Patent GB-1093281-A (GB)
Title: 3-pyrazolidones and their use as photographic developers
Inventor: MIJOVIC MIROSLAV VASA
IPC: G03C5/30
Filed: 1963-03-22
Abstract: The invention comprises 2-pyrazolidones of the general formula <FORM:1093281/C2/1> in which R1 is a hydroxyalkyl group, R2 is an alkyl, hydroxyalkyl or substituted alkyl group in which the alkyl group contains 1-4 carbon atoms, and R3 is an aryl group.  The compounds of the above formula in which both R1 and R2 are hydroxyalkyl can be made by first reacting under reflux an acetoxymethyl-dilacetoxyalkyl) acetyl halide with an aryl hydrazine, which may be substituted in the benzene nucleus, to form a 1 - aryl - 2 - [2 - acetoxymethyl - 2,2 - di-(acetoxyalkyl) acet] hydrazide which is treated with ammonia to form the corresponding 1-aryl-2 - [2 - hydroxy methyl - 2,2 - di - (hydroxyalkyl) - acet] - hydrazide which is then subjected to ring closure.  Those compounds in which R2 is not an hydroxy alkyl group may be made by an analogous method using as starting material a compound containing one acetoxyalkyl group and the required group R2 instead of the second acetoxyalkyl group. In the examples (a) pentaerythritol is oxidized to trihydroxymethylaceti acid; this is treated with acetic anhydride to give triacetoxyacetic acid and this is reacted with sulphuryl chloride to give the acid chloride; the acid chloride is reacted with phenylhydrazine to give the acethydrazide; the acethydrazide is treated with ammonia to form 1-phenyl-2,2,2-trihydroxymethyl - acethydrazide and this is heated with anhydrous p-toluene sulphonic acid to give 4,4 - dihydroxymethyl - 1 - phenylpyrazolid - 3 - one; and (b) 4,4 - dihydroxymethyl - 1 - p - tolylpyrazolid - 3 - one and 4-hydroxymethyl - 4 - methyl - 1 - phenylpyrazolid-3-one are prepared by analogous methods.

Title: Improvements in or relating to servo-assisted brakes
IPC: B60T13/52
Filed: 1965-03-18
Abstract: 1,093,598. Fluid pressure brakes. BENDIX CORPORATION. March 18, 1965 [March 23, 1964], No. 11602/65. Heading F2F. A vehicle braking system has a first servo 16 actuated by a master cylinder 12 and controlling one set of brakes, and a second servo 18 controlling a second set of brakes and actuated by the first servo through means adapted to vary the ratio of braking effort of the first and second sets of brakes in accordance with a load carried by the vehicle. As shown, a vacuumsuspended servo 16 supplies hydraulic pressure to the front brakes of a vehicle through a pipe 76 and is operated by hydraulic pressure from the master cylinder 12 which actuates a control valve 26 to produce a reduced vacuum controlling the servo 16 through a pipe 36 and also, through a pipe 38 acting on one side of a vacuum suspended diaphragm within a device 40 to move a rod 42 causing rotation of a cam 52. Through a lever-and-link system 150, 60 the ratio of which is adjusted by movement of the link 60, the rotary movement of the cam is translated into linear movement of a valve actuating rod 64 to apply a reduced vacuum through a pipe 68 to control a vacuum suspended slave servo 18 which is supplied with hydraulic fluid through a pipe 22 and which actuates the rear vehicle brakes through a pipe 74. The ratio of front to rear braking effort is adjusted by moving the link 60 with a link 144 connected to a lever 142 which is positioned in accordance with the load on the vehicle wheels. The valve, Fig. 3 (not shown), which is actuated by the rod 64, comprises a housing 96, 98 having a vacuum connection 132 and a diaphragm 104 both sides of which are normally connected to the source of vacuum through passages 130 and 134. The diaphragm is urged leftwards by a spring 122. Rightward movement of the rod 64 causes a poppet valve 116 to close the passage 130 and admit air to the left hand side of the diaphragm so that the latter is moved rightwards against the spring 122, reaching a balanced condition at a reduced degree of vacuum which is communicated to the servo 18 through a passage 136a, a connection 140 and the pipe 68.
