Title: Disc brake caliper movement control
IPC: F16D55/2255
Filed: 1970-11-27
Abstract: 1293679 Spot-type disc brakes; retractors; slack-adjusters AIRHEART PRODUCTS Inc 27 Nov 1970 [8 Dec 1969] 56561/70 Heading F2E A spot-type disc brake including a caliper slidable on rods 50 fixed to a non-rotary torque arm structure 51, Fig. 1, has actuators 70, 71, for applying the directly-operated pads, disposed inwardly of the rods 50; retraction is by a Belleville spring on each rod, and slackadjusting is provided for by a drag ring frictionally gripping each rod, the friction being overcome to move the drag ring along the rod only when caliper movement becomes excessive as a result of wear. As shown, the brake assembly comprises the floating caliper 46 mounted on and slidable along two rods 50, Fig. 1, each rod being connected by a pin 55, Fig. 4, to a torque arm 51, Figs. 1 and 4, the torque arms being connected in turn to an axle flange 54, Figs. 1 and 2, projecting from a fixed axle 49. The right hand end of the caliper, in Fig. 2, (which is the left-hand end in Fig. 4, Fig. 4 being an elevation of the far side of Fig. 2), has secured in it, by means not shown, a brake pad 47 for engagement with face 45a of disc 45, the disc being secured at 44 to a rotary shaft 41 to which a vehicle wheel 40 is also secured at 42, Fig. 2 In operation when two pads 72, Fig. 2, are applied by two hydraulic actuators 71, Fig. 1, caliper 46 is moved by reaction in direction 48 to the "apply" position shown in Fig. 4. Such movement is opposed by a retractor comprising a Belleville washer 58 located between two washers 61, 62, of which washer 62 is retained by a drag ring 60 which tightly grips the rod 50. On brake release, Belleville washer 58 returns caliper 46 to its former position. Slack-adjusting.-As pad 47 wears, caliper 46 is impelled further to the right, in Fig. 4, on brake application, until the frictional resistance between drag ring 60 and rod 50 is overcome, whereupon ring 60 is forceibly shifted to a new position. A protective part 66 is secured, around the end of rod 50, to caliper 46 at 67, and contacts ring 60 in the "release" position.  Fig. 5 (not shown), depicts wholly diagrammatically, a complete brake in cross-section with a single cylinder cavity containing a single piston, to which a pad corresponding to pads 72 is secured. The piston rod protrudes through the cavity (provided wholly in the caliper) to the exterior; a retractor spring is located about the protruding part of the piston rod and acts between the face of the caliper and a washer secured to the rod. This spring has to allow for the sum of two retraction distances one appropriate to the caliper, the other appropriate to the piston.

Abstract: 1,198,996. Severing by grinding. LLOYDS (BURTON) Ltd. 5 Dec., 1967 [22 Dec., 1966], No. 57354/66. Heading B3D. A machine for severing lengths from tubes or rods comprises means for rotating a workpiece on a support 11, a power-driven abrasive wheel on an arbor 28, pressure applying means for displacing the wheel in a feed direction and means 34 for reciprocating the wheel in a direction transverse to the feed direction so that the wheel will engage the workpiece intermittently. The wheel and its driving motor 30 are mounted on an arm 29 which is counterbalanced and suspended from a structure 33 by links 32. A pneumatic cylinder 36 provides the power to swing the arm about the lower pivots of the links and feed the wheel down into the rotating workpiece while an hydraulic cylinder 34 acting between the structure and the links provides the required reciprocating movement perpendicular to the direction of feed. The workpiece is fed into the machine on raised rollers 12 and then lowered by pneumatic cylinders 13 on to roller supports 11. During a severing operation the workpiece is rotated by rubber friction rollers (15), Figs. 1 and 3 (not shown), which can be pivoted into engagement and withdrawn by pneumatic cylinders (19, 20), the friction rollers being slightly inclined to bring the workpiece to bear on an end stop.

Title: Magnetic recording systems
IPC: G11B27/30
Filed: 1970-12-22
Abstract: 1319358 Digital data recording INTERNATIONAL BUSINESS MACHINES CORP 22 Dec 1970 [29 Dec 1969] 60730/70 Heading G4C Digital data is recorded on multiple track magnetic tape with resynchronization signals interleaved among the data and this is used to resynchronize the recording system of the tape, e.g. in case of separation of the tape from the recording system or a crease in the tape. This can be effected using PE (phase encoding), FM (double frequency recording) MZE, MFE (modified phase encoding) or NRZI coding. Each track is divided into a plurality of discrete intervals and a recorded signal polarity change after a predetermined count of discrete intervals represents either binary 1 or binary 0. A synchronization pattern of signal polarity changes; which do not represent binary digits in that recording system, are recorded on each track, and means including a counter determine whether read out signal polarity changes represent binary 1's or 0's. Resync means recognize the pattern and produce an output signal which is used to synchronize the counter with the medium.  Apparatus.-A magnetic tape 10 has four tracks with bytes of data recorded in parallel (possibly staggered), and a conventional reading circuit 11, including deskewing apparatus 14, and passes signals from each track to a resync control (e.g. control 16 for track 0) including a self clocking digital detector 21 which produces read back signals (the differential of the MZE recording signal) on line 22 and clock (VFG) signals on line 23. The VFC signals are used for synchronizing the operation of detector circuits in circuit 11 where a counter 12 counts the deskewed bytes and thus predicts the occurrence of a resync. signal. Signals on lines 22, 23 pass to wavelength gate 25 and thence to a pattern detector 26 to detect the resync pattern. The gate 25 supplies signals on lines 27, 28 depending on the polarity of the data signal and thus detector 26 determines the pattern of signal changes using counters 43, 44. Fig. 1 uses MZE recording where data is represented by signals of four different durations. A resync pattern consists of two successive 5 unit signals which are bounded by binary 1's (Fig. 2). A simplified pattern detector (Fig. 4, not shown) may be used with PE or FM coding and another one (Fig. 6, not shown) may be used with NRZ1 coding. The circuit 11 also includes error detecting and correcting circuits (not shown) for dealing with tracks where readout fails.

Patent GB-724294-A (GB)
Abstract: 724,294. Photo-electric control systems. SANGAMO WESTON, Ltd. March 3, 1953 [March 4, 1952], No. 5901/53. Class 40 (3). In a photo-electric device for effecting a control in response to the intensity of radiation incident on the cell, the current output of the cell is used to vary the radiation incident on the cell so as to limit it to a predetermined maximum. The invention is described with reference to switching on street lamps as daylight fades. As shown, the photo-cell 10 controls a sensitive relay 11 to close moving contacts 12 with one of a pair of fixed contacts 13, 14 according as illumination rises or falls. If illumination rises, contacts 12, 13 close, energizing the field winding 24 of a motor 21 which runs to rotate a graded circular filter 15 which may be a disc of solenized material positioned over the cell to reduce the illumination of the cell, until contacts 12, 13 part. As illumination rises again filter 15 is again rotated until a finger 17 carried by the cam opens contacts 30 in series with motor field 24. Thus the illumination of the cell is maintained substantially constant over the range of the filter. As illumination falls contacts 12, 14 close, motor field 23 is energized and the filter is rotated to increase the intensity of light on the cell. This continues until a cam 18 carried by the filter closes contacts 33 switching on a load such as a street lamp. A limit switch 29 actuated by finger 17 is provided to limit the rotation of the filter when the least opaque part of the filter is positioned over the cell. To avoid switching of light due to momentary changes in illumination such as cloud effects thermal delay switches may have their heater windings brought into circuit by the sensitive relay (Fig. 31, not shown). In the arrangement of Fig. 4 instead of a rotating filter being provided over the cell, the cell itself is so pivoted as to alter the amount of illumination it receives. As shown, the cell 70 is mounted by an edge on a rotatable bar 71 which also acts as an axle for a disc carrying switch actuating projections (Figs. 5 and 6, not shown). The cell is mounted in a box 72 provided with an aperture 73, the inside of the box as far as line X being painted white while the remainder is non- reflecting.
