4.0 by the addition of a water-soluble alcohol, e.g. ethanol.  Further purification is obtained by chromatography on a cellulose column.  It is preferred to subject the eluent obtained from the adsorbent step to the above solvent precipitation and chromatography steps.  The purified product may be administered in physiological salt solution. Specification 814,491 is referred to.
