Title: System for positioning a type carrier
IPC: B41J1/30
Filed: 1978-03-10
Abstract: The device has an electromechanical adjusting gear mechanism for a daisywheel which, on its circumference, bears the types to be printed. The daisywheel driven by means of an electric motor is positioned by means of a ring tabulator. This purpose is served by stops (8) which are controlled by means of keys. In this case, the stops (8) are moved and thus lie within the range of counter-stops (6) which rotate together with the daisywheel (24). When a stop (8) strikes against a counter-stop (6), the rotation of the daisywheel (24) is interrupted. The lower-case and upper-case letters are arranged on the daisywheel on adjacent spokes in each case so that, for switching over from lower-case to upper-case letters, the entire adjustment system is shifted together with the daisywheel by one spoke spacing. <IMAGE>

Title: Improvements relating to the hydrocatalytic cracking of hydrocarbons
IPC: C10G47/12
Filed: 1963-03-12
Abstract: Hydrocracking of C10 or higher n-paraffin hydrocarbons e.g. cetane, is effected with hydrogen at 400-800 DEG  F. in the substantial absence of sulphur with an elemental Group VIII metal catalyst on a refractory support, and a normally-liquid product is recovered. Substantial absence of sulphur is defined as less than 500 p.p.m. by weight, sulphur-containing feedstocks therefore requiring preliminary desulphurization.  The feed may be a single n-paraffin or a mixture from the higher petroleum fractions which may contain up to 10% by weight non-n-paraffin hydrocarbons. The catalyst may contain 5-75% wt. iron group metal, e.g. Ni, Co or 0.01-5% wt. platinum group metal, e.g. Pt, Pd on an inactive or active support such as MgO2, CaCO3, SiO2, pumice firebrick, sepiolite or kieselguhr (the former) or g -Al2O3, SiO-Al2O3, SiO2-MgO2 and zeolites containing 0.1-15% wt. combined chlorine or fluorine (the latter).

Filed: 1964-03-09
Abstract: 1,009,577. Making valves; welding by fusion; straightening. M. H. GROVE. March 9, 1964 [March 25, 1963], No. 9810/64. Headings B3A, B3E and B3R. A plate is welded to a channel-shaped structure to form gate-valve bodies of rectangular cross-section by compacting granular flux in the assembly comprising the plate and the structure and externally welding the longitudinal edges of the plate to the structure. The channel-shaped structure may be a single rolled section or may be fabricated by internally welding angle sections to a plate 10. The structure closed at its ends by tack welded plates 22 having apertures through which are passed hoses 18, 19, Figs. 5, 6. The plate 11 is tack-welded to the structure, and clamps 24 are applied. After inflation of the hoses 18, 19, longitudinal welds 25 are made by a two-headed submerged arc welding machine. The fabrication is now reversed and the plate 10 is similarly externally welded to the angles 12, tack welded plates 26, Fig. 7, serving as flux retainers. The resulting fabrication is cut into lengths and formed with apertures 36, Fig. 8, to constitute valve bodies for use in the fabrication of gate valves, Fig. 10. Sealing rings 45, fluid passages 37, and end assemblies 41, 39 are welded to each body. Straightening.-After each pair of longitudinal welds are completed, the fabrication assumes a bowed shape which during cooling straightens and finally takes up a reverse curvature. To prevent this, the fabrication is held by clamp 61, Fig. 12, on a support 59 in its initial bowed condition while cooling, so that when released it assumes straighteness.

Title: Improvements in or relating to centrifugal casting machines
IPC: B22D13/02
Filed: 1941-08-01
Abstract: 550,997. Casting-machines. JAMES & CO. (BIRMINGHAM), Ltd.; and ANDREWS, H. Aug. 1, 1941, No. 9833. [Class 83 (i)] A centrifugal machine for casting cylinder liners, piston-ring pots &c. having an end plate or ring 16 adapted to be held against the end of the mould 15 during casting and to be moved out of the way during ejection, as described in Specification 418,808, is provided with power means for moving the ring 16 from one position to the other. The mould is carried by arms 14 of a head 13 which can be rotated by a hollow shaft 10 and pulley 12 while the ring 16 is carried by arms 17 pivoted to slides 19 mounted, by means of springs, to allow for expansion of the mould in a head 21. The ring 16, in the "out of the way" position shown in full lines, rests on a plate 30 of arms 31 which are pivoted to fixed brackets 32 and attached by a link 33 to an axially movable screw 24. A reversing motor 74 can be started, by press-button, to rotate a nut 71, Fig. 4, and thus move its screw 34 to the left and the ring 16 up into alignment with the mould, as shown in broken lines. Screws are then rotated by sprockets 42, Fig. 2, to move, to the right, a head 38, bearing 37, shaft 24, head 21, and thus the ring 16, the motor being arrested by a magnetic brake, when the ring clamps the mould, by the action of an adjustable stop 77 on the screw 34. The ring 16 is supported by a plate 28 engaging a plate 29 fixed to the head 13, and is aligned by rods 27 so that the plate 30 can be lowered to allow the mould to be rotated. After casting, the plate is again raised, the ring 16 moved to the left and the plate 30 lowered to a position determined by a second arresting stop 78 on the screw 34. The casting is then ejected by moving a plate 35 to the left by its rod 36, yielding device 46, bearing 43, head 44, and screws 48 rotated by sprockets 49. The stop 78 may also operate a switch in the circuit of the main motor so that the mould cannot be rotated until the ring 16 is in position. Specification 550,996 also is referred to.

Title: Improvements relating to fluid flow control devices
Inventor: SIXSMITH HERBERT
IPC: F16K17/18
Filed: 1958-03-27
Abstract: 870,154. Valves. NATIONAL RESEARCH DEVELOPMENT CORPORATION. June 26, 1959 [March 27, 1958], No. 9869/58. Class 135. A device controlling fluid flow through it in opposite directions has a chamber 1 with two ports 3, 4, an operating member 38 with a valve 13 seating at 3, and a part 7 at port 3 which on initial opening of the valve forms a space 30 with the operating member and has an opening 29 for the passage of fluid from 4 to 3 which is smaller than the flow passage for fluid from 3 to 4 when the operating member is moved to an extreme position, the valve initially opening for flow from 4 to 3 by the application at 3 of a pressure smaller than the pressure at 4. The device is used in a gas regenerator system. With resilient valve 13 closed, a sliding abutment 39 loaded by spring 23 contacts a guide 21 and tends to open the valve. On the application of the pressure at 3 the spring opens the valve, the abutment 39 is held by stem 15 away from guide 21 and fluid flows from high pressure port 4 to low pressure port 3 at a rate determined by opening 29 which may be in member 38, around the edge of member 38 or through wall 7. On decrease of pressure at 3 the flow closes the valve. On the application of a higher pressure at 3 than at 4, the member 38 is lifted against its weight to open a larger flow passage between it and wall 7 for flow from 3 to 4. In an alternative embodiment, the initial opening is limited by a stop on stem 15 engaging guide 21 and opening 29 is in a weight loaded valve seating on member 38 which is provided with a larger opening, the valve being lifted for flow from 3 to 4. The valve may be solid, with the opening 29 in member 38 but outside the periphery of the valve. In a further embodiment the shapes of members 7, 38 are interchanged. The member 7 may be formed by the wall of chamber 1. Specification 842,577 is referred to.

Title: Scraper device for preparing cinematograph films for splicing
IPC: G03D15/04
Filed: 1961-03-17
Abstract: 968, 099. Film scraper devices. H. NORDHOFF, and F. WINTZER. March 17, 1961 [March 24, 1960] No. 9927/61. Heading G2C. In a device for scraping the ends of film strips prior to splicing them together, the scraper means is reciprocable transversely to the film, and also movable as a whole under spring loading towards the film. In the form shown, the device comprises two parallel guide bars 3 (only one shown in Fig. 2) hinged at 2 to a base-plate 1. Between the bars 3 is mounted a carriage 10 carrying two scraper blades 13. The carriage slides between the guide bars, and is guided in its traverse by pins 11 which engage in slots 12 in the bars 3. The central part of the carriage 10 has a projection 10a extending upwardly into a recess 18 in the handle 19. A pin 20 in the handle passes through a vertical slot 15 in the part 10a, so that there is a limited amount of vertical play between carriage and handle. A curved blade spring 16 is also accommodated in the recess 18, its outer ends 17 bearing on the upper surface 10b of carriage 10. By pressing the handle downwards against the top of the guide bars 3 (from which it may be separated by a protecting plate 21), the only force transmitted to the carriage 10, and hence the scraper blades 13, is the uniform stress due to the spring 16. The handle is then slid forwards and backwards, so that the spring- urged scraper blades 13 engage against the ends of the film strips which are clamped between the pairs of plates 6, 7 and 8, 9.
