Title: Improvements in typewriting machines
IPC: B41J19/18
Filed: 1931-11-30
Abstract: 381,762. Typewriters. JAMES, R. W., 11, Queen Victoria Street, London.- (Remington Typewriter Co. ; Ilion, New York, U.S.A.) Nov. 30, 1931, No. 33127. [Class 100 (iv).] Line-locking devices; space-key actions.-The line-locking device is arranged to disable the connections between the escapement mechanism and an actuating-key, for instance the spacekey, the arrangement preventing the parts from being strained if the actuating-key is depressed when the machine is locked. The actuating-key may have a trip-member which is disconnected from the escapement mechanism at each operation and also on operation of the line-locking device. The machine shown in part in Figs. 2 and 4 embodies the framework and type-lever action described in Specifications 372,465 and 372,477, and escapement mechanism comprising a rocker 31 trunnioned at 32 to a bracket 28 on the vertically shiftable bed 29 of the carriage 40, dogs on the rocker co-operating with an escapement wheel provided with a pinion 36 co-operating with a rack 37. A universal bail 21, arranged in the path of heels on the type-levers, is pivoted at 22 to the framework and is connected by a link 25 to a bell-crank 26 which is pivoted at 27 to the bracket 28 and has a screw 30 abutting on the rocker. A line-locking stop 82 on the carriage co-operates with a lug 81 on a rocking arm 78 engaging an arm 89 pivoted at 90 on the framework. When the stop engages the lug, the arm 89 moves beneath a lug 92 on the universal bail, and the type-levers are thereby prevented from operating the escapement and from reaching the printing point. The arm 78 is pivoted at 79 to a shaft 80 which can be rocked by means of a key 87 to release the lock. The space-key is secured to a shaft having an arm 55 provided with a spring-urged trip-lever or bell crank 57 which normally abuts on a lug 67 on the universal bail, and on a cushion-stop 63 carried by a finger 95 on the arm 89. An adjustable eccentric-stop 69 is arranged in the path of the arm 58 of the bell crank. When the spacekey is depressed, the universal bail is rocked to operate the escapement, and the stop 69 subsequently rocks the bell crank and releases it from the lug. The universal bail is thereby disconnected from the space-key and can return to normal position for operation by the printing-keys, even if the space-key is held down. When the line-locking device is operated, the stop 63 displaces the bell crank, and if the space-key is depressed strain is not transmitted to the universal bail or space-key connections. The stop 63 may consist of a closely-wound spring or a felt pad. In another arrangement, the bell crank has a shoulder and a felt pad engaging the lug 67, and the finger 95 has a lug having slight lost-motion engagement with the bell crank. '

Title: Improvements in preparation of acetylpropyl chloride
IPC: C07C45/67
Filed: 1945-12-07
Abstract: Acetylpropyl chloride is produced by reacting acetylbutyrolactone with aqueous hydrochloric acid in substantially mol. for mol. proportions at the boiling point of the mixture, withdrawing and condensing the vapour, and separating the acetylpropyl chloride from the condensate.  In an example, aqueous hydrochloric acid and acetylbutyrolactone are placed in a flask fitted with a two-plate bubble cap fractionating column, condenser, separator and seal to permit continuous return of the water layer from the separator to the column.  The contents are heated to boiling and then acetylbutyrolactone and hydrochloric acid are fed separately into the flask in mol. for mol. proportions.  The condensed distillate flows into the separator where the acetylpropyl chloride separates as the bottom layer and is continuously withdrawn.  The acetylbutyrolactone may be prepared by reacting ethylene oxide with ethyl acetoacetate as described in Specification 601,802.  Specification 558,286 also is referred to.

Title: Hose coupling
IPC: F16L37/00
Filed: 1966-07-29
Abstract: 1,122,737. Hose couplings. FORD MOTOR CO. Ltd. 29 July, 1966 [24 Oct., 1965], No. 34077/66. Heading F2G. In a hose coupling wherein male and female parts 11, 10 having spring-loaded check valves which are opened by connecting the parts and close automatically upon disconnection of the parts, the parts being retained in the connected condition by balls 17 held in apertures 16 in the part 10 and engaged in a groove 19 in the part 11, the coupling is mounted on a channelshaped member 27 connected to a support 40 on a tractor and by a spring-loaded bolt 41, whereby the coupling may swivel or rock on the support in response to a sideways or vertical pull on the hose. A spring-loaded sleeve 20 which retains the balls in the groove 19 when the coupling parts are connected is secured to the member 27 and upon excess pull on the hose due to a trailed implement becoming mechanically uncoupled from the tractor the part 10 moves rearwardly relative to the sleeve so that the balls move into the groove 24 to release the part 11. To manually connect and disconnect the coupling parts, a lever 34, bifurcated to engage and prevent rotation of the part 10, is depressed to engage and move that part rearwardly with respect to the sleeve, whereby the part 11 may be inserted into or withdrawn from the part 10. The latter comprises inner and outer portions 12, 14, so that, to unseat the check valves when fluid under high pressure is contained in the hoses 25, 26, the part 14 is partially unscrewed to permit the coupling parts to be connected and then again screwed fully into the portion 12.

Title: Method and Means for Preventing Fouling of Metal in a Marine Environment
IPC: C23F13/02
Filed: 1968-07-17
Abstract: 1,176,274. Preventing fouling of metal in sea water. LOCKHEED AIRCRAFT CORP. July 17, 1968 [July 20, 1967], No.34134/68. Heading C7E. Fouling of metal structures immersed in sea water is prevented by coating said structures with a metal toxic to such marine organisms as cause fouling, anodically dissolving said toxic metal while said structure is substantially at rest in the water, and cathodically protecting said metal when said structure's movement in the water precludes such fouling. The toxic metal may be cadmium to which 0.1 to 0À3 wt % of tin is added, or zinc to which 0.1 wt % aluminium and 0À 05 wt % cadmium are added. Fig. 2 shows, diagramatically, a ship's hull 1 with a toxic coating 2. When the ship is in motion and fouling is unlikely, a cathodic system 5 is energized by switch 7 so that the hull coating is made cathodic with respect to the permanent anodes 6, so that corrosion of the hull and coating is prevented. When the ship is liable to fouling, switch 7 is moved to energize power source 3 which acts in conjunction with auxiliary electrodes 4 to dissolve the toxic coating 2 at a suitable rate.

Title: Improvements in or relating to fluid pressure valves
Inventor: PAUL WALTER JOHN
IPC: F16K39/02
Filed: 1958-10-27
Abstract: 905,024. Valves. AVIATION, MINISTER OF. Jan. 15, 1960 [Oct. 27, 1958], No. 34328/58. Class 135. A fluid valve comprises an obturating member 11 having a hollow chamber 15 in which is housed a piston-like member 14 provided with supporting legs 16. A flexible resilient diaphragm 18 may be clamped to the valve head and is dished so that in its free condition its centre portion will take up a position in an opposite sense to that shown. The chamber 15 is connected by passages 21, 22 to the upstream and down stream sides of the valve respectively. In operation with the valve closed inlet fluid pressure acts on the valve to hold the obturating member 11 on the seating 23 and at the same time the piston-like member 14 is moved towards the valve seat by the inlet fluid pressure acting through passage 21 on the diaphragm 18, thus the inlet fluid pressure acting to hold the obturating member 11 in. the closed position is only effected over an annulus of area defined by the area of the circle of contact at 25 less the area of the piston-like member 14. During the initial opening of the valve the legs 16 are held in contact with the valve body 24 as a result of the difference between the inlet and outlet pressures and the spring force due to the diaphragm 18. The inlet fluid pressure above the diaphragm 18 is subsequently balanced by that below the pistonlike member 14 acting through the passage 22 when the back-pressure below the member 14 builds up to the same value as the inlet fluid pressure. To provide a rapid build-up of back pressure down stream of the obturating member a sleeve-like member 26 connected to the valve spindle 12 is provided with a port 31 which, in the fully-open position of the valve, is coincident with a port 30. Specification 690,945 is referred to.

Title: Hydraulically-damped sliding doors with electro- mechanical driving means
IPC: E05F15/56
Filed: 1972-07-24
Abstract: 1368218 Electrically operated sliding doors VEREINIGTE BAUBESCHLAGFABRIKEN GRETSCH & CO GmbH 24 July 1972 14 June 1972 34428/72 Heading E2M A sliding door, in which two leaves 5, 6 are moved on a rail 2 by an electric motor 12 acting via a belt 7 mounted on pulleys 8, 9, is connected to drive a device which, on each opening or closing movement of the door, moves fluid through one of two pairs of series cnnected flow restrictors in a hydraulic circuit, a valve providing a short circuit for one restrictor in each pair for most of the opening or closing but being operated by a door actuated switch to close the short circuit and damp motion toward the limit positions. As shown the pulley 8 is driven by the electric motor and the pulley 9 drives a hydraulic pump 14 which, depending on the direction of motion of the door, forces fluid through flow restrictors 34, 36 or 35, 37. Restrictors 34, 35 are adjustable to vary the normal speed of the door, restrictors 36, 37 provide adjustable damping near the limit positions, and a magnetic valve 42 either blocks or allows passage through lines short-circuiting the latter. Limit switches 64, 67 are actuated by a projection 82 on leaf 5 of the door control the operation of the valve 42; limit switch 62 switches off the motor in the fully open position and reverses its operation after a time delay; and limit switches 65, 63 can be switched in to penform the functions of switches 64, 62 respectively if only partial opening of the door is required. Limit switch 66 prevents operation of the automatic opening mechanism (described below) when the door is fully closed. In modifications a piston and cylinder mechanism replaces the hydraulic pump 14 and a pair of additional flow restrictors (94, 95, Fig. 19 not shown) are placed in parallel with restrictors 36, 37 to replace the valve 42 and are separately switched by devices on the door. The opening flow restrictor is switched for partial opening of the door also but when not required a valve (97) operates to by-pass the opening restrictor. The motor remains on while the doors are closed but a helical spring mechanism (Figs. 4, 5 not shown), driven, by  a shaft from the motor, is wound up as the door closes and operates to open the door in the event of a current failure. The doors can be locked in the closed position by an electromagnetically movable latch (Figs. 6, 7 not shown) which is retained by permanent magnets in the locked position until released electromagnetically or by hand. A safety device is provided to stop the doors closing and initiate an opening movement in the event of an obstruction and is operated when a control circuit senses that the interval between pulses emitted in response to door movement exceeds a predetermined value. The preferred form of pulse generator (Fig. 8, not shown) comprises a disc (29) driven by the belt 7 and carrying a number of iron pins (30) which are moved past an inductive device as the disc rotates to cause pulse generation.
