Title: Tool for applying pressure clamps
IPC: B25B25/00
Filed: 1962-03-02
Abstract: 950,561. Shearing. BANDIT CO. March 2, 1962 [Nov. 16,1961], No. 8150/62. Heading B3W. [Also in Division F2] A tool for applying a pressure clamp or the like of the type including a buckle B and a strap 16, 17 adapted to pass therethrough and to be attached thereto includes a nose end 30 and means 22, 28 for applying tension to one end of the strap to enable the latter to be tightened around an article 9 to be clamped. The tool includes as an integral part thereof or as an attachment thereto (as shown) a unitary structure comprising a bar 38 extending across the nose for engaging one end of the buckle while the strap is tensioned and while the strap is bent up against the buckle, a shear blade 39 extending across the nose and spaced from the bar 38 to provide a passage 40 through which the strap passes, a lever-hook 50 pivoted at 51 and having a hook 54 for engaging the opposite end of the buckle and a cam 48 pivoted at 49 for actuating the leverhook through a cam face 61. The lever-hook applies a force through the buckle against the strap and the shear blade 39 applies a cutting force on the other side of the strap to shear the strap close to the buckle. The lever-hook has an edge 54 which is inclined relatively to the axis of the pivots 49, 51 when the cam 48 is actuated to apply force through the buckle against the strap and which causes the shear blade to shear the strap by a scissor cut progressively from one edge of the strap to the other. In one modification, Fig. 10, the leverhook has the edge 54 formed at an angle to the top edge 57 so that on applying pressure thereto by the lever 55 the tool skews in a direction for the inclined edge 54 to move into parallelism with the end face of the buckle which causes the shear blade 39 to be inclined to the adjacent end surface of the buckle. In another modification, Fig. 13, the cam face 61<SP>1</SP> is inclined to the axis of the pivot 49. The lever-hook has a flat top surface 58<SP>1</SP> and has the edge 541 parallel with the top edge 57<SP>1</SP> but is loosely pivoted at pivot 51<SP>1</SP> so that the lever-hook is inclined to the axis of pivot 51<SP>1</SP> on applying pressure by lever 55. This construction also allows the shear blade 39 to make a scissor cut. The strap is tensioned by clamping it in a slide 20 by a cam 24 and moving the slide along a frame 21 by a fixed screw 22 and an internally threaded handle 28.

March 18, 1931, No. 8357. Convention date, March 20, 1930. [Class 38 (iii).] A synchronous motor 10, with an amortiseur winding, is started with its wound field 12 open circuited by contactor 20 until 40 to 60 per cent synchronous speed is reached, whereupon contactor 20 closes the field through a resistance 18, and finally at about 95 per cent synchronous speed, contactor 21 operates to connect the field to a D.C. supply 14. Starting is initiated by closure of button 16 to cause immediate closure of contactor 15 and relay contacts 33. Time-delay device 23, such as described in Specification 241,883, [Class 38 (v), Electric switches &c.], causes subsequent closure of contactor 20, which brings into action time-delay device 24 to cause, after a further interval, operation of contactor 21. Opening of " stop " button 17 causes immediate opening of contactor 15 and reverse operation of contactor 21, subsequently relay contacts 33 open with a delay, and cause opening of contactor 20. Thus resistance 18 is used as a discharge path for a predetermined time. The time-delay devices 23, 24 may be replaced by devices responsive to motor speed, armature current, or frequency of currents induced in the field 12.

Patent GB-760575-A (GB)
Title: Improvements in and relating to the recovery of ascorbic acid
Inventor: PARTRIDGE STANLEY MILES
IPC: C07D307/62
Filed: 1953-03-27
Abstract: The invention comprises a process for the recovery of ascorbic acid from a solution containing mixed components by subjecting a solution to a treatment which includes ionic separation by contact with ion-exchange resin or resins whereby a second solution which contains the bulk of the ascorbic acid and is substantially free from un-ionized components, is separated from the original solution, oxidizing the second solution to convert the ascorbic acid into dehydro-ascorbic acid while leaving other ions substantially unaffected, subjecting the oxidized solution to ionic separation by contact with ion-exchange resin or resins whereby a solution containing substantially only neutral dehydro-ascorbic acid is separated from a solution containing substantially only other ionized components, and reducing the dehydroascorbic acid solution thereby reconverting it to ascorbic acid solution.  The first ionic separation may be effected by contacting the original solution first with a strongly acidic cation-exchange resin and then with a weakly basic anion-exchange resin, eluting the anionexchange resin with a strong acid to form the second solution.  Alternatively the ionicexchange steps may be effected in multichamber ion-exchange membrane cells which comprise alternating cationic membranes and non-selective membranes or alternating cationic and anionic membranes having an electrode at each end of the cell.  Prior to the first ionic separation the solution may be subjected to a preliminary treatment which consists in adjusting the pH to about 4 and an ionic separation to remove a substantial proportion of the ionized compounds.  Oxidation may be effected either at the anode of an electrolytic cell or by contacting with an appropriate quantity of chlorine or sodium hypochlorite.  Reduction of the dehydro-ascorbic acid may be effected by means of hydrogen sulphide or by catalytic hydrogenation.
