Title: Digital magnetic recording system
IPC: G11B5/09
Filed: 1973-01-15
Abstract: 1406915 Magnetic recording system INTERNATIONAL BUSINESS MACHINES CORP 15 Jan 1973 [18 Feb 1972] 1954/73 Heading G4C A magnetic recording system records data representing signals of a given bit periodicity together with a sine wave clock and bias signal at an even integral multiple of the data periodicity and with a fixed phase relationship to the data signals. A typical frequency response curve for a magnetic record/replay system is shown. A sine wave clock and bias signal 13 having a frequency twice that of the data signals and a larger amplitude is fed, together with the data signals, to a linear adder whose output is recorded, e.g. on a tape. One or more other control signals 15, 16 may also be used and the clock and control signals are separated on read out, e.g. by frequency tracking filters, and used separately or in various combinations to control read out. Deskewing.-Clock signal 13 and a further control signal 15 have a beat frequency which defines a series of data frames. Correction of skew within such frames may be as described in Specification 1,287,220. Write retry on error.-Control signal 16 is supplied to the linear adder associated with each track on a tape so long as the recorded data is error free. A monitor responds to erroneous recording to inhibit signal 16 for the appropriate frame. Where only a single track is in error and the data is associated with a correction code capable of dealing with such an error no rewriting is necessary. Where more than one track is in error the erroneous frame is rewritten. The data may be read in forward or reverse directions, and the absence of signal 16 may be used to provide error pointers, see Specification 1,274,630.

Abstract: 1,169,105. Making magnetic heads. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 16 Jan., 1967 [18 Jan., 1966], N. 2253/67. Heading B3A. [Also in Division G5] A mono- or multi-track magnetic head comprising a magnetizable core containing a useful gap, one or more reading windings and an auxiliary winding 4 in which a varying current is passed during operation, is made by providing a row of lead-in holes 11 and auxiliary holes 13 in a magnetic material block by ultrasonic drilling and cutting the block along planes which contain the auxiliary holes so that each boundary surface 17, 18 of the core includes part of the wall of an auxiliary hole. In one embodiment, Fig. 4 (not shown), the auxiliary winding is wound using one lead-in hole. The holes 11, 13 need not extend completely through the core but may be drilled from side 26 and material is then removed from the opposite side of the core so that a U-shape profile is formed and the holes extend through the bridge. The core is then cut along planes 21 up to point 22 and the central cut filled with non-magnetizable material e.g. glass the core is then cut from the face 26 along planes 24 to the point 22 and the central cut filled with non-magnetizable material so that the parts 27, 28 are magnetically separated. A polepiece which contains the useful gap, Fig. 7 (not shown), is then secured to the core to complete the magnetic head. In an alternative embodiment, Fig. 6 (not shown), a block of magnetic material (31) is cemented to a ceramic jig (29) after the drilling and the upper surface ground flat or into a U-shape. The block is then sawn along planes (33) to form separate parts (36) and the gaps filled with a non- magnetizable adhesive, e.g. glass. A suitable polepiece can then be secured to the multi-track core to form the multi-trackhead.

Title: Improvements in or relating to railway vehicle bodies
IPC: B61D31/00
Filed: 1948-01-27
Abstract: 637,891. Railway sleeping cars. BUDD CO. Jan. 27, 1948, No. 2404. Convention date, July 23, 1947. [Class 103 (iv)] A railway sleeping car has a room defined by spaced parallel vertical walls, a fixed length upper berth extending lengthwise between said walls, the berth being movable upwardly and laterally from a low level horizontal in-use position to a high level stowed position adjacent the room ceiling, means for guiding and supporting said berth in its movements comprising trackways on the spaced parallel walls and rollers associated with the opposite ends of the berth and continuously engaged with said trackways, and means for locking said berth in its in-use and stowed positions. Referring to the drawings which are interior views of the opposite end walls of the room, the berth 23 is made up within a shallow box-shaped member 24 provided with rollers 27 which engage in trackways 25 mounted adjacent the car roof and the outer wall 11 on the spaced end walls 15, 16, and are closed at their lower extremities to provide a support for the rollers. The member 24 is pivoted at 34 to a U-shaped frame 32 comprising arms 33 and a tubular connecting member 35, the upper extremity of each arm carrying a roller 27 to engage in the respective trackway 25. In the stowed position adjacent the roof of 'the vehicle, Fig. 1, the member 24 is locked by a handle 52 to the frame 32 so that they are co-planer and to lower the berth to its in-use position it is swung outwards and downwards along the trackways until the rollers mounted on the member 24 rest on the lower closed end of the trackways with the berth in the position shown by chain-dotted lines in Fig. 2. The member 24 is then unlocked from the member 32 and pivoted about the lower ends of the trackways to the horizontal position in which one inboard corner is supported by a readily removable tie rod 39 and the other inboard corner is supported on a bracket mounted on one of the end walls. To reduce the effort needed to move the berth from one position to another a counterbalancing device is provided (Figs. 3, 4, not shown), which comprises two interconnected co-axial springs of different strengths secured at one end to a frame 31 and at the other end to the member 24. Movement of the berth along the horizontal portion of the trackway causes the weaker of the two springs to be compressed to its solid length and thereafter, during movement of the frame over the curved and vertical portions of the trackway, the stronger spring is compressed. During the return movement of the berth the springs assist its movement by operating in the reverse sequence. To ensure that the berth is not moved to the horizontal portion of the trackway before the member 24 and the frame 32 are locked together a catch 35 is provided in the roof which must be manually released before the berth can be moved beyond the chain-dotted position shown in Fig. 2.

Title: Sequence controller for valves controlling fluid flow
IPC: F16K11/16
Filed: 1961-01-24
Abstract: 923,012. Valves. F. SPRAGUE. Jan. 24, 1961, No. 2719/61. Class 135. A valve, e.g. controlling a pneumatic windscreen wiper incorporating a parking device, has a body 10, with two, as shown, or more parallel bores 12, 20, interconnected by a passage 30; a port 32 leading to the parking device opens laterally into the bore or bores 20, each of which has an axial port 26 connected to the wiper motor, whilst the bore 12 incorporates a pressure supply port 11. The inner parts of one or more of the bores has a vent port 36. Across the bore 12 is a seat 40 with a spider 46 guiding the stem 48 of a movable frusto-conical closure member 50; the stem 48 which is attached to a piston 52 has an inwardlyextending part 56 slidable in the tubular rod 58 of a disc 60 on the other side of which is a plunger 62. A spring 64 is disposed intermediate the piston 52 and disc 60. The bore 20 houses a spring-loaded piston closure 70 with a plunger 74. Both plungers 62, 74 protrade beyond the body into an annular cam groove 96 or 98 in a manually-operable cam disc 84 whereby the positions of the closure 50 and piston 70 are controlled. Upon rotating the cam disc 84 the closure 50 is slightly opened and the piston closure 70 covers the port 32 whereby the supply port 11 is connected to the motor port 26; continued rotation of the disc 84 then controls the position of the closure 50 only and hence the speed of the motor; the cam grooves may each incorporate an increased depression to enable the end of the groove to be " felt." Further movement of the cam disc restores the parts to the position shown so that the motor port 26 is connected to the parking port 32 whereby the parking device is operated. In a modification, the piston closure slidably houses the piston of the other closure, the two closures being concentric.
