Title: Apparatus for indicating that a person is attempting to leave his bed
IPC: A61G12/00
Filed: 1972-04-12
Abstract: 1388488 Signalling undesirable movements SANDERS ASSOCIATES INC 12 April 1972 [15 April 1971] 16982/72 Heading A5R [Also in Divisions A4 and H1] A device for indicating that a person is attempting to leave his bed comprises fluid filled detectors 10, 12, 14, Fig. 1, mounted on the side rails 16, 18 and foot board 20 of a bed, the detectors being coupled by tubing 24, 26, 28 to a control unit 30 adapted to give a signal when a predetermined amount of fluid has been displaced from one of the detectors. The control unit 30 may comprise a bellows 48, Fig. 3, connected to the end of each tube 24, 26, 28 via a tube 50, the ends of the bellows acting on limbs of a pivoted trip arm 54. One end of the trip arm carries a lever 62 which is acted upon by a spring 66. Fluid displaced from a detector causes one of the bellows to expand and rotate the trip arm. When the arm has been rotated by a given amount, the amount being determined by the position of an adjustment arm 70, the spring 66 causes the lever 62 and trip arm to flip over in a clockwise direction. The lever 62 electrically connects contacts 76 to provide a signal on the output cable 34. Cable 34 may be plugged into the patient's call-system 38, and the patient call-button which is normally plugged into the system may be plugged into the control unit 30. A reset button 74 is provided to re-cock the trip arm 54. In a modified control unit, Fig. 5B (not shown) provides a series of output signals when a patient attempts to leave his bed. The pivoted trip arm (126) does not act directly on the electrical contacts but releases a latch (110, 108) whereby a serrated member (106) is rendered free to move over the contacts. The contacts (134, 136) are closed repeatedly by the serrations when the mechanism is tripped, the frequency and duration of the signals thus provided being determined by a spring (124) which rotates a lever 104 causing the contacts to be closed and a pneumatic timer (122) which limits the speed of rotation. A transducer comprising a diaphragm (90), Fig. 4A (not shown), which operates on a piston (92) may be used in place of the bellows 48.

Title: Improvements in or relating to hypochlorite compositions for bleaching, sterilising and deodorising
IPC: C01B11/06
Filed: 1930-06-04
Abstract: A soluble hypochlorite is activated for use as a bleaching, sterilizing or deodorizing agent by neutralizing the free alkali thereof without spontaneous decomposition thereof by adding thereto a soluble fluosilicate with or without a soluble fluoride. The free alkali is neutralized slowly and there results an adsorption product comprising colloidal silicon hydroxide and a hypochlorite.  The process may be carried out in solution or by mixing the substances in the dry state.  In an example there is added to a sodium hypochlorite bleach having about 10 per cent available chlorine and excess caustic soda of about 4 per cent a 1 per cent solution of sodium fluosilicate and the mixture is diluted to twice its volume.  If a hard bleach such as calcium hypochlorite is used, sodium fluoride is added to precipitate the calcium and leave a soft bleach.ALSO:A soluble hypochlorite is activated for use as a bleaching, sterilizing or deodorizing agent by neutralizing the free alkali thereof without spontaneous decomposition thereof by adding thereto a soluble fluosilicate with or without a soluble fluoride.

Title: Improvements relating to variable load fluid pressure operated braking apparatus forvehicles, particularly railway vehicles
Inventor: WASHBOURN JACK
IPC: B60T8/18
Filed: 1958-05-30
Abstract: 863,827. Fluid pressure brakes. WESTING- HOUSE BRAKE & SIGNAL CO. Ltd. May 29, 1959 [May 30, 1958], No. 17301/58. Class 103 (1). An automatic control valve device, for variable load fluid pressure braking apparatus, particularly vacuum systems having empty and load brake cylinders, comprises a check valve 11 separating train pipe chamber 14 from a chamber 15 connected to the lower chamber of the load brake cylinder, and a diaphragm 16 separating chamber 19 connected to the upper chamber of the load brake cylinder, and an atmospheric chamber 20. The diaphragm 16 carries a sleeve 24 slidable on a post 25 fixed to a partition 22. A stem 28 is slidable in post 25 and partition 22 and abuts an adjustable bolt 31 of a piston 32 movable against spring 36 to an upper position by the vehicle load (partially acting on the piston) approximating to a predetermined value. The diaphragm 16, stem 28 and valve 11 are biased to the shown positions by springs 26, 33, 12 respectively. Balls 34, interposed between the outwardly flared end of sleeve 24 and stem 28, are biased downwardly by spring 35 on to the post 25. On charging of the braking apparatus, the lower chambers of the load brake cylinder is exhaused to the train pipe via valve 11 as is the upper chamber via the hollow end 29 of stem 28 and valve 11. When vacuum in the upper chamber reaches 6 inches of mercury, diaphragm 16 and sleeve 24 are moved up, the balls 34 wedging between sleeve 24 and stem 28 after the sleeve has moved a predetermined distance, to also raise stem 28. If the vehicle load is below the predetermined value, then when upward movement of diaphragm 16 is halted (by engagement with the valve casing) the end 28 is short of valve 11 so isolating the load brake cylinder from flow of air from the train pipe, the brake cylinder chambers remain connected via the hollow stem end 29. When the load is above the predetermined value, the stem 28 is raised by piston 32 before charging and when diaphragm 16 rises, the stem is moved further to open valve 11 to connect the train pipe to the lower chamber of the load brake cylinder. In a modification, the train pipe is connected to chamber 19 and hollow end 29 is modified to be connected to the upper chamber, a choke and small reservoir, arranged between the train pipe and chamber 19, preventing the device being changed from load to empty condition on emergency brake application when the train pipe is connected to atmosphere.

Abstract: 940,631. Reciprocating motors and pumps. M. TERHO. May 18, 1960 [Oct. 13, 1959], No. 17605/60. Heading F1A. A pump or liquid driven motor comprises a rotatable cylinder block 2, having parallel cylinder bores 4a, 4b slidably mounting spring-loaded pistons 5a, 5b engaging through end balls 7a, 7b, the undulating track 10 of a fixed "crown" member 8. On the admission of pressure liquid e.g., to the cylinder 4a through an inlet passage 20a in a journal block 17 supporting a driven shaft 1 secured to the cylinder block, the piston 5a is urged outwardly and the ball 7a rides down a sloping surface 10a of the track 10 to rotate the cylinder block. At the same time the cylinder 4b is connected to exhaust through a passage 38b in the journal block so that the ball 7b rides up a sloping surface 10b on the track 10 to push the piston 5b inwardly in its cylinder. To prevent damage to the motor parts by ensuring that the pressure liquid entering the cylinder of the outwardly moving piston ceases prior to the piston reaching the end of its stroke and the cylinder of the inwardly moving piston is connected to exhaust prior to that piston commencing its stroke, the summits and radius of the track are made with flat portions. More than two cylinders and piston may be used, there being corresponding adjustment of the track 10.
