Title: Improved apparatus for conveying letters and like postal packets between sorting andclearing stations in post offices
IPC: B07C3/08
Filed: 1928-03-13
Abstract: 308,077. Doherty, J. H. March 13, 1928. Letters and the like, systems of transmitting and delivering.-In order to convey letters and postal packets from sorting stations to despatch stacking points, where a number of sorters are employed on one batch of letters, the letters are sorted into slots, preferably arranged in rows, in vertical frames, the letters being intermittently removed, by 'horizontal rotable gripping arms, from behind the frames to separate conveyers associated with the slots. In the embodiment, the letters are sorted into holes 1 in a plate 2, Fig. 1, and are gripped between a loose roller 3 and a driven roller 4, being fed into collecting boxes comprising a rigid tongue 8 and a spring tongue 9, Fig. 14. A bar 10, keyed to a shaft 11, is formed with movable jaws 12, 13, having gripping blades 14, 15 respectively, Fig. 7. The jaws 12, 13 are guided by a slot 16a, Fig. 11, in the bar 10. The jaw 12 has a yoke 16, and a pivoted locking catch 17 connected to a finger 18. The catch 17 is adapted to engage in locking grooves 19, Fig. 11, in the bar 10. A rod 22, connected to a crank 21 on the shaft 11, has a pin engaging in a groove 23, Fig. 2, in a cam disc 24 keyed to a shaft 6, the groove 23 being shaped so that, as the shaft 11 rotates, the gripper jaws are swung from above the conveyer 25 to under the collecting boxes. A wedge cam piece 26 then closes the blades 14, 15 to grip the letters, the catch 17 falling into the grooves 19 to prevent further relative movement of the blades 14, 15. The jaws then swing back over the conveyer, where a wedge pin 27 disengages the pin 18 from the groove 19 and then forces apart the jaws 12, 13 to release the letters, which fall between spaced guide plates 27 on to the conveyer 25. Preferably the conveyers are placed between plates 2 and are fed by jaw elements from each side. In order to enable a conveyer to pass letters round a corner, a gripping device, shown in Fig. 5, is provided, comprising a bar 31 mounted on an oscillating shaft 32 and fitted with movable jaws 34, 35 to take up the letters received in the spring-box ends 36 of the guides 28. The bar 31 then swings to deposit the letters on a second conveyer 29.

Title: Improvements relating to permanent waving of hair
IPC: A45D2/32
Filed: 1930-03-08
Abstract: 350,448. Hair - waving appliances. KERKA, F., 28, Denmark Street, London. March 8, No. 7681. [Class 131.] Curlers upon which the hair is wound during permanent waving are formed with the outer end of a smaller diameter than the inner end which is applied to the root of the hair, so that, upon rewaving, the part of the hair previously waved is wound upon a part of the curler that is of smaller diameter than the part of the support upon which it was wound when previously waved. The curler may taper uniformly from the inner to the outer end, may have a cylindrical inner end and taper to the outer end, or may comprise two conical portions tapering either in the same or in opposite directions. As shown in the Figure, the curler comprises a tubular body a and a central rod b, the body a gradually increasing in diameter from the inner end, adjacent the end b<1> of the rod b, for about onethird of its length, and then decreasing in diameter to the outer end a<1>, which is of less diameter than the inner end. The rod b is attached at the outer end to a head c secured to a cap d, a spring e positioned within the cap acting as a one-way clutch and allowing the body a to be rotated in one direction relatively to the rod b, to tighten the hair.

Abstract: 124,760. General Chemical Co., (Assignees of Jahn, F. W. de). Nov. 3, 1917, [Convention date]. Catalytic apparatus; hydrogen from mixtures of steam with carbon monoxide, catalytic production of.-Carbon monoxide contained in gas mixtures, such as the mixture of nitrogen, carbon monoxide, and hydrogen produced according to Specification 120,546, is converted into hydrogen and carbonic acid by mixing the gases with steam and treating the heated mixture with a catalyst such as iron oxide. The catalyst is contained in a chamber 39 and is disposed on a grate 40. Above the catalyst are arranged perforated plates 41 to distribute the gases. To avoid leakage, the chamber 39 is supported on legs 58 provided with rounded steel insertions 60, Fig. 3, resting on steel surfaces 61 to allow freedom of motion. To start the operation, a producer-gas flame is employed in a chamber 54, which heats the gases to a sufficient temperature and is then shut off. A series of heatexchangers 47 is employed in association with the catalytic chamber 39, the course of the gases being as shown by the arrows, Fig. 1. Steam is supplied by a pipe 48. If the temperature of the chamber 39 falls too low, as indicated by a pyrometer 42, the necessary heat is supplied by the burner 54. Alternatively, the heat-regulation may be effected by electrically-heated coils or other means.

Abstract: 572,005. Thermal switches. GENERAL ELECTRIC CO., Ltd., JENKINS, H. G., and NOBLE, S. H. June 10, 1942, No. 7967. [Class 38 (v)] A thermal glow switch for starting discharge devices is arranged for the thermal element to be heated, alternatively to the " glow," by a heater operating when the switch is closed. This is effected in the example by carrying one contact 11 in the free end of a bimetal U-strip 1, the fixed end being connected to a heater 4 enclosed in a heat-storing case. On switching on, " glow " occurs between contacts 10, 11 and the glow current also heats heater 4 until contacts 10, 11 meet.

The cancelling signal thus has less effect on the amplitude of the required signal transmitted rearwardly by the transmitter 5.
