Title: Improvements in or relating to detergent briquettes
Inventor: BATH DAVID FRANK
IPC: C11D17/00
Filed: 1963-12-11
Abstract: Detergent briquettes consist of three layers, the first and third layers being outer layers each comprising a compressed material which itself comprises one or more functional ingredients of the detergent briquette and which, on compression, produces a relatively smooth, abrasion resistant surface, and the second layer being an inner layer comprising a built detergent composition which is a mixture of one or more particulate inorganic builder salts and a particulate detergent composition, and which would produce, if compressed alone, a rougher and more easily abraided surface than that produced by either of the outer layers, the mixture being produced in the absence of liquid or in the presence of insufficient liquid to destroy the particulate nature of the mixture, the second layer constituting at least 50%, by weight, of the briquette.  The briquettes are produced by superposing the three layers in the die-box of a briquetting press, and then compressing the layers together.  The layers may be of different colours, and the first and third layers may be of the same functional composition.  The ingredients of each layer are chosen merely to satisfy the above requirements, provided that the whole briquette is of suitable composition. In examples, the inner layer is composed of two or more of the following:-sodium tripolyphosphate, sodium silicate, sodium perborate, soap, sodium dodecyl benzene sulphonate, sodium tallow alkyl sulphate, lauric acid monoethanolamide, coconut fatty acid amide, sodium carboxy methyl cellulose, tetra sodium salt of EDTA, and water, but may also contain alkali metal pyrophosphates, orthophosphates, and carbonates, sodium sulphate, and aqueous sodium silicate or starch as binding agent instead of water; whilst the outer layers comprise one or more of the following:-sodium tripolyphosphate, trisodium phosphate, sodium sulphate, sodium silicate, sodium perborate, soap, sodium toluene sulphonate, sodium dodecyl benzene sulphonate, coconut and lauric fatty acid monoethanolamides, cetyl alcohol, and water, but may also contain fatty acids and amides.  Preferably the inner layer is 85-95% of the whole briquette.

Abstract: 1344868 Controlling inverters LICENTIA PATENT-VERWALTUNGS GmbH 22 Oct 1971 [29 Oct 1970] 49219/71 Addition to 1344867 Heading H2F In an inverter 15 having a commutating capacitor 12 alternately charged from sources 13, 14 to opposite polarity, via thyristors 4, 5, a control system comprises delay circuits 20, 21 arranged to limit the minimum interval between the firing of one thyristor 4 and the next thyristor 5 so as to permit adequate charging of the commutating capacitor 12. As described, the main thyristors 2, 2<SP>11</SP> forming part of the main inverter 15 are turned off by triggering thyristors 3, 311 so as to discharge capacitor 12, previously charged from sources 13 or 14, through the main thyristors 2, 2<SP>11</SP>. The voltage on the commutating capacitor 12 is compared at 26 with a reference voltage U cmin, rectifier 27 making the circuit insensitive to polarity, a Schmitt trigger 28 being operated if the voltage of capacitor 12 is above a safe minimum so as to supply a release pulse to the logic circuit 17. Further release pulses + Uc or -Uc are necessary and these are respectively provided by triggering a bi-stable 22 from the triggering pulses for thyristors 4 arid 5 after a delay imposed by monostables 20, 21. The interval between triggering pulses fed to thyristors 4 and 5 is thus maintained within safe limits. Fig. 5 (not shown) depicts a block diagram of the logic circuit 17.

Title: A device for slowing down a freely unwinding cable
IPC: B66D5/14
Filed: 1967-10-31
Abstract: 1,203,803. Winch cable drum brake. GROUPEMENT ATOMIQUE ALSACIENNE ATLANTIQUE. 31 Oct., 1967 [3 Nov., 1966], No. 49323/67. Heading F2E. A winch cable drum is braked by a friction disc brake within the drum operated by a mechanism in dependence upon the amount of unwound cable and centrifugal force on the mechanism, when the drum is freely rotating under the weight of a load. The drum 6 (Figs. 1 and 2) is mounted by bearings 8 on a stationary fixed shaft 10 and is releasably coupled to a drive shaft 11 by a coupling 9. A pair of plate members 26, 28 carrying annular friction members 30 are fixed to the shaft 10 by keys but are slidable axially relative to one another and to the shaft 10. The plates are urged toward one another by a spring 39 to clamp a toothed braking disc 24 which is rotatable on bearings carried by a flange on plate 26. Fixed to the drum is a shaft 12 about which pivots a lever 14 having projections 16, 18. The projection 18 has a catch 19 at its end for engagement with the disc teeth, while projection 16 has a pawl end 17 for engagement with an orifice 20 in the drum. When the cable covers the orifice the pawl is not permitted to protrude therethrough and thus the catch is disengaged from the teeth. With the drive decoupled and the drum rotating freely and accelerating under the weight of a load 4, centrifugal force acts on the lever sufficient to overcome a tension spring 40 so that as soon as the cable unwinds sufficient to uncover oriffice 20 the lever pivots and pawl 17 enters the orifice and catch 19 engages the disc teeth thereby coupling the disc to the drum so that it rotates therewith being slowed down and finally stopped by the friction linings 30 on the clamping plates 26, 28. The amount of free fall is determined by the position of orifice 20 and the length of unwound cable.
