Patent GB-185076-A (GB)
Abstract: 185,076. Haddan, A. J. H., (National Cash Register Co.). Feb. 26, 1921. Transfer mechanism.-In a multiple-totalizer machine such as that described in Specification 184,824, wherein an assemblage of totalizers is actuated by reciprocating frames each provided with a corresponding number of main racks 118, the transfer operation is effected by supplemental racks 302 pivoted upon the frame and becoming, at transfer, continuations of their contiguous main racks. The supplemental racks are pivotally supported at 303 upon the actuating frame formed by a pair of spaced plates and are provided with a pin 304 movable in an elongated aperture 305 in one of the plates. The pin carries a bell-crank lever 306 the long arm of which has an L-shaped slot 307 engaging a pin 308 on the frame plate. At transfer, the long pin 320, Fig. 4, on the numeral element rocks a lever 323 so as to free one of its two steps 325 from a spring- controlled trip lever 314 pivoted on the machine framework. The trip lever thereupon engages the other step 326, and one of its arms namely 316 is thus placed out of the path of the short arm 309 of the corresponding bell-crank lever 306 appertaining to the next higher wheel. Consequently this lever and therefore also its supplemental rack are free to travel with the actuating-frame to the extreme position and the rack thus forms an extension of the main rack so as to give an extra movement to the higher wheel. If a trip lever is not tripped, the pin 316 discharges its normal function of obstructing the arm 309 and so preventing the supplemental rack from completing its movement with the actuating-frame. When the lever 306 is rocked by meeting the pin 316, the pin 308 is received by the horizontal portion of the L-slot 307, and a notch 312 in the lever falls into engagement with a fixed tooth further to hold the lever. The trip levers that have been tripped during an operation are restored at the beginning of the next operation by means of a bar 330 provided with lugs 333 to engage the trip levers and shift their arms 318 from step 326 back to step 325. This bar is moved at the end of the forward movement of the differential mechanism by means of an arm 336. Specification 185,075 also is referred to.

Abstract: 1,219,933. Transistor amplifier circuits. SIEMENS A.G. 19 April, 1968 [20 April, 1967; 26 Jan., 1968], No. 18514/68. Heading H3T. An active filter comprises an amplifier having a push-pull input or output with a frequency selective bridge feedback network formed in part by the input or output impedance of the amplifier, the impedances of the bridge elements being such that a pair of zero points are obtained in the transmission characteristic of the filter. In one embodiment, Fig. 2, the feedback bridge I comprises the push-pull output impedance of the amplifier, a series CR arm, and a parallel CR arm. A further network II is also provided to give pole points in the characteristic. In an alternative arrangement, Fig. 7, an additional impedance is included between the two bridge arms at x, y and either a high or a low-pass characteristic may be obtained depending on whether y is connected back to the input, and x to the output or vice versa. Low-pass, high-pass and band-pass filters for push-pull inputs and single-ended outputs are also described, Figs. 10, 11, 12 (not shown).

Abstract: An organic compound, for example methylene chloride, is recovered from a mixture of air and the vapour of the compound in which the concentration of the vapour is greater than 40 grams per cubic metre by a process comprising passing the mixture to a series of activated carbon adsorption units one or more or which has been previously flushed with steam, and controlling the temperature of the air-vapour mixture in the ducting between the operating units so that the heat introduced into the steam-flushed unit or units together with the heat of adsorption of the compound in that unit or units is just sufficient to drive adsorbed water from the activated carbon in that unit or units.

Abstract: 530,589. Slicing-machines. BERKEL & PARNALL'S SLICING MACHINE MANUFACTURING CO., Ltd. (Maatschappij van Berkel's Patent N.V.). June 27, 1939, No. 18633. [Class 28 (ii)] In a slicing-machine of the reciprocating substance-carrier type, the slice-thickness gauge is supported and guided for slice-thickness adjustment on the bracket in which the slicing knife is journalled, thus leaving the space behind the knife, bracket and gauge free from obstruction by gauge supporting parts. The usual inclined disc knife 10 is rotated from an electric motor 13, and is journalled in a bracket 11, which is provided with fixed inclined supports and guides 16, 17 engaged respectively by bearing members 18, 19 on the gauge plate 12, the guide 17 having a screwed portion 17A, Fig. 2, which is engaged by the screwed end of a rod 21 extending through a sleeve 20 on the gauge plate, whereby when a knob 22 on the rod 21 is turned, the plate 12 is displaced away from the slicing plane to increase the slice thickness, and also away from the knife to leave a greater space for the passage of the thicker slices. In order to enable the gauge plate 12 to be swung aside for cleaning, the range of adjustment by the knob 22 is sufficient for the bearing 18 to leave the top guide 16, so that the plate 12 can be swung about the bottom guide 17 into an inoperative position. A slice receiver 15 is pivoted at 23 to a sleeve 24 on the reciprocating support 8 of the substance-carrier 7, so as to be reciprocated with the latter, and is movable angularly step by step to make room for successive slices by means of pawl-and-ratchet mechanism 30 operated at the end of each return stroke of the support 8 and applied to a screw 27 operating a nut 26 connected by a link 25 to the receiver 15.

Abstract: 130,601. Renkin, W. O. July 29, 1918, [Convention date]. Apparatus fitted to transporting-apparatus. - Relates to a pneumatic conveyer system by which any desired weight of powdered coal, &c. or liquid is transferred from a supply tank to any one of a series of storage bins. The supply tank 1 is mounted on the platform of a weighing-machine 2 and the material is discharged through the pipe 5 by actuating the lever 3 and compressed air valve 4 as described in Specification 122,836. The material passes from the pipe 5 through a switch valve 11 and branch pipe 12 to a pin 10 from which, in the case of coal, it passes to the furnaces through controllers 6 as described in Specification 121,135, [Class 51 (ii), Furnaces and kilns for applying &c.]. An electric circuit 33 extending from the bin to a position near the tank 1 includes a switch 35 and is controlled by a rotary arm 13 carrying contacts. The operator causes material to be discharged until the weighing-machine 2 indicates that the requirements of the nearest bin have been satisfied. The switch 35 for this bin is then opened, and causes the rotation of the valve 11 to open the pipe 5 and to close the branch 12. The operation is repeated for each bin in order along the pipe 5.
