Title: A new or improved process of manufacture of boot or shoe trees of celluloid or othersimilar plastic material
IPC: B29C35/04
Filed: 1932-02-10
Abstract: Boot or shoe trees are formed of celluloid or similar plastic sheet material by softening a blank in a bath of oil, e.g. olive oil, molten wax, e.g. paraffin wax, or other liquid or fused substance which is heated to a temperature higher than the boiling point of water and which does not cause distortion of the wood of the last. The last and celluloid blank are immersed together in the heated liquid, and the blank is blocked on to the last, which is then withdrawn from the liquid, whereupon the celluloid cools and sets and can be immediately taken off the last.  Full length, half length and other trees may be formed by the process.

[Class 83 (iii).] A broach has a series of successive broaching teeth 32, 33, all of substantially the same height, each tooth having spaced cutting edges disposed at acute angles to the finished surface, Fig. 8, of the opening d to be formed, whereby after the first cutting teeth have made a series of cuts a, b in the work, the following teeth remove successively relatively thin strips c of material each to substantially the full depth of the opening d. In a modification, for broaching a square hole from a round one, Fig. 14, the first broaching teeth take a series of cuts f while the subsequent teeth remove the remaining metal by a series of cuts g. In a further modification, Fig. 20, for enlarging a square hole, the first series of teeth gradually increase in height and approach a square section having diagonals equal in length and parallel to the sides of the finished square hole. These teeth take a series of cuts k while subsequent teeth gradually increase in width but not in height to a square section equal in size to the finished hole so that they complete the hole by taking a series of cuts l.

Patent GB-356645-A (GB)
Title: Improvements in or relating to the manufacture of ammonia by the contact process
IPC: C01C1/04
Filed: 1931-02-16
Abstract: <PICT:0356645/III/1> The hydrogen used in ammonia synthesis is generated at the requisite initial pressure by electrolysis in a closed pressure vessel.  Preferably the pressure is such that on mixing with nitrogen at atmospheric pressure the mixture is sufficiently compressed to enable a multistage synthesizer to be used.  In the illustrated apparatus the electrolyte is fed from containers b, c into the gas chambers of the pressure vessel a in which p  electrolysis takes place.  The gas chambers and the exit pipes e are of small capacity and the latter are heated to effect recombination of the small quantity of each gas which may contaminate the other gas.  The hydrogen is collected in the container f and mixed with nitrogen at atmospheric pressure in the vessel g.  The mixture is passed through a series of reaction chambers h each followed by a washer i where the ammonia is removed.  The fall in pressure as the gas passes through the system should be only slight until the penultimate vessel has been traversed.

Title: Improvements in or relating to television, tele-cinematograph, radar and like signalsystems
Inventor: JESTY LESLIE CONNOCK
IPC: G01S7/28
Filed: 1950-02-28
Abstract: 701,902. Television. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Nov. 3, 1950 [Feb. 28, 1950]. No. 5107/50. Class 40 (3). [Also in Group XL(c)] In an interlaced television system, the scanning spot is oscillated at a high-frequency so as to explore, in each scan, the whole of the target electrode on which the signals are stored, and the output circuit is gated during the scan so that, although all the stored signals are wiped out, only those appropriate to the scan are passed. The arrangement is stated to eliminate distortion caused by interference with the storage of a succeeding image by those parts of the preceding image left unscanned. In the system illustrated, which is a sequential-field, line-interlaced, colour system, the scanning spot is given the normal line and field deflections by sources 2, 3 and, in addition, is given a supplementary high frequency deflection at right angles to the line direction by source 4 applied through shaping circuit 5. Preferably this oscillation is of square wave form although a satisfactory result is obtained by using a sinusoid plus the third harmonic. The frequency of the oscillation is several times picture point frequency, and the amplitude is made equal to a line width whereby during each interlaced scan the regions of the intervening lines are covered and signals from the whole of the target area are wiped off. In order, however, to take off only the signals required, the output across resistor 6 is "sampled" by a gate stage 7 opened under the control of source 4 only when the spot is traversing the line appropriate to the scan. A low-pass filter 10 eliminates the high-frequency oscillation component from the output. The invention may be applied to a dot and line interlaced system, the gate in this case being opened under joint control of the high-frequency oscillation and the dot oscillation. The invention is also of application in a radar system where a television camera operating with conventional interlaced scanning observes a P.P.I. type of display to derive signals for transmission to a remote point. Reference is made to tele-kinematograph systems.
