Title: Control device for the selector of printing telegraph machines actuated by sets of electrical impulses
IPC: H04L17/16
Filed: 1940-02-16
Abstract: 538,233. Type-printing telegraphy. OLIVETTI & CIA SOC. ANON., C., and MODIGLIANI, G. Feb. 16, 1940, No. 3026. [Class 40 (iii)] [Also in Group XXIV] Start-stop clutch mechanism controlled jointly by the receiving magnet and the driven cam shaft is provided with means which maintains the stop member in its active position at the end of a cycle even if the member controlled by the magnet does not take up its locking position, e.g. if the stop impulse is not received. The cam shaft 1 is normally arrested by the engagement of stop 3 with a stop lever 4 connected by link 11 to a lever 8 shaped to engage a detent 7 on a lever 6 carrying the armature 5 of the receiving magnet. In normal working, the start impulse causes detent 7 to release lever 8 and spring 12 moves lever 4 to release the catch 3, Fig. 2 (not shown). After a slight movement of the shaft, cam 14 via members 15, 17 moves levers 4, 8 into the position shown in Fig. 3, until the end of the rotation when spring 12 returns levers 4, 8 to the position shown in Fig. 1. According to the invention, lever 8 is provided with a pawl 21 which co-operates with detent 7 in such a way that if the stop impulse is not received normally and the detent 7 is therefore not in a position to keep the members 4, 8 in their locking position, the end of the pawl abuts the detent 7, Fig. 4 (not shown) and causes members 4, 8 to arrest the shaft.

Title: Improvements in and relating to the production of alloys of iron, nickel and chromium
IPC: C22B23/02
Filed: 1948-02-03
Abstract: Carbon-free alloys of iron, nickel and chromium are obtained by melting high carbon ferro-chromium and ferro-silicon, and when the carbon has separated, adding nickel to the melt, running the melt into a ladle, running the melt through a hole in the ladle bottom and back into the furnace leaving the slag and separated carbon behind, and finally adding to the melt limestone and chromite ore to form a slag which by exothermic action removes silicon from the melt.  The quantity of limestone added in the last stage should preferably be sufficient to prevent there being more than 20 per cent of silicon in the slag to ensure solution of chromite ore in the slag as it is added.

Abstract: 1,074,802. Rotary-piston I.C. engines. PERKINS ENGINES Ltd. Jan. 21, 1964 [Jan. 28, 1963], No. 3494/63. Heading F1F. In a rotary-piston I. C. engine of the trochoidal n and n + 1 lobe type, liquid coolant enters passages 51 and a chamber or cavity 52 within the three-lobed piston 22 through two or more pipes (58), Fig. 4 (not shown), which are lodged in the peripheral wall of a trough 57 in a lower end-wall 23 of a stationary two-lobed housing 20 for the piston, a plurality of scoops 47, helical passages 48 and horizontal passages 49 within a member 44 attached to the lower side of the piston, a vertical power-output shaft 30 being furnished with an eccentric portion 29 carrying rollers 28 that engage with a central bore in the piston. In operation, the scoops periodically receive jets of coolant issuing from the pipes (58), the coolant being directed into the passages 51 and the cavity 52 by centrifugal action. Surplus coolant issuing from the pipes (58) is collected in a trough 63 provided with a drainage passage 64 and is prevented from entering a bearing 41 for the shaft 30 by a ring 65 attached to the shaft. Coolant is ejected from the cavity 52 through passages (53), Fig. 10 (not shown), which are adjacent the apices of the piston, horizontal passages (55), Fig. 4, in the member 44, and pipes 56 extending into the trough 57. In a modification, Figs. 5 and 6 (not shown), the coolant is fed into a trough (73) carried by the shaft 30 through a passage (79) in the end-wall 23 and holes (80) in the bottom of the trough, the coolant being collected from the trough by helical passages (66) having flared entrances (67) and defined by a member (65) that is integral with the member 44. The passages (66) are connected to the passages 51 by passages (68, 69) in the member 44. Provision is made for ejection of coolant from the cavity 52 in a manner substantially similar to that in the embodiment shown in Fig. 3. In a further modification, Figs. 7 to 9 (not shown), the coolant is fed into an inverted trough (85) carried by the shaft 30 through a passage (89) in the end-wall 23 whence it is ejected by centrifugal action through a semicircular passage (90) that periodically comes into register with deflector blades (97) between concentric walls (95, 96) lying beneath an annular gallery (98) defined by a member (94) attached to the member 44. A port (100) in the gallery allows coolant to pass into the cavity 52. Again, provision is made for ejection of coolant from the cavity 52 in a manner substantially similar to that in the embodiment shown in Fig. 3. In a rotary-piston I. C. engine of the aforementioned type, the piston (104), Figs. 11 and 12 (not shown), has three lobes and is lodged in a four-lobed housing (108), coolant for the piston being collected from a trough (118) in the housing by a member (117) that is generally similar to the member (65) in the modification according to Figs. 5 and 6.

Title: Improvements in or relating to the manufacture of artificial staple fibre
IPC: D01G1/04
Filed: 1931-02-04
Abstract: <PICT:0372323/IV/1> Artificial filaments are cut into staple lengths and curled, by winding them on to a rod of small periphery, allowing them to remain on the rod long enough to acquire a permanent curl, and then cutting the filaments from the rod.  The rod may be heated to soften the filaments when they are of cellulose acetate or other organic derivatives of cellulose, either electrically or by circulating hot oil, air, water or steam inside the hollow rod, or by enclosing the rods in ovens, a temperature of 50-100 DEG  C. being suitable; or softening may be effected by winding the filaments continuously with their production and whilst they still retain some solvent; or substances such as vinyl acetate may be added to the spinning solution to maintain the filaments slightly soft; or, particularly when the filaments are unwound from supply packages, the solvent may be applied by passing the filaments over a wick or roller, or through a chamber containing the vapour or a spray of the solvent.  Suitable low boiling-point solvents are acetone, methyl or ethyl alcohol with ethylene dichloride or with dichlorethylene, medium or high boiling-point solvents are ethyl lactate, diacetone alcohol (alone or with water or alcohol), dibutyl tartrate, and tricresyl phosphate.  The process may be intermittent, e.g. by winding filaments on to the rod and cutting them off in a separate operation, or continuous, the filaments being cut from the rod substantially immediately after they have been wound on, e.g. the filaments are wound on the hollow rod 9 by the traverse guide 11 which is connected to a rod 13 carrying two knives 12 which project through a slot 14 in the rod.  The rod, together with the knives, is rotated, the filaments being traversed by the guide 11 and almost immediately cut by one of the knives 12 which follow the guide.  The rod 9 is electrically heated by elements 14<1>, current being supplied through brushes 15.  The filaments may be wound on the rod under tension, which may be great enough to cause permanent elongation thereof with a corresponding reduction in denier; the staple fibres may be removed by suction or air blowers or allowed to drop into a receptacle.  The staple fibres may be spun into yarn alone or with natural fibres or with fibres of other artificial materials.
