Title: Improvements in or relating to methods of inserting electrical components into apertures in mounting plates and to machines for carrying out such methods
IPC: H05K13/04
Filed: 1962-11-30
Abstract: 955,240. Assembling electrical components on mounting plates. PHILIPS ELECTRICAL INDUSTRIES Ltd. Nov. 30, 1962 [Dec. 4, 1961], No. 45391/62. Heading B3A. A method of inserting an electrical component e.g. resistor, capacitor, or the like provided with at least one resilient projection into an aperture in a mounting plate, comprises gripping the body of the component in a gripping device and holding the projection over part of its length against a supporting surface on said device, the gripping of said body causing a deflection of the projection such that it is pressed by its resilience against said supporting surface. A machine for carrying out the method comprises an abutment 5 having a wire receiving groove 6 and an anvil 7 with which a knife 8 coacts, a housing 9 in which a fixed jaw 10 is slidable and to which a jaw 20 is pivoted at 22 and a thrust rod 16 slidable in the housing and engageable with the jaw 20. The fixed jaw 10 has a narrowed end 12 in which wire receiving V-sectioned grooves 13, 14 are formed and above which is formed a cavity 15, the jaw 20 having a similar cavity and a groove 26. The jaw 20 is urged towards the fixed jaw 10 by a compression spring 24. In operation, resistors having wire ends 2, 3 and which may be connected to a band 4 are fed to the block 5, the fixed jaw 10 slides downwardly to support the resistor and the jaw 20 slides along and off the end of the rod 16 to allow the spring 24 to pull the jaw 20 against the resistor and tilt it in the cavity 15 thereby deflecting the wires 2 and 3 into the grooves 13, 14. Subsequently the ends of the wires are cut-off by a knife 8 to produce a sharp point on each wire projecting below the end of the fixed jaw 10 and the housing is displaced horizontally above a mounting plate 28. The jaws and rod 16 descend to insert the wires into apertures 27 in the plate 28, a recess in the end of the rod engaging the upper curved portion of the wire 2, and as the rod pushes the wire fully home an inclined face 19 thereon engages a coacting face 23 on the jaws 20 to disengage the jaws from the resistor prior to their subsequently retraction. The movements may be controlled by cam or pneumatic means. Various modifications may include, moving the housing, pivoting the jaw 20 away from the fixed jaw, replacing the cavity in the fixed jaw 10 by two abutments adapted to engage the upper and lower ends of the resistor and that in the jaw 20 by a central abutment, pre-cutting the wire ends to length and allowing axial movement of the resistor in the jaws so that wire not initially extending beyond the fixed jaw is advanced by the thrust rod therefrom.

Abstract: 1,164,717. Disc brakes. ALFRED TEVES G.m.b.H. 5 Oct., 1967 [28 Dec., 1966], No. 45527/67. Headings F2E and F2F. A parking brake for a fixed-caliper disc brake comprises a pair of pads 5a, 5b on opposite sides of the disc 1, the pads being deflected towards one another by thrust from a mechanical coupling (e.g. a Bowden cable 6) acting in a direction parallel to the axis of the disc 1. As shown in Fig. 3, the pads 5a, 5b are auxiliary to the main pads (Fig. 4, not shown), pad 5a being operated mechanically by the thrust of a Bowden cable 6 on a bridge piece 7 whilst pad 5b is actuated hydraulically by the action of the bridge piece 7 via a member 10 on the piston 11 of an auxiliary master cylinder 12 coupled to a slave cylinder 14 via a port 13. In Fig. 9, the parking brake utilizes the main pads 47a, 47b acting on a disc 36; the pistons 33a, 33b of the main cylinders are cup-shaped so as to receive the parking brake pistons 32a, 32b actuated by a master cylinder 40, the piston 39 of which is controlled from the hand brake by thrust of a Bowden cable 38. In Fig. 6 (not shown) two auxiliary slave cylinders receive pressure from an auxiliary hand brake-controlled master cylinder and actuate respective auxiliary pads.

Abstract: 1431964 Automatic control of cutting SCHUBERT & SALZER MASCHINENFABRIK AG 28 Sept 1973 [30 Sept 1972] 45538/73 Heading G3N In the cutting of sheet material in which a pattern follower device (140), Fig. 7 (not shown) follows an edge on a master pattern and corresponding motion is imparted to a tool cutting the sheet material, the device (140) follows a single endless line from and to a start/stop surface 10 on a master pattern 1, the line encompassing model surfaces {horizontal hatching }representing parts to be made up {e.g. into trousers } . The diagonal hatched surfaces representing connecting surfaces may be provided to ensure continuity of the line. The master pattern may comprise model surfaces contiguous at a corner, the scanning line being without kinks in passing from one surface to the other, though intersecting itself, Fig. 6 (not shown), the tracing head being able to trace sharp corners in either left, or right hand sense, or the control, and master pattern configuration may be such that only kinks requiring, e.g. a right hand turn of the scanning device can be followed, left hand turns being progressive, Fig. 1. The pattern may be made up in paper, cardboard, or plastics on a horizontal magnetic table, Fig. 8 (not shown) the pattern pieces held in place by magnets, the model surfaces being inter-connected by connecting pieces (e.g. 82) Fig. 5 (not shown) and resilient strips (e.g. 98) which may be adhesive, to form the endless line, the table being tilted to the vertical in order to make a photographed transparency of it used later for tracing, or to enable tracing of the pattern. Tracing head & circuitry, (Fig. 7) The head device rotatable about axis (142) has an optical head (141) and tracing normally takes place with the latter on the line see (Fig. 6). Should it leave the line, e.g. at a corner, units (150, 151) activate relay (152) after a delay, switching control from head (141) to set of auxiliary heads (143- 146) coupled to electronic modules (170-184). For all possibilities of one, resp two, three, or four of the auxiliary heads illuminated at this time, the device (140) is rotated in right or left senses, or moves ahead according to a disclosed logic scheme until head (141) is again on the line, whence control reverts to the latter, right or left hand corners of the line thus being traversible. The need for a continuous line at all points where it intersects itself can be obviated if the connections to the electronic modules are altered, enabling kinks in one sense only to be traversed and requiring a master pattern of the Fig. 1 type. Alternatively, there may be two or eight auxiliary heads. Tracing may be electro-inductive. In (Fig. 5) traced in the manner of (Fig. 6), connecting surface (68), whose boundary is fabricated from strips and connecting elements at the external corners of model surface (60, 62, 64-67), is provided. Outputs from the electronic modules may be used to inhibit cutting by the tool until the tracing device is on the line.

Title: Method and Apparatus for Cross-Laying Threads
IPC: D04H3/04
Filed: 1966-10-18
Abstract: 1,169,215. Laminates comprising threads. JOHNSON & JOHNSON. 18 Oct., 1966 [21 Oct., 1965], No. 46566/66. Heading B5N. [Also in Divisions B8 and D1] Threads are laid in a transverse direction by an apparatus comprising two pairs of endless diverging surfaces (e.g. chains 43) having carrier bars 60 mounted between each pair. Interengageable elements (e.g. hooks and eyes 63, 64) mounted on the carrier bars 60 on each of the diverging surfaces in horizontally aligned pairs are arranged to meet at a common point and encircle a thread supplied by a means (not shown) to the point. As the chains diverge the thread is advanced and laid in a transverse path. The thread, when fully extended between the outermost reaches of the diverging paths is gripped and conveyed away (e.g. by a pin belt conveyer 71, 72) and is released from the interengageable elements 63, 64. The pin belt conveyer 71, 72 preferably conveys the transversely laid thread to a horizontally moving carrier (88) (see Fig. 1, not shown). As shown in Fig. 5 the hooks 63 are mounted on a vertical rod 61 that can slide within stationary shell 45. Shell 45 carries the eyes 64. In operation the hooks and eyes are closed around the thread by a cam bar (70) pushing upwardly on wheel 67. See also Fig. 3, not shown. As the conveyer shell 45 approaches point C the hooks and eyes are opened. Wheel 83 of the conveyer then actuates a pin belt guide 80 so as to open its guide loops (77) (see Fig. 6, not shown). The hooks 63 then deposit the crosslaid thread on pins 81 of the pin belt conveyer. The pin belt guide 80, having as many loops (77) as there are hooks 63, is carried on a vertical rod 78. Rod 78 is moved upwardly to open loops (77) by a cam (82) at its lower end acting on the approaching wheel 83. The thread can be laid in a parallel manner, as shown, at 90 degrees to the pin belt conveyer or in a zig-zag manner The term " thread " means strands, yarns, cords or filaments. The threads can be made of synthetic fibres, cotton, paper yarns or continuous filaments. The threads may be laminated between two pieces of paper or non-woven fabrics.

Title: A Line Spool Braking Device for Fishing Reels.
IPC: A01K89/0155
Filed: 1967-10-12
Abstract: 1,178,448. Brakes. ABU A.B. 12 Oct., 1967 [25 Oct., 1966], No. 46580/67. Heading F2E. [Also in Division A1] In a fishing reel consisting of a spool 8 secured to a spindle 4 which is mounted in ball bearings, the spool has a brake which acts by a combination of friotional drag on one end of the spindle and bearing drag produced by applying axial thrust to the bearings. The preferably resilient friction pad 22 can be moved by rotation of a clamping nut 19 from the initial position shown into contact with the spindle end 18 and such movement increases the force applied by a spring 16 to a pressure member 15 engaged with the rotatively fixed but axially displaceable race 11 of the adjacent ball bearing. This axial thrust on the bearing is transmitted by the spindle to the bearing at the other end. The bearing drag thus produced has a braking effect which increases with speed of rotation, whereas the frictional brake on the shaft end has an effect which reduces with speed. It is thus possible to adjust the position of the friction pad (whose effect is much more dependent on axial loading than is the effect of the bearing brake) to achieve an appropriate combination of the two different types of braking.
