Patent GB-590326-A (GB)
Title: Improvements in or relating to electrical oscillatory circuits particularly in contact converters
IPC: H02M7/62
Filed: 1944-04-21
Abstract: 590,326. Converting. TELEFONAKTIEBOLAGET L. M. ERICSSON. April 21, 1944, No. 7444. Convention date, April 22, 1943. [Class 38 (ii)] In an electric contact converter wherein periodic, operation of a contact K supplies energy impulses from a source E to an oscillatory circuit C, L1, one or more rectifiers are arranged in parallel and/or series with the contact K to prevent sparking at " make " for a rated load R2 or for any lesser load. In Fig. 1, a parallel rectifier G is shown. Each time the contact K opens, the circuit C, L1 oscillates and the tuning is such that for the rated 'load, the voltage V across the condenser C as the result of the oscillation reaches the voltage E at the moment when contact K closes again. There is thus no voltage across the contact and no sparking. If the load R2 is smaller, the amplitude and frequency of the natural oscillation will both increase so that if the rectifier G were absent, the voltage V would exceed the voltage E at "make" and there would be sparking. The rectifier G allows the surplus voltage to be discharged through it and prevents the voltage V from exceeding the voltage E. In Fig. 3, this surplus discharge is used to energize a relay Q which keeps a contact S1 closed so long as the load is below certain value. Upon overload, the discharge impulses cease and the contact S1 opens. The relay R thus acts as an overload relay. In a modification, Fig. 4 (not shown), a rectifier is connected in series with the contact K and serves to prevent discharge of energy from the oscillatory circuit to the battery E. In other modifications, rectifiers are arranged both in series and in parallel and the invention is applied to converters in which current is alternately supplied to two transformers, the secondaries of which may supply D.C. or A.C. Specification 590,327 is referred to.

Title: Improvements in or relating to machines for operating upon marginal portions of shoe soles
IPC: A43D8/48
Filed: 1949-03-19
Abstract: 664,274. Skiving shoe soles. BRITISH UNITED SHOE MACHINERY CO., Ltd., BRAKER, R., and HEATHER, H. G. March 20, 1950 [March 19, 1949], No. 7535/49. Class 31 (i). In a machine for skiving shoe soles, e.g. cutting a feather edge on the sole portion and skiving the shank, in which the work is fed between a work support and the cutting means, means are provided for moving the cutting means bodily towards the work support before it is tilted, to enable the machine to skive shoe soles having shank and heel portions of less thickness than the sole portion. The machine described is a modification of that described in Specification 408,581 to which reference is made. A pin 203 provided on the block 45 projects through a slot 201 in the cover member 55. The forked horizontal portion 59 of the cover member is cut away at 205. When the chain 92 is pulled downwardly by the treadle, after the feather edge has been cut on the sole portion, the nut 53, stem 51, guideway 47, and knife carrier 49 are pulled downwardly against the action of the spring 63, which is weaker than the spring 93, until the lost motion is spent and the nut rests on the portion 59 of the cover member. Continued downward movement of the chain 92 then causes the knife carrier to move downwardly in the arcuate slot in the guideway 47 against the action of the spring 93 thereby tilting the knife for skiving the shank. The downward movement of the block 45 and guideway 47 may be limited by an adjustable stop 207.
