Abstract: 1,197,766. Casting building structures. J. L. FONTAINE. 18 Dec., 1967 [20 Dec., 1966; 21 July, 1967], No. 57484/67. Heading BSA. [Also in Divisions E1-E2] A building structure is made by laying the centre of a mesh net with deformable meshes over a supporting structure including balloons 21-26 or other curved supporting members and, if required, rods 32, 33 to define projecting upper portions of the structure, and stretching the lower edges of the net downwardly or outwardly, and then either projecting a layer of plaster or plastics material directly on to the net to form the structure, or covering the net with a plastics sheet and another net which is then ooated with a layer of plaster or plastics material. Weights may be hung along the lower edges of the net, or a frame provided on the lower edges to which weights are attached. Hoops and rings are used as supporting members to produce a generally hexagonal domed structure (Fig. 3, not shown), and balloons to produce a rectangular structure with a roof with a four-way pitch (Fig. 1, not shown). Cement or reinforced concrete may be added over the structure produced as above.

Abstract: 1,151,605. Mixing apparatus. STAMICARBON N.V. 22 Dec., 1966 [23 Dec., 1965], No. 57592/66. Heading B1C. A mixer, reactor or dissolving apparatus has a cylindrical vessel 1' with a coaxial openended riser tube 3 in which one or more rotatable shafts 7 carry stirrers 6, 6'; between the riser tube and the vessel walls are one or more helical ribbons 11, 11' of the same hand rotatable about the vessel axis. As shown they are attached to a support 12 rotated by a shaft 13. The riser tube may be hollow for circulation of a heat exchange medium. Preferred proportionate dimensions of the stirrers, helices and vessel are disclosed. Additives may be supplied through pipes 9, 9' discharging immediately upstream of the stirrers.

Title: Electrical regulating system
IPC: G05B19/06
Filed: 1972-12-15
Abstract: 1387940 Automatic control of pressure or temperature M LAKS 15 Dec 1972 [20 Dec 1971] 57968/72 Heading G3R A control system having n restoring means includes a sensor responsive to upper and lower limiting values of a variable to operate second and first relays respectively which when operated cause a motor to drive a sequence switch comprising n cams each associated with a contact set and each having an angularly spaced operating section effective for less than 360/n‹ whereby when the lower limit is exceeded restoring means are sequentially introduced and when the upper limit is exceeded the restoring means are sequentially removed. The means are introduced and removed in the same cyclic order so that the use of the individual means is equalized. In the system described the restoring means are electric motor driven pumps A, B, C, and a pressure sensor 5 has low pressure and high pressure contacts 5a, 5b respectively and these operate contactors 7, 6 respectively. The sequence of introduction of the pumps is controlled by cams 19 driven by motor 8 which is switched on whenever contactors 7, 6 operate. In operation the pumps are switched on in turn by self-holding contacts 9 when the cam followers move into notches 21 in cams 19a, b, c. When pressure is restored, contact 5 centralizes and contactor 6, 7 opens but motor 8 continues to rotate until none of the followers lies in a notch. The pumps remain operative until the other limit is reached when the motor 8 again rotates the cams and the pumps are switched out in sequence as the followers drop into the notches thereby rotating the order in which the pumps are used. Timing devices 10, 11 are used to shut the system down when the pressure cannot be brought within the limits during a period, e.g. for one revolution of the motor 8. It is stated that the restoring means could be heaters or coolers.

Title: Improvements in or relating to anti-lock brake systems
Inventor: SHARP DENIS
IPC: B60L3/10
Filed: 1968-12-13
Abstract: 1,248,788. Anti-lock brake control system. MULLARD Ltd. 13 Dec., 1968, No. 59525/68. Heading F2F. [Also in Divisions G1 and H3] In an anti-lock vehicle brake system having an electrical wheel speed sensor, the braking pressure is relieved when the rotational deceleration of the wheel exceeds a predetermined value and the relieving action is terminated in accordance with a criterion related to wheel rotational movement following the relieving of the braking pressure. The criterion may be any one of the following: (1) when the wheel attains the speed it would have had if it had continued to decelerate at said predetermined value from the speed it had at the instant of operation of the braking pressure relieving means, (2) when the wheel deceleration no longer exceeds said predetermined value, (3) when the wheel deceleration no longer exceeds a further predetermined value following operation of the braking pressure relieving means, (4) when the wheel has ceased to decelerate following operation of the braking pressure relieving means, (5) when the wheel starts to accelerate following the operation of the braking pressure relieving means, and (6) when the wheel exceeds a predetermined acceleration following the operation of the braking pressure relieving means. The control circuit may also delay termination of the relieving until one of the following conditions is also met; (a) the wheel speed is not below a fixed reference speed, (b) the wheel speed is not below a fixed reference speed and also not below the speed the wheel would have had if it had continued to decelerate at said predetermined value from the speed it had at the instant of operation of the braking pressure relieving means, (c) the wheel speed is not below a chosen fraction of the speed the wheel would have had if it had continued to decelerate at said predetermined value from the speed it had at the instant of operation of the braking pressure relieving means, and (d) the wheel speed is not a fixed amount below the speed the wheel would have had if it had continued to decelerate at said predetermined value from the speed it had at the instant of operation of the braking pressure relieving means. To prevent spurious response to momentary decreases of wheel speed produced by whipping in the suspension, the control circuit may require the wheel to decrease its speed by more than a fixed amount at a rate in excess of said predetermined value of wheel deceleration before the braking pressure relieving means is operated. Transistorized signal processing circuits are described in detail (Divisions G1 and H3).

Abstract: 1502258 Sliding-lid boxes METAL BOX Ltd 21 March 1975 [31 Dec 1973] 60276/73 Heading B8P A sliding-lid box of tinplate, sheet aluminium or polyethylene, and which is child-resistant, is deformable by finger pressure to release indentations on the lid and box thereby enabling the lid to be slid open. In one form, Fig. 3, pressure on the lid edges bows the lid so that an indentation 4 is raised clear of an end wall 5. In a modification, there may be an upstanding lug on the end wall engaging an upstanding dimple on the lid. In another embodiment, Fig. 9, the lid has depending sides 8 engaging under the box base, the sides being cut away at 13 so that the box walls can be pressed in to release a dimple 9 in the lid side from a similar dimple in the box side. In a modification (Fig. 8, not shown) the sides 8 are not cut away and the centre of the lid is depressed to cause the sides 8 to deflect outwardly and so release the engaging dimples.
