Abstract: 405,376. Hair waving appliances. BADGE, A. E., 39, Petherton Road, Canon- bury, London. Sept. 10, 1932, No. 25234. [Class 131.] In hair - waving apparatus comprising spring-pivoted handles 8, 10 carrying two sets of interfitting tubes 1, 3, 5 and 2, 4, 6 respectively, the tubes being adapted to be heated, means are provided for gripping the hair, as at the roots, where it enters the apparatus and further means are provided for holding the tips of the hair curled around the outermost tube 6. The root ends of the hair are gripped between rubber strips 14 mounted on spring metal strips 13 and adapted to contact before the tubes are completely closed together. Alternatively, only one strip 14 may be provided, the hair being gripped between it and the tube 1. The tips of the hair are held curled by a split perforated spring metal tube 18 or by an arcuate section spring strip. In the case of a strip, this may be provided at both ends with spring clips or with a spring clip at one end and a hinged two-part clip at the other for attachment to the tube 6. The tube 5 may be shortened to provide room for the hinged clip or this may be replaced by a knurled knob having a hole adapted to engage a pin extending from the end of the tube 6. The strip may be hinged to the knurled knob. The two sets of tubes may be provided with fingerpieces 15, 16 and fastened together by a hasp 17. The tubes may be heated by interior electric elements selectively put into connection by wander plugs with main leads, or pre-heated metal rods may be used. In a modification, interfitting corrugated metal blocks are provided in addition to the tubes and placed adjacent the tube 6. The curling strip or tube 18 is then adapted to be attached to a further tube carried by one of the blocks. In another modification, the tubes 1-6 may be screw threaded and carry intermeshing pinions at their ends. The tubes may then be rotated by the knurled knob of the end curler fitted on the tube 6 or this tube and its pinion may be fixed so that the other tubes rotate as the sets close together. The hair is thus drawn tightly into a waving position. The tubes may be heated externally by pivoted flat rectangular metal jaws heated electrically and, if desired, in selected sections.

Abstract: 462,910. Automatic exchange systems. AUTOMATIC ELECTRIC CO., Ltd., TAYLOR, R., and BAKER, G. T. Sept. 17, 1935, No. 25806. [Class 40 (iv)] A subscriber's meter MTR is normally disconnected, has one end of its winding connected to ground over a contact k2 of the cut-off relay when a call is made, and is operated by booster current applied over the holding lead and wiper M1 (or M2) when the called subscriber replies. The wiper M1 is also used for testing during the rotary movement of the finder, marking potential being applied over contact l4 of the line relay and upper vertical wiper VW whereby a holding circuit for the rotary magnet RM is closed, when the calling line is found, over front contacts rm of the magnet, the testing circuit also including relay HA (or HB) and ground in the common control-circuit. The cut-off relay K is operated over a separate wiper P1 (or P2) by the test relay HA (or HB). A rectifier MRA prevents the test relay from holding in series with the meter when the calling subscriber hangs up and also prevents the vertical magnet from operating when a testing earth is applied to the test wire at T, Fig. 3. The system described is similar to that described in Specification 456,750 involving normal or first-choice finders linked to group-selectors and overflow or second-choice finders associated with secondary finders, the operation of the finders being controlled by common allotting apparatus. The latter are such that by transferring a strap connection the normal preselecting operation involving a stepping relay may be cut out and a self-interrupting circuit closed to test the operation of the allotter magnet. Specification 391,151 also is referred to.

In a tool-holder of the type having an opensided recess at the forward end of a body to receive an elongated cutter or bit, means are provided to clamp a cutter bit in the recess comprising independently slidable means one on each side of the body, a projection on each of said means, said projections embracing and gripping the bit at each side of the body, and mechanical means to exert a clamping force on the bit and capable of causing displacement of the respective slidable means to slightly different extents to ensure that both slidable means are caused to grip the bit. A tungsten carbide tool bit 14, Figs. 1 and 3, of square triangular, circular, &c. section, is seated in a recess 12 in the tool-holder body 10. A pair of spring-steel finger-pieces 22, 24, Figs. 3 and 4, overlap the bit and are slidably guided in grooves 30 in the body. The rear ends of the finger-pieces are held together by a transverse hexagonal pin 34 and spring clips 38 engaging grooves in the pin. The latter is capable of moving in a slot 32 formed in the body, and the conical end of a set-screw 40 engages one face of the pin to force it rearwardly and thus draw back the finger-pieces to clamp the bit in its recess. A screw 16 adjusts the bit prior to clamping. When the bit 54, Fig. 6, after repeated sharpening, becomes too short for clamping, a backing-piece 50, of the same crosssection over most of its length, is rotatably secured to a height-adjusting screw 60. The end 56 of the backing-piece is of reduced crosssection to equalize the pressure on the tool-bit and the backing-piece.' Specifications 685,901 and 742,359 are referred to.

Abstract: 1380661 Tensioning endless conveyers ALLISCHALMERS CORP 31 May 1973 [6 June 1972] 25907/73 Heading B8A The bearings 22 of an endless chain conveyer are adjusted to maintain a desired tension in the conveyer chains, by each bearing 22 being slidably movable relative to the conveyer framework 42, under the action of a motor 60 so that one or more shims 90 may be inserted to define a new bearing position. The motor 60, as shown, is an hydraulic unit, a member 64 of which, is located in a recess 68A in the framework 42, there being a further abutment 80. This arrangement permits the adjustment of the position of the motor to an alternative position defined by a further recess 68B and associated further abutment 82. This position of the motor is necessary when the amount of movement of the conveyer bearings is more than can be provided by full deflection of the motor 60 in its first position. In order that the bearings may be held in position while the motor 60 is being changed from the recess 68A to the recess 68B, a locking screw 84 is provided. In carrying out an adjustment, the cylinders 60 are pressurized by means of a detachable pump unit 6. This causes projection of a piston 64 which bears on an abutment surface 41 rigid with the housing of the conveyer bearing housing 40. When the conveyer chains (16) (Fig. 1, not shown) have been tensioned to the desired amount, one or more shims 90 (Fig. 3A) are inserted between the abutment surface 41 and an end face of the cylinder of the motor 60. The conveyer described is an endless grate for feeding mineral ore pellets (A) to a rotary kiln (14).
