Title: Centrifugal casting machine
Inventor: ANDERSON GARY DAVID
IPC: B22D13/06
Filed: 1965-08-26
Abstract: 1,056,989. Centrifugal casting. TORIT MANUFACTURING CO. Aug. 26, 1965, No. 36620/65. Heading B3F. Centrifugal casting apparatus comprises a support housing 13, Figs. 2 and 4 (not shown), in which is horizontally mounted a rotatable shaft 21. A counterbalance mould supporting arm 39 is secured to one end of the shaft 21 and spring driving means 34 is attached to the shaft, the rotational drive being effected through an overriding clutch 30, 31. Passages 21 and 45 are provided through the shaft and arm respectively and connect with chamber formed by a cap plate 89 which overlies the other end of the shaft 21. The chamber is connected by a conduit 95 to an external evacuating source so as to evacuate the mould when located on the mould support 49 on the arm 39. A spring-loaded clamp 64 holds the mould in position on the arm during operation. The drive spring is wound up manually by rotating the arm which is then held in position by the slidable stop bar 82. Releasing the stop bar 82 permits the spring energy to rotate the arm and mould with the shaft to effect the casting operation.

Abstract: 1314364 Flame-retardant fibre board CANADIAN FOREST PRODUCTS Ltd 29 July 1970 [12 Nov 1969] 36627/70 Heading D2B A flame-retardant fibreboard having a substrate of lignocellulosic fibres has a surface layer comprising a mixture of lignocellulosic fibres and silicate material, the weight of the silicate material exceeding that of the lignocellulosic fibres and the silicate material comprising at least in part calcium silicate or zinc silicate. The silicate material may also include asbestos fibres preferably in amount 40-90% by wt of the surface layer. When no asbestos is present the Ca or Zn silicate may form 25-75% by wt of the surface layer. The fibre-board is produced by forming a substrate mat of wet lignocellulosic fibres, providing a surface layer on the substrate mat of a slurry comprising lignocellulosic fibres and silicate material which contains Ca or Zn silicate formed by precipitation from chemical solutions added to the slurry, and after said precipitation, draining and pressing the resultant layered structure to form the board. After draining the slurry may be provided with a release element or agent prior to pressing. The fibreboard may be embossed.

Title: Improvements relating to electronic counting chains
Inventor: WHITE EDGAR IAN
IPC: H03K23/42
Filed: 1958-11-14
Abstract: 879,579. Electronic counting-apparatus. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Sept. 18, 1959 [Nov. 14, 1958], No. 36656/58. Class 106 (1). In a multi-stage electronic counting chain employing a bi-stable transistor pair for each stage, the stages are first sequentially operated to produce a series of pulse outputs on a first set of output connections connected one to each stage and then sequentially reset to produce a series of pulse outputs on a second set of output connections connected one to each stage. The arrangement is suitable for use in a continuous scanning remote control system. As described, the stages, such as n, n + 1, of the chain are connected alternately to two leads S1, S2 to which stepping pulses are supplied alternately. The operation of the stages is as follows. Assuming the stage n to have just been switched from its normal state with transistor TR2 only conducting to its reversed state with transistor TR1 only conducting, the next stepping pulse is on the line S2 and is applied to the stage n + 1. However, with the transistor TR1 in stage n conducting, the pulse is shunted from the input for the stage n + 1 associated with its transistor TR2 over a shunt path P2 so that the pulse is effective only over the input for the stage n + 1 associated with its transistor TR1. Thus the stage n + 1 is changed from normal to reverse and an output pulse is produced over a capacitor and diode associated with the transistor TR2 of the stage n + 1. When the last stage N, Fig. 2, has been reversed, a reversing coupling RC is effective to shunt the next stepping pulse so that the pulse is effective only over the input associated with the transistor TR2 of stage 1. The stage 1 is therefore returned to its normal state and the subsequent stepping pulses cause the following stages to be returned in sequence. As each stage is returned to normal, it produces a pulse over the output connection associated with its transistor TR2. Since the reversing coupling RC is effective only for a change in the last stage N from normal to reverse, an external control such as a synchronizing pulse is required to shunt stepping pulses from the input associated with the transistor TR2. Alternatively, a second reversing coupling between the stage N and the stage 1 may be provided. In a modification (Fig. 3, not shown) a transistor is provided in each of the shunt paths P1, P2.

A billet transfer apparatus comprises billet holding means 20 rotatable about an axis Y-Y and also movable from a billet receiving station to a billet discharge station. In the extrusion of tubes, metal billets B 2 , which may be solid or have small drilled bores, are placed in the container 102 of a piercing press, compacted by an outer ram 10 and pierced by an inner stem 8. A retractable stem 14 permits disposal of the waste metal. Containers 2, 102 are mounted on a rotary turret 4 which moves the pierced billets B 1  to an ejection station where they are discharged by ejection means 16 into the holding means 20. This comprises an open trough into which the billets are clamped by member 22 operated by a fluid motor 24 and which is mounted on a shaft 28 rotatable in a horizontal cantilever arm 26. The latter is rotatable about a vertical axis X-X in either direction by rotary hydraulic motors 46, 48 for transferring the billet to a horizontal roller conveyer 18 on to which it is pushed by fluid operated means 64. During its transfer the billet is turned through 90 in either direction about axis Y-Y by a fluid motor 36. Pre-drilled billets are preferably turned in the opposite direction to the initially solid billets. The conveyer 18 moves the billets to the extrusion press. In other embodiments, Figs. 4-8 (not shown) the rotation of shaft 28 about axis Y-Y is derived through bevel gearing from the rotation of the arm 26 about axis X-X.

In Fig. 1, the tool consists of a body portion 2 having curved top edge surface provided with grooves 8 and a handle portion 4. The bottom edge surface 10 of the 'body portion is provided with a recess 12. The tool is provided with a series of grooves 14 in its major front and back faces, alternate grooves emanating from a common point in the recess, the other grooves being shorter and located adjacent top edge 6 giving a scalloped effect. The end of the body portion 2 opposite the handle portion 4 is provided, Fig. 2 (not shown), with extension 20 having a notch 22 forming a lead-in to the groove 8. The handle portion 4 has a notch 26 at 90 degrees to notch 22. In using the tool, an end of the yarn is secured in notch 22 and extended across the face 16 of the body portion and hooked around the handle by notch 26. The yarn is then extended behind and under the body into recess 12, brought up and around the body portion in the grooves 14 nearest the handle, and successive turns are wound, spaced according to the grooves. After several layers have been wound the yarn is cut behind the handle and the ends of the now separated piece extending across the front of the tool are brought together and knitted. The turns of yarn are cut along groove 8 to free the yarn from the tool, thereby producing a pompon. Multi-coloured yarn or several short sections of differently coloured yarn may be used. The pompon may be used to make ornamental articles, dolls or accessories for clothing, and may be attached to a wire frame.
