Title: Improvement in Self-locking Door-locks.
Inventor: LINDBERG JOHAN WALDEMAR
IPC: E05B63/20
Filed: 1917-03-17
Abstract: 104,886. Lindberg, J. W. March 10, 1916, [Convention date]. Night-latches.-Relates to a latch-lock of the kind in which the bolt is held in an intermediate position when the door is open, the bolt being forced back by the contact of its bevelled end with the striking-plate and ultimately springing out to the fully shot position. The bolt 1 is shown in the intermediate position in Fig. 3, being held by the engagement of the horn 11 on the operating-member 9 with the hook 5 on the tail of the bolt or on the shoulder 4 of the plate 2 connected therewith. When the door is slammed, the bolt 1 is thrust back, and the member 9, being disengaged, is thrown forward by its spring, the bolt then shooting forward and being locked by the lever 6 falling behind the projection 3<1> on the plate 2. In unlocking, the horn 10 of the member 9 lifts the lever 6, and the horn 11 draws back the bolt. As the bolt returns from the withdrawn to the intermediate position, the horn 11 slides upwards against the face of the shoulder 4 till it catches under the hook 5. When the door is open, the bolt can be pressed back by hand so far that the lever 6 engages over the projection 3<1>, holding the bolt out of action. From this position, the bolt is released by turning the handle in the reverse direction to that used for opening, the horn 10 of the member 9 then acting on the rear surface of the projection 8. The lock is operated by a key through the pivoted arm 13, which may be controlled by levers 15. The guard 16 prevents operation by a wire inserted in the keyhole.

Abstract: 1,173,256. Fluid pressure brakes. BENDIX CORP. 25 Jan., 1968 [2 Feb., 1967], No. 4023/68. Heading F2F. In a fluid pressure servomotor of the vacuumsuspended type for braking systems a housing, consisting of a front shell 10 and a rear shell 12 joined together by a twist lock connection 14, houses at least one plastics pressure differential responsive movable wall 22 reciprocally mounted within the housing and a valve device located within a tubular portion 28 of the movable wall 22 projects outwardly through an opening in the housing, the valve device being operatively connected to an operator-actuated push rod 113 adapted to communicate the interior of the tubular portion to the control chamber side of the movable wall upon actuation of the push rod, the servomotor having means for preventing the interior of the tubular portion from communicating to atmosphere and establishing communication to a source of superatmospheric pressure air via connection 120 an a hollow portion 108 of the push rod. In operation, when the brake pedal is depressed a reaction plunger 72 moves inwardly under the action of the three-part push rod assembly 108, 110 and 113 to close the gap between a head 74 of the plunger and a deformable disc 30. At the same time a valve flange 76 on the movable wall 22 closes off vacuum suspension of the chambers on either side of the wall 22 and a diaphragm 18. Further inward motion of the brake pedal causes further inward motion of the reaction plunger 72 to remove the valve seat, formed on the rear face of reaction plunger 72, from the valve face 86 of the poppet valve to communicate the chamber to the radial passage 166 through the tubular portion 28 to allow super-atmospheric air from a reservoir 122 to create an immediate pressure differential across the wall 22 and the diaphragm 18 to project the force transmitting rod 36 forwardly and pressurize a master cylinder 40 to apply the vehicle brakes 46. Fig. 3 shows an alternative embodiment wherein a cup-shaped structure 152 is secured to the servomotor housing 12b and is connected via a fitting 154 to the source of super-atmospheric pressure air. In this case the push rod 158 is not formed with a hollow connection and a standard valve arrangement 72b is utilized. The push rod 158 is located in the end of the cup-shaped housing 152 through a sealing plate 160 which is arranged to be held between a plate 162 and an inwardly-turned flange 164 of the housing 152 to permit radial movement of the sealing plate 160 to accommodate arcuate action of the push rod 158.

Abstract: 809,853. Electrophonic musical instruments. HOHNER A.G., M. Feb. 16, 1955 [Feb. 16, 1954], No. 4588/55. Class 88 (2). In a key-operated musical instrument using vibrating reeds as component electrodes of variable capacitors to generate electrical oscillations rich in harmonics, a reed is mounted to vibrate in a slot in a carrier constituting the other electrode of the capacitor. One of the electrodes is divided into sub-electrodes to form the electrodes of a number of capacitors with a common electrode. In one embodiment, Figs. 15, 17, a reed 90 is mounted on stacked and insulated metal carrier plates 91, 92, 93 by an insulated peg or rivet 89. Different biasing potentials may be applied to the three carrier plates. As shown in Fig. 17, the slots in the metal plates may have different widths but insulating material may be added to provide a smooth passage for the air flow. In Fig. 18 the carrier plate 131 is divided into two parts by insulation 132 and is formed with slots for a number of reeds with a common lead 139. In Fig. 3 the stationary electrode 32 is formed in one piece. In another embodiment, Fig. 19, separate insulated plates 104 to 108 are formed on the carrier alongside the reed 100 as shown. Excitation of reeds.-The reeds may be driven by an air supply. When a number of reeds are mounted on a common carrier, as in Fig. 3, it is not necessary to supply air to all the reeds. The reeds not driven by air vibrate in sympathy with the driven reeds. A reed 50, Fig. 7, may be mounted on the end of a key 54, pivoted at 52, so that the reed vibrates when the key strikes the stop. A reed 56, Fig. 8, is vibrated by a downwardly directed air stream when the key 61 is depressed to move the damper 60 out of contact with the reed. Acoustic reaction.-A reed 37, Fig. 4, is mounted on a rubber sleeve 38 to avoid acoustic reaction from the loud-speaker of the instrument. For the same purpose, the reed may have an oscillatory mechanical impedance twenty times its radiation impedance. Insulation.-The metal carrier 40, Fig. 4, may be coated with a non-conducting layer 41 of aluminium oxide deposited electrolytically. Circuit arrangements.-The reed capacitor 63, Fig. 9, is biased by a battery 69 and a resistor 67 and is connected to the grid of an amplifying valve 73 through a capacitor 71. In another circuit, Fig. 11, a reed capacitor 77 may be used to frequency-modulate the output of an H.F. oscillator 78 which is coupled to a tuned detector circuit 85. The output on lead 86 follows the vibrations of reed capacitor 77. In another circuit, Fig. 13, a reed capacitor 87 is included in one arm of a bridge. An H.F. alternating current is applied across one diagonal. The other diagonal includes a demodulator and amplifier circuit 88 which provides the output.
