Title: Process of vulcanizing rubber and products obtained thereby
IPC: C08K5/00
Filed: 1931-10-14
Abstract: The vulcanization of rubber is accelerated by the addition to the mix of a salt of guanidine or of a substituted guanidine with an organic acid, in admixture with one or more other accelerating compounds. The action is to retard vulcanization at low steam pressures, and to act rapidly at normal vulcanization temperature.  Examples are given. Among the salts mentioned are diphenylguanidine benzoate, acetate, phthalate, guanidine acetate and phthalate and similar salts of di-, ortho-, tolylguanidine, and dixylylguanidine.  Compounds mentioned for use with the salts of guanidine are the reaction product of a mercaptoarylthiazole and an aromatic acid halide; the crotonaldehyde derivative of the reaction product of mercaptobenzothiazole and hexamethylenetetramine; and the acetaldehyde derivative of the reaction product of p-p1-diaminodiphenylmethane and mercaptobenzothiazole.  Specifications 362,862 and 388,432 are referred to.  The Specification as open to inspection under Sect. 91 comprises also the use of inorganic salts of guanidines and substituted guanidines.

Title: Hydraulic controls
IPC: F15B1/26
Filed: 1976-07-09
Abstract: 1500878 Hydraulic control circuits INTERNATIONAL HARVESTER CO 9 July 1976 [24 July 1975] 28637/76 Heading F1P In the circuit shown, Fig. 1, which includes a pressure relief valve 5, a valve 17 is provided, operated by a float 19 in the reservoir, which diverts fluid in the output line to the input line when the level in the reservoir falls below a predetermined level. In a normal operation, a portion of the fluid in line 4 is directed to a control line 7 and a throttle 8 to establish a pressure which holds the valve 5 in the position shown in Fig. 1 against an opening 6. If a leak occurs in the line 9, the level in the reservoir drops and the float 19 opens the valve 17. This allows fluid in the control line 16 to escape into the reservoir. Simultaneously pressure in the control line drops and the spool of valve 5 moves to the right. This causes valve 13 to divert fluid from line 4 through line 14 to the intake line 2. This prevents further losses and ensures the pump does not run dry. The valve 17, Fig. 2, may also be opened by high-pressure peaks acting on a face 33 through a line 25. Fig. 3 (not shown), illustrates an alternative construction of'the valve 5.

Class 68(2) [Also in Group XXXVII] An electrically driven drainage installation for a floating dock having a plurality of individual compartments is characterized in that an underwater impeller pump 11, combined with its electric drive motor 8 to form a single unit 7, is installed in each separate compartment b. Each pump unit 7, built into a section of pipe 9, is reversible so that it can assist in the flooding, as well as the draining, of the dock. A slide valve, not shown, is associated with each pump to render complete cutting off possible, and in order to be able to drain the corresponding compartment in the event of the failure of one pump, a communicating slide valve is installed between each pair of dock compartments The installation is provided with a common. switching device which can be selected to drive the motors for draining or flooding, the power to the pump motors being delayed however until the slide valves have been completely opened by auxiliary motors. The time delay can be effected either by incorporating time delay relays, or by providing switches in the power cables to the pumps which are only switched on when the associated slide valves are fully open. When the pumps are switched off the auxiliary motors close the slide valves and then are switched off. A lamp on the switchboard indicates when the slide valves are shut and other lamps indicate whether the slide valves are being opened, or closed.

Title: Devices for feeding superposed webs of paper in an autographic register
IPC: B41L5/06
Filed: 1924-12-04
Abstract: 231,425. Macdonald, M. March 31, 1924, [Convention date]. Memorandum appliances.-In an autographic register, superposed paper webs 31, Figs. 1 and 2, are kept in longitudinal alignment by feeding- mechanism which comprises two pairs of oppositely disposed feed rolls, each pair consisting of a positively driven roll and an idle roll, the rolls 19, 30 of one pair being intermittently inoperative for the normal feed, and the rolls 28, 26 of the other pair being arranged to become operative during the period of inoperation of the first pair. Part of each positively driven roll 19 is cut away, forming a flat surface 23, so that at this point the roll 19 ceases to drive the web and the drive is then taken up by the other pair of rolls 26, 28. The rolls 26, 28 feed the paper through at a slightly greater speed than the rolls 19, 30. Perforations 32, Fig. 11, are provided in the webs so that any web which was in advance would momentarily not be fed owing to its perforation intervening between the rolls, 19, 30, while any web lagging behind would be given an accelerated feed. Each idle roll 26 is yieldingly mounted between the driven roll 19 and a plate 20, its axle 25 being movable in slots 24 but urged outwards by springs 27. The feed rolls 28 on the shaft 13 are driven from the handle 4 through gear wheels 14, 15, which are proportioned to give a slightly greater peripheral speed to the rolls 28 than the peripheral speed of the rolls 19 which are on the handle shaft 3. The shaft 13 is mounted in end plates 7 slidable in bearing plates 6 but acted on by springs 11 to keep the upper rolls in engagement with the lower rolls. A spring-actuated pin 5 projects into the path of the handle 4 so as to determine one complete revolution of the handle.
