Abstract: 353,183. Interrupters. PERL, A. H. F., 46, Oxford Road, Acooks Green, Birming- ham. June 14, 1930, No. 18302. [Class 38 (v).] A tool or holder for facilitating the adjustment of the contacts of a contact-breaker consists, Fig. 2, of a cup-like casing 1 made of Bakelite at the centre of which is secured a fixed post 2 on which the contact-breaker is secured after detachment from the magneto, being held in position by a securing nut 4. The flanged portion 8 of the holder is formed with a number of recesses 9 the projections 10 between which form cam points corresponding to the fixed cams of the magneto within which the contact-breaker normally rotates so that by rotating the contact-breaker on the support 2 the tip 12 of the contact lever may be brought into engagement with one of such cam points and the gap between the contacts may be adjusted. The cam points of the holder may be of different heights corresponding to the cams of various makes of magnetos. A number of ridges 7, Fig. 3, are formed on the internal surface conical annular 6 recess for receiving tapered end of the contact-breaker base, the space between the ridges providing for different positions of the keyway on this end. The securing nut 4 is provided with a coned end 5 and the spindle 2 with a conical portion 3 so that the contact-breaker base may be accurately positioned in relation to the cam points. A cover 11 may be provided. In an alternative form, Fig. 4, the tool or holder comprises a pair of pivoted arms 17, 18 pressed apart by a spring 23 and carrying a post 2 on the arm 17 on which the contact-breaker base may be mounted for adjustment. Mounted on the other arm is a cam point 16 which is so arranged that when the tips 20 are adjusted to a distance a between opposite cams in the magneto cam-ring the distance b of the post 16 from the supporting spindle 2 is exactly half this distance so that if the contact-breaker base is rotated until the post 16 engages the contact lever an accurate setting of the contact gap may be effected. The adjustment of the arms is effected by a nut 22 on a spindle 21 extending between the arms.

IPC: G03F5/12
Filed: 1933-12-16
Abstract: 415,628. Photo-mechanical printing- surfaces. WESSTROM, R., Rotebro, and OLSON, G. V. H., Stockholm, both in Sweden. Dec. 16, 1933, No. 35495. Convention date, March 13. [Class 98 (ii).] In a method of making printing blocks from originals which include half-tones, a screen is used having two sets of transparent elements, coloured in substantially complementary colours, in place of the usual transparent and opaque elements, and the half-tones of the original are coloured in correspondence with one of the colours of the screen. A screen consisting of two sets of yellow lines crossing at right-angles may be used, the intervening square spaces being coloured blue-violet. The half-tones are then given a wash of blue-violet colour. The sensitive emulsion is so chosen that the white parts of the original give an approximately equal blackening under both parts of the screen. In the half tones, the yellow lines absorb the light and thus act like the opaque lines of the usual autotype screen. Suitable dyes for the screen are Metanil Yellow and Victoria Blue.

Patent GB-952655-A (GB)
Title: Granulated dry dough, cooked food product made of such dough and method of making the said food product
IPC: A21D13/00
Filed: 1961-10-04
Abstract: A granulated dry dough of reduced moisture content from which food products such as biscuits, cookies, crackers and animal foods can be prepared, consists of dry separate dough granules having a low moisture content equal to about 75% of the moisture required to cohere the dough granules in a unified body and disposed loosely in non-embedding, non-adherent engagement with each other. A cooked food product is produced by forming a cream mass of sugar, shortening and/or water, incorporating the cream mass in flour in such proportions as to form the dry dough, comminuting the dry dough into separate, non-adherent granules, depositing the granules on a supporting surface and treating them with water solutions, fats or oil, baking the deposited granules to fuse the granules together and cutting the baked product to pre-selected shape and size.  In the dry dough for each 100 parts of flour there is preferably 7 to 17 parts of water, 17 to 70 parts of sugar, and between zero and 25 parts of shortening.  The dry dough granules may be intermingled with granules of additive ingredients of similar size, preferably between 5 and 24 mesh, to form a loose, flowable mass.  According to an example, a dough batch is prepared by mixing 100 parts flour with a cream mass consisting of 33 parts sugar, 16 parts shortening and 9 parts water, until a dry dough of proper consistency for granulating is formed. The dough is comminuted in a granulator and screened to form a loose mixture of coarse, dry dough granules of between 7 and 16 mesh particle size.  Dough mixtures prepared by intimately mixing the dough granules with granules of nut, chocolate and coconut are baked at a temperature of about 400 DEG F. for 7 minutes to make cookies in which the respective surface granules of dough, nut, chocolate and coconut, respectively, are still identifiable in the fused or baked state.  In further examples there are included in the dough mixture the following colouring and flavouring additives: apricot, blackberry, and lemon with or without chocolate.  Yet a further example is directed to a yeast-containing dough batch for bread. Other additive ingredients mentioned are: seeds, fruits (including dried and candied fruits), candies, gumdrops and peels.  For a dog food, meat, tomato pumice and meat meal may be included.

Title: Improvements in and relating to electric switches having arcing contacts
IPC: H01H33/12
Filed: 1946-12-03
Abstract: 619,343. High-tension switches. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 3, 1946, No. 35815. Convention date, Dec. 4, 1945. [Class 38 (v)] A switch suitable for disconnecting small currents such as the magnetizing current of a power transformer 2 has arcing contacts 17, 18 in an evacuated envelope 16 which are connected in circuit before the main fixed and moving contacts 10, 11 break, and are separated afterwards to take the arc. The switch housing 6 may contain a liquid insulating dielectric as disclosed in Specification 601,572, [Group XXXVI], and pivotally supports at 12 the main contact 11 having a contact ring 13 engaged by fingers 14. The movable arcing contact 18 is mounted on a conducting rod 20 piercing a thin metallic diaphragm 21 whereby it is spring-biassed to the closed position. A pivoted lever 25 electrically connected to the rod 20 is held by a spring 29 in a mid-position with the arm 27 normally spaced from the end 22 of the rod. A conducting cam surface 32 on an insulating support 31 is connected to the fixed main contact 10. As the contact 11 moves counterclockwise to open the switch, the end 26 of the lever 25 engages the cam surface 32 and completes a shunt circuit to the contacts 10, 11 which then separate. Further movement causes a depending portion 33 of the cam surface to rotate the lever 25 clockwise, and the arm 27 moves the rod 20 to open the arcing contacts 17, 18. On closure of the switch, the lever 25 is rotated counterclockwise by the insulating support 31, whereby the shunt circuit through the cam surface 32 is not completed until the main contacts 10, 11 have engaged and taken the high inrush current, thereby avoiding damage to the contacts 17, 18 by transformer-inrush currents.
