Title: Liquid measuring device provided with a continuous counter
IPC: G01F9/00
Filed: 1929-02-14
Abstract: 306,454. Sauser Akt.-Ges, (Assignees of Bovard, F.). Feb. 20, 1928, [Convention date]. Impulse and reaction meters; governing and regulating.-Withdrawal of an exact quantity is facilitated by means dependent on the obstruction of flow. The outlet nozzle 7 is for this purpose fitted with a spring-pressed valve 21. The inlet pipe 1 communicates with a cyinder containing a piston 3, while the outlet from the counter 8 may be closed by a piston-valve 5. Depression of the handle 14 lifts the valve stem 15; a catch 13 engages under the head 17 and withdraws an arm 12 from a notch 10 on the counter disc. 9. A catch 18 retains the arm 12 in lifted position until the valve 21 is pressed to restrict the flow. This restriction causes the piston 3 to rise, tilts the catch 18, allows arm 12 to fall and pulls the catch 13 from the stem 15, thus allowing the outlet valve 5 to close. The release of the catch 13 is however dependent on the engagement of the arm 12 in the notch 10 which corresponds to one of the unit indications of the counter, and supply is stopped only when an exact amount has passed through the apparatus. 307,497. Montelius, C. O. J. March 9, 1928, [Convention date]. Movable-abutment type.-In a rotary pump or motor of the meshing screw type comprising a power screw and a co-operating screw housed in a tightly fitting casing, the area of the axial projection 8, 3, 6, 7, 8 of the groove of the cooperating screw is made equal to the lens-shaped area 1, 3, 5, 7, 1 over which the circles defining the casing contour overlap. The power screw provides the major portion of the work and alone has a drive shaft. The pitch of the threads is suffciently large to permit one screw to drive the other without the necessity of additional gearing. Specification 231,865 is referred to.

Title: Improvements in or relating to means for tuning hollow resonators
IPC: H01J25/24
Filed: 1942-04-15
Abstract: 578,840. Coilless resonators. HOLMAN, H. E., and BARFORD, N. C. April 15, 1942, No. 5005. [Class 40 (iii)] An electrical resonator is tuned by differential screw mechanism which deforms the resonator. The invention is described with reference to a resonator employed in an electron discharge tube, but is applicable to other resonators. In the form shown in Fig. 1, the resonator comprises thin copper discs 3, 4 sealed into and extending outside the discharge tube 1, the external portions, which are clamped to a support 15, being formed with annular parts approaching each other to provide localised capacity which is changed by deformation of the upper disc 4. The annular part of the lower disc is reinforced by a ring 11. The annular part of the upper disc is engaged by ring 8 connected by links 9 to a disc 10 threaded to receive a screwed portion 18 of an adjusting spindle, the upper portion of the spindle being screw-threaded at 12 to engage a sleeve 13 which is also screw-threaded in the cap 14 of support 15. If sleeve 13 is held by disc 20 and knob 17 operated to turn the spindle, disc 10 is 'moved axially a distance of .0005" for one revolution of the spindle if the upper and lower threads on the spindle have pitches of .03125" and .03175" respectively. If the disc 20 is rotated through one revolution and the external pitch of the sleeve 13 is .025", disc 10 is moved .00625" if knob 17 is held or .00675" if spindle 12 turns with the sleeve. Knob 17 and disc 20 provide fine and relatively coarse adjustment, it being substantially immaterial whether knob 17 is held or not for the coarse adjustment. Back-lash is avoided by spring 19. In Fig. 2, employing the same type of resonator, the annular part of the upper disc carries an upstanding ring 30 secured to a further ring 31 connected by three lugs 32 to another ring 33 which is adjustably secured at diametrically opposite points by screws 34, for initial adjustment, to a plate 25 surrounding the tube 1. The plate 25 is carried at one side on pillars 26 and is reduced at 29 to provide pivotal action, whereas its other side is forked and engaged by lugs 23 on each side of a nut 22 carried on a screwed adjusting spindle 21 which also screws on to a fixed screw 36 of different pitch.

Title: Coin actuated timing mechanism for controlling the duration of playing time of indoor games known as bar billiards, and other table ball games
Inventor: SAMS RONALD GEORGE
IPC: G07F17/38
Filed: 1950-03-01
Abstract: 709,182. Coin freed apparatus for controlling the hiring of bar billiards and like games. SAMS BROS., Ltd. March 28, 1951 [March 1, 1950], No. 5180/50. Class 27 In a table ball game such as bar billiards the apparatus illustrated controls the duration for which the balls are made available. When an operating bar 3, Fig. 1, is pulled out after insertion of a coin it draws with it a slide 18 which is subsequently returned by a spring 23 under the control of timing mechanism 20 until, at the end of its movement, an adjustable member 38 on it moves a catch 29 against the bias of a spring 32 to release a bell-crank trigger 34 which then allows a flap (not shown) to prevent return of balls which pass out of play. The catch 29 is pivoted at 30 to the operating bar 3 so that when the operating bar is returned by a spring 6 after being pulled out a flange 31a engages an upstanding part 33 of the trigger 34 to turn the trigger about a pivot below the base plate 1 and hold it in a position in which the flap does not obstruct the return of balls to the player. The slide 18 derives its setting movement from a member 16 secured to the bar 3 and engaging a pin 17 on the slide and, at the end of its return movement, engages a flange 37 on the catch 29 to withdraw the flange 31a from engagement with the upstanding portion 33. Fly nuts 28 on the pallet 25 of the timing mechanism allow the speed of return of the slide to be adjusted. A full stroke ratchet and pawl mechanism 21, 22, Fig. 5, ensures a full stroke of the bar 3. Coin action, thrust: coin prevents engagement of detent. A coin C, Fig. 5, delivered from a shoot 13 to a 'slot 15 in the bar 3 prevents a detent 10 from engaging a notch in the bar. Coin discharging mechanism. As the bar 3 is pulled out a pin 15a (Fig. 6) is slid in a bore in the bar 3 against the bias of a leaf spring 15d by engagement with a cam track 15c on the casing until a notch 15b registers with a slot 15 to allow the coin C to fall to the cash box

Abstract: 216,215. Boothby, F. L. M. Feb. 23, .1923. Aerostats.-An airship having the gas bags surrounded by an enclosed space filled with motor exhaust gases, is provided with means for introducing air into the enclosed space to make up for the deficiency of inert gas due to a sudden descent or to sudden cold, the air being subsequently driven out through valves in the upper part of the envelope by the introduction of a fresh charge of exhaust gases into the lower part of the envelope. The gases may be cooled before entering the envelope by using them for cooking and heating, or by passing them through a thin chamber having one wall exposed to the propeller blast. Fig. 1 shows a rigid airship in which gas chambers A are surrounded by a space C filled with exhaust gases from a conduit E. The gas chambers have relief valves A<1> opening into trunks A<3> leading to the outer envelope and provided at their lower ends with extensions A<4> to give access to the valves A<1>. Manoeuvring valves A<2> are provided in passages A<5> leading to the outer envelope. Non-return valves C<2> enable air to enter the space C when the inert gas contracts, and lightly loaded valves C<1> permit the air to escape when more gas is introduced. The valves may be arranged in the lower part of the envelope if they are connected by trunks to the upper part of the space C. In semi-rigid and non-rigid airships where the space C must be kept above atmospheric pressure, the valves C<2> are replaced by passages leading to the rear of the propellers or to blowers, and the valves C<1> are more heavily loaded. Fig. 7 shows a thin chamber, formed between two plates M, M<1>, through which the exhaust gases are passed to the chamber C. The wall M<1> forms part of the outer envelope exposed to the propeller blast, and the inner wall may be lagged. Condensation products may be removed at N.

The pistons in the units A, E have each three axially-spaced lands 2a, 2b, 2c, and the pistons in the units B, C, D have each two lands 8a, 8b. In the operation of the system lubricant supplied continuously or intermittently is conducted through passages 3, 3a. Lubricant passing through the passage 3a flows through passages 3c, 1f and 5a to the right-hand side of the cylinder in the unit A, whereby the piston 2 therein is moved to the left, to the position shown, displacing lubricant through port 1b, passage 5, port 1e and passage 4h to lubricating point N. Lubricant flows through passage 3, port 1g, passage 6a and port 7h to move the piston 8 of unit B to the left, displacing lubricant from the opposite end of the piston to lubricating point G. Port 7g of unit B is then open to the incoming lubricant so that lubricant can flow through passage 6a to the unit C, causing the piston thereon to move to the left and displace lubricant to lubricating point H. The port 7g of unit C is now open, whereby lubricant pressure moves the piston 8 in unit D to the left, displacing lubricant to lubricant point I. Port 7g of unit D is now open, whereby lubricant pressure moves the piston of unit E to the left, displacing lubricant to the lubricating point J. Port 3a is now in communication with port 1g and passage 5 so that lubricant under pressure flows to the lefthand end of the bore of the unit A, whereby the piston 2 of this unit is moved to the right, displacing lubricant through the lubricating point K. The pistons of the other units B, C, D and E are in turn moved to the right, causing respectively discharge of lubricant to lubricating points L, M, M and J and completing the cycle. The piston of unit A is provided with ah extension 2d which indicates the completion of a cycle of lubrication. The extension may operate a contact for an electrical timer of a pump-driven system. Similar indicator extensions may be provided on all the pistons.
