Title: Improvements in or relating to means for generating time modulated electrical pulses
IPC: C01F7/02
Filed: 1943-06-01
Abstract: 581,330. Pulse modulation. STANDARD TELEPHONES & CABLES, Ltd., and LEVY, M. M. June 1, 1943, No. 8797. [Class 40 (v)l A phase-modulated train of short electrical pulses is derived from a signal-modulated sinusoidal carrier wave by applying that wave as a synchronizing voltage to a pulse-generator. The carrier wave may be modulated by the signal in amplitude, phase, or frequency, and the normal pulse frequency is preferably a sub-multiple of the carrier wave frequency. As described, the pulses are generated by the circuits described in Specification 581,328, but as the carrier wave is modulated the phase of the pulses varies with the signal voltage. This is indicated in Fig. 11, where the pulse normally occurring at 6 at the intersection of the sawtooth 1 and the unmodulated carrier 4 is seen to occur in variable phase at 7 when the wave is modulated. Specification 578,690 also is referred to.

Title: Improvements in or relating to a pressure exchanger
Inventor: BROWN JAMES
IPC: F04F13/00
Filed: 1966-03-02
Abstract: 1,125,472. Pressure exchangers. POWER JETS (RESEARCH & DEVELOPMENT) Ltd. Jan.30, 1967 [March 2, 1966], No.9206/66. Heading F1N. The cell ring 1 of a pressure exchanger is rotatable between hollow end plate structures 2 having the surfaces thereof facing the cell ring formed from a plurality of arcuate plates 32 arranged end to end to form a ring and each being capable of limited sliding movement to permit radial and circumferential expansion thereof. Each end plate structure 2 comprises inner and outer concentric walls 13, 14 with an integral outer wall 16 and an inner wall 15 composed of the arcuate plates 32. To accommodate radial expansion the plates 32 have their inner arcuate edges positioned with radial clearance in a recess in a clamping ring 33 bolted to the wall 13 and their outer arcuate edges positioned with clearance in an annular recess between the outer wall 14 and the flange 35 of a casing 30 surrounding the cell ring 1. The radially extending edges of adjacent arcuate plates 32 overlap, Fig. 3 (not shown) to accommodate circumferential expansion. The inlet and outlet ports are each formed in a separate one of the arcuate plates 32. An inlet port 21, (Fig. 4) for hot gas is formed in the arcuate plate 32<SP>b</SP> and a duct 46 extends therefrom to an opening 23 in the outer wall 16. The duct 46 is protected from the hot gases by a lining 47 internally and externally cooled by a stream of cold gas supplied to the annular space between ducts 48, 49 connected to the opening 23. The arcuate plate adjacent to the plate 32b (lowermost in Fig. 1) is cooled by cold compressed gas bled off from the exchanger and supplied to a chamber 40 therein through a pipe 41. The cold gas leaves the chamber 40 through inner and outer arcuate rows of holes 36, 37 and impinges on labyrinth seals 6, 34 to thereby prevent hot gas leaking from the adjacent cells. Gas leaves the cells through an outlet port 20, Fig. 1, opening into a duct 42 internally cooled by a gas film leaking thereinto from the space between the end of the cell ring and the opposing end plate structure. The outside of the duct 42 is surrounded by a cover of heat insulating material 45. Gas which leaks into the central spaces of the cell ring and the peripheral space therearound flows through holes 61, 62 to annular galleries 54, 64 to cool the structure. Thereafter the gas flows through apertures 66, 57 into the space between the outlet duct 42 and an encircling outlet conduit 43. Gas compressed in the exchanger is also bled through a pipe 50 to an annular gallery 51. Part of the gas supplied to the gallery 51 passes through hollow struts 17 to the gallery 54 and port flows via an annular recess 59 to cool the edges of the arcuate plates 32.

Abstract: A liquid composition comprising a novolak and sufficient phenol to maintain the resin liquid is obtained by reacting phenol and formaldehyde in molar proportions of 1 to 0.5-0.725 in the presence of 0.2-0.8 per cent hydrochloric acid as catalyst at controlled temperatures of 35 DEG -60 DEG -85 DEG  C. for 4-5 hours, separating resinous and aqueous layers, and dehydrating the resinous layer under vacuum until a product having a resin solids content of 70-80 per cent is obtained; 1000 parts heated liquid phenol and 600 parts 37 per cent formaldehyde were mixed in a jacketed kettle with a stirrer, cold water being passed through the jacket until the reactants were cooled to 35 DEG  C., 14 parts of 20 DEG  Be.  HCl were then added and the temperature allowed to rise to 50 DEG  C. at the rate of half a degree per minute.  After an hour the temperature was allowed to rise to 60 DEG  C. at which it was maintained for two and one half hours.  The resin mixture was brought to a pH of 6-7 by addition of 50 per cent NaOH and triethanolamine or other emulsion breaking agent added.  An oily layer separated out which after removal of the aqueous layer was washed to remove salts and then dehydrated under 28-30 inches vacuum at 40-50 DEG  C. to a solids content of 78 per cent leaving dissolved therein about 5 per cent water.  The resin obtained had a 25 DEG  C. viscosity of 57,000 centipoises and may be used for coating particles of sand for use in making sand cores.

Abstract: 165,800. Hall, R. F. July 10, 1917. Blowing. - Relates to an automatic glassbottle blowing machine of the Owens type. The present invention relates to the frame of the machine and to cooling the moulds. Figs. 1<B> and 1<D>, taken together, show one arm of the machine. The under-frame 8 is mounted on four wheels 1 and its height can be adjusted by screws in casings 10, which can be worked simultaneously by one handle. A ballbearing ring 12 is supported at three points on the frame 8. The upper member 15 of the ball bearing carries hollow columns C, supporting hollow arms 28 which are bolted to a central chamber 26. The arm 28, column C, and apparatus carried by them constitute a complete bottle-forming unit, and can be removed from the machine without interfering with the other units. Cooling air passes from a fan &c. up a central trunk 150, through the chamber 26, along the arm 28, down the column C, through a hollow trunnion 31, to the finishing-mould carrier 110, from slots in which it issues close to the finishing-mould M.
