Title: Push button telephone instruments
IPC: H04M1/31
Filed: 1973-06-08
Abstract: 1411910 Number sending devices; telephone instruments PYE Ltd 15 Feb 1974 [8 June 1973] 27392/73 Headings H4K and H4J In a push button telephone instrument, depression of any push button causes the operation of a contact via a mechanical link and the contact is held in the operated position by means of a latch which is released either by replacement of the handset or by the operation of an electromagnet. Push buttons 35 are associated with electronic circuity 3 for producing loop disconnect dialling pulses as in Specification 1,195,141 or alternatively multifrequency tones and each button is coupled mechanically to a member 18 for operating the various off-normal contacts 11-17. With the handset on-hook the various mechanical members are positioned as shown. When the handset is lifted the cradle hook 25 pivots to bring its end 28 into contact with block 31 and latch 36 pivots under the action of spring 23 to keep its end 24 in contact with end 28 of the cradle hook. If a push button is now depressed member 34 moves laterally to displace member 18 to the right such that projection 19 moves along surface 36 of the latch and finally latches against surface 22, thereby holding the contacts 11-17 operated. At the end of the dialling sequence other electronic circuitry 3 causes an electromagnet 32 to operate causing latch 36 to pivot clockwise and to release the projection 19. The contacts return to the unoperated state and remove the short circuits on the transmitter and receiver. Should the subscriber replace his handset before the dialling sequence is completed, end 28 of the cradle hook causes the latch to be released.

Patent GB-1081873-A (GB)
Title: A method of filling tubes
Inventor: DAIN RICHARD JAMES
IPC: B01J8/00
Filed: 1964-07-03
Abstract: In a method of catalytic steam-reforming liquid and gaseous hydrocarbons in an externally heated tubular reformer, the tubes are filled with particulate catalytic material by delivering air to the lower ends of the tubes under such a pressure as to retard the fall of the material, which is supplied to the top of the tubes.  The tubes may be emptied by the same method.  The apparatus is that described in Specification 1,036,447, the catalyst lying in the annular space between the tube and an internal axially disposed pipe which opens near the bottom of the tube, which is closed at its lower end.  The pipe serves to deliver air to the tube during filling and emptying.

Title: Improvements in or relating to repeater-type, cocking-firing mechanism for firearms
IPC: F41A19/40
Filed: 1961-07-28
Abstract: 998,899. Firing mechanisms. RHElNMETALL G.m.b.H. July 28, 1961 [July 29, 1960], No. 27515/61. Heading F3C. Relates to a firing mechanism for ordnance in which the striker is cocked and released for fiiring by operation of a firing lever. According to the invention, a single spring 11, Fig. 1, serves to cock the striker 3 and to return it after firing to its initial position shown, the spring 11 being located between two abutments 13, 12 which are movable towards each other on actuation of the firing lever 17 to cock the striker as shown in Fig. 2, the spring 11 then being released to project the striker into its firing position from which it is carried back to its initial position by the spring. Mounted on the rear end of the striker 3 is a cocking piece 6 provided with a cocking latch 7 having two projections 8, 9. The cocking piece 6 also contains a pressure pin 10 which, in the inoperative position shown in Fig. 1, abuts the projection 8 and a disc 13 placed loosely on a pressure member 14 which is loosely mounted on the striker 3. The spindle of the firing lever 17 is formed with a projection 20 which bears against the pressure member 14 and with a projection 21 adapted to engage the projection 9 of the latch 7. When the lever 17 is pulled back by means of a firing lanyard 19, the projection 20 urges the pressure member 14 and disc 13 forwardly, whilst the projection 21 engages the latch projection 9 to move the cocking piece 6 and striker 3 rearwardly which carries with it the sleeve 12 serving as abutment for the spring 11, whereby the spring is tensioned. When the spring 11 is fully tensioned, as shown in Fig. 2, the projection 21 slides over and beyond the projection 9 so that the striker flies forwardly to the firing position. After firing the spring 11 expands rearwardly, to return the lever 17 to its initial position, and the returning pressure member 14 urges the cocking piece 6 to the left, whereby the striker is returned to the initial position. At the same time the pressure pin 10 engages the projection 8 to bring the projection 9 of the latch 7 in front of the spindle projection 21 so that all parts are automatically restored to their original positions ready for the next firing.

Abstract: 366,105. Hydraulic servomotor apparatus. THOMAS, H. K., Pines Edge, Sandy Lane, Cobham, Surrey. Sept. 18, 1930, Nos. 27972 and 28783. [Class 69 (ii).] A variable-speed gear control comprises a fluid-operated servomotor which imparts necessarily step-by-step displacements to a mechanical control member. The servomotor 13, Fig. 2, is controlled by a central valve 37 which is angularly displaced by a lever 50. A lay-out upon a vehicle is shown in Fig. 1. The lever 50 is operated by a governor 22 driven through a flexible shaft 23 from the propeller shaft 24. Fluid is sent to the motor 13 through a duct 15 from a pump 14, and returns by a duct 17 to a storage tank 18. The motor effects stepped displacements of a rack 12,. which turns a cam shaft 7 controlling epicyclic or other variable gearing in a casing 1. The motor comprises a cylinder 26, Fig. 2, containing- a piston 25 adapted to reciprocate and to carry with it a tubular piston rod 27 fast to the rack 12. The tubular valve 37 within the piston rod 27 is divided by a longitudinal wall 41 into a chamber 42 receiving fluid from the duct 15 and a chamber 43 delivering to the duct 17. In Fig. 4, valve 37 has been turned to bring supply port 51 under piston port 35 and exhaust port 53 under piston port 34. The parts 25, 27, 12 move one step to the right and stop in the definite position shown in Fig 5. If then valve 37 is turned afresh to bring its supply port 52 under piston port 35 and its exhaust port 54 under piston port 34, the piston moves a second and final step to the. right and stops at the chain line. Other pairs of ports effect the backward steps. In the arrangement shown, adapted for governor control, the ports are placed so that the shifts to middle speed take place at different speeds of the governor according to whether the change is being made up or down.

Abstract: Heptan - 3 : 4 - dione and alpha - ethyl - beta - propyl-acrylic acid are prepared by oxidizing alpha-ethyl-acrolein in the liquid phase at a temperature below 100 DEG  C., e.g. between 40 DEG  and 60 DEG  C. or 50 DEG  and 55 DEG  C. and separating the heptan-3 : 4-dione and alpha-ethyl-beta-propyl-acrylic acid from the reaction mixture, e.g. heptan-3 : 4-dione is recovered by distillation or heptan-3 : 4-dione is recovered by distillation at atmospheric pressure and alpha-ethyl-beta-propyl-acrylic acid by distillation at reduced pressure.  The oxidation may be continued until not more than 80 per cent by weight of the alpha-ethyl-acrolein is oxidized so that the reaction mixture contains not less than 20 per cent by weight of unchanged aldehyde.  The reaction may be effected by continuously feeding alpha-ethyl-beta-propyl acrolein to a reactor and withdrawing the reaction mixture continuously thereform, e.g. the reaction mixture may contain at least 20 per cent by weight of alpha-ethyl-beta-propyl acrolein.  The alpha-ethyl-beta-propyl acrolein may be prepared by condensing butyraldehyde in the presence of dilute alkali at 50 DEG  C. and recovering the fraction boiling between 172 DEG  and 175 DEG  C.  In an example, alpha-ethyl-beta-propyl acrolein is reacted with molecular oxygen at 50 DEG  C. and the product fractionated to yield heptan-3 : 4-dione and alpha-ethyl-beta-propyl acrylic acid which may be converted into its anhydride, anilide or ethyl ester.
