Abstract: 1383664 Freight containers MARTIN FIALAKG 3 May 1972 [3 May 1971] 20526/72 Heading B8P [Also in Division E2] To strengthen the doors of a container against torsion, diagonal bars 9, 10 are provided, and are interconnected by a plate 19, and the hinge eonstructuon is such that if a load is applied at the top left hand corner (Fig. 5) along the longitudinal axis of the top door frame beam 5 a tensile load will be taken by the diagonals 10 and no load will be taken by the diagonal 9. The diagonals are connected to the plate 19 by members 21 or by pins engaging holes or by notched engaging members (Figs. 6-11). The hinge pins 50 engage hinge eyes 49 which are slotted at one side or have an oval hole therein to allow relative movement between the door and its frame in one direction but not in the opposite direction.

Title: Improvements in or relating to rotary valves for internal combustion engines
IPC: F01L7/06
Filed: 1945-08-10
Abstract: 600,852. Rotary valves. PEACEY, R. S. Aug. 10, 1945, No. 20568. [Classes 7 (ii) and 7 (vi)] A rotary disc valve 7 having a single port co-operating with inlet and exhaust ports is situated in a recess 6 in the valve-head 2, and the face 15 of a valve cover 13 forming the combustion chamber 14 masks the port 12 during the power stroke so that the flame cannot reach the valve seat 4. The combustion chamber 14 having a centrally placed spark-plug 16 is part-hemispherical and has crescentshaped openings adjacent the valve 7 and cylinder port 5. A driving disc 18, keyed to the valve shaft 8 to allow slight axial movement thereof, engages a toothed driving member 19 mounted on ball-bearings supported on a sleeve 20 projecting from the cylinder head and carrying a sprocket-wheel 21 driven from the crank-shaft. A spring 24 engaging a washer 25 on the valve-stem presses the valve upon its seat, and the edge of the valve disc may be grooved or formed with a shallow thread to return excess oil delivered through a groove 26 on the stem.

Title: Improvements in and connected with piano players
IPC: G10F3/00
Filed: 1927-08-05
Abstract: 301,773. Wood, E. H. A., Brown, F. W., and Cooklin, I. Aug. 5, 1927. Piano - players ; pneumatic actions ; tracker-bars ; expressioncontrolling ; winding-mechanism. -In a piano-player operated by compressed air, diaphragm-controlled regulating slide-valves between the reservoir and the wind-chest are also operated by lift-valve devices from solo-holes in the tracker-bar, for accenting. The slide-valves are further under manual control. Similar liftvalve devices operate diaphragmmounted pads striking the pianokeys. A slide-valve 12 (treble or bass) between the reservoir 8, fed by an electrically driven aircompressor 7, and the wind-trunk 4, is mounted on a stem 48 attached to two unequal diaphragms 10, 11 the diaphragm 11 being in direct communication with the windtrunk 4 by a tube 24. Diaphragm 10 communicates with a chamber 31 in a valve device 6, similar to that shown at 2, Fig. 3. On uncovering a solo hole 20 pressure in a chamber 25 connected thereto is released, so that pressure from the wind-trunk 4 may raise a valve 29 and diaphragm 26 (and also a valve 29x, closing exhaust holes 34) and so reach the diaphragm 10, thus opening the valve 12 wider. The valves 12 may also be opened wider by a hand-lever 49 pivoted on a pin 50 and having a projection 52 which acts under an inclined arc 53 on a crosshead 54 carried by the stems 48 through the intermediary of springs 55. The valve devices 2, on the venting at 36 of a notehole in the tracker-bar 1, admit air to elongated diaphragms 42 carrying pads 43 directly operating on the keys 44, 45. The tune-sheet motor, operated by air from the reservoir 8, drives the primary gear shaft by a chain, the shaft being moved longitudinally by a hand-operated spindle having a crank pin working in the groove of a pulley, to put the winding or re-winding gear in operation. A spring brakes the delivery spindle. The speed of the tune-sheet motor can be varied by varying the speed at which the air pump is driven, or by means of a hand-valve between the reservoir and the motor, or by a discharge valve on the reservoir. The backcentre 77<x>, Fig. 9, for the music roll may be adjustable by a screw 102 pressing the end 101 through a bell-crank 104 against the action ot a spring 100. The casing of the player is fixed against the end cheeks of the keyboard by screws, and is adjusted vertically over the keys by other screws with rubber feet.

Abstract: 343,416. Electro-optical light-valves. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Kell, R. D. ; Sanders Avenue, Schenectady, New York, U.S.A.) July 8, 1930, No. 20681. Convention date, July 8, 1929. [Class 40 (iii).] If the bias voltage of a Kerr cell, such as described in Specification 235,857, [Class 40 (iii), Telegraphs, Electric], be plotted against the percentage of light passed by the cell, the volt-light characteristic illustrated in Fig. 2 is obtained. The bias voltage normally applied is represented at A ; the invention consists in using the cell on one of its higher characteristics, e.g. applying a bias voltage represented at D where a given change in the voltage applied to the cell produces a larger variation in the light passed by the cell. The television receiver, Fig. 1, has a Kerr cell 14 to the plates of which are applied signals from a radio receiver 20 through a valve 21 and a biasing battery 22, a resistance 23 being connected in shunt with the cell 14 and battery 22. Where the distance between the plates of the Kerr cell is 0À02 inches and its length is 1À2 inches, a bias voltage of 2600 volts is applied, where previously a bias voltage not exceeding 1200 volts has been used. A rotating lens disc 16 projects the light passing through the cell on to the screen 10.
