Abstract: 1,057,525. Impact wrenches. FORGES ET ATELIERS DE MEUDON. June 15, 1965 [June 16, 1964; April 12. 1965], No. 25199/65. Heading B3N. A rotary impact wrench comprises a reversible pneumatic motor 23, Fig. 1 (not shown), a hammer carrier 26 splined to the motor shaft 22, a pair of hammers 27, 28 pivoted in slots 29, 30 in the carrier by pins 31, an anvil 45 in which the end 43 of carrier 26 revolves, and a camshaft 48 keyed for rotation with anvil 45, at 55. Hammers 27, 28 are constantly urged towards the wrench axis by coil springs 32. Fig. 5 (not shown), which move a yoke 34, Fig. 17 (not shown), so that its central face 35 engages the heels 36 of hammers 27, 28. The hammers are locked in their retracted position by a pin 60, 61 when a push member 58 or 66, Figs. 3 or 21 (not shown), urged by a spring 58, engages the small radius of cam 51, and they are released when the push member engagees the large radius, Figs. 4 and 22 (not shown). In operation, with the motor rotating carrier 26, Figs. 2, 9 (not shown), hammers 27, 28 strike the dogs 63 of anvil 45 and produce an impact once every revolution. In a modification, an impact is produced once every two revolutions by replacing push member 58 or 66 by an assembly of elements, Figs. 24- 36 (not shown). The assembly comprises a member 70, Figs. 27, 28 (not shown) slidable in a bore 42 in the carrier 26, a ratchet 72, Fig. 29, 30 (not shown), carried in a slot 71, in member 70, by a pin 73, Fig. 36 (not shown), a push member 74, Figs. 31-33 (not shown) slidable on face 80 of member 70, and a spring-urged pawl 88, Figs. 34, 35 (not shown). In operation. member 70 is moved so that the ratchet is indexed by the pawl, due to cam 51, Fig. 36 (not shown), but pin 61 is only moved to release the hammers when the end 76 engages the outside diameter of the ratchet, and not one of the holes 78 therein. This position, Fig. 40 (not shown), occurs once every two revolutions of the motor.

Abstract: 487,562. Roller-way conveyers. KRUPP GRUSONWERK AKT.-GES., F. Sept. 21, 1937, No. 25614. Convention date, Nov. 14, 1936. [Classes 78 (i) and 78 (iii)] [Also in Group XXII] Billets are conveyed from one roller bed 1, Fig. 1, coming from a heating furnace, to another 5 running in the same direction at some distance from it by trolleys 2 moving perpendicularly to the roller beds and capable of being raised and lowered. The trolleys are moved by an endless chain or rope 11 driven by a wheel 12 and guided by pulleys 13, 14, 15. Each trolley 2 has a pair of front wheels 7 running on rails 3 and a single rear wheel 8 formed as a double cone running on a V-shaped rail 4, Fig. 2. Beneath the roller bed 1 the wheels 7, 8 rest in depressions 9, 10 in the rails so that the platform 6 of the trolley is below the level of the bed. When the wheels leave the depressions, the trolley rises and lifts a billet from the rolls. At the end of its travel, the billet is lifted off the trolley by rocking arms 17 fixed to a shaft 18, the billet first sliding up against projections 16 thereon and then tilting over through 180 degrees to fall on the platform 20 of a trolley 21 which is connected by a rod 25 and crank 26 to the shaft 18, so that the trolley moves towards and away from the shaft 18 as the arms 17 rise and fall. The trolley 21 is raised to receive the billet from the arms by its wheels 22 leaving depressions 23 in rails 24, and is lowered, when it returns to its position of rest, to'deposit the billet on the roller bed 5. An adjustable guide strip 27 positions the deposited billet centrally in the bed 5. The impact of the billet, falling from the arms 17, with the platform 20 loosens the scale from the rolled material. If the billet is not to be overthrown, the conveying trolleys 2 will run within the range of the roller bed 5 and be lowered to deposit the rolled material.

Title: Improvements in means for selectively cutting out a rectifier, on a back ignition taking place in the same
IPC: H02H7/12
Filed: 1926-10-14
Abstract: 262,062. Akt.-Ges. Brown, Boveri, et Cie. Nov. 27, 1925, [Convention date]. Addition to 251,539. Cut-out arrangements.-In the means for selectively cutting-out a mercury or other vapour rectifier when a fault occurs therein by utilizing the non-symmetry of the currents or voltages produced by the fault to actuate normallybalanced protective devices, as in the parent Specification, the non-symmetry is caused to act, magnetically, directly on the releasing systems of the circuit breakers. As shown in the Figure, the star points o<1>, o<2> of the two symmetrical star-connected secondary windings q', q<2> feeding the rectifier are connected directly through choking coils d', d<2> to two windings b<1>, b<2> which act differently on the circuit-breaker s. The negative of the direct current side is connected to the mid-point m between the windings b<1>, b<2> and, on the occurrence of a fault, the unequal currents in these windings produces operation of the circuit-breaker. The third harmonic voltage which appears between the star points is choked off by the chokes d', d<2>, or short-circuited coils in inductive relation with the windings b<1>, b<2> may be used to choke off this harmonic.
Patent GB-491119-A (GB)
Title: Improvements in or relating to the manufacture and treatment of cellulose compounds
IPC: C08B3/22
Filed: 1937-09-22
Abstract: The corrosive properties of organic derivatives of cellulose are reduced by treating the finely divided solid derivatives with organic compounds of basic reaction which are free from hydroxy groups, in the case of cellulose esters, under conditions such that no substantial saponification of the esters is effected. Suitable basic compounds are aliphatic amines, e.g. amylamines, p  diamines, e.g. ethylene diamine, and cyclic amines, e.g. pyridine, piccolines and butidines.  The process may be applied to organic esters of cellulose in the finely divided condition in which they are precipitated from the ripening solution or in which they are obtained after having been formed by a process in which solution does not occur, or in the condition in which they are obtained after stabilization.  The basic compound may be used in solution of 0,1 to 0,5 per cent strength, and in amount equal to 0,03 to 1 per cent of the weight of the cellulose derivative. Temperatures of 50 to 100 DEG  C. may be employed.  The cellulose derivatives may be treated with chlorine bleaching agents prior or subsequent to the treatment with the organic base.

Abstract: 890,849. Measuring electrically. KELVIN & HUGHES Ltd. Oct. 31, 1960 [July 31, 1959], No. 26338/59. Class 40 (1). [Also in Group XXXVI] A rate of climb indicator for an aircraft comprises an input member 1 which varies with static pressure, a potentiometer supplied by a reference voltage and having a wiper 13 driven by the input member for producing a voltage which varies non-linearly in relation to the displacement of the wiper from a null position, and an electric motor 4 driven by a voltage dependant upon the difference between the potentiometer output voltage and a voltage produced by a tacho-generator 5 driven by the motor 4, the motor being adapted to drive the wiper in opposition to the drive by the input member so that the wiper is driven to a balance position in which the output from the potentiometer is equal to the tacho-generator voltage and is proportional to the speed of movement of the input member. The input member 1 through a cam mechanism 2 drives a differential gear 3 according to the height. The output from the gear 3 drives the ganged wipers 9, 13 of two potentiometers 7, 8, the output from the first wiper 9 being applied to the ends of the second potentiometer 8. The two potentiometers have centre tappings 10, 11 connected to a common conductor 12. The other side of the differential gear 3 is driven from the electric motor 4 controlled by an amplifier 6, the input of which is the difference between the tachogenerator voltage and the potentiometer voltage. In use the wipers 9, 13 take up a position in which the input to the amplifier is zero, the motor 4 then rotating at the same speed as the input member 1, the tacho-generator voltage being proportional to this speed and the position of the wipers a non-linear (square) function of the rate of climb. The device may operate a suitable vertical speed indicator and/or supply information to an autopilot or flight director computor.
