Compensating for wear.-Means for adjusting the length of transmitting mechanism to compensate for the wear of the brake block comprises a block b, Fig. 2, connected by a stirrup link a<1> to a lever a and having therein a split nut c which resiliently engages a toothed rod b<1> connected to the brake. The end of the rod b<1> is adapted on actuation of the brake to contact with a plate d<3> carried by a toothed rod d<1> which is held in a split nut d<2> mounted in a fixed block d. If the brake block has been worn sufficiently, the additional movement which it is necessary to impart to the rod b<1> causes movement of the rod d<1> through the nut d<2> to the extent of a tooth. The plate d' carries rods d<4>, which pass through openings in a plate a<4> mounted on the rod b<1> and have terminal nuts d*. On the return stroke of the brake, the plate a<4> contacts with the nuts d* and the nut c is pushed along the rod b<1> to the extent of a tooth, thus shortening the effective length of the transmitting rods. In a modification, Figs. 4 and 6, the blocks b, d comprise a number of tumblers f<1> pivoted on rods f and engaging shoulders f<2> on the rods b<1>, d<1>, the adjustment being effected by the dropping of a tumbler into engaging position.

IPC: B29C48/10
Filed: 1928-07-26
Abstract: 297,103. Kalle & Co. Akt.-Ges. Sept. 15,1927, [Convention date]. Apparatus for making films.-In cleaning tubular cellulose bodies, particularly those made from viscose, the difficulties arising from the development of gas within the bodies are mitigated by causing the bodies tq travel alternately inside and considerable distances, for instance 25 centimetres or more and preferably 200-400 centimetres, outside of the cleaning baths, Suitable apparatus is shown in Figs. 1 and 2. In each apparatus the gases accumulate in that part of the body lying above the bath, with the result that a considerable quantity of gas can accumulate before its removal becomes necessary. The number and length of the vats employed for the cleaning operation can be reduced below the normal because the action of the baths continues even when the tubular body is outside the bath.

Abstract: 281,399. Falconer, E. A. Sept. 3, 1926. Key holders for holding keys, tools, or other articles and allowing their release to a borrower on insertion of a key or token left in the device to identify the borrower, as in Specifications 11233/15 and 235,309 have a channelsection guideway e into opposite ends of which the member d hold the key &c. (not shown) and the releasing key or token c are inserted. A pivoted catch f of E-shape has its central limb f<1> projecting across the channel so that the catch can be rocked by endlong movement of the inserted member d or key c, and forked to engage the upper end of a rocking catch member k. Member d has two notches respectively engaged by the lower ends of the catches f, k as shown. When the key c is inserted, the catches are rocked to release the member d, the upper end of the catch f at the same time engaging a single notch in key c which is thereby retained in the device. To prevent accidental &c. movement of the catches, cam plates g are provided normally held in the guideway e by a spring not shown, so that a flange on the cam obstructs the path of the end of catch f, The flange is shaped so that insertion of the key raises plate g out of the channel e and clear of the end of catch f, which is thus free to be rocked by further endlong movement of the key. In a modification, member k is omitted, and member d has only one notch, member d and key c being thus interchangeable. Two or more catches f of different lengths may be provided in each device, requiring correspondingly spaced notches in the key &c.

Filed: 1923-08-29
Abstract: 203,332. Roucka, E. Aug. 31, 1922, [Convention date]. Recording by co-ordinates.-Variations in fluid pressure, flow of fluids, temperature, gas analysis conditions, &c., are indicated or recorded so that they may be compared with each other by operating recording mechanism periodically by impulses of auxiliary energy, the position of which in corresponding time intervals depends on the variation and forms a measure therefor. The devices sensitive to the variations to be measured are each connected to a recorder 140. Each recorder comprises electromagnets 135, Fig. 2, connected in circuit with a battery 110 and cooperating with an armature lever 133 which carries a type &c. 154 to produce, when operated, a record on a travelling strip 150. The magnets and type levers of all the recorders are mounted on a bar 160 which is reciprocated on rollers 162 by a synchronous motor 178. The time of one reciprocation of the bar 160 corresponds to the measuring time interval. Upon the production of each impulse from the battery 110 by the devices sensitive to the variations, records are produced on the travelling strips, and the position of the record on the strip forms a measure for the variations. Specification 191,395 is referred to.

Filed: 1955-07-29
Abstract: 771,280. Electric motors. PHILIPS ELECTRICAL INDUSTRIES, Ltd. July 29, 1955 [Aug. 3, 1954], No. 22013/55. Class 35. A four-pole synchronous motor 1 having a squirrel-cage rotor is correctly phased, e.g. for kinematograph work &c., by connecting it to a copper disc 4 having vanes 8 which pass between the poles of an electromagnet 5 fed with half-wave impulses through a rectifier 7 from the supply. In the wrong phase position the vane passes between the poles as these are magnetized by an impulse from the supply, thus causing sufficient braking to cause the motor to drop out of step. In the correct phase position, 180 degrees away the impulse energizes the magnet when the recesses between the vanes are presented between the poles, thus causing no braking. Specification 768,885 is referred to.
