Title: Improvements in and relating to shoe sealing methods and devices for rotary type regenerative heat exchangers
IPC: F28D19/04
Filed: 1950-05-03
Abstract: 709,332. Regenerative heat-exchangers. PARSONS & CO., Ltd., C. A., and KOLB, P. April 23, 1951 [May 3, 1950], No. 10968/50. Class 64(1) In a sealing arrangement for a rotary matrix type regenerative heat-exchanger employing either a disc or drum type rotor, in which sealing shoes slidable on the surface of the rotor are employed to seal the hot and cold gas sides of the apparatus from each other, the sealing shoes are pressure balanced by causing gas contained in that portion of the rotor passing through the seal to act both on the front or sealing surface of the shoes and also on back of the sealing shoes so that the gas pressure on the shoe faces in contact with the rotor is continuously counterbalanced by the pressure exerted by the gas on the backs of the shoes whereby the force required to maintain the shoes in sealing contact with the surface of the rotor is independent of fluctuations of gas pressure on the faces of the shoes during operation of the rotor. The apparatus shown includes a drum-type rotor a of the kind described in Specification 655,313 and divided by radial webs n into compartments each containing matrix material o through which the hot and cold gases are caused to pass in a radial direction. Sealing shoes u are maintained in sliding contact with the inner and outer cylindrical walls l, m of the rotor by plungers Z which are acted upon by springs 1 and are carried in guides forming part of the structure of the casing 3. Projections v on the sealing shoes on the side thereof opposite their rubbing surfaces engage in recesses W formed in parts' X of the casing structure. Holes 5 formed in the shoes extend from their rubbing surfaces to the spaces between the projections v so that gas pressure in the particular rotor compartment passing under the shoe is transmitted also to the surface of the shoe opposite its sealing surface. The effective sealing pressure is thus applied only by the springs 1 and is independent of the gas pressure in the rotor compartment passing through the seal.

Title: Improvements in transforming alternating rectilinear movement into continuous rotary movement
IPC: F16H21/30
Filed: 1938-04-11
Abstract: 502,989. Driving - gear. LATH,. A. April 11, 1938, No. 11023. [Class 7 (ii)] [Also in Group XXIV] Consists in means for converting the reciprocating motion of a piston into rotary motion of a shaft. As applied to an internal-combustion engine, a piston 4 has attached thereto two rods 5 between which is fixed a rack 22 adapted to gear with 'a toothed sector 23 keyed to the main engine shaft 24 which is connected by gearing 25 ...27 to an auxiliary shaft 16. This shaft has crank arms 14, 15 to which are pivoted, at 12, 13, other arms 10, 11 integral with a crank pin 9 connected by a rod 7 to the rods 5, the point of connection being guided by a cross-head 28 and slide 29. Pins 17, 19 extending from the crank arms 10, 14 form pivots for a plate 18 of triangular form the other apex carrying a roller 20 which runs in a fixed cam groove 21. The number of teeth in the sector 23 is such that the rack 22 is clear of the sector at the bottom of the stroke. When the piston 4 descends from the position in Fig. 1, the shaft 24 is rotated and this rotates the auxiliary shaft 16. Difference in speeds of the sector 23 and the crank pin.9 are provided for by the jointed crank arms, the plate 18 and the cam groove of predetermined form. When the piston reaches the bottom of its stroke, the rack is free of the sector and is moved up again by the shaft 16 and its associated linkwork. The sector 23 drives only during the working stroke, the other strokes being performed by the auxiliary shaft. The ratio of the wheels 25, 27 depends on the cycle of the engine. The sector 23 may have a set of diametrically opposed teeth which would act on the rack during the suction stroke.

Title: Improvements in or relating to card indexes
IPC: H04Q1/14
Filed: 1966-03-15
Abstract: 1,121,396. Card indexes. W. KOLLER. 15 March, 1966 [1 April, 1965], No. 11254/66. Heading B6E. In a card index consisting of a case with a drawer for index cards, and means for unlocking the drawer and releasing the index card selected by means of a key, a single operation of a selector key will unlock the drawer and select the desired card, and that card will be freely available for writing on, or withdrawal from the drawer. The card index comprises a case 4, a drawer 2 open at the rear and acted upon by a push spring 12, and the index cards 1 are of resiliently elastic material. The cards (Fig. 1) have aligned side recesses (15) near the front for retention by pins 6 on the base of the drawer, and the front edges of the cards have selector recesses (20). The base of the case 4 has two cams (5) which protrude through two parallel longitudinal slots 3 in the drawer 2. Mounted in slots in the top of the case are several selector keys 7, each having a pin 8 and shoulders 19, and urged upwardly by a spring 13. The drawer is retained in the closed condition by a pawl 10 which engages, by the action of a spring 17, a recess 11 in the side of the drawer, the pawl being slidably mounted in control rail 9 which can be pivoted when any key 7 is depressed, to release the pawl 10, and allow the spring 12 to open the drawer. With the drawer closed (Fig. 2), the cams 5 urge the front ends of the resilient index cards upwardly adjacent the pins 8 on the selector keys 7. If a key 7 is now depressed, its pin 8 presses on the appropriate index card within the recesses (20), and bends that card, and any others below that card, so that the pins 6 engage the side recesses (15) and retain the cards. During the further downward movement of the key 7, the control rail 9 is tipped to release the drawer 2, and the latter than moves outwardly of the case 4 (Fig. 3). The desired index card 1 is thus fully exposed for writing on, or for complete withdrawal. In a modification (Figs. 5 and 6), the pins (8) of the keys 7 are hookshaped and arcuate at their free ends (25). The case 4 for the drawer 2 can be the base fitting of a telephone, with a pedestal surface and base fillets.
