Title: Improvements in or relating to absorption refrigerating apparatus
IPC: F25B15/10
Filed: 1937-08-19
Abstract: 501,399. Refrigerating. HOOVER, Ltd. Aug. 19, 1937, Nos. 22759, 22760, 22761, and 22762. Convention dates, Aug. 24, 1936, Aug. 26, 1936, Dec. 30, 1936, and Dec. 30, 1936. [Class 29] Absorption machines and systems.-In a machine of the kind employing an inert pressureequalizing gas such as air or nitrogen, a part of the inert gas is tapped off from the main stream and used to raise liquid in the system. In a system of the kind described in Specification 501,398 and employing two evaporators and a twin-gas lift pump for supplying liquid refrigerant to the evaporators, the tapped-off gas is employed to operate the pump. In a modification, the inert gas tapped from the outlet F<2> of the circulating fan F is employed to force liquid refrigerant up the pipe J to the top of the evaporator E. In this case, the bottom of the pipe J is connected through a bend C<1> with the condenser C which is provided with an inert gas vent pipe C<2> and an overflow pipe C<3> connected to the strong liquor return pipe H<1> between the reservoir H and the generator B. The partial evaporation taking place in the pipe J precools the liquid passing to the evaporator. In another arrangement, a part of the inert gas passing into the pipe K, Fig. 3, connected to the liquid refrigerant lift pipe J flows through the pipe M and lifts weak liquor from the generator B up the pipe B<3> into the absorber A. Thus by controlling the speed of the gas circulating fans F the rates of circulation of all the fluids in the system are regulated.

Title: Improvements in apparatus for pressing rubber articles
Filed: 1946-07-31
Abstract: 603,177. Making rubber articles. UNITED STATES RUBBER CO. July 31, 1946, No. 22793.. Convention date, Oct., 10, 1945. [Classes 17(i) and 141] [Also in Group V] One or more carriages, each provided with means for applying pressure to the seams of component parts of rubber footwear as these are assembled on lasts carried by a conveyer are moved a short distance in time relation to the conveyer so as to press the seams and then to be returned ready to operate on the succeeding shoe assembly on the conveyer. Gloves and other rubber articles may also be made in this manner. Fig. 1 shows the general arrangement of conveyer 12 with the direction of motion indicated by arrows, and Fig. 5 shows a sectional view on line 5-5, Fig. 1. Shoe parts are assembled on lasts L removably mounted on pivoted jacks J supported on arms 14 rigidly secured to trucks 15 attached to the chain of the conveyer 12. Rollers 16 on the trucks engage supporting bars 17, supported on legs 11. Three stations equipped with means to exert pressure on different portions of the shoe are shown in Fig. 1 spaced along the assembly table 10. At the first, strong yielding pressure is applied to the opposite sides; at the second, the front and back are pressed; and at the third (shown in Fig. 5,) pressure is applied upon the sole and heel to bond them to the upper. The pressing apparatus is in each case mounted on a travelling carriage 20 wheels 21 of which rest on spaced rails 22 on a frame. Upper rails 25 prevent the carriage lifting. Compressed air may be supplied through a four-way valve 35 to opposite sides of a piston 29 by pipes 27, 28 first'to move the carriage forwards at a speed slightly in excess of that of the chain 12 so as to cause a dog 30 pivoted on a support 31 projecting downwards from the carriage to abut against the rear face of a jack-supporters arm 14 to synchronize the travel of carriage and shoe. A weight 33 normally holds the upper end of dog 30 against a stop 34 on support 31, and, during return travel of the carriage, the dog will tilt and pass over the next advancing arm 14. The supply of compressed air to the opposite ends of the cylinder 24 is timed in relation to the conveyer movement by a rocking lever 39 secured to the stem of the valve 35 and positioned to hang down in the path of the arms 14, so that, as the jack J carried thereby advances, it strikes the lever and holds it elevated until the arm travels beyond reach of the lever, which then drops by gravity to reverse the operation of the valve 35. Downward movement of the arm 39 is arrested by a stop. Pressure is applied to the pressure means on each carriage by fluid-pressure controlled through a valve stem 58 of a valve 57 on the carriage 20 and operated by a weighted lever 59 actuated by the back and forth movement of the carriage. After the assembly operations are completed, the last, with the shoe, thereon, is removed from the conveyer and placed in a vulcanizer.

Title: Improvements in accelerators for rubber vulcanization
IPC: C08K5/29
Filed: 1925-09-17
Abstract: 263,517. Marks, E. C. R., (Du Pont de Nemours &Co., E. I.). Sept. 17, 1925. Samples furnished. Aldehyde-amine condensation products.-Materials for use as accelerators for rubber vulcanization are produced by the interaction of formaldehyde with the condensation product of an amine, for example an aromatic amine, such as aniline; and an aldehyde, for example an aliphatic aldehyde having a plurality of carbon atoms such as acetaldehyde. The materials may be heated, to a temperature above 85‹ C. but preferably below 125‹ C. during the reaction. In the example described, acetaldehyde is condensed with aniline, the temperature being allowed to rise slowly to 70‹ C. by the heat of reaction. The mixture is then kept at 80-85‹ C. for about two hours to complete the reaction. Formaldehyde solution is next added, the temperature rising about 10‹ C. and being then maintained at 85-125‹ C., with stirring, for two hours. Vacuum is now applied to withdraw water from the molten resin produced, which is then drawn off, allowed to cool, and ground to prepare it for use in vulcanization. Tables are given in the Specification showing the effect on the finished rubber of the use of this product during vulcanization. Open chain aldehydes other than acetildehyde may be used, and also other aromatic amines, such as the toluidines. naphthylamines, and phenylene-diamines. Preferably, from one third to one molecular proportion of formaldehyde is used to each molecular proportion of amine. The Specification adverts to the production of condensation products of acetaldehyde and aniline, references to literature being supplied, and of propionaldehyde, butyraldehyde and other aldehydes with aniline, and of these aldehydes with other aromatic amines, such as the toluidines. Reference has been directed by the Comptroller to Specification 251,005.

Title: Television apparatus
Inventor: LEGLER ERNST
IPC: H04N9/76
Filed: 1970-05-13
Abstract: 1,262,260. Television. FERNSEH G.m.b.H. 13 May, 1970 [16 May, 1969], No. 23233/70. Heading H4F. Relates to an arrangement for mixing television signals (in particular colour television signals) whose individual levels may be adjusted between zero and a maximum value to produce a composite television signal having constant amplitude synchronizing signals (including the colour bursts) and picture components of amplitude limited to a normal white value. In a first embodiment, Fig. 1, three synchronous colour television signals are fed via respective variable amplifiers 12, 22, 32 to a device 8 which combines the three signals and separates the resulting signal into the synchronizing information which is fed to a saturating amplifier 1, and picture information which is fed to a saturating amplifier 2. These saturating amplifiers have response thresholds adjusted at the nominal value of the synchronizing information and the nominal white value of the picture information respectively, saturation control being effected to maintain the outputs constant only when the output levels reach the nominal values. To ensure that the sync. signals always have a constant amplitude i.e. always reach their nominal value the sync. signals delivered from saturating amplifier 1 are supplemented by sync. signals from a further saturating amplifier 5 whose output is controlled (or blocked) by the sum signal derived by adding stage 6. The composite signal is formed at the output of adding stage 3. Amplifier 2 may have in addition to a response threshold for the total picture information of a colour television signal, a preferably adjustable response threshold for the luminance signal, the saturation control being effected when either signal reaches its threshold (Fig. 2, not shown). In a second embodiment, Fig. 3, the television signals are split into their separate picture information components and sync. information components prior to adjustment of their levels. The picture information components are fed to respective adjustable amplifiers 14, 24, and 34 whose outputs are connected mutually in parallel (not shown) and taken to the input of a saturating amplifier 2. The sync. information components are fed to fixed amplifiers 15, 25, 35 (whose amplification factors are preferably equal to the maximum amplification factor of the amplifiers 14, 24 and 34) whose outputs are likewise connected in parallel with each other to the input of a saturating amplifier 1. If any of the amplifiers 14, 24, 34 are set at zero the corresponding sync. information is blocked, and when all the amplifiers are in their zero setting a separate sync. e.g. colour bursts, is supplied from terminal 7 to amplifier 1. If any of the television signals are non-synchronous they are blocked by switches 11, 21 or 31.
