Filed: 1935-10-08
Abstract: 462,991. Wireless receiving-apparatus. COLE, Ltd., E. K., and BRADFIELD, G. Oct. 8, 1935, No. 27703. [Class 40 (v)] [Also in Group XXXVI] A radio-receiver comprises a number of similar valve sockets each accommodating a valve base having at least seven pins, wherein some of the pins of some of the valves are dummies. The invention facilitates valve servicing and cheapens production by arranging a so-called " universal " valve of the kind shown in Fig. 1 to be inserted in a socket in any stage of the receiver, the socket connections being such as to enable the valve to assume the appropriate function of that stage. Thus, Fig. 2 shows a nine-pin socket which receives the valve of Fig. 1, the socket being so wired that the valve acts as a double-diode. The double-diode intended to be replaced in the socket of Fig. 2 by the valve of Fig. 1 when defective has a nine-pin base arranged and connected as in Fig. 3. A similar arrangement may be employed in case of a single diode stage, Figs. 4 and 5 (not shown), or for any other stage in a receiver. Thus, one spare valve of the Fig. 1 type will suffice as a replacement for any stage of the set.

Abstract: 928,344. Coin-freed apparatus. E. LIEBLER, H. LIEBLER, H. SEITZ, G. SEITZ, E. LIEGEL-SEITZ, R. LIEGEL-SEITZ, I. SEITZ, and H. SPENGLER, [trading as SEITZ AUTOMATENBAUGESELLSCHAFT]. Aug. 12, 1960 [Aug. 12, 1959], No. 27971/60. Class 27. Vending apparatus for selling at different prices from adjacent magazines has a common coin mechanism having a lever 12 pivoted on a bar 11 which is raised when a delivery means, such as a drawer, is operated; the lower end 32 of the lever 12 supports an inserted coin or coins so that the coin or the uppermost coin will engage under one of several pawls arranged one above the other and cause tilting of the lever 12 so that it clears a catch block 15. As shown in Fig. 5, two coin pockets 16, 18 for different coins are provided and each has a set of three pawls 19a, 19b, 19c or17a, 17b, 17c. The pawls pivot to their coin-engaging position by gravity and the two lower pawls in each pocket have tails projecting into recesses 21, 22 in operating bars 24, 20. Up to three lower-value coins can be inserted in one pocket and up to three higher-value coins in the other and transfer means (not shown) operates on withdrawal of a particular drawer to raise the bars 24, 20 to withdraw one or both of the lower pawls from one or both coin pockets to set the price required for release of the drawer. In their normal positions, the ends 32 of the levers 12 lie below a coin-return shoot 33 and the toes 26, 28 of spring-loaded blocking levers 31a, 31b block the shoot openings. In Figs. 5 and 8 is shown the case where two coins are required in the pocket 16 and one in the pocket 18, but an attempt is made to withdraw a drawer when only one coin has been inserted. The bar 24 for pocket 16 is raised by one unit of coin diameter as the drawer is pulled and moves the pawl 19a out of the pocket so that the lever 12 is lifted until it is in line with the return shoot. The toes 26, 28 are wihtdrawn from the return shoots as a pin 30 on the bar 11 moves into recesses 35 in the levers 31a, 31b and the coin passes out of the pocket to a coin-return cup. If the required coins have been inserted, the uppermost coin in pocket 16 engages the pawl 19b and the coin in pocket 18 engages pawl 17a and both levers 12 tilt so that the coins fall to a cash box and the upper ends of the levers move clear of the block 15. As the bar 11 moves up, the pin 30 passes through the recesses 35 and the toes 26, 28 return to block the coin-return shoots. Where the price requires coins in one pocket only, the transfer means moves the bar 20 or 24 for the empty pocket up until it contacts a lever 23 or 25 which moves the corresponding lever 12 clear of the block 15. Where only one coin pocket is provided, the pawl may be disposed at a level corresponding to the total diameter of two coins of different values or pawls may be disposed at different levels so that one more spaces may accommodate more than one coin and the other spaces a single coin.

Title: Improvements in or relating to the manufacture of printers' rollers or like printers' devices
IPC: B41N7/06
Filed: 1931-10-09
Abstract: Rubber mixed with a high proportion of an oily softener is cast in moulds and vulcanized to produce printers' rollers.  The mixtures are generally capable of being cast at temperatures not exceeding 100 DEG C. and accelerators are included so that vulcanization may be effected in the open by maintaining the casting-temperature for a few hours.  Alternatively, a small quantity of sulphur chloride may be stirred into the liquid mix. In a modified process, a high proportion of oil is emulsified in latex and the mixture cast and vulcanized. The softener may be a non-volatile mineral oil or jelly or an animal or vegetable oil or a mixture.  When used alone, a solid oil such as palm oil gives a relatively hard product, but waxes or fats of high melting point are not suitable.  The proportion of softener is higher than can be incorporated by milling: the raw rubber is generally milled with sulphur, zinc oxide, a little softener and other filters if required, and the dispersed in the main portion of oil with the aid of gentle heat, the accelerator mixed with more softener being subsequently added.  In typical examples the proportions of rubber and softener are as follows: (1) 100 parts of rubber, 10 parts of zinc oxide, 25 parts of palm oil, 5 parts of sulphur, 175 parts of petroleum jelly, 1 part of diphenylguanidine, and 0,5 parts of mercaptothiazole, moulded and vulcanized at 100 DEG  C. for 2 hours; (3) 100 parts of rubber, 75 parts of sulphur, 20 parts of zinc oxide, 100 parts of whiting, 50 parts of palm oil, 400 parts of spindle oil, 4 parts of zinc diethyl dithiocarbamate, moulded and vulcanized at 100 DEG  C. for 16 hours; (5) 250 c.c. latex (40 per cent rubber), 3 grams of sulphur, 20 grams of zinc oxide, 0,5 grams of piperidine pentamethylene dithiocarbamate, 250 c.c. spindle oil, 10-20 c.c. glycerine, shaken to form an emulsion, poured into a mould and heated in a water oven for an hour.
