Title: Improvements in or relating to the manufacture of footwear
IPC: B29D35/00
Filed: 1958-07-21
Abstract: 897,526. Moulding footwear. LUDWIG, H. July 21, 1958, No. 23264/58. Class 87(2). [Also in Group VII]. Shoes &c. having rubber or elastomeric sole are formed with a plurality of cavities on the inner surface of each of the heel, shank, and forepart portions of the sole, the cavities being defined by ribs &c. forming part of the sole and being produced during the moulding of the sole to the upper. The last 1, which may be heated electrically, has an integral or separate heel portion, and may have a heel liner 13 with integral or attached pins or calks 14 and a removable forepart and shank liner 15 attached by hooks 16, 17, or a liner 15 which covers the whole of the bottom of the last. The vulcanising mould comprises a bottom die 20, which is moved upwardly to press the sole, and disc portions 18, preferably of aluminium and heated by elements 26. To prevent excessive heating of the upper where it contacts the sealing lip 23, heat to the latter is restricted by an insulating layer, e.g. of glass wool or asbestos, or of liquid Kieselguhr injected through a bore in the mould wall, arranged between walls 28, 29 in the portions 8. Walls 28, 29 may be protected by sleeves 30 interposed between the sealing lip 23 and the portions 8. After vulcanisation the last is unhooked from liner 15 and removed, and then the liner is removed, the shape of pins 14 and a previous dusting with a rubber separating agent e.g. silicon, facilitating such removal, In the finished shoe the cavities may be covered by a cover sole of the same thickness as the liner. To reduce weight and cost a filler piece, e.g. of wood, may be vulcanised into the heel. The pins 14 project into the sole directly or through holes 10a in the insole, as shown. In the construction shown in Fig. 5 the cavity producing means comprises fixed cores 22 attached to the insole 10. Each core may comprise a sleeve with a filling 22a of a solid such as sand, or of a liquid which evaporates above the vulcanising temperature, the sleeves being impermeable to the liquid, or of a gas, e.g. air. Alternatively the cores may be of solid material which evaporates at the vulcanising temperature, and which may or may not be enclosed in a sleeve. The core fillings may be removed after vulcanisation through holes 10b in the inner sole, and a cover sole 12 then inserted. Specification 763,847 is referred to.

Title: An improved process for evaporating wood sugar solutions in concentrated hydrochloric acid
IPC: C13K1/02
Filed: 1936-08-24
Abstract: In the vacuum evaporation or spray drying by means of hot air, of hydrochloric acid-containing sugar solutions derived from wood, the gas and steam evolved in either case is utilized to preheat the solutions so as to remove sufficient of the hydrochloric acid to enable the gases evolved from the subsequent vacuum evaporation or spray drying to be completely removed in a condenser.  In the former method of working, the fresh solutions may be preheated indirectly by passing the vapours through acid-resisting tubes immersed therein; in the latter direct preheating may be used by contacting the solutions with the vapours.ALSO:In the vacuum evaporation or spray drying by means of hot air of hydrochloric acid-containing sugar solutions derived from wood, the gas and steam evolved in either case is utilized to preheat the solutions so as to remove sufficient of the hydrochloric acid to enable the gases evolved from the subsequent vacuum evaporation or spray drying to be completely removed in a condenser.

Title: Improvements in or relating to reciprocating pumps and compressors
IPC: F04B3/00
Filed: 1947-08-22
Abstract: 655,343. Reciprocating pumps and compressors. YATES, D. H. Aug. 22, 1947, No. 23368. [Classes 8(i) and 102(i)] In a compressor or pump of the kind comprising a casing E in which reciprocates a chambered ram D having in its chamber a slide block C reciprocated transversely of the direction of the movement of the ram D, both the ram and slide block being operated by a single crank or eccentric B, the slide block serves both as a piston for the fluid entering and leaving the ram chamber and as a valve to co-operate with ports in the ram chamber wall by sliding contact past such ports whilst the ram co-operates with ports in the casing. During the suction stroke, Fig. 2, fluid is drawn through an inlet port F in the casing, a port G in the ram, a space M below the slide block, a channel C' in the slide block and a port H in the slide block into the pumping chamber J and is delivered therefrom during the delivery stroke through port H, another channel C<SP>1</SP>, a space N above the slide block and a port K in the slide block to the outlet opening L. The pump may be made double-acting by an arrangement of ports in the casing end covers, as shown in Fig. 5; fluid enters the pump chamber K<SP>1</SP> through an inlet F<SP>1</SP> in one casing end cover, channel C<SP>1</SP> and port H<SP>1</SP> in the ram and is delivered through port H<SP>1</SP>, an L-shaped duct M<SP>1</SP> in the slide block and an arcuate slot O in the other casing end cover; the other end of the pump is similarly arranged and suction and delivery .take place alternately from pump chambers K<SP>1</SP> and L<SP>1</SP>. The pump may be arranged for high pressure delivery by reducing the cross-sectional area of chambers K<SP>1</SP> and L<SP>1</SP> and providing co-operating hollow projecting portions on the ram D to reciprocate therein.

Title: Information storage system
IPC: G11B20/18
Filed: 1973-05-17
Abstract: 1404541 Recording data; avoiding defects INTERNATIONAL BUSINESS MACHINES CORP 17 May 1973 [7 June 1972] 23607/73 Headings G4A and G5R Data is recorded serially in tracks along a record medium, e.g. magnetic disc, each track having a pre-recorded indication of whether it contains a defect rendering a portion of the track unusable and of the distance of the defect from a fixed reference point, and the recording system includes control means responsive to the pre-recorded defect indication to record data in such a way as to avoid defects. Each track of a magnetic disc includes a pre-recorded field indicating whether the track contains a defect and the distance of such a defect from an index mark denoting the start of the track. The data is recorded in record blocks separated by gaps, each block including a control field, and one or more further fields, including data fields, separated by gaps. The control field includes an indication of the lengths of various parts of the block together with address information and an indication of the distance from the block to the defect (if present), the last value being recalculated and recorded as each new block is recorded. A check is made for each block as to whether the defect will affect its recording by comparing the calculated defect distance and the block length. If a block would be affected a check is made to determine whether the defect will be wholly contained within an inter-field gap, whether the defect can be avoided by extending one of the gaps by a fixed length along the track, or whether it will be necessary to split one of the fields and introduce a gap of the fixed length. If the defect lies within a gap no action is taken and the block is recorded normally, otherwise the disc is carried through a complete revolution and the control field is re-recorded to indicate what action is being taken and the block is recorded appropriately. The control field is used to control the corrct read-out of shifted and split fields.
Patent GB-461896-A (GB)
Title: The manufacture of compounds of the cyclopentano polyhydro phenanthrene series
IPC: C07J1/00
Filed: 1935-08-22
Abstract: Keto - cyclopentanodimethyltetradecahydrophenanthrols are prepared from pregnanolones by a process which comprises converting the latter into secondary-tertiary dialcohols, splitting out water from the tertiary hydroxyl group and the adjoining hydrogen atom, followed by a removal of the side chain at the double bond by the action of oxidizing agents characterized in that the removal of water is accomplished without simultaneous acylation of the secondary alcohol group, and preferably by a dry heating of a Grignard reaction product with excess of a Grignard reagent, for example in a high vacuum under reflux.  The splitting up of the double bond is preferably carried out by means of ozone, but other oxidizing agents such as permanganate, and chromium trioxide may be used.  When ozone is used, the ozonide is preferably split by a reduction method, using a platinum catalyst, and shaking an ethyl acetate solution in a hydrogen atmosphere. In an example, allo-pregnanol-(3)-one-(20) is treated with magnesium methyl iodide.  Water is split off from the tertiary alcohol so produced by heating at 110 DEG  C. for one hour under reflux in a high vacuum.  The dehydrated product is treated in chloroform solution with ozone, and the ozonide decomposed by heating at 50 DEG  C. with glacial acetic acid to give the required hydroxy - ketone - (3 : 17).  If, however, the ozonide is split by shaking with a platinum catalyst in ethyl acetate solution in an atmosphere of hydrogen, there is obtained the corresponding di-secondary di-alcohol.  Specification 449,326 is referred to.  A sample has been furnished under Sect. 2 (5) of trans-androsterone made as follows. Allo-pregnanol - (3) - one - (20) is treated with magnesium methyl iodide, the product dehydrated by heating in a vacuum under reflux, and then treated with ozone.  The ozonide on heating with glacial acetic acid gave the required product.
