Patent GB-356932-A (GB)
Abstract: 356,932. Driving dynamos. SCHAFFLER, K. and SPARTALIS, N., (trading as SCHAFFLER & CO.), 138, Lerchenfelderstrasse, Vienna. Sept. 1, 1930, No. 26057. Convention date, Nov. 9, 1929. [Class 35.] In a spring-operated dynamo-electric mineigniting device of the kind in which the operating shaft 25 is held in the tensioned position by means of a detent pawl 9 and carries a disc 2 which co-operates with a pivoted abutment 10 on the pawl for maintaining the pawl inoperative while the dynamo is being driven by the spring, the operating shaft is fitted with a second disc 3 rotatable with respect to the first and entrained by it at the end of the movement, the releasing shaft 13 for the detent pawl being normally locked by a spring catch 14 which is engaged and released by the second disc on completion of the winding of the spring. The dynamo is driven by a toothed wheel 5 on the shaft 25, and the pawl 9 engages a ratchet 4 on the wheel 5 while the spring 1 is being tensioned through the shaft 8, pinion 7, gear wheel 5, pawl 51, and ratchet 2c formed on a hollow shaft 22 to which the inner end of the driving spring 1 is fixed. The disc 2 is rigid with the shaft 22 and during the winding of the spring, the direction of rotation is such that the abutment 10 is tripped by the frictional engagement with the disc 2 into a position which allows the detent pawl 9 to engage the ratchet 4. Towards the end of the movement the disc 3 is entrained by the engagement of a segmental projection 3a thereon with a stud 2b or an interrupted groove on the disc 2, and a cam 3b on the disc 3 engages an arm 14 which is thereby moved out of locking engagement with a notched disc 12 on the releasing shaft 13. The shaft 13 accordingly can be turned to raise the detent pawl 9 clear of the ratchet 4 through an arm 11, spring 11a and stud 9a. The abutment 10 is tilted by a spring against a shoulder on the pawl 9 and bears on the disc 2 so that the pawl is maintained clear of the ratchet 4 and the dynamo is driven by the unwinding of the spring. The cam 3b may operate a switch to control the ignition circuit. When the cam 3b rotates to its initial position it strikes a spring on the arm 14 which absorbs the shock and maintains the cam clear of the co-operating part of the arm so that the shaft 13 can be turned into locking engagement with the arm.

Each cylinder 52, 62 has an open end, the other end having an actuation chamber 57, 67, and between its ends has a valving recess 55, 65 between a first recess 51, 61 and a second recess 53, 63. The assembly has high-pressure passages 45, 64 leading from spaces 39, 36 connected with inlet 17 to recesses 51, 63, and has low-pressure passages 54, 46 leading from recesses 53, 61 to spaces 41, 43 connected to outlet 16. Chambers 57, 67 are connected by passages 58, 56 to the valving recesses 65, 55 of their paired cylinders. First and second sets of pistons 50, 60 reciprocate in cylinders 52, 62, each piston being recessed between its ends for valving fluid between the valving recesses 55, 65 and the first and second recesses 51, 61, 53, 63. Spring 59, 66 in chambers 57, 67 urge pistons 50, 60 outwards. Rotatably mounted on assembly 30 is an assembly 31 having interior six-lobed cam surfaces 76, 86. Links 72, 82 are pivotally attached to assembly 30 and have mounted thereon cam rollers 75, 85 which engage respective cam surfaces 76, 86, and rollers 70, 80 which engage pistons 50, 60 in an antifriction manner so as not to place any side load on these pistons. Then, as shown in Figs.3 3 and 4, if the assembly 31 rotates in direction R, and the piston 60c is fully extended, then as piston 60c is driven back into its cylinder 62c by cam surface 86 and will discharge fluid from chamber 67 through passage 56 into recess 55. Since the piston 50c is moving outwards, due to highpressure in chamber 57 from space 36, passage 64, channels 63, 65, and passage 58, it opens communication between recesses 55c and 53c, thus discharging fluid just received from chambers 67 to the low-pressure passage 54c.

Abstract: 522,555. Printing blocks of cellulose derivative compositions. HERBERTS, W. Dec. 16, 1938, Nos. 36667 and 36668. Convention dates, Dec. 17, 1937 and Jan. 6, 1938. [Class 2 (ii)] Printing blocks, including printing plates, cliches and the like, are made of a thermoplastic composition comprising a cellulose ether such as benzylcellulose, and a cumaron resin. Preferably the composition also contains a plasticizer. In making the composition, the cumaron resin may be melted preferably with addition of a plasticizer, and the cellulose ether is then added to the melt. A filler may also be added. In an example, hard cumaron resin is melted with an addition of tricresyl phosphate, and then benzylcellulose is added. Heavy spar or red ferric-oxide is added as a filler. The mass is shaped to the desired form. In addition to the cumaron resin, there may be present other polymerization products containing cumaron or indene. The composition may be used for replacing type metal for newspaper printing. During moulding its low heat conductivity prevents the mass from softening except for a thin superficial layer which attains a degree of fluidity such that, even in the case of large printing plates or rollers, the impressions are sharp and the finest half-tone dots are clearly reproduced. The composition takes up oily printing inks but is practically insoluble in oil and is highly resistant to corrosion by the inks.
