Title: Reproducer for signal information recorded on tape
IPC: G11B23/04
Filed: 1955-07-26
Abstract: 780,546. Magnetic recording and reproducing apparatus. MASTLING, E., MASTLING, R., and SCHWARZ, [nee MASTLING], M., [trading as MASTLING, E., [Firm of]]. July 26, 1955 [July 31, 1954; Dec. 6, 1954], No. 21525/55. Class 40 (2). In a magnetic tape record apparatus a removable magazine contains two bodily movable spools, between which the tape passes, and is characterized in that it has a wall with an aperture exposing a length of the tape, and spring means urging the spools towards said wall to enable a drive roller and transducer installed in the main body of the apparatus to engage the tape. The removable magazine comprises two walls 8<SP>1</SP>, 8<SP>11</SP> provided with slots 13<SP>11</SP>, 14<SP>11</SP> to act as guides for the spool hubs 13<SP>1</SP>, 141 which are urged outwardly by wire springs 15, 16 so that the surface of the tape on the take-up spool 13 is engaged by the drive roller 11, and that on the supply spool 14 by the felt lining of the magazine which provides a slight frictional drag. A pressure pad 22 holds the tape against the transducer 3 which is resiliently mounted in a housing 31. The tape may be rewound by merely inverting the magazine in the apparatus, and the transducer may be offset from the centre line of the tape so that two tracks may therefore be recorded and reproduced. Figs. 6 and 7 (not shown) illustrate a magazine with arcuate guide slots and having a wire spring with a centre coil which enables it to pivot about a central pin whereby differential pressure is applied to the spools. Figs. 8 and 9 (also not shown) illustrate a magazine having no guide slots, but in which the position of the spools is controlled by crooked ends of the wire pressure springs.

Title: Improvements in or relating to master cylinders for hydraulic braking systems
Inventor: FANTHAM HAROLD
IPC: B60T11/16
Filed: 1952-08-28
Abstract: 716,008. Hydraulic brakes. GIRLING, Ltd. Aug. 26, 1953 [Aug. 28, 1952], No. 21619/52. Class 103(1) In a master cylinder for an hydraulic braking system, a port b in the forward end of the cylinder leading to a liquid reservoir is controlled by a valve head s mounted with a certain degree of axial freedom on the forward end of a telescopic sleeve l, j, of limited extension which projects forwardly from the piston d within the cylinder and is normally held extended by a spring v. When the piston d of the master cylinder a is advanced to apply hydraulic fluid to the brakes, via the radial port c, the pressure in the cylinder rises and the flanged valve head s moves forwardly so that the sealing member t seats against the end of the cylinder and cuts off communication between the cylinder and the reservoir through passage b. When the brake pedal is released, the piston is returned by the spring v and when the pressure in the cylinder falls below the static head in the reservoir, the valve head s will move rearwardly away from the end of the cylinder and establish communication again with the reservoir. If this does not occur before the piston d approaches its fully retracted position, against the circlip f, the pin p will engage the rear end of the slot q in the valve stem r and will positively move the valve into the open position.

Title: Improvements in variable speed power transmissions
IPC: F16H61/688
Filed: 1946-07-29
Abstract: 615,143. Change-speed gearing. FORD MOTOR CO., Ltd. July 29, 1946, No. 22484. Convention date, Aug. 22, 1945. [Class 80 (ii)] An automatically-operated change-speed gear for motor vehicles has input friction clutches in parallel, one driving through a one-way clutch a main transmission shaft having a directdrive clutch connection with the output shaft, and the other driving a countershaft having gears meshing gears mounted on, and having lockable overrunning clutch connections with, the transmission and output shafts respectively. As shown, hydraulically-operated speed and torque responsive main friction clutches B, A in parallel drive directly and through a one-way clutch 21 respectively, nested shafts 23, 22. A countershaft 42 carries gears 43, 44 meshing gears 24, 26 which are mounted on the shafts 23, 22 directly and through a one-way clutch 25 respectively, and carries also a gear 45 manually slidable to mesh, directly for forward drive or through a reversing idler pair 48 respectively, a gear 39 connected to the output shaft 35 by a one-way clutch 40. Both the clutches 25, 40 may be bi-directionally locked by speed and torque responsive positive clutch members 27, 33 slidably splined on the shafts 22, 35 respectively and engaging the gears 26, 39, the member 33 being also movable through a neutral position to engage clutch teeth 32 on the shaft 22 for direct drive. First speed or reverse, alternatively, are obtained, after moving the gear 45 to the appropriate position, by engagement of the clutch A, which occurs automatically upon initial enginethrottle opening, the drive then passing through the gear pair 26, 44 to the countershaft. During reverse drive the positive clutch 33, 39 is engaged since the one-way clutch 40 cannot transmit reverse torque. The additional engagement of the clutch B, which occurs under suitable speed and torque conditions, gives second speed through the gear pair 24, 43, the clutch A remaining engaged and the gear 26 overrunning the shaft 22. The transmission in first and second gears is normally through the free-wheel clutch 40, but thus may be bi-directionally locked by the clutch 33, 39 through overriding manual means which in second speed thus provides engine braking. For direct drive, the clutch A is momentarily disengaged to allow the engagement of the clutch 33, 32 and is then re-engaged. A positive overdrive is brought in, after disengaging the clutch B to allow the engagement of the clutch 27, 26, by re-engagement of the clutch B when the drive passes through the gears 24, 43, 44, 26 to the shaft 22, the clutch 21 overrunning. On subsequent changing-down, direct drive is re-established by disengaging the clutch B ; second speed by disengaging the clutch 27, 26, re-engaging the clutch B and disengaging the clutch A ; and first speed by disengaging the clutch 33, 32, engaging the clutch A and disengaging the clutch B.

Abstract: 895,420. Lining the surfaces of vessels. FARBWERKE HOECHST A.G. July 14, 1958 [July 12, 1957], No. 22536/58. Class 93 [Also in Group XXIX] The surface of a vessel, e.g. the wall of a concrete, brickwork, iron, or wood tank, is lined by bonding to the surface by means of a hardenable unsaturated polyester resin, furane resin or phenol-furane resin a cloth, which may be wide-meshed and may be of asbestos or glass fibre or of natural, regenerated or synthetic fibrous material such as cotton, viscose rayon, polyacrylonitrile, or polyethylene glycol terephthalate, and then applying a coating of the hardenable synthetic resin to the bonded cloth. The unsaturated polyester resin is formed from ethylenically unsaturated dicarboxylic acids, possibly including saturated dicarboxylic acids, and glycols, possibly including monohydric or trihydric alcohols, and possibly in the presence of polymerizable monomers such as styrene. The furane resin may be a furfuryl alcohol resin, a furfural-formaldehyde resin, or a furfuryl alcoholfurfural resin, and the phenol-furane resin may be a condensation product of phenol with furfuryl alcohol or furfural. In an example, a roughlyplastered concrete trough is coated with an unsaturated polyester resin containing a peroxide as hardener, an asbestos cloth is bonded to the coating by the same resin in such manner that the cloth projects over the wall of the trough, and a further coating of the same resin is applied and smoothed. Tanks may be built of tiles each provided with the protective coating. Specifications 845,529 and 876,087 are referred to.

[Also in Groups XXVIII and XL (b)] Process for making circular wave - guides comprises the steps of winding a helix of fine wire on to a mandrel formed of successive interlocking segments, while applying an adhesive material to bind the adjacent turns of the helix in peripheral contact, progressively removing segments of the mandrel from the forward end and replacing them at the receiving end. Wire from reels on radial arms 3 on a rotatable winding head 4 passes over ball races 6 on the head 4 and is laid on a mandrel 2 which slides axially on ball-races 12 on a fixed core 1. A plurality of wires may be laid in one or two layers and adhesive is applied to secure the turns together. Additional winding heads feed cotton and steel armouring tapes 9 to the waveguide. The mandrel 2 is formed of interlocking segments 13 and, as winding progresses, the last segment 16 is removed from the mandrel by a tool inserted through the hollow core, drawn back therethrough and reassembled at the beginning of the mandrel. On leaving the mandrel the waveguide is supported on a roller 11. The waveguide from the waveguide forming unit 29, Fig. 8, is laid in a trench 23. The unit 29 is mounted on a carriage 27 slidable on wheels 28 on a carriage 19 in turn movable on wheels 21 on rails 22 straddling the trench 23. As the waveguide is paid out from the forming unit 29 over rollers 31, 32 the carriage 27 is moved to the left until it trips a switch to move the carriage 19 quickly to the left and then stop. Alternatively the carriage 19 may be moved to the left at exactly the speed of production of the waveguide. Specifications 780,503 and 887,063 are referred to.
