Abstract: 407,093. Stays. NICHOLLS, J. H., The Poplars, Nottingham Road, Spondon, near Derby. Sept. 17, 1932, No. 25864. [Class 65 (i).] A window stay comprises a bar, with a longitudinal slot, connected to the window and a pin on the frame provided with a lateral extension parallel to the plane of the window frame so that the slot in the bar can only be passed over it when the window is closed and the bar placed parallel thereto ; the slot limits movement of the window from the closed position unless the bar is first disengaged from the pin. The pin may have an extension above the lateral extension, to engage holes in the bar to hold the window open, and means may be provided to prevent motion of the window when opened to the full extent of the slot. In the form shown, the stay-bar A, connected to the window by a universal joint, has a slot C and holes J, and the pin D has two lateral extensions F, below the top, to prevent disengagement from the slot except when the window is closed. The window is locked in the closed position by engagement of one of the holes J with a pin K as well as the slot engaging pin D. For holding the window open, the holes J engage with the upper part of pin D, the bar resting on the projections F. When the window is open to the limit of the slot C, a stud G on the underside of the bar A engages a slot H in the baseplate of the pin D to prevent movement of the window. The bar is preferably cranked, as shown, so that the slotted part is lower than the remainder. In a modification, the pin D does not project above the extensions F, a separate fixed pin being provided to engage the holes J in the bar when the window is open. According to the Provisional Specification, the slot C may be formed in a lug projecting from one side of the bar in order to avoid weakening thereof. With this construction the screws fixing the pin D to the frame may be covered to prevent their removal from outside when the window is partly open.

Abstract: 373,510. Hydraulic shock-absorbers- STEVENS, A. H., 5, Quality Court, Chancery Lane, London.-(Delco Products Corporation ; 329, East 1st Street, Dayton, Ohio, U.S.A.) Sept. 15, 1931, No. 25875. [Class 108 (iii).] In apparatus in which a double-ended piston 31, 32 is reciprocated by a lever 45, the compression chambers 50, 51, corresponding respectively to spring compression and spring rebound, are each provided with a pressure release valve to permit the flow of fluid into the opposite chamber, the spring compression valve providing a fixed orifice for small movements and an additional opening for larger movements, while the rebound valve provides successively different openings according to the rate of movement.. During spring compression, liquid flows from the chamber 51 through the passage 53 to the valve chamber 64, which communicates by the opening 71 with a passage 52 leading to the other compression chamber 50. For small movements, liquid flows through a groove. 70 in the fixed stem 67 while for larger movements, the valve 68, which slides on the stem 67, is forced off its seat against the resistance of the spring 69. The rebound valve 58 is forced on to its seat by a light spring, 61. For small rebound movements liquid flows from the passage 52 through the gap between the stem 60 of the valve and the passage ; while for larger movements the stem moves out of the passage 52 and the valve then abuts against the stronger spring 62, thus providing a larger opening but with increased resistance to further movement. The compression chambers are replenished with liquid from the central reservoir 25 through passages in the piston leading to one-way valves 37, 40. Wear pieces 43, 44 are held up to the operating lever 45 by springs 47.

Abstract: 505,534. Shaping glass tubes. JACKSON, L. MELLERSH-. (Kimble Glass Co.) Sept. 6, 1938, No. 26054. [Class 56] A machine for bottoming glass tubes of elliptical crosa-section comprises chucks for holding both ends of a tubular glass blank and rotating it while the middle portion is heated, means for moving the chucks apart to separate the blank into two tubes with closed ends, and means for moving the chucks together again to bring the closed ends of the tubes into a centrally-disposed mould. The glass blanks 36, Fig. 3, are fed one at a time from a hopper by notched discs 34 and are deposited on a conveyer 29. This consists of a pair of chains 41 provided with a number of carriages 42 in which are journalled discs 46 that receive the blanks 36. The blanks are carried over burners 54 which preheat the middle portions of the blanks, and during the movement, the discs 46 are rotated by chains 48 and so rotate the blanks. After the preheating, the blanks are picked up by a transfer device 32 composed of notched bars 58 which move in a rectangular path and deposit the blanks between chucks 61. The notches 59 in the bars 58 are of sufficient width to allow the blanks to settle with their major axes horizontal. The chucks grip the ends of the blanks and rotate them while the middle portions are further heated by burners 92, Fig. 11. The chucks are then separated to pull out the softened part of the blanks and the flame from the burner cuts through the glass to form each blank into two tubes with closed ends. Other burners 93 then round the ends. Next, the tubes are further separated by the chucks, and a mould 89 is raised to a position where moulding-cavities 91 are in line with the axes of the chucks. The rotation of the tubes is stopped, and the chucks are moved inwards towards the mould. Compressed air is then admitted through the chucks to shape the tube ends in the moulds. The chucks are again separated and release the tubes on to the transfer device 32 which deposits them on a conveyer 31, Fig. 3. The tubes are again rotated and are.carried through housings 137 containing burners that smooth the open ends of the tubes. Finally, the finished tubes are deposited on a shoot 139.

Abstract: 407,405. Circuits for magnetic instruments. STANDARD TELEPHONES & CABLES, Ltd., SANDEMAN, E. K., ATHERTON, J. F., and HARDISTY, R. W., Connaught House, Aldwych, London. Sept. 22, 1932, No. 26367. [Class 40 (iv).] A loud-speaker, moving-coil microphone, gramophone recorder or reproducer or the like having two or more inductive windings is given a substantially constant impedance over the voice-frequency range by associating therewith resistance and capacity to form a constant impedance lattice network. The resistance and capacity may be associated with a transformer connected to the loud-speaker &c. In the form shown in Fig. 1, the windings W1, W2 are associated with equal condensers C1, C2 to form a network which is terminated by a resistance R, the values being determined by R = #L/2C where L is the total inductance and C the capacity of each condenser. The inductance may be taken as that corresponding to the knee B in the reactance-angular frequency curve, shown in Fig. 3, of the inductive windings, R being made equal to the impedance of the circuit which works into the loud-speaker &c., or the most suitable corresponding values of R and C may be determined experimentally. The network may be formed by associating the resistance R and condensers C1, C2 with a split-primary transformer as shown in Fig. 2 particularly when the loud-speaker &c. has a single winding. The invention is useful for coupling loud-speakers to pentodes, or where a number of moving iron instruments are connected in parallel so that normally the total impedance at low frequences would be extremely small.
