Abstract: 751,222. Rounding and backing machines. FRENCH, L. J. B. R. Jan. 4, 1955 [Jan. 4, 1954], No. 159/54. Class 16 A method of rounding and backing books consists in displacing the book sections on one side of the centre line in the direction of the fore-edge from the spine and subjecting the displaced section on the back to a differential pressure from the centre of the book outwardly and then adopting the same procedure to the remaining sections on the opposite side of the centre line. In the machine shown, jaws 1, 2 on opposite sides of the book, 3 are maintained in gripping engagement by backing plates 4 mounted in a supporting frame 5 and pressure is adjusted by clamping screws 6. Coiled springs 7 press the jaws 1 and 2 up to the position shown in Fig. 1 and a rounded stop 8 is mounted beneath the book and is adjustable vertically, in a slot 9 where it is locked by a nut 10, to a position where it touches the foredge of the book 3 while a roller 15 rests on the spine. The roller 15 is mounted on an axis 16 carried by an operating handle 13 pivoting about an axis 14 and the handle 13 also carries a cam 12 to engage a roller 11 on each jaw 1, 2, to move each jaw downwardly against the springs 7. Each backing plate 4 has an opening 17 in which is mounted a pawl 18 pivoted at 19 and urged into engagement with ratchet teeth 20 on the adjacent jaw by a coiled spring 21. As shown in Fig. 3, the handle 13 is first moved from its central position to one side, when the jaw 2 will be pressed down by the cam 12 engaging roller 11 so that the book sections on that side of the centre line are displaced downwardly until the fore-edges contact the stop 8 -and at the same time the roller 15 will be moved over the spine to spread the sections on that side to round and joint the back. The pawl 18 will engage one of the ratchet teeth 20 to hold the jaw 2 while the operation is repeated by moving the handle 13 over to the opposite side. The roller 15 and jaws 1, 2 will be at least equal to a book's length and generally two cams 12 will be interconnected and engage two rollers 11 on each jaw.

Title: Improvements in or relating to variable speed gearing
IPC: F16H3/66
Filed: 1923-01-03
Abstract: 212,679. Brown, W. S. F., and Maina, J. Jan. 3, 1923. Variable-speed epicyclic gearing comprises three sun gears d, e, f, Fig. 1, secured to a driving-shait b and meshing with separate sets of planet gears g, p, t respectively. The carrier r of the planets p is loose and has two internal gears o, w fixed to it meshing with the planets g, t, respectively, and an external gear ring 3. An internal gear s meshing with the planets p turns loosely on the carrier v as a bearing and has external teeth 2. This carrier v is in two parts bolted together. The carrier l of the planets g is secured to a driven shaft m. The carrier v of the planets t is loose, having external gear teeth 4 and a friction clutch surface 6. The high speed is a solid drive obtained by sliding a clutch cone 7 upon the shaft b into engagement with the clutch 6. A middle speed is obtained by arresting the ring 4, when the carrier v turns forwards, assisting the train d, g, o. The low speed is obtained by arresting the carrier v through its gear ring 3, the train d, g, o then working alone. Reversed driving is obtained by arresting the ring 4, when the carrier v turns rearwardly carrying with it the planets g sufficiently. The arresting of the elements 2, 3, 4 is effected by a pinion 12, Fig. 2, which is slid on a shaft 10 into mesh, and then arrested by a spring-pressed brake 15. The pinion 12 is shifted by selective mechanism shown in Figs. 4 and 1. A striker 19 is journaled loosely between collars on a bar 18, which is slid axially by a hand-lever 30. A fixed stud 32 projecting into a cross-slotted groove 31 in the bar 18 guides the mechanism. Locking bolts 42 are provided. The bar 18 slides into the splined boss 20 of a cam 22 operating the clutch 7 through a cranked lever 23. The lever 23 is mounted with a lost-motion connection 27 on a shaft 24, which carries a fixed fork 26, Fig. 3, for controlling the brake 15. As applied to a vehicle, the shaft 24 is operated by the clutch pedal. The invention includes arrangements with additional trains for more speeds.

Title: Improvements in and relating to speed control means for d.c. motors
IPC: H02P7/06
Filed: 1945-01-03
Abstract: 591,310. Automatic control systems PEARSON, S. O. Jan. 3, 1945, No. 302. [Class 38 (iv)] In an automatic speed regulator for shunt or compound wound or separately excited D.C. motors, a. small magneto-generator is coupled to the motor shaft and supplies the coil of a vibrating contact relay, either directly or through a-thermionic amplifier, to control the relative lengths of the open and closed periods of an associated set of contacts, which, operating through an exciter dynamo determine the strength of the motor field or, in one embodiment, the armature current and hence its speed. In Fig. 1, the magneto-generator 36 is driven by motor 35, the speed of which is to be controlled, and the output of 36 is applied to coil 37 of a vibrating contact relay. The contacts 39 of the relay control the periodic insertion of the resistor 44 in the field circuit of the negative booster 41 which is in series with the shunt field 42 of the motor 35. A fall in speed of the motor 35 produces a fall in the current flowing in 37 which increases the ratio of closed to the open periods of the contacts 39 and hence raises the generated E.M.F. of the negative-booster 41, which, being in opposition to the bus-bar voltage reduces the excitation of 35 and raises its speed. For an increase of the speed of the motor above the datum, the regulator functions in a similar sequence to increase the excitation of field 42, the datum being set by variable rheostat 38. In Fig. 2 (not shown), the sensitivity of the vibrator relay is increased by supplying the coil 37 from the magneto-generator through a thermionic amplifying device. In Fig. 3 (not shown), the system is adapted for use with a Ward-Leonard drive. The separately excited controlled motor 46 is supplied by generator 49, the held 50 of which is energized by exciter 52. The field 53 of the latter is connected across the armature 49 in series with resistor 56 across which are connected the contacts 55 of vibrating relay 55-54. The coil 54 of the relay is supplied through a thermionic amplifier by the magneto-generator 48 driven by the motor. Changes of motor speed are reflected in corresponding changes in the output of the magneto which are amplified and then applied to the vibrating contact relay which makes the appropriate alteration in the excitation of 52 to produce a connecting charge in the output current of 49. Specifications 591,309 and 591,311 are referred to.

Abstract: 1,133,709. Semi-conductor devices. EGYESULT IZZOLAMPA ES VILLAMOSSAGI RESZVENYTARSASAG. 4 Jan., 1966 [5 Jan., 1965], No. 368/66. Heading H1K. In the manufacture of a diffused junction oxide-passivated semi-conductor device silicon is deposited from the vapour phase on an oxidized surface of a silicon wafer and is then converted to the oxide. The deposition and oxidation processes may be repeated if desired. In a typical method the surface of a 1-10 # cm. N type silicon plate is oxidized by heating in moist oxygen and windows formed in it by conventional photoresist and etching techniques. Boron is diffused from a gaseous mixture of boric oxide and argon through the windows to form P type base zones. After a further period of surface oxidation pure or doped silicon is deposited over the masked face from a gaseous compound of silicon, and oxidized. Windows are etched through the oxide layer within the original windows and phosphorus diffused in to form the emitter zones. Aluminium contacts are then provided by vapour deposition and the plate split up into individual transistors. These are mounted on headers with gold lead wires bonded to the contacts.
