Patent GB-1536250-A (GB)
Title: Regenerative heat exchanger
IPC: F28D19/04
Filed: 1977-04-05
Abstract: The regenerative heat exchanger has a rotor with a storage body (19) which consists at least essentially of corrugated tape layers having transverse grooves (24', 24'') reaching from end face to end face. Flowing through the storage body as the rotor rotates are different, simultaneously present gas streams between which the storage body effects the exchange of sensible heat and/or latent heat. In order to improve the heat exchange or to reduce the storage body for a given heat-exchanging capacity, the transverse grooves (24', 24'') of adjacent corrugated tape layers are directed obliquely relative to one another, and at least some of the transverse grooves of each corrugated tape layer are open to transverse grooves of adjacent corrugated tape layers which are likewise open with respect to them. <IMAGE>

Abstract: 1,186,684. Turning inside out. HALL TEXTILES (MANSFIELD) Ltd. 1 April. 1968 [30 March, 1967], No. 14442/67. Heading D1X. [Also in Division A3] The apparatus for use in examining and turning garments of Specification 1144639 has an arm 9 pivotally mounted on the upper end of each tube 1 and biassed to the upwardly inclined position shown by means of a spring (14) secured to the lower end of the tube and to a cord (15) connected to the arm 9, Fig. 2 not shown. Extensions (13) of transparent plastics material are adjustably mounted on the arm 9 by means of a bolt (12), Fig. 2. In use, a garment such as a shirt S is drawn on to the tubes with the arms 9 in the position shown to support the shoulders and neck as in wear, lights within covers 4 on the tubes are switched on and the platform 2 supporting the tubes is rotated to allow examination of the shirt body. Then the shirt is drawn further on to the tubes so that the latter project into the sleeves, the arms 9 being pushed down, against the action of the springs (14), within the covers 4.

Title: Typewriting machine
IPC: B41J23/06
Filed: 1947-05-30
Abstract: 635,916. Typewriters. UNDERWOOD CORPORATION. May 30, 1947, No. 14445. Convention date, Dec. 3; 1938. [Class 100 (iv)] In a power-driven typewriter of the kind having a semi-circular array of type levers which are spring-urged towards inoperative positions and are connected to their operating levers at graded lengths from the pivots of said levers and having selectively operated pusher actuators arranged in a straight row adjacent a continuously-operating power source associated with the type-levers, the actuators 34 are normally spring-held against a stationary abutment 35 free from the power source 38 and have vertical arms 28 pivoted thereto which are in individually formed rolling contact with their associated type-bar operating levers 21 to transmit, when operated, equal power movements to the type bars. The actuators 34 are selected by the key levers 41 by the engagement of a hooked member 69 with a projection 52 on the actuators 34 and upon depression a pawl 37 on the end of actuator 34, held by gravity in an anticlockwise direction, is engaged by the power drive 38. A spring 36 ensures that there is no movement of actuator 34 until good contact is made between parts 37, 38 and until the pawl 37 is halted by a stop 56. The spring also causes immediate return of the actuator to normal position in advance of and independently of the return of the type-bars 11 and operating lever 21 to normal positions. The levers 21 are mounted on a straight axis 23 and connected to the type-lever 11 by connecting- rods 19, and the points of connection 26 at graded lengths from the axis 23 lie on a vertical arc in front of an arc along which the links 19 are connected to the type-bars 11. Each lever 21 has a differently-shaped contacting surface 68 so that the action of the parts 28, 34 thereon in combination with the varying leverages of levers 21 ensures that equal power is given to the typebars. Disengagement of the actuators 34 from the power drive 38 is effected by surfaces 58 engaging a head 59 of individually adjustable screws mounted in a universal bar 60. Bar 60 is carried on pivoting arms 61, 62 so that the power imparted to all actuators 34 can be simultaneously adjusted by movement of the arms about a pivot 23 against the tension of a spring 66 and adjustably positioned by the rotation of an eccentric 64 attached to a dial control 65. Ink-ribbon feeds and vibrator mechanism. Extensions 75 of the levers 21 are of varying length to compensate for their differing angular movements and impart a constant movement to the universal bar 74 connected to the ribbon mechanism. Tongues 72 on the bar 74 are bendable to compensate for small differences in the throw of the levers 75.

Wt. of 400-3000 and containing 33-95 mole percentage of (b), and wherein the polymer also contains a telogen component. Printing inks are produced from the composition by addition of a pigment which is dispersed throughout the polymer solution. Examples of (a) are acrylic acid, methacrylic acid, maleic acid, maleic anhydride or half esters of maleic acid with C 1-12  monohydric alcohols. Examples of (b) are ethylene, propylene, butylene, octene, styrene and its derivatives, derivatives of acrylic or methacrylic acid such as esters and nitriles, vinyl pyridine, vinyl pyrrolidone, allyl esters and allyl ethers. The polymers are preferably derived from telomers of styrene/maleic anhydride, octene/maleic anhydride, styrene/ acrylic acid, or styrene/vinyl toluene/maleic anhydride. Telomerizing agents may be used, such as cumene, cymene, p-xylene, toluene, benzene, chloroform, methyl ethyl ketone, diisobutyl ketone or mixtures thereof. The solution may be an up to 50% by weight solution of the copolymer, but concentrations of 20-50% are preferred. A proportion of the toluene may be replaced by benzene, xylene or a mixture thereof. In the examples, the polymer solutions are produced by solution polymerization in toluene by standard methods and the resulting solutions pigmented. The inks formed were coated on to paper. The polymers produced may contain, for example, 0À08 to 0À9 carboxyl groups per 100 units of molecular weight.

Abstract: 415,539. Hinges. TALBOYS MANUFACTURING CO., Ltd., and CARROLL, A., Tame Road, Witton, Birmingham. May 20, 1933, No. 14601. [Class 65 (ii).] In a hinge for the leg of a folding table, having a hand-released catch associated with the leg and engaging a fixed part of the table to hold the leg in the operative position, the catch is provided with an inclined or wedge surface which tends, as the catch is forced into engagement with the fixed part by a spring, to draw the leg up against its stop and take up any wear on the pivot. In the form shown, the leg c is formed of sheet metal, and is attached by a pivot pin e to a fitting d of substantially U -section secured inside the corner of the table top flange b. A plate f secured to the leg abuts against flanges of the member d to limit motion in the unfolding direction, and a catch k, pivoted on the leg and pressed by a leaf spring p, engages under the flanges to lock the leg in position, inclined engaging edges n of the catch tending to force the leg hard against its stop. The opposite leg has its pivot offset, to allow it to fold underneath the leg shown.
