Title: Improvements relating to disc brakes
Inventor: REDMAYNE LEONARD
IPC: F16D65/18
Filed: 1957-11-19
Abstract: 907,715. Disc brakes. GIRLING Ltd. Nov. 18, 1958 [Nov. 19, 1957], No. 35951/57. Class 103 (1). In a spot-type disc brake the hydraulic cylinders 15 are inclined at a small angle to the axis of the brake disc 11 and the caliper housing 10 is mounted in such a position that the outer ends of the cylinders are at a higher level than their inner ends so that air in the system will accumulate at the outer ends of the cylinders from which it can be removed through bleed passage 16 and bleed nipple 17. Instead of the caliper housing being formed as a single casting, as shown, it may be formed in two halves bolted or otherwise secured together, the division being substantially in the central plane of the disc. The friction pads 12 are bonded to steel backing plates 13 which are guided in the caliper for movement towards and away from the disc and the abutments for the backing plates which take the braking torque are parallel to the axis of the disc. A flexible bellows seal 19 is provided between each piston and the inner end of its associated cylinder as shown in Fig. 2. Specifications 742,338 and 801,805 are referred to.

Title: Antiskid braking system for wheeled vehicles
IPC: B60T8/172
Filed: 1974-08-21
Abstract: 1484274 Aritiskid braking system KYODO ELECTRONIC LABORATORIES Inc 21 Aug 1974 [14 Sept 1973 25 April 1974 28 May 1974] 36791/74 Heading F2F In an antiskid braking system a first voltage signal proportional to wheel speed is provided, of which signal the peak values are stored and compared with the present signal value so that when the wheel speed decreases by more than a predetermined percentage from a peak a further signal is generated to modulate braking pressure by means of a control valve 2. A wheel speed detector 1 supplies a signal to a velocity-to-voltage converter 4 connected to a peak memory circuit 5 and a speed decrease comparator 7 connected in turn to the memory 5 and having its output connected by means of an AND circuit 14 to a valve driver circuit 3. Circuit 4 is also connected to a speed increase comparator 6, which is connected to the output of memory 5, and to a comparator circuit 9 and differentiator circuit 10 receiving a reference voltage from a source 8, the output of circuit 10 being connected to a deceleration comparator 13 receiving a signal from wheel deceleration source via a circuit 11 which can discriminate road conditions as to whether the surface is asphalt or ice for example. The circuit 13 is arranged to determine whether or not an anomalous deceleration has occurred, its output being supplied to the AND circuit 14. A valve timer circuit 15 operates as a fail-safe circuit to limit the maximum time of the valve 2 being open.  In a modification, Fig. 2, a wheel speed sensor 101 supplies a signal to a frequencyvoltage converter 103 via a waveform shaper 102 and the output passes to a directional change over circuit 104 grounded by a capacitor 105 and connected to charge and discharge circuits 107, 106 which have rates corresponding to a predetermined acceleration G 2  and a deceleration G 1 . Divider circuits DV 1 , DV 2  set up references to be compared with the signal waveform and a latch circuit 112 provides at the output thereof a control signal which is transmitted to the solenoid 113 of the brake control valve. An inhibit timer 116 prevents erroneous operation due to noise spikes from the wheel speed signal.

Title: Improvements in or relating to apparatus for handling articles
IPC: C03B19/10
Filed: 1958-11-20
Abstract: 903,671. Removal of glass articles or cullet. COMPAGNIE DE SAINT-GOBAIN. Nov. 20, 1958 [Nov. 20, 1957], No. 37439/58. Class 56. [Also in Group XXX] Discarded parisons or other articles are discharged from a trough 1 (Fig. 9) by a shovel 5 rotating about a shaft 9 but capable of adopting different attitudes to the bottom of the trough. In the form shown, the shovel 5 pivots about an axis 21 on brackets 15 carried by the shaft 9 and is biased by a spring-urged stop 26 so that a roller 8 on it is pressed into engagement with the trough. When the roller 8 reaches a cut-out 29 (Fig. 11) in the trough the shovel 5 falls under gravity to the discharge position of that figure. As rotation of the shaft 9 continues, a fixed stop 27 (Fig. 13) cams against an arm 22 on the shovel to tip it to a position from which it can again fall into engagement with the stop 26 in preparation for a further sweep. The rotation of the shaft 9 and the supply of water to the trough may be controlled in accordance with the arrival of the parisons by a contact thermometer measuring the temperature of the water in the trough.

Title: Internal Interpolator which Works Digitally for Numerical Path Controls
IPC: G06F17/17
Filed: 1967-08-16
Abstract: 1,193,110. Interpolators. LICENTIA PATENT - VERWALTUNGS - G.m.b.H. 16 Aug., 1967 [17 Aug., 1966], No. 37605/67. Heading G4A. A simple linear interpolator dispensing with the need for dividing circuitry is described. Assuming the starting point of a path to be interpolated has co-ordinates xa, ya and the end point of the path has co-ordinates xe, ye, a quantity (xe-xa) + (ye-ya) is first calculated. The output of the arithmetic unit for performing this calculation is applied in binary coded decimal form to a reference register (DR1) having only three binary stages (of 4, 2, 1 significance) per decade, the inputs and outputs of this register being so connected that only a single bit is registered and that at a position of next higher significance to the highest input bit. For example, an input corresponding to decimal 1100 would be registered as decimal 2000. Thus, all numbers in the range 1000-1999 would be registered as 2000, 2000-3999 as 4000 and 4000-49999 as 10000. Two adding registers SMX and SMY, after being initially zeorized, are then repetitively incremented by the quantities (xe-xa) and (ye-ya) respectively until either reaches or exceeds the quantity in the reference register, as determined by a simple AND gate comparison circuit. The quantity in the reference register is then subtracted from the total in the register SMX or SMY as the case may be, a signal for causing a unit step in the corresponding co-ordinate direction is generated and a register SWX or SWY for recording actual co-ordinate movements is incremented. The process then continues until the desired end point is reached. The interpolator may control a machine tool or a drawing machine. The invention is said to be applicable to circular interpolation.

Title: Improvements in or relating to typewriters
IPC: B41J19/58
Filed: 1963-09-27
Abstract: 995,806. Typewriters. INTERNATIONAL BUSINESS MACHINES CORPORATION. Sept. 27, 1963 [Oct. 1, 1962], No. 38088/63. Heading B6F. Type-wheel actions; type-head carriages; variable letter-spacing mechanism .-A typewriter is provided with a proportional spacing escapement mechanism which is connected to a reciprocatory type head carriage 44, Fig. 1, through a gear train mechanism 4 . . . 9 . . . 12, having an adjustable transmission ratio so that a unitary angular displacement of an output member 17, Fig. 3, of the escapement mechanism is converted into a displacement of the type-head carriage in accordance with the width of the type fonts on the interchangeable type head 43. The escapement mechanism (not shown) includes the shaft 17 which is angularly displaced, when a key is depressed, to move the carriage 44 a predetermined distance corresponding to the spacing interval assigned to the key. The angular displacement of the shaft is transmitted through gear 16 to a gear 15 fast with a hollow shaft 13 having a cylindrical element 19, whose pawl 23 engages selectively one of the gears 10, 11 or 12, mounted loosely on the shaft 13. When a basic type front head 43 is used the pawl 23 engages the gear 11, which when driven by the gear 15 rotates a gear 5 through an intermediate gear 8, to rotate in turn a lead screw 1 to displace the type head carriage in the letter-spacing direction. Movement of the carriage 44 is effected in the interval between depression of a key and the moment of impact of the type head 43. If the type head 43 is replaced by one whose type fonts have a greater width than the basic type fonts a lever 35 is shifted towards the keyboard to convert the basic spacing by displacing a bellcrank lever 30 in a clockwise rotation resulting in a corresponding axial movement of a lever 26, mounted on the element 19. The element 19 is thus moved axially and the pawl 23 engages the gear 10 meshing with a gear 4 through a gear 7 (Fig. 2, not shown) to impart rotation to the lead screw 1 by a value proportional to the width of the next character to be typed. If the type head 43 is replaced by one having a type font width less than the basic type font, then by rotating the lever to the rear of the keyboard, the lever 26 is positioned to determine a linkage including gear-wheels 16, 15, 12, 9 and 6. The arm of the lever 35 is also connected to a link 45 which through a bell-crank 46 operates a rotatable index shaft designed to co-operate with a pointer 47 fixed to the type head carriage 44 to indicate the spacing scale chosen.
