Abstract: 400,730. Filling cans &c. JACKSON & CROCKATT, Ltd., J. G. and JACKSON, J. G., 64, Darnley Street, Glasgow. July 9, 1932, No. 19447. [Class 125 (ii).] In apparatus for filling paste, powder, &c. into cans, bottles, &c., of the type in which the paste is extruded through a delivery orifice D by a rotating helix C which is caused to recede from within the can &c. M as filling proceeds, by the resistance offered by the paste, the helix is arranged with its axis at a substantial inclination to the horizontal and extrudes material downwardly into a receptacle held in filling position by endwise support at its base. As shown, the base 2 of the hopper M is parallel with the helix axis and the endwise support for the can comprises a plate 20 which is raised by a manually-operated cam 25 acting on a lever 26 through the upper end of which the plate-supporting spindle 21 is screwed. The helix shaft 5 extends upwards through bearings 4 situated outside the hopper, and carries, on an adjustable collar, rollers 8. As shown, the helix is held in a retracted position, out of the can, by a trip gear K, against the action of a weight 9 connected to the shaft 5 by a cord 12. A gear E drives continually a clutch F which rotates a driving member 6 having jaws 7 with which, when the trip gear K is released and the shaft 5 pulled down by the weight 9, the rollers 8 engage. As the can fills the helix recedes from its interior and eventually the rollers leave the jaws 7, the helix ceases to rotate, and the upper end of the shaft is automatically engaged by the trip gear. The hopper may be provided with agitating blades 15, the bearings for which are situated outside the hopper, and an inspection window 29. The machine may be a multiple one, employing one trip gear common to, say, twelve helices, and the cans &c. may be fed to the hopper by two inclined belts and raised to the delivery orifices by a lever-operated board. A trough extending the length of the twelve delivery orifices may be disposed to catch drippings from the latter. Specification 221,600, [Class 94 (i), Packing &c.], is referred to.

Title: Improvements in halogenated aldehydes
IPC: C07C45/41
Filed: 1951-08-20
Abstract: A g -halogenobutyraldehyde of the general formula Hal CH2-CH2-CH2-CHO in which Hal represents a halogen atom is produced by hydrogenation of a g -halogenobutyryl halide in solution with a palladium catalyst, the catalytic activity of which has been so reduced by poisoning with a contact poison that the hydrogenation does not proceed beyond the stage of the formation of the desired aldehyde.  Suitable contact poisons include sulphur dissolved in quinoline, arsenic, mercury and mercurous cyanide.  The products may be employed in ring syntheses, e.g. in the production of pyrroline and pyrrolidine by the Grignard or Reformatzky process.  In the example g -chlorobutyraldehyde is obtained by hydrogenating g -chlorobutyryl chloride dissolved in absolute xylene at the boiling point of the mixture under reflux in the presence of a palladium-barium sulphate catalyst poisoned by the addition of 3-5 drops of sulphur dissolved in quinoline, or by traces of arsenic, mercury or mercurous cyanide.

Title: Improvements in apparatus for distributing sand, gravel, and the like material on roads and footpaths
IPC: E01C19/20
Filed: 1928-07-10
Abstract: 317,954. Johnson, A. F. July, 10, 1928. Sand and like distributers.-In a machine for scattering gravel, sand, &c. on roads and paths a rotary distributer is mounted beneath the hopper so that the sand &c. falling through an adjustable slot in the lower end of the front wall of the hopper is delivered on to rotating blades and thus spread over the surface of the road. The hopper e, mounted on a frame a running on ground-wheels b driven by the motor c, is fitted at the bottom with a rotary agitator f which directs the sand &c. through an adjustable slot h on to the blades of the rotary distributer p. These blades may be flat but are preferably curved so that the material is thrown outwards to some extent. Both the agitator and the rotary distributor are driven from the ground wheels through clutches by which the movement may be controlled. A lever i, which can be locked in any desired position on a toothed quadrart j, controls the sliding door g of the hopper through a connecting rod k and cranks m and o, and the projecting portion of this lever i<1> operates clutches 14, 15, controlling the motion of the agitator, through the cord or chain passing round the roller t to the pivoted lever r. When the lever i is pulled back to open the slot of the hopper the cord q becomes slack and the action of the spring s causes the clutches 14, 15 to engage. The same mechanism is employed to operate the clutches controlling the rotary distributer.

Abstract: 886,228. Automatic control systems for aircraft. SHORT BROS. & HARLAND Ltd. Aug. 5, 1959 [June 23, 1958], No. 20102/58. Class 38 (4). In an aircraft automatic stabilizing system, signals from each of a number of gyroscopes responsive to rate of turn about the same axis are integrated, corrected by comparison with signals from a single attitude gyro, and applied to control servomotors driving common stabilizing means. In Fig. 1 electric signals from a potentiometer-type pick-off R 5  associated with a rate of pitch gyro RG are integrated by a motor-type integrator INT 1  the output from a potentiometer R 2  of which is applied, through a limiting amplifier SA, torque motor TM, hydraulic control valve V, and hydraulic servomotor SM, to control the aircraft through a linkage L so as to maintain a desired angle of pitch. Position and rate feedback signals from pick-offs R 4  and VPO operated by the servomotor and control valve respectively are applied to the input of amplifier SA. Signals from pick-off VPO are also applied to a fault detection circuit as described in Specification 853,674. The control system is triplicated, two other channels (II and III, not shown in detail) involving separate rate gyros, integrators, amplifiers and hydraulic servomotors being provided to control linkage L. To monitor the rate gyros electric signals from a single attitude gyro AG are compared with signals from each integrator in drift-controlled amplifiers DCA the outputs of which are applied to the integrators to correct errors developed in the signals from the rate gyros. Manual pitch adjustments are effected by a control column CC operating potentiometers CR 1  to apply signals to amplifiers SA. The differences between signals from a potentiometer CR 2  also operated by the control column and signals from the attitude gyro AG are integrated by a second integrator INT 2  the outputs of which are applied to amplifiers SA to maintain balance during pitch adjustments. In a modification, Fig. 2 (not shown), potentiometer CR 2  is dispensed with and the differences between signals from potentiometers CR 1  and those from integrators INT 1  control integrator INT 2 . Remote control by radio is referred to.

Abstract: 1376876 Data processing systems INTERNATIONAL BUSINESS MACHINES CORP 27 April 1973 [30 May 1972 (2)] 20102/73 Heading G4A An image of each bit in an optically addressed data page contained in a hologram store 20 falls on a photosensitive element associated with the corresponding bit of a page-sized monolithic memory to alter the entire contents of the memory. The hologram store may hold a directory or index file of symbolic names of data sets and respective disc addresses, program segments or microprogram routines as explained in more detail below. The monolithic memory can be an applications program store 14, an operating system program store 15, an associative search array 16, and/or a microprogram store 17 in any of a number of processors 12. A particular page in hologram store 20 is addressed by loading register 22 which controls a laser source and beam deflection arrangements. When a processor 12 requires a particular data set, e.g. insurance rate table, successive pages in store 20 are addressed by incrementing register 22 until the required entry is found by an associative search performed in array 16. The hologram pages are preferably arranged in order of usage frequency. The holograms each have a different pattern superimposed on it for each memory to which the corresponding page may be transferred one or more of the memories being electrically activated or electrically and optically activated to receive a page image. Array 20 may hold high usage system control program segments which can be transferred to store 15 and high usage applications program segments which can be transferred to store 14. Programs written for older types of machine can be executed in the original language by emulation techniques in which the entire contents of a selected microprogram store 17 are changed by array 20 to provide the particular set of routines required for the task or program being executed by the associated processor. The same or different languages can be emulated concurrently by different processors 12. Stores 17 do not need to store all routines of a set at once since subsets can be paged in in one machine cycle, without noticeable degradation of system performance. Modifications.-Multiple stores 14, 15 can be provided, one for each processor 12, several hologram arrays 20 and corresponding search arrays 16 may be provided for operation in parallel or one store 12 can be used to change the contents of a number of arrays 16 or to modify the performance of associative array data processors. The hologram store 20 may be read-write, words from mass storage being set up seriatim in an electro-optical shutter array and transferred to store 20 simultaneously as a page. Preferably a number of pages, e.g. 4, are set up on the shutters and are recorded at a common hologram location for subsequent read-out to separate search arrays 16.
