Abstract: 1,005,101. Drill pipes; shaft couplings. FLEXWEIGHT DRILL PIPE CO. Inc. Jan. 16, 1963 [April 4, 1962], No. 1971/63. Headings F2G and F2U. [Also in Division B3] A drill pipe comprises inner and outer tubular members 12, 11 prestressed in axial compression and tension respectively, the inner tubular member at each end being a force fit, as at 16, 19, in the outer tubular member. In the construction shown, the outer tubular member 11 is provided with tapered threads and surfaces at each end to co-operate with mating threads and surfaces of the connectors 14, 15 which are screwed and shrunk on to the member. One end of each tubular member has a greater diameter than the other so that the members may be telescoped. A chamber 13 is formed between the two members 11, 12, the chamber being filled with a dense fluid, e.g. a bituminous tar with fillers, during the telescoping (Fig. 2A, not shown). The telescoping action pressurizes the fluid to between 500 and 15,000 p.s.i. The frictional length 16 which is to be at the lower end of the pipe in use is greater than the length 19, the frictional forces developed also being greater in that the excess diameter of the inner tube at its lower end before telescoping is greater than that at the upper end. The inner tubular member is formed at its upper end with a surface 22 adapted to transmit axial forces to the outer member through a further surface 23. Gaskets 17, 24 of an elastomer, e.g. a halogen-butadiene or a fluoro-elastomer, are provided to seal the chamber between the two members. In a modification (Figs. 3, 4, not shown), the inner and outer tubular members abut the end face of the sockets of the connectors 14, 15. Further, the connectors may be screwed and welded to the outer member 11 such that the inner member 12 also frictionally engages part of the inner surfaces of the connectors (Figs. 5, 6, not shown). The connectors may be butt welded to the end of the outer member to form a continuous inner surface (Figs. 7, 8, not shown).

Title: Improvements in or relating to the manufacture of bread
IPC: A21D2/32
Filed: 1960-01-20
Abstract: In a continuous process of making bread, which includes preliminary mixing of a fermented yeast brew with other conventional dough-forming ingredients, then mechanically working at such a high speed as to develop a soft, putty-like dough in a few minutes, there is continuously introduced into the ingredient mixture prior to the high-speed mechanical working and at a rate providing a proportion of at least 0.5% by weight of the flour employed, an organoleptically bland, finely particulate, vegetable protein material, at least 40% of the protein material having a molecular weight of 150,000 or greater.  An organoleptically bland, isolated soybean protein see Specification 901,110, [Group IV (b)] consisting essentially of substantially undenaturated protein of the globulin type, having a reactively available sulph-hydryl content of between zero to 4X10-6 moles per gram see Specification 901,110, [Group VI] only 20-30% of the protein having a molecular weight less than about 150,000, at least 40% of molecular weight 300,000 or greater and 10-20% of molecular weight 600,000 or greater, is preferred.  The protein material may be introduced as a powder of such fineness that at least 80% passes the openings of a 200-mesh screen, in admixture with the flour and other dry ingredients employed.  Relatively small proportions, preferably at least 1.0% by weight of the flour, of the protein material are added for improving the visual, organoleptic and physical characteristics of the bread, although up to 20% may be included; in the latter case a small proportion of a refined, bleached lecithin containing a substantial proportion, not exceeding one-third the weight of the lecithin, of free fatty acid is incorporated to render the resulting high-protein bread softer. Examples are disclosed.

Title: Improvements relating to the quality control of town gas
Inventor: LEWIS CHARLES HENRY
IPC: F17B1/14
Filed: 1965-01-18
Abstract: 1,073,092. Gas holders of variable capacity. NORTH THAMES GAS BOARD. Jan. 18, 1966 [Jan. 18, 1965], No. 2154/65. Heading F4X. The quality of town gas is maintained at an acceptable level by means of a system comprising a reservoir vessel 3 divided into two variable capacity compartments 6, 7, the lower compartment 6 being connected to the gas main 1 by a branch pipe 2 and a normally open shut-off valve 10 being inserted in the gas main 1 downstream of the intersection of these pipes; and the upper compartment 7 being connected by a pipe 9 to the gas main 1 at a point downstream of the valve 10; a second, normally closed, shut-off valve 11 being incorporated in the pipe 9. Quality monitors 12, 13 are connected to the gas main 1 upstream of its connection with the branch pipe 2, each in groups comprising three similar instruments. If at least two of the three indicate that gas of unacceptable quality is passing through the main 1 from the gas-making plant, the valve 10 is automatically closed and valve 11 opened, so that the unacceptable gas is diverted into the lower compartment 6 and thereby displaces acceptable gas stored in the upper chamber 7 into the gas main 1. Subsequently, when an acceptable gas supply from the gas-making plant to the main 1 has been restored, the upper compartment 7 may be replenished with acceptable gas by opening the valve 11 slightly, which action allows some of the acceptable gas to enter the upper compartment 7, simultaneously forcing the unacceptable gas in the lower compartment 6 out into the gas main where it is diluted by admixture with acceptable gas. The reservoir shown comprises a two-part cylindrical or spherical container, the compartments 6, 7 being formed by a flexible diaphragm weighted at its central portion 8, whereby the diaphragm tends to lie closely against the bottom of the reservoir. Alternatively the separating wall between the compartments may comprise a piston moving in a cylinder.

Title: Motor vehicle
IPC: B60K5/08
Filed: 1943-02-10
Abstract: 572,896. Motor vehicles. TRIGGS, W. W. (Timken-Detroit Axle Co.). Feb. 10, 1943, No. 2246. [A Specification was laid open to inspection under Sect. 91 of the Acts, Aug. 27, 1943.] [Classes 79 (ii), 79 (iii) and 79 (v)] Comprises a motor vehicle having two engines each driving a separate axle, one axle being provided with at least two gear ratios on the axle itself and the other axle having only one gear ratio which corresponds to the lower ratio of the first axle. In the construction shown in Figs. 1 to 4 a main engine 16 drives the rear axle 12 through the usual clutch and transmission gear and the axle 12 is provided with a two-speed gear 43. An auxiliary engine 17 drives the front axle 13 through a clutch 23 and transmission 24 and a single gear-ratio enclosed in a gear-box 26 housing a clutch whereby the front axle can be disconnected from its driving gear when desired. Under normal running conditions the main engine 16 only is in use, the auxiliary engine is not running, and the clutch in the front axle gear-box 26 is disengaged by a spring. The ignition switch and the clutch 23 of the auxiliary engine are controlled simultaneously by a handle 38 on a shaft 37 mounted on the steering column 34 and interlocking means are provided whereby the shaft 37 is locked when the main engine 16 is driving the axle 12 through the high-gear ratio of the gear-box 43. This is effected by means of a fork 62 formed on a rod 61 normally drawn downwards by a spring to the position shown in Figs. 3 and 4 in which it locks an arm 63 on the shaft 37 in the position in which the ignition switch of the auxiliary engine is " off " and its main clutch 23 is disengaged. The axle gear-box 43 is controlled by an arm 45 biassed to the high-gear position by a spring. When the low-gear is to be used a button 53 is pressed by the driver to operate a valve 52 so that a pipe 51 normally connected to the atmosphere is connected to the main induction pipe instead ; a vacuum servo 47 is thus actuated and shifts the arm 45 to the low-gear position. At the same time a vacuum servo 58, connected by branch 57 to pipe 51, draws down the rod 61 against its spring and releases the lock on the shaft 37 so that the driver can rotate this shaft to close the ignition switch and engage the main clutch of the auxiliary engine, which is then started by means of a starter button on the handle 37. When the auxiliary engine has started the clutch on the front axle 13 is engaged by means of a vacuum servo 31 connected by a pipe 33 to the induction pipe of the auxiliary engine. In a modification, Fig. 7 (not shown), the locking rod 61 is operated by a solenoid energised by a switch controlled by a vacuum servo connected to the pipe 51 so that the switch is closed when there is a vacuum in the pipe. U.S.A. Specification 2,183,667 is referred to.
