Patent GB-165775-A (GB)
IPC: F41A25/00
Filed: 1921-04-22
Abstract: 165,775. Schneider et Cie. June 28, 1920, [Convention date]. Ordnance, built - up; breech - mechanism. - In dismemberable mountain guns, the simultaneous assemblage of the breech-jacket with the gun barrel and with the gun slide is effected by rotation of the jacket, one of the elements of the firing-mechanism remaining inoperative until the assemblage is completed. The breech-jacket B, Figs. 4 and 5, has internal interrupted threads B<1> engaging corresponding threads A<1> on the barrel A and external interrupted threads b<1> engaging corresponding threads C<1> on the gun slide C. The gun barrel being first engaged with projections c, c<1> on the gun slide by a hook D' and a recess a<1> respectively, the breechjacket is slidden over the rear of the barrel until stopped by a continuous thread A<3>. The breechjacket is then rotated by a handle E which is finally turned down on a pivot e to cause an inclined projection E<1> to wedge against a surface a<2> on the barrel and thereby complete the locking movement imparted to the threads. In order to retain the handle, its grip portion E springs over a projection B<4> on the jacket. To prevent the gun being prematurely fired, the shaft f, Fig. 9, on the breech-jacket which carries the firing-hammer F has an arm f<1> which engages the firing rod G when the breech-jacket is fully rotated for locking. The firing-rod G carries an arm G<2> which engages between the threads b<1> to prevent operation of the firing-rod until complete rotation of the breech-jacket clears the arm G<2> and brings the arm f<1> on the hammer-shaft into register with a projection G<1> on the firing-rod G. The Specification as open to inspection under Sect. 91 (3) (a) also describes with reference to Fig. 9 (Canceled) an alternative construction of the safety device in which the shaft f carries an arm F' which moves clear of a stop c<3> on the gunslide only when the breech-jacket is fully rotated for locking. This subject-matter does not appear in the Specification as accepted.

Patent GB-741581-A (GB)
Title: Improvements in and relating to the production of di-esters
Inventor: REED HUGH WILMA BOULTON
IPC: C07C69/82
Filed: 1953-05-01
Abstract: Dialkyl terephthalates are produced by (i) decomposing at 200 DEG  to 650 DEG  C. a di-ester of a dialkyl cyclohexane-2:5-diol-1:4-dicarboxylate having a structure <FORM:0741581/IV(a)/1> where R and R1 are alkyl groups, to give a dialkyl cyclohexa-1:4-diene-1:4-dicarboxylate, and (ii) simultaneously or subsequently dehydrogenating this compound to give a dialkyl terephthalate.  Minor amounts of terephthalic acid and mono-alkyl terephthalate are also formed.  The preferred starting materials are those in which R and R1 are alkyl groups which contain less than four carbon atoms, for example the diacetate of dimethyl cyclohexane-2:5-diol - 1:4 - dicarboxylate.  The decomposition may be carried out by heating alone, in the presence of an inert contact material, or by passage through an unpacked heating zone. The dehydrogenation may be carried out thermally by heating the dialkyl ester at 350 DEG  to 650 DEG  C., catalytically by heating in the presence of a suitable catalyst such as a Group VIII metal or copper or an oxide of chromium, vanadium or molybdenum, or chemically by heating with selenium or sulphur at 150 DEG  to 300 DEG  C. or in the presence of a gas containing free oxygen.  Both reactions may be accomplished in a single step, for example by heating in the presence of a dehydrogenation catalyst at 200 DEG  to 650 DEG  C., or by passing through an unpacked heating zone at 350 DEG  to 650 DEG  C. In examples, dimethyl-2,5-diacetoxy - cyclohexane - 1,4 - dicarboxylate is treated to give dimethyl terephthalate by (1) heating a solution in toluene at 400 DEG  C. and at atmospheric pressure, in the presence of quartz chips, and dehydrogenating the diene by passing over glass beads at 500 DEG  C.; (2) passing a solution in toluene over quartz chips at 500 DEG  C. and at atmospheric pressure; (3) heating with a palladium catalyst at 300 DEG  C.  Di-esters of dialkyl cyclohexane-2,5-diol-1,4-dicarboxylate are prepared by treating a dialkyl succinate with a condensation agent such as sodium or sodium alkoxide to give a disodium derivative of a dialkyl cyclohexa-1,4-diene-2,5-diol-1,4-dicarboxylate.  This is either hydrolysed to remove the sodium atoms, hydrogenated and acylated, or acylated directly and then hydrogenated. Specification 741,107 is referred to.

Filed: 1927-05-07
Abstract: 276,280. Jackson, L. Mellersh-, (Sun Oil Co.). May 7, 1927. Force-feed lubricating; lubricant conveyed by fluid.-In an internal combustion engine having a cylinder and an intake manifold, means are provided to segregate a quantity of oil from a main supply when the engine is stopped and to introduce such segregated portion into the cylinder when the engine is started. As shown, a branch pipe o leads from the usual oil pump f to a receptacle i which may be mounted on the dashboard h and is in communication at its upper end, through a pipe n, with the intake manifold d of the engine. Within the chamber i a piston m forming an easy fit is held up against the head j, whilst the engine is running, by the suction in the pipe n and acts as a valve to close the orifice k, the lower part of the chamber being filled meantime with oil under pressure from the pump. When the engine is stopped, the oil is retained in the chamber by a check valve p and the piston m settles to the bottom. On re-starting, the oil above the piston is drawn by the suction into the manifold, the piston rising and again closing the orifice k to prevent leakage. Alternatively, the lubricant may be injected into the cylinders direct under the influence of the oil-pump pressure on the piston m.
