[Also in Division F1] An autocycle transmission arrangement comprises a shaft 11 rigid with which is a pair of pedal cranks and upon which is rotatably mounted a chain sprocket 17 connected by a chain 25 with a sprocket 26 integral with a shaft 16; the auxiliary motor 1 having an expanding pulley 2 centrifugally operated by a series of balls 3 and connected by a driving band 4 to a spring-actuated pulley 5, forming an automatic change-speed device driving a shaft 6 rigid with which is a pinion 27 in permanent mesh with a gear 28 rotatably mounted on the shaft 16 upon which is also rotatably mounted an output pinion 29 connected by a chain 30 to a sprocket 31 driving the rear wheel. The pedal crank-shaft 11 is rigid with a screw thread 19 upon which is threadedly mounted a collar 21 incorporating dog clutch elements 21 which may be brought into driving engagement with corresponding elements 22 on the pinion 17, the collar 21 being prevented from rotation by a spring 23 gripping the collar and entering a groove 24 in the supporting housing 9 so that the pedals may be brought into driving engagement with the shaft 16 by rotating them at a speed faster than that produced at the shaft 16 by the motor, e.g. when the latter is under load, or is stopped. The shaft 16 is hollow and incorporates a shaft 32 longitudinally slidable under the action of a fork 40 engaging a threaded member 41 rotatable by means of a pedal or lever, the shaft 32 having a raised portion 33 which co-operates with a ball series 36 and raised portions 34 and 35 which cooperate with a ball series 38, the ball series 36 and 38 being located in holes in the shaft 16 and in the raised position shown engaging grooves in the gear 28 and output sprocket 29 respectively to provide driving engagement between these elements and the shaft 16. The shaft 32 may be moved to the right of the position shown to a position whereby the balls 38 fall to a disengaged position between the portions 34 and 35 and the balls 36 are retained in the driving position by the portion 33, and still further to the right where the balls 38 are re-engaged in the driving position with the sprocket 29 by the portion 34, and the balls 36 fall into a disengaged position. By appropriate engagement or disengagement of the gear 28 and sprocket 29 with the shaft 16, the pedals may be used for solely driving the machine, for augmenting the motor effort, or, with the machine stationary, for driving the motor, e.g. to start it.

A method of forming a groove 84, 86, Fig. 4 (not shown), in the outer surface of a tubular workpiece, e.g. a wheel, supported on a mandrel 17 having a reduced end 68 comprises pressing a conical plug 21, Fig. 3 (not shown), against the end of the work while rotating the work relatively to a forming tool 74 which presses the work against the reduced end of the mandrel. In a preliminary operation the work, located against a shoulder on the mandrel, Fig. 2 (not shown), is thinned and elongated from the original form 65 by a forming roll 50. After forming the groove (Fig. 4) it is given a radial wall, Fig. 5 (not shown), by a further radially and axially movable roll 88. The wall is then trimmed, forming an edge 96. Apparatus, Fig. 1 (not shown), for spinning the work is similar to that described in Specification 889,077 and includes a headstock 15 supporting and rotating the mandrel and a tailstock 14 movable by an hydraulic cylinder 23 for applying the plug 21 against the work. The roll 50 for thinning the work is mounted on a cross-slide 43 carried by a saddle 38. An hydraulic cylinder 45 for feeding the cross-slide 43 is controlled by a valve which is operated by a stylus 58 engaging a pattern 59. The saddle is traversed by a cylinder 40. The roll 74 for spinning the groove is also mounted on a saddle and a cross-slide controlled by a template 80. The finishing roll 88 is substituted for either of the rolls 50, 74 and is controlled by a feed-stop (not shown) or by a pattern.

Abstract: 1338105 Traverse mechanism A OTT 4 Oct 1971 [2 Oct 1970] 46116/71 Heading D1J A thread traversing mechanism that shortens the effective thread traverse as the thread package increases in diameter comprises a thread guide 7 that is rockable about an axis 6 passing substantially through its centre of gravity, means 1 for traversing the guide 7 back and forth, and further means responsive to package diameter for turning the front end of the guide 7 in a direction towards the centre of the traverse as the thread guide approaches each end of its stroke.  The thread guide 7 has an arm extending sideways therefrom and this arm carries a roller 10 running in a track 12 centrally pivoted at 13. As the package increases in diameter it causes the traversing mechanism to rock upwardly about the axis of the means 1, and a cam follower 20 carried by the track 12 follows a cam surface 22 in a manner causing the track 12 to swing gradually to the broken line setting.

Abstract: 1395667 Testing frequency response; sweep frequency generators SOC ITALIANA TELECOMUNTCAZIONI SIEMENS SpA 4 Oct 1973 [6 Oct 1972] 46369/73 Headings H4L H3R and H3T The triangular wave which controls a voltage controlled oscillator VCO to form a wobbulator is generated by a binary counter CN which alternately counts upwards and downwards between limits and which drives a digital to analogue converter ADC. The limits are set by potentiometers P1, P2 whose outputs are compared with the ADC triangular output to set and reset a bi-stable B as the first and second limits are respectively reached. Bistable B alternately enables gates N1, N2 to pass clock pulses from CK to the up and down inputs U, D of the counter. The clock source CK has a crystal oscillator O, dividers D 1 -D n , and a selector switch S to set the clock frequency and hence the sweep frequency for the VCO. The VCO consists of an integrator I which integrates the input voltage to a switch SW3 in a positive or negative sense according to whether SW3 is set to p or n. Comparators CM3, CM4 sense when the integrator output reaches respective limits set at R1 and R, and changes over a bi-stable B2 which in turn changes over SW3 to reverse the integration process. The input to SW3 may be one of the reference potentials from P1, P2 to give a corresponding frequency (this is for setting up the limits of a frequency sweep on meter F), and then be switched by SW1 to the ADC output whose triangular wave sweeps the VCO output between these frequency limits. A square wave may be taken off at Y, a triangular wave at the integrator output, or a sine wave from a filter SD whose cut-off frequency is arranged to vary with the output frequency.

[Also in Division F2] In a plug device, e.g. for securing a leg 23 to a tabletop 5, a nut 2 is secured in a plug 1 of compressible material such as wood. The device is secured in a hole 4 by applying a liquid-based cement or adhesive to the pre-compressed plug 1 or to the hole 4 and inserting the plug so that the liquid expands the plug to make a tight fit in the hole. A double-threaded screw 24 for attaching the leg 23 may be threaded first into the leg or the nut 2. A tool, Figs. 5-7 (not shown), for joining the nut 2 and plug 1 before use, has a tube with a flared mouth for driving over the plug to compress it to a smalled diameter and with an internal shoulder which drives prongs 3, which project from an end flange of the nut, into the plug while it is compressed. Any expansion caused by the entry of the prongs may be counteracted by a taper of the tube hole, from its internal shoulder to the smallest diameter at the inner end of the mouth flare. The plug is then slightly recompressed as it is pushed out of the tube through its mouth.
