Patent GB-689622-A (GB)
Title: Process of rendering flavors accessible in nut butters
IPC: A23L25/10
Filed: 1948-07-02
Abstract: In order to overcome flavour deficiency in a nut butter or spread, there is introduced some or all of the flavour solvent originally present in the nuts, and if desired, other flavour solvent, in the presence of a dineric interface modifier acting as an emulsion stabilizer and comprising a component which is predominantly hydrophilic, e.g. sodium propyl sulphate or cholesterol, and a component which is predominantly lipophilic, e.g. melissyl betaine chloride or lecithin.  The nut butters or spreads include products prepared from seeds such as soya beans in a manner similar to the preparation of peanut butter from peanuts.  The flavour solvent may be water, an oil, hydrogenated oil, fat or wax, a dispersion of oil, fat, or wax in water, or a dispersion of water in oil, fat or wax. Formation and stabilization of the mixture may be assisted by subjection to sonic or ultrasonic vibrations.  The process prevents settling out of added flavourings such as salt, sugar, and chocolate.

Title: Improvements in or relating to methods of and apparatus for forming undercut socketsin a glass body in a hot plastic state
IPC: C03B23/00
Filed: 1945-07-13
Abstract: 596,019. Glass-working. PILKINGTON BROS., Ltd., WILCOCK, J. E., and BAILLIE, G. H. July 13, 1945, Nos. 17979/45 and 24040/46. [Class 56] Comprises apparatus for undercutting a preformed socket in a dish-shaped high voltage glass insulator by moving a shaping stick within the socket whilst the glass is still plastic, the stick traversing circular paths, around the axis of the socket, with regularly increasing diameters. During such movement the stick is rotated on its own axis by rolling on the glass. In the form shown, the inclination of the axis of the stick increases with the increase in the diameter of its path ; in another form, the stick remains vertical. The undercut portion of the socket serves as a load-bearing shoulder for a pin cemented into the socket. In the form shown, the stick 1, the lower end E of which forms the undercut portion B of the socket in the insulator A supported in a mould C, is carried in a stationary universal bearing 2, 3 and passes through a ball-bearing 1a carried in a slot in a bevel-wheel 6. The bevel-wheel carries a cage 9 which supports a bearing 1a<1> for the upper end of the stick, which bearing is urged by a spring 10a so that a projection 10 therefrom engages a snail cam 12 also carried by the cage. The cam is slowly rotated by a pawl on the cage rotating a ratchet-wheel 13 one step per revolution of the bevel-wheel, the eccentricity of the cam decreasing with its rotation so that the upper bearing of the stick is moved more and more away from the axis of the bevel-wheel, the stick tilting about the bearing 2, 3. The ratchet also winds up a clock spring 18 which is released, when the stick is recentred after having reached maximum eccentricity, to restore the cam 12 quickly to its position of maximum eccentricity, i.e. that in which the stick is coaxial with the bevelwheel. The stick is recentred by moving the frame 5, carrying the bevel wheel, upwardly, whereby a conical seating 19 in the frame engages a conical collar 20 on the stick to swing the latter back into central position.

Abstract: 1,109,973. Seaming & folding edges of non- metallic sheet material. BRITISH RESIN PRODUCTS Ltd. 24 Feb., 1967 [26 April, 1966], No. 18146/66. Heading B5K. A fixed fold is formed in an article made from a foldable thermoplastic material by folding the material to the desired position, holding the fold in this position and treating the held fold with mechanical vibrations of ultrasonic frequency for sufficient time to fix the fold in position. The thermoplastic material may be a polymer formed by addition polymerizing a compound containing ethylenic unsaturation, e.g. polyethylene or polypropylene. The invention is applicable to forming the closure of a filled container by securing a folded-over rim. A sporting shotgun cartridge ease made from polyethylene having a density in the range 0À94 to 0À965 and a melt index in the range 0À1 to 5À0 is formed by folding the open end of the case so that the fold abuts on overshot card and fixing the held fold using vibrations in the frequency range of 19-90 kilocycles per second. The fold may be held by a groove in the overshot card or by an insert such as a metal or plastics ring. Alternatively, the fold may be held in position by hand, by an adhesive or by a jig. The ultrasonic vibrations are produced by apparatus having a piezoelectric transducer.

Title: Improvements in and relating to Protective Devices for Electric Circuits.
IPC: H01H83/08
Filed: 1916-12-19
Abstract: 110,247. British Thomson-Houston Co., (General Electric Co.). Dec. 19, 1916. Protective devices. -Reverse power relays of the dynamometer type have their coils so arranged and connected in the circuit to be protected as to be insensitive to reversals accompanied by a slight drop of voltage, such as often occur in synchronizing operations, and very sensitive to reversals accompanied by a great drop in voltage, such as are due to short-circuits. The relay comprises a fixed current coil 1 energized by a current transformer 7 and a fixed potential coil 2 energized by a voltage transformer 9, the two coils 1, 2 being in inductive relationship the potential coil normally assisting the current coil but on reversal opposing it with a force proportional to the potential. The moving coil 3 cr,nstitutes a second potential element either connected in series with the coil 2, as shown in Fig. 2, or energized by a separate potential transformer. It produces a field co-acting with the resultant field of the other two coils and normally tending to maintain the contacts 4 and 5 apart assisted by the spring 6. With reversal accompanied by a large voltage drop, the coil 3 moves against the action of the spring 6 to complete the tripping circuit at the contacts 5. Specifications 19603/05 and 16575/14 are referred to.

Title: Improvements in or relating to toric race transmission units
Inventor: ARMSTRONG JOHN NOEL
IPC: F16H15/38
Filed: 1964-05-01
Abstract: 1,032,004. Variable-speed friction gear. NATIONAL RESEARCH DEVELOPMENT CORPORATION. April 27, 1965 [May 1, 1964], No. 18306/64. Heading F2D. A transmission has driving and driven toric discs 5 engaged by precessional rollers 1, 2, 3 in carriers 10, 11, 12 each mounted by ball joints 11, 12 on pistons 13, 14 slidable in blocks 25, 33, 44 secured to a fixed spider 26, the transmission including damping means comprising piston extensions 21, 22, 35, 38 in chambers 23, 24, 36, 39, the leading chambers, e.g. 23, of roller 1, being connected to the trailing chambers, e.g. 36, of the next roller 2 by passages 45, 46 and a chamber 47. Should only one roller be moved out of its equilibrium position, in which its rotational axis intersects the main axis of the transmission, then the fluid is forced out of chamber 23, for example, and escapes by a restrictive passage, not shown, to dampen this movement. However if fluid is admitted to the chambers 15 or 16 of all the rollers to move them all out of the equilibrium position so that they steer themselves from one ratio attitude to another ratio attitude, the fluid expelled from one leading chamber 23 passes to its associated trailing chamber 36 so that the damping means is ineffective. Actuation of pistons 15 move the rollers so that they adopt a higher ratio position and actuation of pistons 16 produce a lower ratio position of the rollers. The chamber 47 is connected to a lubricant pressure line through non- return valve 49. The planes containing the axes of the trailing piston and of the leading pistons are on opposite sides of the plane containing the torus centre circle, so that the line joining the centres of balls 11, 12 of each carrier makes an angle (the chamber angle) with this latter plane. In Fig. 2 (not shown), the pistons of the damping means are separate from the actuating pistons and are engaged by extensions of the carriers adjacent the roller axes, this extension being arcuate to remain in contact with the damping pistons when the roller tilts for changing the transmission ratio. In a transmission of this latter form in Fig. 3 (not shown), there are two parallel adjacent damping pistons and cylinders adjacent each end of the carrier and the transmission includes four discs and two sets of rollers so that not only is one set damping cylinders of each roller set connected as above but the second sets of damping cylinders of each set of rollers are interconnected. Figs. 4 and 5 (not shown), show two ways in which the damping means of adjacent sets of rollers are interconnected; in Fig. 5 some of the damping cylinders in each set are interconnected as in Fig. 1.
