Title: Improvements in disc brakes
IPC: F16D55/228
Filed: 1952-11-11
Abstract: 747,965. Disc brakes. DUNLOP RUBBER CO., Ltd., and BUTLER, H. J. Oct. 20, 1953 [Nov. 11, 1952], No. 28333/52. Class 103 (1). In a spot-type disc brake, of the kind described in Specification 688,382, in order to prevent heat from the friction elements 22 being transmitted to the hydraulic fluid and leathers in the actuator cylinders 13 on each side of the single disc 1, the cylinders are spaced away from the caliper member 11. As seen in Fig. 1, the plungers 17 act through distance pieces 19 of heat insulating material upon members 20 against the spherical end faces of which pivot backing- plates 23 for the friction pads 22. Annular rubber shields 21 prevent entry of dirt or fluid into the cylinders. The cylinders are secured to caliper members 11 by bolts 14, as shown in Figs. 2 and 3, having springs 16 which allow some degree of axial movement to provide for temperature effects. In Fig. 5, a disc brake according to the invention is shown, which is suitable for use on a heavy commercial vehicle, and which incorporates automatic clearance adjusters 44 of the kind described in Specification 747,972. Specification 712,534 also is referred to.

Title: A control system for the speed of driving motors of rail vehicles
IPC: B60L50/11
Filed: 1961-08-04
Abstract: 989, 067. Automatic control of speed. ELEKTRO-MECHANIK G.m.b.H. Aug. 4, 1961 [Aug. 4, 1960], No. 28406/61. Heading G3R. [Also in Division H2] Relates to a follow-up control system for determining the speed of a driving motor of a rail vehicle, the power input to the driving motor being controlled by a pilot motor 26. When relay 16 for the first traction stage is energized by adjustment of controller 21, voltage dividers 10, 11, are connected to polarized relays 24, 25, and relay 24 responds to actuate contactor 27. The pilot motor 26 is then switched-on to increase the speed of the vehicle, and adjusts voltage divider 30 until the relay 24 is released. Further acceleration is afforded by adjusting the controller 21 to energize relays 17-20 in sequence. The switching-on of the pilot motor 26 in the direction for downward regulation of speed is effected in a similar manner through voltage divider 11 and polarized relay 25. In another arrangement, relays 31-35 are operated in succession to increase the speed of the drive motor, and are successively de-energized to reduce the speed. Resistors 37-41 serve for the acceleration operation, whilst resistors 42-46 are effective during the deceleration period. Thus, in the first traction stage, relay 31 responds to complete a circuit for relay 48 through resistor 37 and voltage divider 52. The pilot motor 47 increases the speed of the vehicle and adjusts the divider 52 until relay 48 is released. In a further embodiment the actual speed detector is a tachometer generator coupled to the main driving motor, Fig. 3 (not shown). The main driving motor may be electric or non-electric.

Abstract: 985,754. Foot-arch supports. LABORATORIES FOR APPLIED BIOLOGY, and J. G. MACDONALD. Nov. 2, 1962 [Aug. 4, 1961], No. 28484/61. Heading A3B. A foot arch support comprises a flexible pad to which is secured at least one arch support unit comprising a strip of nominally bendable ductile metal bent to arch form and held in that form by a tension member hooked to the ends of the strip. As shown, Fig 1, the pad is of foam rubber and two aluminium strips 11 are arranged between the pad and a bottom cover which is glued to the pad. A third aluminium strip 16 to support the metatarsal arch is arranged between the pad and a flexible rubber flap 12 which replaces a portion of the bottom cover. Markings 17, 18 indicate lines of cut for different sizes, and markings 19, 20 indicate the positions of strips 11. Strips 11 are bent to shape. Two strips 11 permit the support to be used with right- or left-hand shoes, or to support the lateral and medial arches. Strips 11, 16 are held to their bridged shapes by tension springs 21, e.g. elastic, which hook on to the two ends of the bridges. In a further embodiment the support stretches from the heel to the metatarsals, and two aluminium strips lie at an angle to the sides of the support and are attached to the pad by a sheet of woven fabric or a foam rubber sheet which is covered on its lower side with woven fabric. In a further example the pad is covered on its upper side with perforated woven fabric and two perforated aluminium strips are attached to the lower side by sticky tape. In the construction shown in Fig. 7 the arch support member comprises an aluminium strip 38 with a foam rubber strip 40 which are bent to shape and held in arched form by a second aluminium strip 39 hooked around the ends. These support members are stored flat, i.e. with strips 38, 39 parallel. The pad may be covered with flexible plastic so as to form pockets which hold the strips, or pockets may be formed by glueing together two leather sheets. Additional supports, e.g. a ring of felt, may be attached to the pads.

Title: Method and apparatus of controlling exposure times in photographic  printers
IPC: G03B27/80
Filed: 1970-06-15
Abstract: 1317607 Exposure control of photographic printers CIBA-GEIGY AG 15 June 1970 [16 June 1969 and 24 April 1970] 28978/70 Heading G2A An original 9 is printed on to print material 12 by an exposure which is controlled by a reference original 9R. The reference original is initially placed in the printing apparatus and a part of the beam transmitted therethrough from a source 10 is incident upon a photo-cell 1 to generate a corresponding electric signal which is fed through an amplifier 2, a logarithmic element 6 and coupled to one side of a potentiometer 3. The other side of the potentiometer is coupled to an adjustable reference signal U 2  produced by rheostat 8 and voltage source 7, rheostat 8 being adjusted so that the signals on both sides of the potentiometer are equal. The reference original is then replaced with an original from which prints are required to produce an output signal U 3  at the potentiometer tap which is integrated by capacitor 4. When the integrated control signal reaches a valve determined by comparitor 5, the exposure is terminated by a shutter 13. The position of potentiometer tap 14 is set according to the characteristics of the original and print material. A modified arrangement is described in which the potentiometer 3 is replaced by two potentiometers, one potentiometer being connected in series with a diode, the series combination being connected in parallel with a further series combination of a potentiometer and a diode, the diodes being oppositely poled. Reference signal U 2  is applied to the junction of the diodes, the logarithmic signal is applied to the junction of the potentiometers, and the two taps are connected together. This arrangement gives different control characteristics for over-and under-exposed originals.
