Title: Improvements in and relating to liquid level operated electric switches
IPC: G01F23/18
Filed: 1934-01-16
Abstract: 430,101. Actuation of switches. GINGER, J. E. W., 28, Woodland Drive, Watford, Hertfordshire. Jan. 16, 1934, No. 1551. [Class 38 (v)] A switch operated by a general change in liquid level, e.g. the level of oil in the sump of an engine of a road vehicle, but not affected by sudden changes of level due to the vehicle passing over a bumpy road, comprises a float 5 moving in a cylinder 1 in the sump 2, the cylinder having small holes 4 through which oil can pass. The small holes 4 prevent sudden movements of the float 5 but a general fall in level of the oil causes a projection 11 on the float to engage a diaphragm 6 which then presses together two contacts 9 to close an alarm circuit. In a modification, Fig. 2, (not shown), the switch is situated above the float and is operated by movement of a plunger connected by a spiral spring to the float.

Title: Clasps for containers
IPC: A45C13/04
Filed: 1954-01-19
Abstract: 775,299. Handbags. FERMOIR FRANCAIS. Jan. 19, 1954 [June 15, 1953], No. 1559/54. Class 133. [Also in Group XXV] A clasp for bags and like containers includes two strip-like frame sections A<SP>1</SP>, A<SP>2</SP>, through the co-operating ends of which are inserted pivots, 0<SP>1</SP>, 0<SP>2</SP>, extending perpendicularly to their longer surfaces, wherein each of the frame sections consists of two outer rigid portions, and at least one intermediate rigid portion, the adjacent ends of the rigid portions of each section being connected by spring portions resisting both flexional and twisting stresses. As shown each section consists of a spring blade al or a2 the centre portion and end portions of each being made rigid by strips b<SP>1</SP> and c<SP>1</SP> or b<SP>2</SP> or c<SP>2</SP> to form the rigid end portions, and a single intermediate rigid portion, the portions of the strips between the rigid strips then constituting the spring portions. When the sections are separated they define a rectangular opening with rounded corners and will stay apart if the friction between the ends is sufficient to overcome the flexional stress on the spring blades. On pressing them together a point is reached when the flexional stress overcomes the friction, so that the clasp then automatically closes. As shown the frame sections overlap and to allow for this the pivots 0<SP>1</SP>, 0<SP>2</SP> pass through elongated slots in the section A2. In a modification the sections are side by side and the ends of the sections are either offset or connected by a short strip. Tabs t<SP>1</SP>, t<SP>2</SP> are provided for pulling the sections apart and guide plates may be attached on one of the sections when the clasp has the sections arranged side-by-side so that when they are together they are in alignment. The sections A1, A2 may also be made by rivetting springs to the rigid portions which are then of channel shape. The spring portions or the whole of the sections can be enclosed in

Patent GB-719093-A (GB)
Title: Production of artificial films
Inventor: O'HANLON AIDAN FRANCIS
IPC: B29C48/08
Filed: 1952-01-23
Abstract: <PICT:0719093/IV (a)/1> <PICT:0719093/IV (a)/2> A film of a synthetic linear polymer is obtained by extruding the polymer in molten state and passing the molten film downwardly into a pool of cooling liquid which is maintained in the nip formed between two contra-rotating rolls, the two rolls being rotated at equal peripheral speed and each roll, at the nip, being rotated in the direction of travel of the film which is passed through the nip.  The nip rolls may be immersed to a depth less than their diameter in a bath of cooling liquid and a film of liquid may be allowed to travel round the rolls and into the nip to form and maintain the pool of cooling liquid.  A wetting agent may be added to the liquid to ensure that sufficient is carried into the nip.  Alternatively the pool may be formed by spraying the liquid on to the rolls or on to the molten film before the film reaches the nip.  The cooling liquid maybe water, glycol or glycerol.  Any tendency for the cooling liquid to be so heated by the molten film as to boil locally may be removed by providing cooling devices close to the surface of the film, e.g., refrigerator tubes, containing a chilled circulating liquid such as methanol, may be placed on each side of the film close to the surface thereof and extending across the width of the film. Alternatively, the nip rollers may be chilled by internal circulation of a chilled liquid.  Cooling may also be accomplished by removing liquid, which has become heated, at each side of the film from the portions of the pool directly between the film and the rolls.  This liquid may be removed at a plurality of points spaced across the width of the film, or it may be removed from a continuous area extending across the width of the film in a position as close as possible to the film.  Cooling liquid may be allowed to flow from the ends of the nip at a rate controlled, e.g. by means of adjustable end plates, so as to give a pool of substantially constant depth in the nip.  The polymer of which the film is formed may be a linear condensation polyester, such as polyethylene terephthalate, or a linear condensation polyamide. As s own in Figs. 1 and 2, the freshly extruded molten film 1 passes to the nip of steel rolls 2, which are immersed to a depth of about two thirds of their diameter in water contained in bath 3.  Cold water supplied through inlet 4 flows through the bath and out by the adjustable overflow 5.  Water is carried on the surface of the rolls to collect as a pool 6.  The level of the liquid in the pool is maintained by end plates 7.  Suction tubes 8 provided with a series of downwardly facing holes enable water to be drawn away from the pool in the region of the film surface.  The process is carried out so that the rate of supply of cooling liquid to the pool is sufficient to ensure adequate cooling and solidification of the film but not so high as to produce turbulence at the surface of the pool. Films free from corrugations and surface blemishes may thus be obtained.

Patent GB-878090-A (GB)
Title: A process for preparing an unsaturated polyester resin
IPC: C08G63/52
Filed: 1959-01-21
Abstract: An unsaturated polyester having a high viscosity and softening temperature and an improved flexural and impact strength is made by condensing a polyhydric alcohol with isophthalic acid to form a polymeric product, and thereafter condensing this product with an unsaturated aliphatic polybasic acid (e.g. maleic or fumaric acid). Preferably 0,5-4,0 mols of isophthalic acid is used per mol of unsaturated acid.  The polyhydric alcohol is preferably a glycol (e.g. ethylene, propylene, diethylene or triethylene glycol); if desired in admixture with a small amount of a higher polyhydric alcohol (e.g. glycerol or pentaerythritol).  The polyester may be modified with other acids (e.g. succinic, adipic, azelaic or sebacic acid).  The polyester may be copolymerized with styrene, mono- or polyalkyl styrenes, mono- or polychlorostyrenes, vinyl esters, vinyl ketones, vinyl ethers, vinylidene halides, acrylic acid and its derivatives (e.g. amides, esters or nitriles), and the diallyl, diethallyl or dimethallyl esters of saturated dibasic acids (e.g. diallyl phthalate, adipate, sebacate or glutarate).  A suitable copolymerization catalyst is a mixture of benzoyl peroxide, methylethylketone peroxide and cobalt naphthenate.  Para-t-butyl catechol may be added as inhibitor.

Title: Improvements in endless-track vehicles
IPC: B62D11/22
Filed: 1928-01-24
Abstract: 286,245. Venzlaff, R., Buck, O., and Agahd, W. March 1, 1927, [Convention date]. Relay or power apparatus.-In an endless-track vehicle of the kind steered by lateral distortion or flexure of the tracks, power for steering is derived from the propelling engine. In the construction shown in Figs. 2 and 3 the ground rollers 5 are carried by axles 4 which can slide transversely on rollers 3 in the frame 1, springs 5<a> and swivelling connections being provided between the rollers and the axles. Pins 6 on the axles 4 work in inclined slots 7 in a plate 8 guided longitudinally of the vehicle so that when this plate is moved the axles 4 are displaced laterally as shown. Power for steering is obtained from the propeller shaft a by means of two trains of bevel gearing 30, 31 which drive gear wheels 16', 16 in opposite directions through clutches 18, 17 controlled by a cam 19 on the steering shaft 33. A worm 14 can thus be driven in either direction and this worm shifts the sliding plate 8 through rack gearing 29, a sliding axle b and a bell-crank lever 10. The idle sprockets 22<a> are carried by the axle b and slide with it. The driving sprockets 22 are slidably mounted on their axles b<1> and are caused to slide simultaneously with the sprockets 22<a> by means of gearing 35, 36, 37 and a rack 38. The end ground rollers 25, 25<a> are mounted on fixed axles 4<a> and are swivelled for steering by means of links 21 and levers 23 pivoted on the fixed axles and connected at 24 to the sliding axles 4. In a modification the track sprockets are not displaced but the end rollers 25, 25<a> are both displaced laterally and swivelled.
