Title: Improvements in or relating to receptacles for betting slips
IPC: B65D30/00
Filed: 1927-08-20
Abstract: 299,130. Harvey, W. C. Aug. 20, 1927. Fastenings for bags. - Relates to bags for holding betting slips. The slips may be con- - tained within a pouch portion K, Fig. 5, adapted to be tucked within the bag J, the mouth of which is provided with a series of eyelets L through which a pin M can be threaded to draw the mouth together and close the bag. To prevent unauthorized access to the slips the pin is subsequently passed through co-incident holes in a looking device and is held secured thereto upon inward movement of the slide. The locking device consists of a casing having at one side a window B, Fig. 3, and having the sides provided with the co-incident holes C before mentioned. Within the casing is a slide E formed with teeth F along the edges, having near one end an elongated slot G and near the other a space H bearing the code H<1>. The slide is originally set against the right hand edge of the casing, see Fig. 1, which is surrounded by a paper seal. The inward movement of the slide referred to above, produced say by means of a match, causes the narrow part of slot G to come opposite the openings C and so prevents withdrawal of the pin M, by reason of the enlarged head P. This movement also brings the code H<1> opposite the window B, enabling it to be signalled by the operator. As the springs D on the casing engages with the teeth of the slide it cannot be retracted and a. stop pin Q inserted through a hole I in the casing engages the end of a recess R and presents further forward movement. To gain access to the bag on arrival at its destination, the paper seal surrounding the casing is removed and the stop pin Q withdrawn from the hole. The slide can then be pushed further towards the left-hand end of the casing and the pin P withdrawn through the holes C and the right-hand enlarged part of the slot G.

Abstract: 1,140,199. Water circulation system for swimming bath. LIFETIME METAL PRODUCTS Inc. 17 May, 1966 [20 May, 1965], No. 21969/66. Heading A4N. A swimming pool has a peripheral gutter formed between the side wall of the pool and an enclosed water supply conduit. Fig. 2 is a cross-section of a gutter according to the invention in which walls 12, 38 and 39 define the gutter 11. The inner wall 12 of the gutter comprises a conduit 13 for supplying filtered water to the pool via nozzles 28 which are spaced at regular intervals along the conduit. A sacrificial anode 31 is provided within at least part of this conduit. Notches provide a passage between the pool and the gutter and are formed in removable sections providing access to the interior of the conduit - and allowing introduction of anodes into the conduit and are preferably placed near to each of the corners of the pool. Fig. 3 is a perspective view of one such notch 50 which creates a top edge 51, side edges 52 and a bottom edge 53. A base plate 56 and walls 54 and the top plate 60 define the scope of the notch and leave a transverse opening (68) which may be closed by a gate 67 which can be locked by means of arm 70 in either the completely open or completely closed positions. When the bath is in use, the water level is just below the top of the inner gutter 12, and the gate 67 is closed so that the gutter receives only the overflow resulting from disturbance of the water surface. When the bath is not in use the gate 67 is opened to allow skimming of the surface water and debris which passes into the gutter and thence to a filtration and cleansing system before being re-circulated to the pool via conduit 13 and nozzles 28 (Fig. 1, not shown).

Title: An improved process for the production of terpene alcohols
IPC: C07C35/30
Filed: 1924-09-19
Abstract: b -Pinene is employed as the starting material for the production of terpene alcohols.  When heated with organic acids soluble in water, such as acetic or butyric acid, terpenyl esters are formed, from which terpineol can be obtained.  Bornyl and isobornyl esters, however, are produced when substituted aromatic acids insoluble in water are used, provided that a catalyst such as the mixed anhydride of boric and acetic acids is present. According to the example, b -pinene is heated with salicylic acid or dichlorobenzoic acid in the presence of a little boroacetic anhydride dissolved in glacial acetic acid.  The bornyl esters formed are then saponified with caustic soda to produce borneol. Specifications 26785/03, 16532/07, 11248/08, 18049/08, and 144,604 are referred to.

Title: Improvements in or relating to the treatment of cellulose esters
IPC: C08B3/22
Filed: 1934-07-31
Abstract: Cellulose triacetate is subjected to regulated heating in solid form, i.e. without first dissolving it or suspending it in a liquid medium, with a substantial quantity of an alcohol having a solvent or swelling action on the triacetate, in the presence of a small amount of an acid, catalyst such as sulphuric or phosphoric acid, the temperature and duration of the treatment being regulated to produce either an acetate which is still soluble in methylene chloride or methylene chloride and alcohol although with increased viscosity but insoluble in acetone, or an acetate which is itself soluble in acetone, while a film cast from the acetone solution and dried is no longer soluble in acetone.  Suitable alcohols are ethyl, propyl, butyl, isobutyl, amyl, or benzyl alcohol, or cyclohexanol.  Mixtures of these acids may be employed.  If the alcohol has a swelling but no solvent action, the partially de-esterified cellulose acetate may be separated by simple mechanical means.  If the alcohol has a solvent action on the cellulose acetate it must be reprecipitated after the de-esterification with a non-solvent miscible with the alcohol and the ester formed during the de - esterification.  Suitable precipitants are methyl alcohol or benzene.  In an example, 10 parts of cellulose triacetate were treated for 2\ba1/2\be hours at 100 DEG C. with 150 parts of normal butyl alcohol and 15 parts of orthophosphoric acid of 80 per cent strength.  At the end of the process, the triacetate was still insoluble in acetone, but the viscosity of its solution in methylene chloride had increased by about 20 per cent.  In other examples, 10 parts of cellulose triacetate were heated for 2\ba1/2\be hours at 76 DEG  C. with 100 parts of ethyl alcohol and 3 parts of 67 per cent nitric acid ; or for 10 hours at 93 DEG  C. with 100 parts of propyl alcohol and 8 parts of 80 per cent orthophosphoric acid ; or for 2\ba1/2\be hours at 127 DEG  C. with 100 parts of iso-amyl alcohol and 8 parts of 80 per cent orthophosphoric acid ; or for 14 hours at 37 DEG  C. with 100 parts of benzyl alcohol and 1 part of concentrated sulphuric acid.  In each case the acetate after separation was found to be soluble in acetone, but a film cast from the acetone solution was no longer soluble in acetone.  Specification 433,785 is referred to.
