Title: Improvements in or relating to handbrake mechanisms
IPC: B60T11/08
Filed: 1966-04-14
Abstract: 1,102,308. Handbrake mechanism. H. O. SCHRÍTER. 14 April, 1966 [15 April, 1965], No. 16378/66. Heading F2E. In handbrake mechanism of the kind in which a flexible or articulated tension element connects a handbrake lever with a guide member mounted on a support associated with or carrying the lever pivot, the arrangement being such that the line of action of the tension elements moves progressively nearer the pivot to increase the leverage up to a maximum value when the tension element abuts the pivot, additional guide means is provided for the tension element on the handbrake lever such that the tension element extends in a curved path between its anchorage on the handbrake lever and the guide member. A formula equating the integral of the work done in moving the handbrake lever with a substantially constant force with the integral of the work done by the tension element in overcoming elastic deformation of the brake linkage after engagement of the brake shoes is given as a basis for calculating the form of the curved path. In the embodiment shown, this curved path is determined approximately by two, preferably adjustable, abutments 5 on the handbrake lever 1 which are suitably located in relation to the anchorage point 3 of chain 2 on the lever and an anchorage 7 on a guide lever 8 pivoted at 11 to a support 12 which carries the handbrake lever pivot shaft 4, such that after engagement of the brake shoes the leverage produced increases substantially linearly with travel of the handbrake lever until the chain engages the pivot shaft 4, which corresponds to maximum leverage. In a second embodiment (Fig. 2, not shown) the tension element is a cable which passes through a guide member (10) against which a sheath (9), through which the cable passes to the brake-applying mechanism, abuts, while the additional guide means is a member (13) provided with a curved guide (6) pivoted to the handbrake lever at (14), the member (13) being adjustable by a screw (15) on the handbrake lever to vary the distance between the free end of the guide (6) and the pivot shaft (4).

Title: Improvements in the production of bent tubes
IPC: B21D7/06
Filed: 1941-12-19
Abstract: 549,280. Bending tubes. BLACKBURN AIRCRAFf, Ltd., and NIVISON, D. B. Dec. 19, 1941, No. 16422. [Class 83 (iv)] In bending tubes, the tube is first bent in one plane between a pair of dies or by relative movement with respect to a die and bending is then effected in another plane at an angle to the first by a die moving relatively to the initial bending die or dies. The initial bending may be effected as described in Specification 543,362 or may be effected by a pair of dies 1, 2 movable on guides with respect to each other. The dies, which may be of wood, are provided with inserts 3 of a hard wearing material. The tube is placed on ledges 6 on the die 2, which is also provided with end pieces 14 so that when the dies are closed to effect the initial bend a gap is left between the surfaces which is slightly larger than the diameter of the tube. The dies are then locked together by hooks 12 and pins 13 and the tube bent in another plane by a die 10 cooperating with a shaped ledge 7 on the die 1. The die 10 is provided with guide rails 9 moving in guideways 8 in the die 1 and has shaping elements 11 entering the gap between the dies 1 and 2. Bending may be effected between the platens of a press, the assembled die unit after the first bend being turned through 90 degrees prior to effecting the second bend. In order to avoid adjustment of the press between the first and second operation the distances between the outer ends of the dies 1, 2 in the closed position and between the outer end of the die 10 and the base of the dies 1, 2 in the closed position are made equal to each other. The tube may be filled with a medium inserted and removed therefrom in a heated liquid state and the tube or dies or both may be greased during bending.

Title: Multiple-point recorders
IPC: G01D9/30
Filed: 1964-04-23
Abstract: 1,015,476. Recording-apparatus. LEEDS & NORTHRUP CO. April 23,1964 [May 6, 1963], No. 16921/64. Heading G1V. A multipoint recorder comprises a carriage 16 guided on a rod 86 for movement across a chart 18 in accordance with the values of variables to be recorded, a rotating cam 19 periodically rocking about an axis 13, an arm 12 carrying a print wheel 10 which, in the interval between successive printings, is rotated to bring a new marker opposite the chart by a gear train synchronized with the rotation of the cam 19 and a spring 77 which is stressed while the cam 19 rocks the arm 12 away from its neutral position and subsequently restores the arm 12 whose over-travel carries the print wheel 10 against the chart 18. The spring 77 interconnects the ends of arms 76A, 76B which are freely rotatable about the axis 13 and embrace the shaft 11 of the wheel 10 and a stop 78 adjustable on an arm 66 of a yoke 15. The print wheel 10 may be impregnated with ink or it may be inked upon each upward movement of the arm 12 by an inking wheel rotatable on the arm 66 in synchronism with the wheel 10. The inking wheel may comprise a plurality of pads of different colours. A continuously rotating elongated pinion 45 drives the gear train for the cam 19 and wheel 10. Part of the train to the wheel 10 is supported on the arm 12 so that rocking the arm 12 introduces a differential gear action which is arranged to minimize rotation of the wheel 10 during printing and by allowing sufficient back-lash the drive can be temporarily interrupted by frictional engagement of the wheel 10 against an axial thrust bearing. The peripheral face of the wheel 10 has a set of dot-markers and a set of corresponding pointidentification markers, when it is parallel to the print line A-A both markers can print, when inclined only the dot-marker. Selectively to provide for either, the axle 13A of the arm 12 is supported in the yoke 15 which is pivotable about an axis 17 on the carriage 16 and urged by a spring 22 to hold an anti-function roller 24 against a tilt-bar 23. A selector 34 may be provided and set for an arm 27 to engage one of three pins 35, 36, 37 and so angularly position bar 23 that both marks will be printed every time, dots only will be printed or printing will be inhibited by a pawl 38 moving the arm 12 out of range of the cam 19. With the selector 34 omitted or disabled printing can be inhibited by energizing a solenoid 40 and tilting of the yoke 15 can be controlled by a cam 29 through a follower 31. By suitably timing rotation of the cam 29 relative to rotation of the wheel 10 identification marks can be printed at suitable intervals with dots only in between. The elongated pinion 45 passes through a nylon bearing on a stud upstanding from the carriage 16 to serve as a second guide bar. Multi-way switches are provided for cyclically connecting the variables to a selfbalancing measuring circuit controlling movement of the carriage 16 in timed relation with the printing operations.

Abstract: 1468406 Photoelectric distance measuring SIEMENS AG 19 April 1974 [17 May 1973] 17173/74 Addition to 1432801 Heading H4D In a modification of the photoelectric distance measuring system described in Specification 1,432,801, the beam deflector system 3, Fig. 1, is driven by a sinusoidal control voltage having a frequency matching the natural resonance frequency of the deflector system, only the substantially linear portions, e.g. 120 to 240 degrees, Fig. 2, of the sinusoidal waveform being used in the measurement. The sinusoidal output of generator 1 is phase shifted by 120 degrees at 15 and converted to a 120 degree indicative pulse 18, via squaring circuit 16 and differentiator 17. This "start of scan" pulse is fed to one input of discriminator 14, having a pulse 21 derived from the output of detector 10, detecting the striking of object 9 by the beam, fed to its other input, to give a distance to object indication at 19. A semitransparent reflector plate 24, at a reference distance 23 from the deflector, causes a reference detector 25 to receive a reflection of the beam when the sinusoidal waveform is just beyond 120 degrees. The detector output is converted into a pulse at time T B  by means 27, 28 and fed to discriminator 29 together with 120 degrees indicative pulse 18 at time T REF . The discriminator produces a pulse of duration (T B -T REF ) and this is duration compared at 33 with a standard duration pulse 32 from flipflop 31 triggered by 120 degree pulse 18. The comparison gives correction signals which, for coarse correction, control a motor drive potentiometer 37 to vary the frequency of oscillator 1, and, for fine correction, control the phase of the oscillator output.
