Abstract: 448,784. Cushions. TALALAY, J. A., 5, St. Minver Road, Bedford. Dec. 12, 1934, No. 35728. [Class 52 (iv)] [See also Group V] Rubber articles, e.g. upholstery pads, having interior rubber supporting means for some or all of the outer walls, are made by building up the internal and external structure by assembling shaped rubber parts, placing a bonding medium of vulcanizable, preferably spongy, rubber between those adjacent surfaces which are to be joined together, and vulcanizing, either free or in a mould. The bonding medium may be a strip or plate of rubber, preferably spongy, or a mass of spongy rubber in fluid form. As shown in Fig. 1, the component parts of a pad consist of a top 1, four sides 2 and a looped internal supporting member 3. A thin strip 5, Fig. 3, of unvulcanized sponge rubber is inserted between some or all of the contacting surfaces of the looped member and, when the sides and top are placed in position, at those places where it is desired to have a secure join. The assembly is then vulcanized in a mould. The looped supporting member may be formed on formers 7, Fig. 4, and instead of the strips 4, fluid masses 6 of vulcanizable sponge composition may be introduced between adjacent surfaces. In the car seat shown in Fig. 7, the support is built up of bars 9 stacked crisscross fashion, a layer of vulcanizable sponge rubber is inserted between the places of contact and also where the outer cover 11 contacts with the support and the whole is vulcanized in a mould. Before vulcanization, the assembly is only roughly the shape desired but conforms to the shape of the mould during the curing. Parts of the support may be perforated and the perforation covered on both sides with rubber plates to form air cells, and sponge rubber composition may be inserted at places to ensure that the article swells to fill the mould. A bottom plate may be provided so that the pad forms a pneumatic cushion. Specifications 376,291 and 403,175 are referred to.

Filed: 1955-12-16
Abstract: 817,958. Transistor amplifying circuits. GENERAL ELECTRIC CO. Dec. 16, 1955 [Dec. 22, 1954], No. 36123/55. Class 40 (6). In a temperature stabilized common emitter amplifier, a resistor 17 is connected between the base and the junction of two resistors 18, 19 in the collector circuit. The resistor 18 may be decoupled to earth by a capacitor 22 and a further resistor 16 may be connected between base and emitter.

Title: Solvent recovery plant
Inventor: STEPHENS ALEXANDER
IPC: B01D53/06
Filed: 1961-10-13
Abstract: An apparatus for recovering solvents from gases or for drying air and other gases comprises an annular member (1) divided radially into compartments (17) and rotatable in an closed outer container (2), and two circumferential series of ports (19, 21) respectively in the inner and outer walls of the annular member and at opposite ends thereof, an inlet (40, 41, 46) and an outlet (79) for desorption medium, gas-tight members 149, 57 through which said inlet and outlet communicate respectively with a series of ports and one or more perforated boxes (23) containing absorbent in each of said compartments.  As illustrated in Figs. 1 and 3 (not shown) to which the above numerals relate, solvent-laden gas enters the outer casing 2 of the apparatus at 35 and passes through those of the ports 19 which are exposed, into compartments 17 each of which contains carbon adsorbent in a pair of boxes 23 having a perforated top and bottom and sealed into the compartment by means of flanges 22, 25.  The solvent-free air then passes into the interior of the drum through the corresponding ports 21 and is removed through an outlet in end-plate 14.  When a compartment reaches the position shown in the lower part of the drum, it is sealed from the gas in the outer casing by a shoe 56 and from the gas in the interior by shoe 49 having an opening 51.  Steam for removing adsorbed solvent is admitted at 40 to pipe 41 and passes via pipe 46 to shoe 49, and thence through opening 51 in the shoe and the corresponding port 21 into the compartment. After passing through the adsorbent, the steam and entrained solvent leave through the corresponding port 19 and opening 58 in shoe 56 and is withdrawn through pipe 78. The Specification also mentions the optional inclusion of filtering means in the base of the apparatus to remove dust particles from incoming gas and of a heater or cooler. Steam may be admitted continuously or intermittently at e.g. 60-100 p.s.i. The carbon may be dried with hot air in a similar manner to the steam treatment.

Abstract: 760,568. Variable pitch propellers. SPERRY CORPORATION. Dec. 21, 1954 [Jan. 18, 1954], No. 36931/54. Class 114. [Also in Group XXXVIII] In a variable-pitch propeller drive, the power for varying the pitch of the blades is supplied by a motor in the propeller shaft driven by the shaft. The shaft comprises interconnected sections 4, 5, 6, 7, 8, 9, 10, the latter being connected at 11 to the power plant. The blades 12 are connected via a pitch-setting linkage 2 to a rod 13 and piston 14 in a cylinder 15. The shaft section 9 comprises a sleeve 37 having an internal gear which meshes with pinions 30 and 32 secured to shafts 34, 35 mounted in the shaft section 8, the shafts 34, 35 having at their other end pinions 31, 33 meshing with a gear 36 fixed to a shaft 19 to which is secured an impeller 18, in a housing 17, the impeller and housing forming a pump 16 for supplying hydraulic fluid to the cylinder 15. Leakage of fluid is made up from an oil reservoir 23. The oil is supplied by gravity through passages 24 and 22<SP>1</SP> and lubricates the pitch setting mechanism and the actuating rod 13. The pump 16 is controlled by a variable speed drive 40 comprising a variable displacement hydraulic pump 41 driven by a belt 42 from the main drive shaft section 7, and connected, hydraulically to a variable speed hydraulic motor 44 connected by a pulley 45 and belt 46 to drive the sleeve 37. The displacement of the pump 41 is controlled by a push rod 47 connected to a central shaft 49 pivoted to a differential lever 72 which is pivoted at 76 to a ram piston 69<SP>1</SP> and at its end 75 to a ring 25 which is connected by rods 27 to the piston 14. In the Figure the drive is shown in its zero thrust position, i.e. the blades 12 are in neutral position, the pump 41 and motor 44 are revolving at such speeds that section 8 and sleeve 37 are at a 1 : 1 speed ratio, and the impeller 18 has no rotation relative to its housing. When the lever 50 is moved manually a mechanical connection 51 operates a potentiometer 52 in a bridge network 53 (see Group XXVIII) as a result of which solenoids 64, 65 are actuated to move a control valve 66 to permit hydraulic fluid to flow to move the ram 69<SP>1</SP>. The lever 72 is moved about its pivot 75 to move the control shaft 49 to alter the displacement of the pump 41 so that the section 8 and sleeve 37 no longer rotate at a 1 : 1 speed ratio. The impeller 18 therefore rotates relative to its housing and liquid is supplied to the cylinder 15 to move the piston 14 and thereby alter the pitch of the blades 12. As the piston 14 moves it carries the ring 25 with it, the lever 72 then pivoting about the point 76 and moving the control shaft 49 back to its initial position wherein the section 8 and sleeve 37 rotate at the same speed and the pump 16 is inoperative. Hence the blades 12 move to and remain at an angle of pitch corresponding to the position of the lever 50.
