Abstract: 839,261. Respiratory apparatus. NORMALAIR Ltd. July 1, 1958 [Aug. 23, 1957], No. 26648/57. Class 81 (2). In a device for indicating faults in a respiratory apparatus comprising a demand regulator, means for driving an electrical impulse at each inhalation and a time delay means which actuates a warning circuit if the interval between pulses exceeds a predetermined limit, an oxygen by-pass 17 is operable by closing the warning circuit and is provided between the inlet 18 and outlet 19 of the demand regulator 20. When contacts 9, 10 of the warning circuit are closed to energize the warning light 14, a circuit through a solenoid 15 is simultaneously completed. Energization of the solenoid opens a valve 16 in the oxygen by-pass 17. A restrictor 21 reduces the pressure of oxygen passing through the by-pass. In the event of the warning system being operated by a constant flow of oxygen through the regulator, the by-pass may be closed by pressing a pushbutton 22 which breaks the circuit through the solenoid. The push-button is held depressed, as long as the warning circuit is operative, by an electromagnet 24 in parallel with the warning light. A relief valve 23 is in the demand regulator outlet 19. Specification 801,773 is referred to.

Title: Improvements in or relating to a towelling dispensing cabinet
IPC: A47K10/28
Filed: 1945-10-12
Abstract: 602,046. Dispensers for towelling. STEVENS, A. H. (Steiner Sales Co.). Oct. 12, 1945, No. 26672. [Class 18] To prevent uneven wear of the granular surface of a towelling dispensing and measuring roll by sudden stoppage of delivery; its permissive movement, by a pull on the towelling, is such that a relatively large member of portions of the surface are successively stopped beneath a superposed pinch roll before a given portion again occupies that position. The invention is shown applied to a towelling dispensing device wherein towelling from a supply passes between a measuring roll 20 and a freely supported pinch roll 36 and thence to a take-up drive roll 21 which makes frictional contact with a solid towelling roll 84. Between rolls 20, 21, the towelling hangs from the cabinet in the form of a loop and a pull thereon causes the measuring roll to rotate for dispensing purposes. A chain and sprocket drive 40, 41, 46, connects the measuring roll and take-up drive roll, the ratio of the sprocket teeth being either greater or less than unity. To effect a take-up corresponding to the amount supplied, the diameters of the rolls 20, 21 are in the same relationship as the ratio of the sprocket teeth. This arrangement permits the measuring roll to complete' either a part revolution or more than a revolution for each revolution of the takeup roll. The take-up and measuring rolls are mounted in bearings 18 in plate 12, secured to upright plates 6. The take-up drive roll has a stop 32 to engage a member 60 that is slidable on a plate 50 and is actuated by a slotted link 67 eccentrically connected to the roll 21. On rotation of the roll 21 the stop member 60 is raised by the link 67 and held in that position by cooperating suction cups 80, 79, so that it engages the stop 32. A valve hole 80<1> allows the cups to become separated after a predetermined interval of time to permit further withdrawal of towelling.

Title: Improved method of and apparatus for the conveying of powdered or pulverulent dry material in bulk
Inventor: ALLEN ROBERT WILLIAM
IPC: B01J8/40
Filed: 1959-08-05
Abstract: 887,309. Pneumatic conveyers. SIMON Ltd., HENRY. Aug. 4, 1960 [Aug. 5, 1959], No. 26680/59. Class 78 (1). Apparatus for the fluidization of dry pulverulent material to facilitate its conveyance comprises an inclined porous material i and means for producing cyclic changes of air pressure to enable the material i to move and mechanically agitate the pulverulent material as it is fluidized by the compressed air. As shown in Fig. 4, a compressor b feeds a reservoir a via an adjustable reducing valve d. When the air in the reservoir a is at a predetermined pressure, it lifts a valve m and is thus permitted to act upon a piston x which thereby displaces a cam 11 so as to open a valve 12. The latter permits highpressure air to pass to act on a piston n and this opens a valve f to allow air from the reservoir a to pass to a rotary distributer u. The latter passes the air to one of a series of chambers h each having a respective porous diaphragm i. The effect of the air being released from the reservoir a to the chamber h causes a drop in pressure and a consequent closing of the valve m. The piston x is returned by its spring 13 and consequently the valve 12 is closed. Pressure is no longer supplied to piston n and the valve f is closed by its return spring. Pressure now commences to build up again in the reservoir a until it is sufficient to open valve n and the cycle recommences. Each time the piston x is deflected, a pawl y engages a projection on the distributer u so as to connect the air supply with successive chambers h. Instead of the connecting pipe from the distributer to the chamber h being as shown, it may be arranged as in Fig. 2 in which further air is drawn in through a tunnel q by Venturi action. The whole of the porous material i may be flexible. Alternatively it may be rigid, and it may be resiliently mounted around its periphery so as to permit its deflection (Fig. 3, not shown). In a simpler modification (Fig. 1, not shown) the outlet from the valve m is connected directly to the chamber of the piston n.

Patent GB-886229-A (GB)
Title: A typewriting machine with electric carriage return and line spacing mechanism
IPC: B41J11/24
Filed: 1958-08-20
Abstract: 886,229. Typewriters &c. OLYMPIA WERKE A.G. Aug. 20, 1958 [Oct. 28, 1957], No. 26794/58. Class 100(4) An electric typewriter having a mechanism which can effect line spacing with or without electric carriage return at any position of the carriage has a line spacing lever 8 acting on a ratchet 11 and connected by a drawband transmission 4, actuated by a clutch 1, to a shaft 3 of a constantly running motor. To cause line spacing only a key Z is depressed which acts through a rod 19 and control lever 20 to pivot a lever 23 which in turn pivots a lever 6 so that it enters and locks a wheel 14. Movement of the lever 20 also withdraws a latch 34 from a lever 33 so that a spring 29 can cause a rod 28 to raise a member 31 to hold the lever 6 in engagement with the wheel 14 even if the key Z is immediately released. The key Z has also closed a switch Zl and when the movement of the rod 28 closes an auxilary switch 32a a relay operates the clutch 1 so that the drawband 4 effects a line spacing movement and at the same time increases the force on the wheel 14 so that it pivots the lever 6 against springs 26, 29 to again open the switch 32a and release the relay. If the key Z has been released a spring 52 will restore the levers 20, 23 and also re-lock the lever 33 but if the key is still depressed the lever 23 held in its operative position and will cause the lever 6 to restore to its locking position as the drawband 4 slackens. The spring 29 will again actuate the rod 28, as the latch 34 has been held inoperative, and close the switch 32a which through a delay circuit, which allows time for the line spacing lever 8 to restore, again actuates the relay to cause repeated line spacing while the key Z remains depressed. To effect carriage return with line spacing a key W is depressed which closes switches W1 and W2 in addition to Z1 to operate the relay but does not actuate the tie bar 19 so that the escapement wheel 14 is not locked and both carriage return and line spacing are effected by the drawband 4 when the clutch 1 operates. A locking circuit locks the keyboard during carriage return and by opening a margin stop switch during line spacing. Carriage return can be interrupted during tabulating and other actions by opening contacts in the relay circuit.

Title: Improvements in or relating to a device for holding sheep and the like animals
IPC: A61D3/00
Filed: 1960-08-02
Abstract: 940,392. Animal holding appliances. N. R. WOODS, and W. H. CLARK. Aug. 2, 1960, No. 26805/60. Heading A5R. An animal holding device comprises a frame with a horizontal pivot on which an animal holder is pivotal at or near its upper edge on one side of the frame and a cradle parallel to the holder on the other side of the frame for the reception of an animal which is inverted or turned on its side as the holder is pivoted. The frame consists of two base supports 1, 2 one of which supports vertical members 3a, 3b, at the entrance of the holder, the other supporting a frame 4 closing the other end of the holder. Stub axles 8 disposed on one vertical member and on one side of the frame 4 rotatably support a tube 13 which carries the holder. The holder comprises tubular members 14 fixed to the rotatable tube and forming one side 11 and a support for a floor 12, the other side 10 of the holder, which carries a counterweight 23, being pivotal on a bar interconnecting the floor-supporting portions of the members 14. A handle 20 is fixed to the pivotal side 10. A chain 26 extends between the rotatable tube 13 and the pivotal side to limit movement of the holder sides away from each other. The cradle 28 is supported by cylindrical sleeves 29 on the rotatable tube which is rotatable independently of the connections. The cradle is supported by an adjustable brace 35 and comprises a downwardly extending curved portion, comprising curved members 31 and slats 33, which is hinged at its lower edge to a similarly constructed upwardly extending curved portion. The upper edges of the cradle portions are interconnected by an adjustable chain 39 which supports the neck of an animal in the cradle and thus tends to cause the portions of the cradle to approach one another. In use, the animal is driven into the holder, the handle 20 is pivoted towards the opposite side of the holder so that first the sheep is gripped between the sides and then the holder is rotated on the stub axles to invert and raise the animal to such a position that it may easily be transferred to the cradle. Chains 27 interconnecting one side of the holder and one base support prevent access beneath the holder when it is in raised position. In an alternative construction one end of the cradle is connected to the frame only by a ball joint (not shown) the other end being supported on a bar extending from the frame, the cradle thus being pivotal in a horizontal and a vertical plane so that it may be arranged at right angles to the holder or inclined towards or in contact with the ground.

In a system for indicating an abnormal tem. perature difference between two parts of a machine, e.g. bearings, thermistors B associated with the respective parts form adjacent arms of a Wheatstone bridge, the other arms being formed by a potential divider C, D, C. A moving coil indicator H in the bridge diagonal has its sensitivity adjustable by a rheostat G and if it reaches either end of its scale closes contact l<SP>2</SP> or l<SP>3</SP> to operate a corresponding relay J or K which locks up, energizes a common audible alarm L and lights a warning lamp O. P individual to the hot bearing &c. Contact E on the potential divider enables the bridge to be balanced for a normal condition in which the temperatures of the two parts are not the same. To guard against the case in which both bearings become overheated together, a differential relay R carries the thermistor current in one winding, the other being supplied by a rheostat which determines the temperature of the bearings at which the relay will operate. When relay R pulls up, it energizes S which locks and operates the common alarm and the warning lamps of .both bearings. A modification is referred to but not described in which each bearing has indicators for safe, excessive and dangerous temperatures respectively.
