Title: Improvements in apparatus for lifting and tapping barrels
IPC: B65G65/24
Filed: 1924-08-26
Abstract: 230,716. Adolfsson, A. E. Aug. 26, .1924. Barrel tilters.-A barrel tilter comprises a base ,a and stand b supporting adjustable bearings e to which are attached pulleys d over which pass loops i of cord within which the barrel is carried. The barrel is tilted as required by rotation of a crank handle f. The barrel is moved into the slings first by moving it up the slope k and then, by means of a handle h, rotating the bearings e about their pivots g so as to lower the pulleys and the loops, so that the barrel can be taken into the slings. The barrel is then raised by means of the handle h. The bearings may be connected by a tube to which a one-arm lever may be attached for rotating the bearings.

Title: Improvements in or relating to card reading mechanisms
IPC: G07C9/00

Abstract: 1,025,075. Attendance checking; sensing record cards. CONTROL DATA CORPORATION. May 22, 1963 [May 22, 1962], No. 20400/63. Headings G4M and G4T. A mechanism for sensing a perforated card, e.g. a workman's identity card, includes a plurality of sensing fingers 68, Fig. 13, which are pivoted into engagement with the card 48 the fingers 68 being displaced as the card moves into a sensing chamber by engagement of the sensing tips of fingers 68 with the perforations 100 in the card. Each finger 68 carries a bifurcated brush 94 which connects a printed circuit conductor 222 with one of contacts 218 in dependence on the position of perforation 100 in the card. When card 48 is inserted its edge engages tabs 96, Fig. 3, on control fingers 66 which are thereupon depressed, and in turn cause the sensing fingers 68 to be unlatched so that they pivot about studs 88 and bring their tips 98 into engagement with the card. Each finger 68 is prevented from moving down with the card by a bail 112, Fig. 6, engaging a shoulder 110 on the fingers 68, but when a tip 98 drops into a perforation the finger moves clear of bail 112 and is carried down by the card. When the card has been fully inserted, rollers 148 drop into notches 154 in control fingers 66, shaft 144 is rotated and brings pawls 156 into engagement with the serrations 158 on the sensing fingers 68 to lock them in the operated position. Other devices may be provided to lock the card in position and for preventing incorrect manipulation of the card. The information sensed from the card is transmitted to a central processor by means of a rotary switch which energizes conductors 222 in turn, a circuit path being established by brushes 94 between each conductor 222 and one of conductors 606 leading to the central processor. Further information may be transmitted from one or more manually adjustable multi-position switches. The apparatus is restored to normal at the end of the scanning operation by means of reset solenoids.

As shown the rotor 15 is divided into upper and lower chambers by a separator 59, and the components are projected in separate streams 61, 62. As shown the apertures 60 are narrow vertical slots (see also Fig. 2, not shown), but they may be perforations; the rotor may have a single chamber; and there may be attached to the rotor shaft 34 in the chamber a disc (79), an array of radial rods (121-124), or a swash plate (130) (see Figs. 3, 5 and 6, not shown) to intercept the liquid before it reaches the bottom of the chamber. The sand is supplied through an annular passage 26 controlled by an annular gate 29 and actuator 30, and is formed by guides 25, 45 into a downwardly conveying hollow curtain. There is a spray shield 54. In another embodiment (Fig. 4, not shown) the gate 29 has an adjustable stop (102); and there is a further internal guide (45B) which causes the solid to fall substantially vertically on to a funnel surface (54B) which may be vibrated and direct the mixture into a mould. There are axial air jets which cause the sand to fall in the region of the rotor during opening and closing of the gate 29. The components may be mixed in the rotor or commingle in the space between the rotor and the sand curtain. The shield and guide surfaces may have disposable liners.

Abstract: 762,709. Kinematograph cameras. PHILIPS ELECTRICAL INDUSTRIES, Ltd. July 20, 1954 [July 20, 1953], No. 21200/54. Class 97(1) A driving means for a kinematographic camera, for successive reproduction of X-ray images, comprises an intermittently rotating shaft which can be coupled to the normal film drive of the camera by means of an electromagnetically operated coupling controlled by a continuously moving switch mechanism. As shown, a continuously driven shaft 4 is connected to shaft 3 by a Maltese Cross mechanism 5 so that shaft 3 makes one complete revolution during part of one rotation of shaft 4 and is at rest during the remaining part of such rotation, during which time an exposure may be made. The shaft 3 may be connected to the main film drive 2 of the kinematograph camera 1 by an electromagnetic coupling 16, which is energized by a coil 15 controlled by a continuously rotating switch. The latter comprises an arm 6 rotated over contacts 11 by the main drive 4 at such a speed that it travels between adjacent contacts 11 for each revolution of shaft 3. Each contact 11 may be connected by a removable plug 13 to a corresponding contact 12. If all the plugs are inserted the coupling 16 will be energized for each rotation of shaft 3, but by removing any of the plugs 13, the coupling 16 can be rendered inoperative for any desired number of revolutions of shaft 3.
