A method of drawing aluminium clad steel wire W comprises grit-blasting the wire, and passing it through a mass of finely divided soap powder, through a pressure die and then through a reducing die, the pressure die and reducing die being sealed together in coaxial relationship. The grit blasting operation is carried out with a liquid suspension of aluminium oxide particles in the size range 120 mesh to 240 mesh, discharged through a nozzle by an air-jet. When the wire is travelling at high speed the lubricant may cavitate and the soap powder L is contained in a box which has a porous false bottom 33 to which pressure air can be supplied through a conduit 36. A die carrier 40 is supported by the wall 26 of the box and receives a die head 42 which contains the pressure die 44, a sealing and spacing ring 46 and the reducing die 45. The pressure die opening is 2 to 3% larger than the diameter of the wire and the reducing die produces a reduction of 20 to 25% in the cross-sectional area.

Patent GB-732988-A (GB)
Title: Improved process for extracting valuable components from fats and oils
IPC: B65B9/08
Filed: 1952-09-24
Abstract: Vitamins and sterols are extracted from animal or vegetable fats or oils by saponifying the fats or oils with an aqueous solution of sodium hydroxide of such a concentration that a solid soap containing less than 20 per cent water by weight is obtained, after cooling, subdividing said soap to uniform solid soap particles and extracting the soap particles with a water-miscible aliphatic ketone or water-miscible aliphatic monohydric alcohol in such quantities that the water content of the solution is less than 5 per cent by weight when equilibrium is reached.  The water miscible solvent may be acetone, methyl ethyl ketone, methanol, ethanol or isopropanol.  The process may be modified in that the saponification is carried out with aqueous sodium hydroxide of such a concentration that a soap containing more than 20 per cent of water by weight is obtained, and the soap so obtained is dried and subdivided to obtain uniform soap particles containing less than 20 per cent water.  The aqueous sodium hydroxide solution may contain between 40 and 60 per cent by weight of sodium hydroxide. A saponification catalyst, e.g. 1 per cent by weight of a monohydric alcohol, may be used in the saponification step.  Some glycerin is extracted by the solvent and may be recovered by extracting the extracted matter after the removal of the solvent with small quantities of water.  One detailed example is given.

Title: Improvements in the production of amides
Inventor: BARNETT CYRIL
IPC: C07D201/06
Filed: 1952-09-25
Abstract: Amides are prepared from the corresponding ketones by heating the ketone together with hydroxylamine, an acylating agent and a Beckmann transforming agent, e.g. sulphuric acid.  The process is particularly applicable to the preparation of lactams from cyclic ketones.  Acetic anhydride is a suitable acylating agent but instead of hydroxylamine and an acylating agent a reaction product thereof, e.g. acethydroxamic acid or its acetate, may be used. Acetic acid or a chloracetic acid may be present.  The temperature is preferably from 120 DEG  to 140 DEG  C.  Examples are given of the preparation of caprolactam by heating cyclohexanone with hydroxylamine sulphate, acetic or chloracetic acid, and acetic anhydride with or without additional sulphuric acid; and by heating cyclohexanone with acethydroxamic acid acetate, acetic acid and acetic anhydride.  A further example shows the production of N-isopropylisobutyramide from di-isopropyl ketone, hydroxylamine sulphate, acetic acid, acetic anhydride and sulphuric acid.  Similarly benzophenone may be converted into benzanilide, diethyl ketone into propionethylamide and cycloheptanone into the corresponding lactam.  Specification 750,222 is referred to.

Title: Machine for dispensing coinage change
IPC: G07D1/04
Filed: 1974-05-31
Abstract: 1467836 Change machine J C WOODHOUSE 31 May 1974 [8 June 1973] 24241/74 Headings G4X and G4V  A machine for dispensing coinage change, includes means to receive a coin for which change is required, means operative in response to the receipt of a coin to advance a conveyer means 23 beneath a plurality of change coinage supply tubes 62 and means 89, 18, adapted to receive and deliver change from said conveyer means, wherein there is at least one row of tubes extending in the direction of motion of the conveyer means, the or each row containing a plurality of supply tubes, the conveyer means being adapted to collect coinage from an advanced tube only after a trailing supply tube in a particular row fails to deliver a coin for collection by the conveyer means. The conveyer is driven in incremental steps and has pockets or recesses 61 arranged therein for the reception of coins. The pockets are arranged in rows. As an empty pocket passes beneath a tube it is filled. A filled pocket prevents coins from further tubes being accepted. In Fig. 3 the pulleys 24, 25 are driven anticlockwise. When all the tubes are empty biased rods 64, 65, 66 drop into the first empty recess. This jams the conveyer and via leg 71 of member 69 and pivoted closure plate 73 shuts off coin receiving slot 14. The conveyer is driven by knob 13 through drive mechanism 22. A coin received by the machine passes to cavity 27 where it prevents pin 38 mounted on pivoted lever 39 from engaging abutments 36, 37. The abutments prevent actuation of the knob without deposit of a coin. There is a clutch mechanism 41 which allows drive in one direction only. An arcuate tooth member 48 co-operates with a stop 88 to limit the maximum rotation of knob 13 and also co-operates with a non-return mechanism 50 so that the knob has to be turned through the maximum rotation before it can return. At the maximum rotation the coin drops from cavity 27 into a coin box and spring 53 returns the drive mechanism to its start position. In an alternative embodiment the rows of tubes form circles. A rotatable plate is positioned below the plate with holes that accept coins. Below the plate is a support member that is also circular but with a cut out sector to allow coins to pass to a collection shoot. The machine may be used in conjunction with a telephone call box where change for use in making a call can be obtained from the machine, and the coinage fed for making the call can be used to partially replenish the supply tube.

Abstract: 722,021. High-frequency filters. GENERAL ELECTRIC CO., Ltd., and SMALL, G. F. Jan. 19, 1953 [Oct. 17, 1951], No. 24289/51. Class 40 (8). A filter unit comprises two hybrid structures 1, 2, each of which is formed by a closed loop 3 of coaxial transmission and which are mounted so that the loops lie in parallel planes, the loops being connected by a pair of coaxial cables of equal length 8, 9 in each of which is positioned a band-rejection filter. If the loops 3 are arranged to have a circumference of 6#/4 and the terminals 4, 5, 6, 7 are spaced by a distance of #/4, where # is the centre wavelength of the transmitted signal, a signal applied at the terminal 4, in the case of structure 1, will be distributed between the lines 8, 9 and no signal will appear at the terminal 7. The structure 2 behaves in a similar manner and combines the signals passing in anti-phase over lines 8, 9 in such a manner that the output signal appears at 5 and no signal appears at 6. Filters 11, 12 are positioned at distances from the terminals 5, 6 differeing by # 1 /4 where # 1  is the centre frequency of the band to be rejected. The rejected frequencies are thus reflected back to the terminals 5, 6 in phase and combine at the terminal 7. The filters 11, 12, Fig. 2, consist of the coaxial stubs described in Specification 696,394 spaced apart by a distance of #/4. They are bolted to the transmission lines 8, 9. The hybrid structures 1, 2 are each formed of two parts 15, 16 and 17, 18, the mating surfaces of which have annular grooves forming the outer conductors of the coaxial loops. The parts 8, 9, 16, 18 form a unitary structure made as a single casting with the parts 8, 9 in the form of solid rods. These rods are drilled out and inner conductors with their spacers inserted into the bores. The inner conductors of the hybrid structures 1, 2 are then placed in position and the parts 15, 17 screwed in place. Specifications 659,812 and 702,568 also is referred to. Reference has been directed by the Comptroller to Specification 664,688.
