Title: Woodwool slabs
Inventor: HAZLEHURST CHARLES PATRICK
IPC: E04B7/22
Filed: 1966-07-13
Abstract: 1,120,883. Forms of wood. WOODCEMAIR Ltd. 24 May, 1967 [13 July, 1966], No. 31451/66. Heading B5L. A woodwool slab for a roofing or ceiling structure is rectangular in plan view and rebated along its longitudinal edges 11, 12. The slab may be 6 feet long, between 1 and 2 feet wide and 2 inches in depth, and the rebates extend 1 inch from the edges and have a depth of 1 inch. The rebates are formed on the upper side of one edge and the lower side of the other so that when a number of slabs are arranged side-by-side, the rebates interengage and prevent a bituminous sealant when applied over the slabs from penetrating the gaps between the slabs.

Title: Improvements relating to lifting jacks
IPC: B66F1/06
Filed: 1950-12-29
Abstract: 691,337. Ratchet lifting jacks. AUTO SPECIALTIES MANUFACTURING CO. Dec. 29, 1950. [Aug. 16, 1950] No. 31619/50. Class 78 (iii). A jack of the kind having a housing 16 which is raised or lowered on a racthet bar 32 by the alternate engagement and disengagement of a pair of pawls 42, 44, has a C-shaped lifting crutch 18 pivoted to the housing at 64. The crutch shown in Fig. 1 has an upturned lip 68 and an abutment 66 which engage a car bumper 70, and, since the crutch is free to pivot during operation of the jack this two point support is maintained throughout the lift. In a modification (not shown) the abutment 66 is replaced by an outstanding lip at the upper edge of the crutch. As shown in Fig. 5 the crutch may have a projection 114 which engages a hole 104 in a bumper 102, an abutment 112 being provided at the upper edge to further support the bumper. In another modification (not shown) the bumper is supported on a projection similar to 114 and the abutment 112 is dispensed with. In all the embodiments a spring may be provided to urge the lower edge of the crutch upwardly. The jack column 32 which is V-shaped in plan is supported in a hollow rectangular base 12. An operating lever 48 which is pivoted to the housing at 50 carries pawls 42, 44, and a guide roller 78, which co-operates with the apex of the column, is mounted in the lower part of the housing. A spring 46, when in the position shown, allows the pawls to lower the housing on operation of lever 48, but on being urged to the left by anticlockwise rotation of a lever 56 it causes subsequent operation of lever 48 to raise the housing.

Title: An improved alarm
IPC: G08B21/18
Filed: 1953-11-24
Abstract: 743,460. Temperature alarms. CHIPPERFIELD. W. H. June 2, 1954 [Nov. 24, 1953], No. 32533/53. Class 118(1) [Also in Group XIX] An alarm circuit for indicating the condition of an electric switch which responds to the deviation of a predetermined physical quantity, e.g. temperature or pressure, from normal, comprises a first relay coil connected in series with the switch and responding to an alteration in the condition of the switch. due to deviation of the predetermined physical quantity from normaly to complete a circuit through an audible alarm and to switch over a lamp circuit thereby extinguishing a green lamp and lighting a differently coloured lamp, and a second relay coil connected-in series with a re-setting switch, momentary operation of which actuates the second relay, which is self-holding and which opens the circuit of the audible alarm. The second relay remains in its self-held condition and the second lamp remains lit until the fault initiating the response of the switch is corrected and the switch returns to its normal condition. In the circuit shown the switch 10 is normally closed but opens should a variable, such as temperature or pressure, increase above a predetermined limiting value. The relay 12 is consequently de-energized and switch assemblies 19, 20 change over to complete the circuit of the howler 33 and to disconnect the circuit of the green lamp 25 and complete the circuit of the red lamp 34 through a resistor 35. Upon the alarm signal being given an attendant depresses spring-loaded switch 17 which momentarily completes the circuit of the relay 15 thereby changing over switch assemblies 28, 29. The relay 15 is held in its operated position since its circuit is completed through the switches 28 and 19, while the howler 33 is switched off and the resistor 35 is short-circuited by the switch 29 so that the lamp 34 glows more brightly. The circuit remains in this condition until the fault causing switch 10 to open is remedied whereupon the relay 12 is energized again and the circuit returns to its original state. A test switch 13 is provided, operation of which is electrically equivalent to the opening of switch 10. In a modified circuit. Fig. 2 (not shown), an indication is given if the variable being monitored increases or decreases beyond predetermined limits. Two switches, one opening when the variable increases and the other opening when it decreases, are connected in series with the first relay so that the howler sounds and the green lamp is extinguished should either switch open. Also associated with the two switches is a third relay which switches a red lamp or a white lamp in circuit according as to which switch is actuated, so that the red' lamp lights if the variable increases and the white lamp lights if it decreases. It is stated that the circuits may be modified to employ actuating switches which close on the occurrence of abnormal conditions.
