Title: Improvements in or relating to Disk Brakes.
IPC: F16D55/00
Filed: 1966-07-08
Abstract: 1,154,578. Disc brakes. DAYTON STEEL FOUNDRY CO. 8 July, 1966 [8 July, 19651, No. 30895/66. Heading F2E. In a disc brake assembly, torque receiving means in the form of a pair of pins 18 support at least one brake pad backing plate 21 on a pair of spaced torque transmitting supports 30, 31 provided on the backing plates, the supports being offset forwardly towards the friction pad face surface to engage the torque-receiving means at locations which are disposed closer to the plane including the pad face surface 36 than the plane including the rearmost surface of the pad thereby reducing the resulting moment arm between the pad face surface and the torque transmitting locations. The backing plate 21 is provided with an outer (23) and an inner (24) radially spaced ribs and is formed as a shallow receptacle for a portion of the brake friction pad 22 such that the offset torque transmitting supports 30, 31 on the backing plate 21 are spaced a distance t from the face 36 of the friction pad. It is stated that the above arrangement prevents uneven brake friction pad wear by substantially eliminating the unbalanced moment as the pad contacts the brake disc 13. Instead of being applied to a fixed caliper type disc brake the invention may be applied to a floating caliper type of disc brake (Figs. 6-9, not shown) wherein the extensions from the backing plate are provided with a pair of stub pins which define the torque-transmitting supports, the pins being supported in openings in the fixed support.
Patent GB-396686-A (GB)
Title: Improvements in means for actuating pyrophoric lighters and gas lighters
IPC: F23Q2/08
Filed: 1931-11-07
Abstract: 396,686. Frictional igniters. KELLERMANN GES., DR. H., 6, Ruschestrasse, Lichtenberg, Berlin. Nov. 7, 1931, No. 30911. Convention date, Nov..14, 1930. Void. [Published under Sect. 91 of the Acts]. [Class 75 (iii).] In a frictional igniter with a displaceable coupling disc with some play situated within the sparking wheel rim, the coupling disc 7 is arranged between two discs 17, 18 connected with one another, and just fitting into the sparking wheel rim 1, the discs 17, 18 being rotatable but not radially displaceable on the central pivot 8, and having eccentric oblong holes 21 corresponding in shape to a central oblong hole 9 in the coupling disc. A pin 15 which is connected with the actuating part of the lighter passes through the holes 21 in the outer discs 17, 18, and through a hole 14 in the disc 7. One half of the circumference of the disc 7 is formed with teeth 10, corresponding to teeth 6 on the whole of the inner surface of the rim 1. The disc 7 also has a recess 12 with a projection 13 which can engage with the bridge 19 connecting the two discs 17, 18. When fitted in a pocket lighter, the actuating member is the cover 16 which is pivoted on the axle 8 and carries the pin 15. The action is stated to be as follows :-The opening of the cover 16 causes the pin 15 to pivot the disc 7 about the projection 13 which is engaged by the bridge 19 and move it radially with respect to the axle 8, bringing the teeth 10 into engagement with the teeth 6 of the rim. Further movement of the pin 15 causes it to reach the ends of the slots 21, and the discs 7, 18, 19 and the rim 1 then move together, causing the production of sparks by friction of the rim 1 with a spring-pressed pyrophoric pin 3. When the cap is closed, the reverse motion takes place and the disc 7 is disengaged from the rim 1, which is held stationary by friction of the pin 3. The cap 16 has a part pivoted to it which is connected by a spring to the wick cap, which is pivoted to the supports carrying the axle 8. In a gas lighter, the axle 8 is mounted on a rod attached to a handle, and the pin 15 is mounted on a rod which can be moved in a direction parallel to the first rod by a trigger against a spring. A pin is pressed against the outside of the rim 1. The action when the trigger is pulled and released, and the second rod moves backwards and forwards, is as before.

Title: Apparatus for reading information magnetically recorded on a record medium
IPC: G11B11/10
Filed: 1960-09-08
Abstract: 883,936. Sensing statistical records; digital data-storage apparatus. NATIONAL CASH REGISTER CO. Sept. 8, 1960 [Sept. 25, 1959], No. 30964/60. Class 106 (1). Magnetically recorded data is read by directing a beam of polarized light on to the record surface, moving the record relative to the beam and detecting changes in the polarization of the reflected or transmitted light. The invention uses the Kerr magneto-optical effect whereby the plane of polarization of light is altered upon reflection from a magnetized surface or the Faraday effect by which the plane of polarization is rotated as it passes through a magnetic field. In the form of Fig. 1, the record consists  of a glass disc 10 having a thin film of silver on which is deposited a film of ferromagnetic material. This is covered with a dielectric film such as silicon monoxide which increases the magneto-optical effect by providing a smooth mirror-like surface. Data is recorded in a track 19 by a head 12. Light from an arc lamp 14 is passed through a small aperture 15, a polarizer 17 and focused by a lens 18 on to the track 19. Reflected light is received by lens 20 and directed through a polarized detector 21 to a photo-cell 22. The detector 21 is oriented to transmit only light which has been rotated by positive magnetization of the record corresponding, for example, to a recorded " 1." The " 0 " bit produces a comparatively small output in photo-cell 22. These outputs are amplified at 23 and clipped at 24 to obtain twostate signals. In using the Faraday effect, infra-red light is polarized and transmitted normally through a translucent tape having a very thin film of magnetic material. Changes in polarization are detected in the same way as before. Other radiations may be used.
