Title: Flash welding apparatus
Inventor: CAVANAGH DANIEL A
IPC: B23K11/04
Filed: 1965-08-25
Abstract: 1,073,660. Welding by pressure. TAYLOR-WINFIELD CORPORATION. Aug. 25, 1965, No. 36442/65. Heading B3R. [Also in Divisions G1, G3 and G4] The relative movement between a pair of platens in a flash - welding apparatus is effected by an electrohydraulic arrangement responsive to a comparison between a signal corresponding to the desired platen spacing, which is varied in a predetermined manner with time during a portion of the flash-welding operation, and a signal corresponding to the actual spacing of the platens. As shown, Fig. 1B, a welding platen 12 is moved relative to a fixed platen 11 by an hydraulic actuator 16 controlled by a proportioning hydraulic servo-valve 64 responsive to the output of an electric servo - amplifier SA. The control signal to the servo amplifier is derived from the output of an operational amplifier A 4 . An upset valve 65, controlled by a solenoid 67, supplies a large volume of fluid to the actuator 16 at the end of the flashing time to bring the ends of the workpieces together and effect a weld. The movement is limited by an adjustable stop 27. The inputs to the operational amplifier A4, which has a parallel resistor R49, are provided through resistors R43-R48 which are equal in value to R49. The amplifier summates the positive inputs to resistors R43-R47, representing the instantaneous desired spacing of the platens, and a negative input to the resistor R48, representative of the actual spacing of the platens, which is derived from the slider of a potentiometer LP1 by the movable platen 14.

Title: Improvements in or relating to toys and games
IPC: A63F11/00
Filed: 1962-09-25
Abstract: 995,162. Board games; chance apparatus. M. GLASS, [trading as M. GLASS & ASSOCIATES]. Sept. 25, 1962 [Oct. 6, 1961], No. 36452/62. Heading A6H. A peg and board game wherein pegs are moved over an apertured playing board in accordance with the throw of a dice or instructions indicated by some alternative kind of chance apparatus, comprises means whereby visual and/or audio effects result from insertion of the pegs into certain of the apertures on the board, the operating mechanism of at least some of said effects including means for rendering such operation random. As particularly described, the game represents progress through a haunted house, the board 37 being of hollow construction and housing the operating mechanisms associated with the various effects. In most instances, the operating mechanisms are as shown in Fig. 2, each comprising a disc 57 lying beneath its associated hole 25 so as to lie in the path of a peg inserted therein, and mounted for free rotation and tilting movement about its supporting shaft 61. The disc, upon being engaged by a peg, thereby tilts and depresses the tail 51 of a surprise element 31 pivotally mounted within the board 37, thereby causing the element to project upwardly through a slot 55 in the playing surface of the board. Upon removal of the peg, the element 31 is retracted into the board either by gravity or by means of a suitable spring. The disc 57 may also be arranged to simultaneously or alternatively close contacts in an electric circuit to a lamp or bell, or to operate bellows actuating a whistle. In cases where the operation of the effect is desired to be random, the disc is either apertured or slotted so that for some positions of the disc the peg will pass through the disc without tilting the latter, or alternatively the periphery of the disc is slotted so that when a slot in the disc registers with the tail 51 of the corresponding element 31, tilting of the disc does not effect movement of the said element. The apparatus described also comprises a chance device 33 (Fig. 10) for controlling the movement of the pegs over the board, said device comprising a drum 125 inscribed with numbers on its periphery and mounted for rotation within a shell 124 on the board. A gear-wheel 137 secured at one end of the drum co-operates with a toothed sector on a lever 147 projecting from the shell to cause rotation of the drum, whilst a leaf-spring co-operating with a star wheel 134 secured at the other end of the drum ensures that when the latter comes to rest after rotation, a number is visible at the observation window 39. Movement of the lever 147 also operates bellows 153 controlling the whistle 157.

Abstract: 156,155. Press-und Stanzwerk Neviges Comm.-Ges. Lohe & Hacklõnder. Sept. 25, 1919, [Convention date]. Addition to 148,335. Padlocks; locks, revolving-barrel. -The pivot pin of the shackle of a padlock is carried by a disc rigidly coupled to the revolving cylinder of a pin-tumbler locking-mechanism. The pivot pin a may be fixed between a pair of such discs c, c, to which a corresponding pair of revolving cylinders e, e, with pintumblers, are rigidly connected by pins f, one in front of, and one in rear of, the pair of discs. In the form illustrated, the pin-tumblers are arranged in four rows, the key g having four corresponding bits. Insertion of the key positions the pintumblers to allow it to turn, revolving with it the discs c, c, and the cylinders e, e, and raising the shackle b to free its shorter leg, as shown in Fig. 2. On further turning, the shackle is thrown backwards as shown in Fig. 3 owing to its longer leg pressing against the edge of the slot in the casing. The opposite movement of the key brings back the shackle to its operative position and its removal causes the pin-tumblers to lock.it.

Title: Process for the manufacture of new soluble calcium salts and products obtained thereby
IPC: A61K33/06
Filed: 1932-12-28
Abstract: Double salts which posses therapeutic properties are formed by interaction of the calcium salts of polyoxymonocarboxylic acids derived from aldomonoses with the calcium salts of bionic acids derived from aldobioses.  The same double salts also result from the interaction of basic calcium salts of polyoxymonocarboxylic acids derived from aldomonoses with bionic acids derived from aldobioses. In each case the reaction takes place in presence of water and preferably at an elevated temperature and the double salt may, if desired, be isolated from the solution by evaporation to dryness at a low temperature or by addition of an organic solvent immiscible in water.  Examples are given of the preparation of double salts of calcium gluconate or mannonate with calcium lactobionate or maltobionate, and the use of calcium galactonate is mentioned. Specification 372,225 is referred to.
