Title: Improvements in or relating to props, especially pit props
IPC: E21D15/32
Filed: 1949-06-09
Abstract: 686,675. Pit props. ESSEN-BOTTROPER HANDELGES, [trading as SCHWARZ KOMMANDIT GES, H.] HEUSNER, W., and BREIING, T. June 5, 1950 [June 9,. 1949; Nov. 15, 1949], Nos. 15351/49 and 29163/49. Class 20(ii) [Also in Group XXV] A telescopic pit prop comprises a clamping collar 5, Figs. 1d which is supported on the lower part 3 and embraces the upper part 2 and has a radial thckness which increases from the ends to the central portion. The collar maintains its circular form when opened and closed and has a natural resilience by which it grips the upper prop member without the aid of external force. The clamp is opened d and closed by a tightening member 9 having a slot 11 and passing through holes in the end jaws 8, 12 of the clamp and a wedge 13 which is driven into the slot between the jaws to open the clamp to allow the prop to be set and is driven into the end of the slot against the outer side cf the jaw 12 to tighten the clamp on the upper part 2 so that the prop can take its full load. The clamp has a protective lining let into the inner wall. The upper part of the lower prop part may be slotted and the clamping collar pulls it against the upper prop part. In a modification the member 9 has a vertical slot for use in opening the clamps and a horizontal slot at right angles for use in closing the clamps and a wedge thrust member keeps the wedge 13 clear of the prop in the closing position. In further modifications a spring which indicates by its flexing the amount of tightening is arranged between the jaw 8 and the head 10 of the member 9. The jaws 8, 12, may be resilient. In a further modification, Fig. 7a (not shown), the upper part 2 has longitudinal radial ribs between which are wedges embraced by the collar 5 and the tightening member 9 is of circular crosssection so that the wedge can be driven in, in any direction. The ends of the collar extend towards one another and are thus closer together than the jaws to prevent localized pressure here when the clamp is closed. In a further modification, Fig. 1, the lower end of the prop has a screwed spindle 16 having rings 9 to allow it to be turned when the prop is being set and the collar 3 is held in position by the rim of a holder 6 riveted to the lower part 2 and a pin projecting from the upper part 1 prevents its withdrawal. In further modifications the collar is held on the lower part by a riveted lug or by a second collar integral therewith and clamped to the lower prop part.

Abstract: 457,456. Reciprocating pumps. STANWORTH, L., 11, Thorncliffe Avenue, Toronto, Ontario, Canada. May 27, 1935, No. 15366. Convention date, Jan. 26. [Class 102 (i)] A number of double-acting pumps 40 are fitted on a drum 9 and draw liquid through pipes 39 connected to ports 39x in the periphery of the drum and deliver it through a manifold 6 to the hollow shaft 7, pipe 51 and tank 50. The drum 9 is filled with liquid and rotates in the liquid container in the reservoir 1. Each of the pump piston rods 46 is attached by rods 47 to two floats 16 arranged on either side of the pump. As the drum rotates, the floats 16 vary their position relatively to the axis of the drum. The floats are triangular in shape and when nearest the axis of the drum the leading side is tangential to the shaft and guides 21, 30, 31 having axes arranged in this direction are provided for the floats. Several floats and pumps are arranged around the axis of the drum. The water under pressure in the tank 50 may be employed to drive a turbine 53 connected by shafts 54, 59 and worm gearing to the shaft 7 to provide part of the power to rotate the latter.

Abstract: 753,276. Television. STANDARD TELEPHONES & CABLES, Ltd. May 28, 1954 [June 2, 1953], No. 15836/54. Drawings to Specification. Class 40 (3). In an arrangement for supervising a television transmitter operating with negative modulation " whiter-than-white " pulses and pulses which reduce the carrier to zero are periodically added to the carrier modulated video signal which is then demodulated and displayed on a monitoring cathode-ray tube. By employing a suitable time-base repetition frequency the monitoring tube displays the levels corresponding to carrier zero, maximum white, synchronizing-level and the black-level as rows of dots which define lines corresponding to these levels. These levels are then made to coincide with standard levels (corresponding to correct operating conditions and either marked on the monitor tube screen or provided on a separate transparent plate) by adjustment of white, black and synchronizing level control devices.

Abstract: 637,460. Agricultural implements. KERR, D. J., and SMITH, D. C. S. June 18, 1947, No. 16158. Class 6 (i)] In machines comprising a power-driven steerable chassis 1 having tools 9 mounted for lateral movement simultaneously with the movement of the steerable wheels 6, tool carriers 10 are pivotally mounted on a transverse shaft 11 and a tool lifting member 15 is displaceable lengthwise of the chassis to engage the tool carriers to lift the tools 9. A loading spring 13 is connected between the member 15 and each tool carrier for urging the tools toward the ground. The shaft 11 is moved laterally by a bell-crank 33 and link 24 attached to a shaft 21 which is connected to the rear wheels 6 by chain and sprocket gearing 29, 30 and to a steering column 16 by reduction gearing 19, 20. The laterally adjustable tools 9 together with track erasers 59, 61 are lifted from the ground by a hand-lever 38 through links 45, 49. The track erasers 59 slide in a guide 55 and an arm 63 mounted on link 45 is connected to the rear eraser 61 by a Bowden cable 62. A pawl 26 connecting link 24 to the shaft 21 is connected to arm 63 by a Bowden cable 28. When the tools are lifted the pawl 26 is withdrawn and the steering wheel used solely for steering the rear wheels 6, which are connected to the brakes of driving wheels 3 so that on turning the vehicle the appropriate driving wheel is braked. The spacing of the driving wheels and tools may be varied to suit the plant rows. The Provisional Specification describes an embodiment wherein the withdrawal of the pawl by the lifting mechanism disconnects the rear wheels from the steering column which remains connected to the means for laterally moving the tools. The machine is steered by individual foot brakes on the driving wheels. Seed drills or spraying nozzles may be used in place of cultivating tools.

Abstract: 668,045. Moulding bands of thermoplastic materials. CELANESE CORPORATION OF AMERICA. June 29, 1950. [June 29, 1949] No. 16288/50. Class 87((ii). A band of thermoplastic material is extruded through a die 14, Fig. 4, and while still plastic is trimmed by knives 17 on a roller 15. The band is cooled while its cross-section is kept constant in the space 19 between the knives 17 and a ridge 18 on a roller 16. In a modification, the space 19 may be formed by corresponding groovesin in each roller. The rollers are cooled by passing cooling fluid through them. The upper roller is driven by contact with the lower roller and is pressed into contact with it by springs 37 which allow the roller to move upwardly, thus preventing damage if foreign material enters the space 19. Both rollers are adjustable vertically to enable the space 19 to. be brought opposite the die 14. Spaces 21 are provided to receive the material cut off by the knives 19. The band is retained in the space 19 during cooling by a retaining roller (53) Fig. 1 (not shown). The band is wound on to a take-up reel driven through a friction clutch. The extrusion die may have heaters 71, 72 wrapped around it and may have stainless steel filters 64. The trimming apparatus is mounted on rails 75 so that it may be moved to and from the extrusion apparatus.
