Title: Improvements in or relating to gramophone record changers
IPC: G11B3/095
Filed: 1957-08-12
Abstract: 862,683. Automatic gramophones. ELECTROACUSTIC G.m.b.H. Aug. 12, 1957 [Aug. 10, 1956], No. 25413/57. Class 40 (2). In a record changer for playing different sized records, in which the pick-up arm is oscillated by the cycling cam-disc to form a record diameter sensing means and causes a cam follower arm and the pick-up arm to be relatively displaced in accordance with the detected diameter, repeating means are provided to selectively stop the record change mechanism and a raised control wall on the cam-disc is movable to a position to render the restoration of the initial relative position of said follower and pick-up arm inoperative. The movement of the pick-up in both planes and the record release is controlled by a cycling cam-disc 8. The horizontal movement of the pick-up is controlled by an upper cam track which engages a follower 13 on an arm 14 frictionally coupled to the pick-up arm axis. The follower normally follows oscillatory parts 40, 41, 42 of the cam track during a recordchanging operation while a feeler element 25 and associated roller 26 on the pick-up is held against the lowermost record of the stack. When the element 25 engages the edge of the lowermost record, the frictionally coupled arm becomes set relatively with regard to the pickup arm (and an arm 15 rigidly attached thereto) in accordance with the record diameter detected, and the stylus is subsequently set down at an appropriate radius. The initial displacement between arms 14 and 15 is normally restored after playing of a record by a raised cam surface 29, which, however, can be swung to an inoperative position about a pin 30, when it is desired to carry out a REPEAT operation, by the operation of a control 35 which moves a cam 34 into the path of a lever 33 rigidly secured to pin 30 and cam 29. At the same time members 24 and 20 are moved into positions indicated in Fig. 1 to prevent a record being released to the turntable and the pick-up being raised to engage the lowermost record of the stack, respectively.

Title: Method and a substrate body for the cultivation of plants
IPC: A01G31/00
Filed: 1974-06-10
Abstract: 1473172 Cultivating plants O RUTHNER 10 June 1974 [6 Nov 1973] 25696/74 Heading AIM The roots of plants cultivated in greenhouses, are encouraged to grow downwardly by a method of cultivation in which seeds are cultivated in synthetic substrates 5, surrounded by a sleeve 10 preventing lateral emergence of the roots, until they reach a certain size when a second piece of substrate 8 is added. The sleeve 10 is then slid down over the combination of substrate bodies to the level at which root emergence is desired for further cultivation within the green house. When the plants are hardy enough to survive their intended environment outside the greenhouse they may be planted in holes lined with nutrient substances, these holes may be irrigated and ventilated by various means. Initial cultivation may take place in green house installation comprising one or more conditioned chambers in which the life cycle of the plant may be accelerated to reduce the time taken to reach a state of growth resistant to conditions in the intended environment.

Title: Improvements in the production of metal powder and metal granules
IPC: B22F9/08
Filed: 1965-06-17
Abstract: <PICT:1107115/C6-C7/1> A method of disintegrating metal comprises discharging a stream of condensible vapour under conditions which cause it to mix with a cooling agent so as to induce rapid condensation attended by vigorous agitation and shock phenomena in a limited zone of the stream, discharging a jet of molten metal to contact the zone whereby the molten metal is shattered into particles and collecting the particles in a quenching liquid. Fe, Ni, Co, Cr, Cu and their alloys are powdered in a disintegration tank 14 by impinging saturated steam jets 12, 13 on to a ribbon shaped jet of liquid metal and condensing the steam with air, N2 or water curtains from nozzle 15.  Particles are collected in a quenching bath of water at 60 DEG C. at the bottom of the tank, the particles solidifying before reaching the bottom of the bath.  Suitable conditions for disintegration are indicated by vibrations in a feeler placed in the steam jet.  The jets can impinge at different angles and heights and spray or shower nozzles may be used. N2 may be supplied to the tank to prevent oxidation.

Filed: 1944-12-22
Abstract: 576,616. Ironing-presses. WHITAKER, Ltd., R. G., and GRAY, F. T. Dec. 22, 1944, No. 25723. [Class 138 (ii)] [Also in Group XXXII] A linearly moving machine part, e.g., the pivoted beam of a garment press is provided with means for checking its motion at the end of its stroke. The member 2 is secured by the lug 24 tc the pivoted beam and slides in a frame 1 secured by the bolt 9 to a stationary part of the machine An inclined pressure pad 14 has a web slidable in guides 12 at right angles to the member 2, and a spring-pack 17 urges the pad towards the member 2 which, when the invention is applied to a garment press carries one friction surface 22 only, as it is necessary only to check the upward swing of the beam. The engagement of the surfaces 14, 22 forces the pad back against the spring 17 which is flexed accordingly, and the angle of the surfaces is calculated in relation to the coefficient of friction, so that unwanted movements of the beam, due to the pressure of the spring or the incline, are prevented. The theoretical angle of the friction surfaces to the direction of movement is such that the tangent is substantially equal to the coefficient. The spring 17 may be replaced by, or supplemented by, a yielding mounting for the friction surfaces 22.

Title: Improvements relating to braking arrangements for railway wagons
Inventor: WATSON HARRY KENNETH
IPC: B61H11/02
Filed: 1956-08-28
Abstract: 874,227. Railway vehicle braking arrangements. HUDSON Ltd., ROBERT. Nov. 27, 1957 [Aug. 28, 1956], No. 26332/56. Class 103 (1). In a railway wagon having an emergency braking unit comprising a tie (3) secured to the wagon and securable to the next succeeding wagon when the wagons are coupled together, a pivotally mounted lever (5) is attached to the tie and an operating bar (10) is pivotally connected to the other end of the lever (5) and a braking device (17) supportable in an inoperative position by the operating bar while the coupling remains intact, the lever and bar being capable of movement such that the braking device can assume an operative position if the tie is subjected to a predetermined force after disconnection of the coupling. A flexible tie means 3, normally in a slack inoperative position when succeeding wagons are coupled together by coupling means 6, is secured at one end to a cable anchor 1 on one wagon and the other end is secured to a lever 5 pivoted at 7 on a second wagon; the lever 5 being held in the position illustrated by a shear pin 9 and sprag means 17 being held in an inoperative position by the U-shaped end 10a of bar 10 pivoted at 11 to lever 5. Failure or disconnection of coupling 6 between wagons 2 and 2a will result in a tightening of the tie means 3 which will shear pin 9 and more lever 5 in an anticlockwise direction to move U-shaped end 10a of the bar to allow the sprag means 17 to fall to the position illustrated in broken lines in Fig. 1. A further arrangement is disclosed in Fig. 3 where the bar 10 is provided with an extension 19 pivotally connected to the lower end of pivotally mounted lever 21 at end of wagon 2a. The upper end of lever 21 is pivoted with a flexible tie means 25 of the next succeeding wagon (not shown). By this means, failure of coupling 6 imparts a longitudinal movement to bar 10 as described above and movement of extension 19 also imparts anticlockwise movement to lever 21 to tension the flexible tie 25 and effect braking of the next succeeding wagon in the manner similar to that disclosed above. According to the Provisional Specification any suitable braking means can be used for example a wedge to act in a selfenergizing manner between a reaction plate and the rim of a wheel, or alternatively skid plates could be used.

IPC: F42C15/196
Filed: 1968-06-04
Abstract: 1,215,519. Projectile fuzes. BREVETS AERO-MECANIQUES S.A. 4 June, 1968 [9 June, 1967], No. 26431/68. Heading F3A. A percussion fuze for a spinning projectile comprises a striker 2, a relay charge 12 mounted in a centrifugal rotor 11 which is movable about an axis perpendicular to the axis of the fuze to align the charge 12 with the striker and an explosive device 9, a centrifugal locking device 14 for the striker, and a retractable blocking member 17 which maintains the rotor in its safety position, the blocking member being permitted to retract from its active position, in which it is retained by the centrifugal locking device 14, only when the centrifugal locking device is no longer operative. The blocking member 17 is in the form of a capsule or a pin (17, Fig. 5, not shown) and is retractable automatically under the action of centrifugal force or axial acceleration, or is retracted by springs or ramps responsive to centrifugal force or axial acceleration, or by the pushing action of the rotor as it rotates. The centrifugal locking device 14 is in the form of a split annular bolt surrounded by a split ring 16 and a spiral element 15 which progressively unwinds under the action of centrigufal force. Upon firing a projectile fitted with the fuze, the striker is moved forwards by balls 4 which climb along a surface 5 under the action of centrifugal force, whilst the centrifugal locking elements and blocking device operate to free the rotor. If the rate of spin of the projectile drops sufficiently before impact of the projectile with a target, the force of a spring 6 overcomes the centrifugal force acting on the balls 4 and causes self-destruction of the projectile.
