Title: Improvements in alternating current mercury vapour apparatus
IPC: H01J61/30
Filed: 1927-03-18
Abstract: 290,403. Reynolds, F., and Lees, A. L. March 18, 1927. Low - pressure metallic - vapour apparatus. - In alternating-current mercury-vapour apparatus of the vacuum type with a cathode at one end and two anodes at the other, a small channel or gutter 13 is formed in the bottom of the tube, starting at the mouth of the passage 5 leading to the cathode 6 or, if no such passage is used, at the end of the cathode itself, and extending to the point where mercury returning to the anodes will divide during starting by tilting. The tube may be of U-orV- shape with the limbs close together and with anode vessels 3. 4 close together and parallel or at a small angle to each other, the channel 13 extending across the join of the limbs. During starting by raising the anodes and then lowering them to allow the mercury to return to the anodes, the volume of mercury in the channel 13 is in connection with the cathode and an arc is struck between this small volume and one of the two equal streams of mercury flowing to the anodes, the mercury in the channel quickly vaporizing. Short-circuits between the anodes are prevented. The tube may be of quartz with the channel 13 formed after the apparatus has been shaped.

Title: Pressure responsive antipumping control system for electric circuit breakers
IPC: H01H33/32
Filed: 1954-03-16
Abstract: 757,123. Automatic circuit breakers; switches partly electromagnetic. ALLISCHALMERS MANUFACTURING CO. March 16, 1954 [March 16, 1953], No. 7647/54. Class 38(5) An antipumping, trip-free control system for a circuit-breaker 3 having contacts 4, 5 comprises a closing switch 54 which completes a circuit from power supply 58, through contacts 90, 91 of a reservoir-pressure responsive switch 92, switch contacts 76, 78 which are closed when the breaker is open, contacts 55, 56 of a cut-off switch 57 of the type described in Specification 756,592 and a coil 41 of a solenoid valve 36. Valve 36 is thus opened and admits gas to fluid motor 1 which moves piston 30 and attached rod 37 upwards to actuate bell crank 10 to close the breaker, latch 13 holding it closed against spring 6. Gas in motor cylinder 27 also closes contacts 51, 52 of switch 47 in order to maintain the coil 41 energized, even though switch 54 is released, over a holding circuit through conductors 99, 100. As piston 30 of motor 1 reaches breaker-closed position, an orifice 63 is uncovered and gas actuates the piston 59 of switch 57, thus separating contacts 55, 56 which causes deenergization of coil 41 and closing of valve 36, the latter also serving as a dump valve for gas in the motor, and the piston returning to its original position under influence of spring 31. If switch 54 is still closed on engagement of breaker contacts 3. 4, a circuit from supply 58, through switch 54 and coil 73 of switch 57 ensures energization of coil 73 and thus the separation of contacts 55, 56 until switch 54 is opened. Further, there is another holding circuit for contacts 55, 56 from supply 58, contacts 51 52, resistor 105, and coil 73. As coil 41 of valve 36 is in series with contacts 55, 56 it cannot be again energized while these are locked open. The breaker is tripped either automatically by means of a fault relay 16 or by a switch 85 completing a circuit which energizes trip coil 14 which causes latch 13 to release linkage 2, the circuit being from supply 58, coil 14, and contacts .76, 77 of switch 75 which are closed when the breaker is closed.

Title: Improvements in or relating to fountain pens
IPC: B43K5/06
Filed: 1937-03-18
Abstract: 473,481. Fountain pens. CONWAY, STEWART, & CO., Ltd., and JONES, A. S. March 18, 1937, No. 8118/36. [Class 146 (iii)] In a self-filling fountain pen having a screw-actuated plunger operated by a rotatable element at the rear end of the pen, continued rotation of the element after the plunger has reached the fully-retracted position causes a small-pitch screwthread near the plunger to engage in a corresponding screw-thread in the barrel. The plunger 2 is actuated by means of a number of elements 3-5 screwing into one another, the plunger being attached to the rod-like element 5 which is formed with four deep-pitch screw-threads so that the rod is of substantially square or crosssection. The tubular element 4 is formed with a square internal flange to engage the rod 5 and with four external screw-threads adapted to engage in a squared internal flange on the element 3. Separation of the parts is prevented by flaring the ends of the elements 4, 5. The element 3 is rotatably mounted between a shoulder 9 and a ring 10 in a bush 8, screwed into the end of the barrel, and is provided with an operating-head 11. The friction between the plunger and barrel is normally sufficient to prevent rotation of the plunger, but when the parts 3-5 are completely screwed home, the plunger, on continued rotation of the head, is caused to rotate to cause a screw-thread 14 thereon to engage with a corresponding screwthread in the bush 8 and seal the barrel against leakage,

Filed: 1953-03-24
Abstract: 740,767. Manually-actuated reciprocating pumps. CHAMBERLAIN INDUSTRIES, Ltd. March 24, 1954 [March 24, 1953], No. 8137/53. Class 102(1). In a manually-actuated reciprocating pump, having high and low pressure spring-loaded pistons 1, 2, Fig. 2, for transmitting hydraulic pressure to e.g., the plunger B, Fig. 1, of a tube bending machine, a cylindrical pin 13, slidable in the bore of a lever attachment 7 pivotally mounted on the pump casing is movable to engage either one or both the pistons. The arrangement being that initially the pin engages both pistons so that they both plunp liquid from the reservoir D into the plunger barrel A until the resistance to pumping becomes too great whence the pin is slid in the bore until only the high pressure piston is engaged thereby and this piston only is operated. If desired the low pressure piston may be operated alone. A circlip 14a disposed around each piston limits its upward movement when idling. Dimples 15 in the pin 13 engage a spring-pressed ball 14 to hold the pin in each of its operative positions. In a modification, the pin 13 is replaced by a pair of arms pivoted on the attachment 7. Each arm being capable of independently swinging into or out of engagement with its associated piston. Specification 597,228 is referred to.

Title: Improvements in appliances for playing card and like games
IPC: A63F1/02
Filed: 1919-04-01
Abstract: 145,876. Foster, R. F. April 1, 1919. No Patent granted (Sealing fee not paid). Card games; games of chance.-Appliances for playing games resembling auction bridge comprise a pack of fifty-two cards divided into four suits of thirteen cards each, a fortuitous score-determining device, Fig. 7, with a spinning pointer 9, and a selection chart, Fig. 6, for ascertaining which of the dials on the score-determining device is to be used. The suits, Fig. 1, may be identified as cotton, industrials, railroads or wheat suggesting transactions on the stock exchange. The value of a card within its suit is indicated by a marking 3, and in addition, a scoring value 4 which also guides the player when bidding is marked on the card. In playing one form of game, the cards are dealt as in ordinary auction bridge, and the players bid until the final bid is reached, expressed for example in hundreds. The cards need not now be played, but instead, the scoring value of the bidder's and his partner's hands is counted by means of the indications 4. By looking under this scoring value in the row 25, Fig. 6, and opposite the final bid value 15, a number is ascertained corresponding to one of the numbered dials shown in Fig. 7. The pointer 9 is placed upon the selected dial and is spun, the are wherein the pointer comes to rest indicating the value of the score for that particular deal. If the numeral selected from the chart is on the right-hand side of an irregular line 18, Fig. 6, the score counts to the bidders, otherwise the score counts to the opponents. An ordinary pack of cards with the conventional markings may be used with the addition of numerical value-markings which afford a guide to the bidding value of the hand. When ordinary cards are used, their bidding and counting values are given on a set of tables.
