Filed: 1971-10-12
Abstract: 1364557 Space heaters W W MUNZ 12 Oct 1971 [13 Oct 1970] 47486/71 Heading F4S A space heating radiator unit consists of a plurality of hollow-plate elements carrying a heating medium (e.g. hot water) and disposed in a staggered disposition with a partial overlap of adjacent elements when viewed from the front of the unit; and fluid connections being provided between the elements at the zones where they overlap. The hollow-plate elements may be cast in aluminium or grey cast-iron, or they may comprise each a pair of plates welded together at their edges. The front of the assembly may be painted or alternatively decoratively covered with metal, wood or plastics film or with a stretchable fabric. A great variety of shapes is described for the hollow elements. For example they may be substantially flat or of bowed form (Figs. 14-16) and they may be circular Figs. 22, 23 or 40, square (e.g. Figs. 18, 19), rectangular (e.g. Fig. 25), trianglar (e.g. Figs, 36, 37, 39) or other polygonal shape, e.g. diamond, hexagonal or trapezoidal, in outline. Each plate has either three or four connection points arranged respectively in triangular or square array and this facilitates arranging the assembly in otherwise awkward situations, e.g. around a window (Fig. 3) or on a stairway (Fig. 4). The assembly may include hollow elements which enable the radiator to encircle or lie within a column (Fig. 16a) or to cover an external or internal corner of a building structure (Figs. 16b, 16c). Figs. 1 and 2 slow a radiator unit arranged in a wall recess N. The unit consists of two rows of identical hollow-plate elements 61 each with four connection points viz. A1-A4, and two half-elements 65 each with two such connection points. The heating medium enters the assembly via a pipe 66 and discharges therefrom via a pipe 68. At the interconnection points, e.g. A, Fig. 1, the adjacent sections may be either welded together or interconnected by screwed nipples, several forms of which are illustrated (Figs. 44-51). In some arrangements, convection air heating passages are formed by the elements. KA denotes such passages in Fig. 27.

Several impregnation heating cycles are necessary to introduce sufficient oxide. The structure so formed may be used with a nickel anode as a hydrogen/air cell.
Patent GB-482291-A (GB)
Abstract: 482,291. Cash registers. NATIONAL CASH REGISTER CO., Ltd. (National Cash Register Co.) Sept. 25, 1936, No. 26079. [Class 106 (i)] [Also in Group XVI] Printing on inserted material.-A cash register or similar accounting- machine in which during a machine operation a record strip and an inserted slip are impressed by means of a single set of type-wheels and a single hammer, is provided with means to prevent the insertion of a slip until after an impression has been made on the record strip. The slip is inserted in a guideway 7 and, after a hammer 2 has impressed a record strip 3 against a set of type-wheels 1, is moved to printing position by two pairs of feed rollers 8, 9 and 12, 13. The lower rollers 8, 12 are geared together and driven by a mutilated gear 22 on a shaft 20 that receives a complete clockwise and counterclockwise rotation at each operation, the arrangement being such that, after impression, the slip is ejected from the machine. To allow the slip to be inserted into the guideway, the roller 13 is raised out of contact with the roller 12 while the machine is at rest, being mounted for this purpose on arms 16 controlled by a cam 44 through a pitman 29. The rollers 8, 9 are, however, always in contact to prevent manual propulsion of the slip to printing position. To disable the slip feed or enable two impressions to be made on the slip, an assembly of gears 34 on the spindle of roller 12 is moved axially one or two steps by a cam 47 controlled by a handle 41, the assembly being thus moved out of mesh with gear 22 and into mesh with a locking disc or with a second gear on shaft 20, which second gear is adapted to give the rollers two feed movements followed by two ejecting movements. Instead of being adjusted by the handle 41, the cam 47 may be controlled by the transaction keys.

Abstract: 1,091,052. Change-speed epipcylic gear and control. JOHN M. PERKINS & SMITH Ltd. Jan. 20, 1965 [Dec. 9, 1963], No. 48424/63. Heading F2D. In a change-speed epicyclic gear, for power tools such as portable drills, a handle 30 extending radially and normally from the casing 29 of the gear is selectively rotatable about its own axis in opposite directions from a Neutral position to alternatively arrest two reaction members 22, 23 respectively connected to elements of the gearing so as to provide alternative output speeds and/or rotational directions. A member 33 secured, as by screws, on the casing 29 houses two pairs of balls 40 respec. tively aligned with the members 22, 23. The handle 30 is retained on a spindle portion 32 of the member 33 and has secured thereto a flange 41 having a pair of cam surfaces 42 engageable with the outer balls of the pairs of balls 40. Rollers 28 are housed in part cylindrical grooves in the peripheries of the members 22, 23, each groove being flanked on one side by a raised projection. The rollers are retained by peening over the groove edges or by washers or circlips. The handle 30 is rotationally positioned with respect to the member 33 by a means, not shown, comprising a spring loaded detent ball which is carried in the flange 41 and is engageable with three spaced recesses in the member 33. In the reversing gear shown, providing forward, and reverse at a higher speed than forward, planets 17 mounted on a carrier 14, 15 fast with the member 23 mesh a sun 12 fast on an input shaft 10 and a ring 19 fast with the member 22. Planets 18 mounted on a carrier 16 fast with an output shaft 11 mesh a ring 20 also fast with the member 22 and a sun 13 fast with the carrier 14, 15. The input shaft 10 engages or replaces a tool-carrying chuck and the output shaft 11 is screw-threaded to carry a chuck for a drill or tap. In operation, when the handle is rotated in one direction from Neutral, one pair of balls 40 is cammed into a position such that the inner ball engages one of the rollers 28 of the member 22 so as to hold the rings 19, 20 for reducedreduced Forward drive. On moving the handle in the other direction of rotation firstly the previously cammed balls are permitted to move outwardly, and then, on further handle rotation, the inner ball of the other pair is moved to arrest the member 23 to hold the carrier 14, 15 for reduced reverse-reduced Reverse drive. In one modification, an adjustably prestressed spring may be provided between the handle and a non-rotatable part associated therewith, so that when an obstruction is met when working the balls may ride over the rollers. In a further modification, the spring-loaded detent ball is dispensed with, the handle is spring loaded to Neutral, and the cam surfaces 42 have such inclination that on meeting an obstruction the handle will automatically be returned to Neutral when a predetermined reaction force is applied.
