Abstract: 352,728. Planing and shaping. CLOWES, S., 1, Horwood Crescent, Withing- ton, Manchester, STOTT, S. H., Milford, Woodville Grove, South Reddish, and CRAVEN BROS. (MANCHESTER), Ltd., Vauxhall Works, Reddish, both near Stockport. July 7, 1930, No. 20499. [Class 83 (iii).] In planing, shaping, and like machines, the tool is relieved on the idle stroke by an electromagnet mounted on the clapper carrier which actuates a lever pivoted a bout the fulcrum of the clapper. A clapper f pivoting about a pin e carries an adjustable stud h on which bears a lever g actuated by an electromagnet a energized by switch gear at the end of a reciprocation to relieve the tool. According to the Provisional Specification a similar mechanism may turn the clapper box through 180‹ so that a single tool cuts in each direction of the stroke, or may rock a double cutter to bring each cutting edge alternately into operation, and mechanism other than that described may be operated by an electromagnet to move the tool.

Patent GB-207824-A (GB)
Abstract: 207,824. Shipley, B. M. Dec. 2, 1922, [Convention date]. Cash registers with operating-means. - The machine has means for registering, indicating and printing the quantities of commodities sold in terms of non-decimal denominations, as well as the usual information such as monetary amounts, and the characteristics denoting the cashier, the salesman and the class of goods sold. The invention is described as applied to a machine of the kind described in Specification 8119/15 but adapted for use at petrol filling stations, the quantities sold being registered in terms of gallons and pints. Moreover, the keyboard is equipped with a field of keys for use in printing, say, the number of the customer's car licence. Transfer mechanism.-This is substantially the same as that described in Specification 100,569 but having the following mechanism applied to the pints denomination. The pints totalizer pinion 150 is of standard form having ten teeth but three of these are lengthened instead of one. When the pinion passes from 7 to 8 transfer to the gallons pinion is initiated and simultaneously parts are set to effect, when the movement occurs, an advance of the pints pinion through 8 and 9 to zero. Of the three long teeth shown in Figs. 5 and 7, 151 is the transfer tooth and when this comes round it rocks through arm 162 an arm 158 to disengage its pin 159 from a notch in the spring-controlled lever 155. The. square pin 156 on lever 154 carried by the transfer-effecting segment 153 pivoted on the differential actuator 63 is thus freed from obstruction bv the lever 155 and consequently the segment 153 travels with the actuator through the necessary two steps beyond zero and moves the pinion to 0. The arm 162 is extended to engage a pin 164 on the neighbouring arm 165 corresponding with arm 162 and appertaining to the gallons pinion so that transfer to this pinion occurs in the usual manner.

Medicines for internal use ; medicinal powders for external use; coatings for medicines; inhalations; deodorants and antiseptics. - Activated carbon for sanitary, medicinal, and therapeutic purposes is prepared from vegetable matter, with or without the addition of inorganic materials prior to or during preparation, by carbonizing the raw material or using carbonized material, and activating the carbonized material by an activating gas while it is kept in a state of suspension or movement by a. blast of gas or by mechanical means, and purifying the activated material according to the process of the parent Specification. When the activated carbon is prepared as described in Specifications 198,328, 206,862, 213,935, or 239,694, fall in Class 90, Non-metallic elements], the treatment with the alkali may be dispensed with. For internal use., the carbon is ground very finely except when taken especially for gas absorption. It may be taken with water of with syrup, or may be made up into pills or tablets with a binder, such as cane, lactic, or invert sugar, or glucose, which is soluble in water, saliva, and gastric juice but is not absorbed bv the carbon. The use of gum, gelatine or the like is unnecessary in view of the fibrous nature of the carbon. The pills &c., may be coated with a palatable substance such as sugar, chocolate or a coffee preparation, an inner coating of a substance such as dextrine being provided to prevent access of the palatable materialto the carbon. In some cases the carbon mav be impregnated with alkalies, such as the carbonate, bicarbonate, or oxide of magnesium or calcium,. or with acids, salts, nitrogenous matter, alkaloids or crystalloids. The carbon may also be used as a powder for inhalation, and can be sprinkled on external wounds as a curative, deodorant, or disinfectant agent.

IPC: B64B1/58
Filed: 1923-08-21
Abstract: 202,657. Luftschiffbau Zeppelin Ges. Aug. 21, 1922, [Convention date]. Aerostats.-The loose netting for preventing the bulging of. the gas cells in rigid airships has its individual strands secured only to the junction points of the main framework irrespective of the number of bays crossed so as to avoid lateral loads upon the main members. Fig. 3 shows two wires g, h extending over two bays of the main framework and secured at the outer corners, the wires being loosely guided where they cross the intermediate member by a fitting i. The fittings i may be arranged so that the wires are displaced from their true diagonal direction in order to enable more wires to be placed across each bay. Where the wires do not cross an intermediate member they may be arranged as shown in Fig. 2 where wires c, d, c<1>, d' are connected together at two crossing points f, f<1>. In order that the amount of bulging shall be predetermined the various wires are passed over an adjustable bolt q, Fig. 6, carried by a beam p temporarily laid across from corner to corner of the framework, the bolt q being pressed upwards by a spring which becomes fully compressed when the wire c is correctly tensioned.

Abstract: 1,157,408. Ice-making. GENERAL ELEC TRIC CO. 8 May, 1968 [15 May, 1967]. No 21699/68. Heading F4H. Ice-making apparatus comprises a mould cavity 3, a pad 6 for raising an ice-block from the mould, and a sweep member 15 which is movable about a pivot 17 from a first position (shown in full lines) at one side of the mould to a second position (shown in dotted lines, Fig. 2) in which it has dislodged the raised ice-block, the initial part of said movement serving to store energy in a spring 40 and the energy being released during the remainder of the movement so as to increase the speed of the sweep 15. The ice block is thus projected further into a collecting bin arranged below and to one side of the mould. One end of the spring 40 is secured to a fixed projection 41 and the other to one end of a link 43 pivoted at 45 to an arm 44 of the sweep 15. The spring is extended during movement of the sweep until pivot 45 moves over-centre with respect to the pivot 17 of the sweep, the stored energy being thereafter released. The sweep is moved by a yoke 30 (Fig. 3) which is disposed at the opposite end of the sweep to spring 40, the yoke having a first arm 32 which effects the initial part of the movement of the sweep from its first position and a second arm 36 which acts as a stop for the sweep and, upon reversal of the movement of the yoke, returns the sweep from its second to its first position. A feeler arm discontinues operation of the apparatus when the bin is full.
