Patent GB-765291-A (GB)
IPC: G06C23/02
Abstract: 765,291. Calculating-apparatus. NATIONAL CASH REGISTER CO. March 30, 1955 [May 18, 1954], No. 9232/55. Class 106 (1). The repeat control of a calculating machine has two operative positions: in one it prevents cyclic release of the amount keys so that repeat entries can be made by operation of the motor bar; in the. other it also causes continuous cycling without the necessity for using the motor bar. As shown, the repeat control takes the form of a finger-piece 35, Fig. 2, slidably mounted on the machine key plate 36 for rear.- ward or forward movement from the neutral position shown, these movements rocking a cam and detent plate 37 clockwise or counterclockwise respectively. In normal cyclic operation, with the repeat control 35 and the plate 37 in their normal positions shown, a key restoring lever 14 is rocked first clockwise and then counterclockwise under the control of a stud 17 on a plate 18 secured to an oscillating main shaft 19. In its clockwise movement, a pawl 21 on the lever 14 wipes idly past a stud 22 on a key-restoring bail 13 and rocks the bail to release depressed keys upon its return movement. When the repeat control 35 is moved to its forward operative position, a cam part 41 of the plate 37 is positioned over a stud on the key restoring lever 14. This prevents movement of the lever 14 so that actuated amount keys 12 remain depressed for repeat cycling under control of the motor bar. When the repeat control 35 is moved to its rearward operative position, a stud 50 on the plate 37 similarly blocks the key restoring lever 14, to retain actuated amount keys depressed, whilst the plate 37 itself depresses a lever 38 pivoted at 15, the lever 38 rocking a bell-crank 44 which actuates the machine release trip member 11 through a resilient connection 46. This results in continuous cycling of the machine and repeated entry of the set amount until the repeat control 35 is released for return to its intermediate position by a spring 40 interconnecting the plate 37 and lever 38.

Patent GB-2029604-A (GB)
Title: Hydraulic ramping circuit for control valve
IPC: G05D9/04
Filed: 1978-09-06
Abstract: A hydraulically actuated control valve 33 normally includes a hydraulic cylinder 19 which has an internal piston 20 connected through a shaft 25 to the actuating mechanism in the control valve. Ports 17, 18 are provided on each side of the piston 20 through which fluid flows to move the piston axially inside the cylinder. The piston can be controlled by an electro-hydraulic servo- controlled valve 10 which includes an electrical input 11, a mechanical feedback input 12, and first and second outputs 13, 14. The outputs 13, 14 are connected to the two ports 17, 18 in the cylinder 19, a mechanical feedback 12 is coupled to the shaft and the mechanical feedback input of the control valve, and an electrical circuit 40 is coupled to the electrical input 11 of the servo- controlled valve 10 to signal the hydraulic portion of the valve to either move the shaft in a manner to close the valve or move the shaft in a manner to open the valve. An improved control apparatus is provided which serially connects a solenoid valve 61 in one of the lines of the hydraulic output 13 of the servo-controlled valve 10 with one of the ports 17 in the cylinder 19. The solenoid valve 61 can be bypassed with a needle valve or a controllable valve 64. A mechanical actuator 57 on the shaft is coupled through an electrical circuit 59 to the solenoid valve 61. Thus, if the valve is signalled to close at a high rate of speed at a predetermined time, the mechanical circuit will trigger the solenoid valve 61, causing the speed to diminish to a preselected rate in order to prevent water hammer. <IMAGE>

Title: Processes for the Production of Tin Oxide Coatings and Articles Having Such Coatings
IPC: H01L31/04
Filed: 1978-10-20
Abstract: Electrically-conductive films of fluorine doped tin oxide are prepared by a novel process utilizing gaseous chemical compounds which react to form a tin-fluorine bond at a temperature which is (1) high enough so that the newly-created tin-fluorine bond-bearing molecule remains in the vapor phase; and (2) low enough so that oxidation of the molecule occurs only after the indicated rearrangement. Films prepared by the process of the invention are characterized by surface resistances as low as 1 ohm per square when the film thickness is as thin as about a micron. These films are also characterized by extremely good reflectance of infrared radiation.

Title: A belt and friction drive mechanism
IPC: F16H13/02
Filed: 1979-02-16
Abstract: A belt-drive mechanism comprises a driven pulley 10 mounted on a fixed axle 14 and a driving pulley 11 and an intermediate idler pulley 12 each mounted on axes 15, 16 which are movable relative to the driven pulley. A high tension belt 19 encompasses the driven and driving pulleys and is tensioned to about one third of its ultimate tensile strength ie far in excess of that used in conventional belt drives. The tension pulls the driving pulley and the idler pulley hard against each other and against the driven pulley such that a rotational input to the driving pulley is applied to the driven pulley in part by the frictional drive of the pulley train and in part by the frictional belt drive. The provision of the floating axles for the driving and idler pulleys ensures that none of the belt loading is applied to the axle of the driven pulley or the structure in which it is mounted. <IMAGE>

Title: Unit for viewing areas with limited access
IPC: G02B7/182
Filed: 1981-03-17
Abstract: Scanner units for investigating areas to which there is limited access often have a small reflector at the end of a stick and are held so that a person can see underneath the item to be inspected.

A lamp (34) is carried by the shaft for illuminating dark areas. In order to diffuse light from the lamp, the lamp may have a diffusing lens and may point towards the reflector so that reflected light is projected at the area to be inspected. <IMAGE>

Title: Preparation of 1,1,1,3,3,3- hexafluoropropane-2-ol by Vapor Phase Hydrogenation of Hexafluoroacetone with Nickel Catalyst
IPC: C07B61/00
Filed: 1981-03-19
Abstract: A process of preparing 1,1,1,3,3,3-hexafluoropropane-2-ol by vapor phase catalytic hydrogenation of hexafluoroacetone with hydrogen gas, characterized by the employment of a catalyst containing metallic nickel as its essential component.

Filed: 1981-07-13
Abstract: A method of ascertaining a proportional reproduction factor comprises attaching an elastomeric band (18, Figure 1), on which percentage markings (34) are imprinted, to a dimensionally-marked scale (24) or ruler. The zero- percentage end (16) of the band is fixed to the zero-measure end (22) of the scale, and the band is stretched until the end thereof (16a) opposite the zero-percentage end is juxtapositionally aligned with a scale marking representative, for instance, of the actual or starting size of the subject matter (i.e. three-dimensional object, copy, artwork, photograph, etc.) With the band thus stretched, the scale marking for the desired reduction size of the subject matter is noted, as well as the band percentage marking which is juxtapositionally aligned therewith. The latter percentage marking, then, is the factor to be used in the reproduction of the subject matter. The method comprises a corresponding process for ascertaining the factor to be used in enlargement of the subject matter. The apparatus (10) of the invention, usable in the above methods, comprises an expansible element (18) having incremental, reproduction- percentage graduation indicia (34) thereon. <IMAGE>
