Abstract: 1,273,543. Electric switches. TECALEMIT (DEVELOPMENTS) Ltd. 17 April, 1970 [1 April, 1969], No. 16987/69. Heading H1N. [Also in Division G1] In a liquid level control device, such as for controlling the level of oil in an engine sump 19, a float 8, movable in a chamber 7 and carrying a permanent magnet 9, causes, when the liquid level 35 in the sump 19 and chamber 7 falls, the magnet 9 to close the contacts of an encapsulated reed switch 10 and complete a circuit to a solenoid 5 to open a spring loaded valve 27 to permit oil to flow from a reservoir through a pipe 13 and a non-return ball valve drain plug 14 or an adapter 18 to the sump 19.

Title: An improved process for the manufacture of soap
IPC: C11D13/02
Filed: 1921-06-22
Abstract: A fat stock, for example a mixture of equal parts of cocoanut or palm oil and pressed tallow, is saponified with a considerable excess of soda lye, amounting preferably to 1-2 parts by weight of caustic soda to 1 part of fat.  From one-third to one-fourth of the excess caustic soda may be replaced by its equivalent of sodium carbonate. Preferred quantities for 1 kg. of fat are 0.750 kg. of caustic soda, 0.265 kg. of sodium carbonate, and 8-10 kg. of water.  The saponified mixture is concentrated with constant stirring until a granular, plastic product is obtained.  When required for use this product is mixed with 10 times its weight of boiling water, forming a solution which solidifies to a paste upon cooling.

Abstract: 1301772 Cams FIAT SpA 28 May 1971 [15 Sept 1970] 17758/71 Heading F2K [Also in Division F1] A multi-lobed cam 2 for reciprocating the pumping plunger 1 of a fuel injection pump operates via a follower comprising two rollers 7, 8 mounted on axles 9, 10 carried by a rocker arm 11, the arm 11 being provided with stub shafts 24, 24a mounted in bushed openings 27 27a in a support 12 secured to the pump body 13. Connecting rods 16 articulated between the ends of the axle 9 and a pin 17 carried by a sliding block 18 convert pivoting movement of the arm 11 into reciprocation of the block 18 and plunger 1. The provision of the stub shafts instead of a conventional pin passing between the rollers enables the latter to be of sufficient size when the cam 2 has five or more lobes. Each lobe is symmetrical about a radial line passing through its peak B. The cam profile is such that, at all times, both rollers 7, 8, make contact with the cam. Thus the first portion of the profile from a trough to half lift is first determined. Thereafter the second portion from half lift to a peak is obtained by determining the necessary profile of the second portion for continuous contact with the first roller when the other roller is in continuous contact with the first portion.

[Class 136 (i)] A general purpose bag G, which may be carried by hand, is adapted to be detachably secured to one side of the luggage-carrier of a cycle by means comprising tubes A fixed to the carrier through which are passed rods B secured to the bag. The bag is made of cloth stiffened at the base H and along the side edges J of the open end, the rods B being hinged at L on one of the edges so as to hang down, as at B<1>, against the side of the bag when carried by hand. To secure the bag to the carrier, the rods are swung about the hinges L across the open mouth of the bag and engaged in slots in catches M fixed to the other edge J. Stops N fixed on the rods abut the catches M to hold open the mouth of the bag and the parts of the rods projecting beyond the catches are then passed into the carrier tubes A. One or more turnbuttons C prevent separation of the bag and carrier. The tubes A may be formed integral with the carrier or each tube may be adapted to be secured to existing carriers by a pair of brackets, one of which is rigidly secured at one end of the tube for attachment to one side of the carrier and the other slidable on the tube for attachment to the other side of the carrier, thus allowing the tubes to be fitted to carriers of different widths.

Title: Fractional distillation
Inventor: MUELLER WALTER ADOLF
IPC: B01D3/14
Filed: 1961-05-17
Abstract: 981,572. Fractional distillation columns. PLANEX ASSOCIATES Ltd. May 17, 1962 [May 17, 1961], No. 17962/61. Heading B1B. In a fractional distillation column wherein the feed mixture is introduced into the middle section, the horizontal cross-sectional area of the top and/or the bottom section of the column decreases progressively with increasing distance from the middle section ; and heat exchange means are located in or surround the section of progressively decreased cross-sectional area to maintain the vapour flow in that section proportional to the ratio of the horizontal crosssectional area to the pressure in that section. The bubble cap column shown in Fig. 2 is suitable when the desired product is the less volatile fraction of the feed mixture, which is introduced into the column through inlet 51. The liquid on the bubble cap plates in section 3 is heated by unit 1 to maintain the required vapour flow in that section. The column shown in Fig. 5 is used when pure products are required from both the top and the bottom of the column. The feed to the middle section of the column passes from the closed container 18 through the heat exchanger 17 and thence into the column. Fractional distillation occurs, the liquid passing down section 11 being heated, and the vapour passing up section 12 being cooled, to maintain the correct vapour flow/ cross-sectional area relationship. The reflux is collected by the baffle 16 and funnel 15 and is passed into container 18 via heat-exchanger 17, thus displacing further feed into the column. The vapour from the top of the column, and the residue from the base, are each extracted by a system comprising a condenser 23, receiver 22 and pump 21. The pumps 21 also pump mercury 20 into container 18 at such a rate as to compensate for the quantity of the products withdrawn from the column. A third embodiment, suitable for the progressive distillation of heavy water, comprises a series of units, each of which comprises a column (Fig. 7) packed with vertical sheets of aluminium foil 32 (Fig. 9) suspended by wires 33 from points of support 35 located above the condenser in the top of the column. Water vapour enters the column via inlets 26 and condenses on the tubes of the condenser, the condensate being directed from two sets of the tubes on to alternate sheets of the foil where it flows down under gravity as thin films of liquid. On reaching the lower section 24 of the column, these liquid films are subjected to heat from the corrugated surface 60 of the steam reboiler in order to maintain the correct vapour flow/ cross-sectional area relationship. A thin net of aluminium wire extends over the reboiler surface. The residue, enriched in heavy water, is withdrawn from outlet 28, and the vapour depleted in heavy water is withdrawn from the top of the column at outlet 27.
