Abstract: 453,039. Delivering measured quantities of granular materials. PIGNOLY, F. M., 6, Avenu Leedru Rollin, Pertuis, France. Dec. 3, 1935, Nos. 33535 and 33536. Convention dates, Dec. 3, 1934 and May 9, 1935. [Class 106 (v)] [See also Group XXIX] In apparatus for delivering measured quantities of granular materials including a measuring chamber having upper and lower openings controlled by reciprocating valve members 12, 13 and at least one of the walls displaceable for varying the capacity of the chamber, each displaceable wall comprises two flaps 3, Fig. 2, oscillatable between and pivoted at 4 to opposite fixed walls of the chamber and extending towards one another and additional flaps 5 slidably connected as at 6 to the flaps 4 and pivotally connected to a common transversely adjustable axis at 7. The displaceable wall is moved by means of a milled nut 10 revolvable in a support 9 and co-operating with a screwed rod 8. Graduations r on one of the opposite fixed walls of the chamber indicate the capacity of the chamber. The valves 12 and 13 are actuated by arms 14, 15 pivoted to a fixed spindle 16 and carrying rollers 17 and 22 respectively, riding in a slot 18 cut in a plate 19 which may be reciprocated vertically by means of lever 21. In the position shown in Fig. 3, the lower valve is closed and the upper valve open. As the plate 19 is moved downwardly the roller 22 of the arm 15 rides idly in a lower vertical portion of the slot while the roller 17 is forced along an inclined part of the slot to effect the closing of the valve 12. On further downward movement of the plate, the roller 17 rides idly in an upper vertical portion of the slot and the roller 22 is forced along the inclined part to effect the opening of the valve 13. The movements are reversed when the plate is raised. In order to avoid crushing the material, the valve 12 in its closed position is spaced from the wall of the measuring chamber by a gap 29 which is protected by an inclined wall 31 whose lower end 30 is spaced from the top of the valve.

Abstract: 1534168 Bandwidth economy systems PATELHOLD PATENTVERWERTUNGS & ELEKTROHOLDING AG 16 Aug 1976 [19 Aug 1975] 34066/76 Heading H4R An audio signal is split into at least two frequency bands, Fa, Fb, Fig. 7, the lowest frequency band Fa, is completely transmitted and the, or each, other frequency band Fb is divided by periodic suppression into reduced signal sections B 1r , B 2r , which, on reception are repeated to fill the gaps between the sections, Fig. 7(f) as described the reduced sections B 1r , B 2r  etc., can be time expanded and frequency compressed to provide a reduction in bandwidth in the transmitted signal Fig. 7(d), alternatively a similarly treated signal can be frequency inverted and the suppressed portions of each signal inter-digitated Fig. 13(d) to allow transmission of two signals with only a slight bandwidth increase on the bandwidth required for each signal. In a further alternative the signal is split into time segments T o  Fig. 15(a) in the upper frequency band a quarter of each time segment is transmitted, and the lower frequency band is time compressed, and frequency multiplied, so that it occupies a further quarter of the time segment, and the same frequency bandwidth as the upper frequency band, and the resulting signal, Fig. 15(b), is transmitted multiplexed in time with a further similarly treated signal. If more than one upper band is reduced the higher frequency bands can be reduced by a greater amount than the lower frequency bands without increasing the noise level on reproduction, Fig. 11 (not shown). Compression and expansion of frequency and time scale is achieved by feed into and reading out from a shift register at appropriately different rates and repetition is provided by recirculating shift register contents or by appropriately delaying the input signal to the receiver and reproducing the undelayed and delayed signal. Change of time scale and frequency band may require an appropriate correction of frequency shift by conventional means.

Title: Improvements in or relating to hydrogen peroxide
Inventor: HOLMES WILLIAM RAYMOND
IPC: C01B15/013
Filed: 1957-11-05
Abstract: <PICT:0889421/III/1> Hydrogen peroxide-water mixtures containing at least 61,2% H2O2 and contaminated with inorganic and/or organic impurities are purified by cooling the mixture to between -0,5 DEG and -56,1 DEG C. to form crystals, washing the crystals with an aqueous H2O2 solution having the same H2O2 concentration as the mother liquor in association with the crystals, but containing none, or less, of the impurities, separating the crystals and melting these to yield, together with associated wash solution, a purified H2O2 solution. Aqueous H2O2 solution is fed in at, or near, the top of a column C at A, the temperature of the contents of the column being maintained by cooling coil R.  Crystals of pure 100% w/w H2O2 form in zone C1C2, provided with agitator P, and fall and settle in zone C2C3.  A pure washing solution of H2O2, previously cooled to the same temperature as the liquor in the column, is introduced at W and continuously ascends the column countercurrent to the settling crystals, removing adherent mother liquor therefrom. Alternatively, depending upon the position of pipe W, the washing solution may pass through a bed of crystals settled in the column. Mother liquor and washing solution exit through overflow X, which contains a filter to remove entrained crystals.  Crystals settling in the column are forced by their weight, together with adherent washing solution, round the bend into heat exchanger H, heated by water to 15 DEG C., which melts the crystals, and the resulting pure H2O2 solution is removed.  A portion of this solution is diluted with distilled water to provide, after cooling, the wash solution.  Mother liquor and wash solution leaving the top of the column are concentrated, and returned to the column, after removal of impurities by purge.  Other methods include removal of crystals from a slurry produced by cooling the aqueous H2O2 solution, by filtration or centrifuging, washing the separated crystals as before, and finally melting the crystals to form the pure solution.  Specifications 465,070 and 590,439 are referred to.

Abstract: 629,098. Rivets. HUCK MANUFACTURING CO. Nov. 21, 1946, No. 34504. Convention date, Dec. 29, 1945. [Class 89 (i)] [Also in Group VII] A rivet for setting by a pulling-machine that uses the plates to be riveted as an abutment has a shank 15 that is a press fit in the plates 13, a grooved part 16 to receive a locking collar, a neck 21, at which the rivet will break after setting, and a grooved stem 23 for engagement by the jaws of the pulling-machine. The part and the groove may be enlarged to receive a sealing-washer. A collar 24 to form the other head slides on the shank and has a cylindrical part leading at 28 into a short cylindrical part 26 of greater diameter followed by a conical part 25. The setting-machine has an abutment-die 29 that bears on the collar and pulling-jaws 35 that close on the stem 23. The die is countersunk at 30 to fit the cone 25 and may be countersunk to a greater angle at 31. At the beginning of the stroke the collar exerts clamping pressure on the plates and the part 15 is drawn into the hole till the head abuts the plates. The die 29 is then forced over the collar upsetting it to fit the die externally and the grooves 16 internally after which the stem breaks at 21. On the return stroke an abutment 38 engages the end of the collar and ejects it from the die. In modifications the part 15 may have longitudinal or circumferential ridges to ensure tight engagement with the hole. The cylindrical part of the collar may be separate from the conical end and this may have a double taper initially to fit both parts of the countersink of the die 29. In a further form the rivet has a conical groove 46, Fig. 6, separated by a short cylindrical section from the breaking-neck 48, and the collar is a sleeve 50 that is forced into the space between the groove 46 and a countersink in the plate 13. The head 14 may be of countersunk or other form. This form of rivet is set by means such as that described in Specification 426,635, [Group VII].

Abstract: 810,418. Aerials. TELEFUNKEN G.m.b.H. Nov. 5, 1957 [Nov. 8, 1956], No. 34526/57. Class 40 (7). An aerial for use at very high frequencies comprises two closely mounted primary elements, one for transmission and one for reception, a beam forming element and a means for decoupling the energy paths to these primary elements. In one embodiment the primary elements are horns 2 and 3 (see Fig. 1) which are connected to waveguides 4 and 5 and which are directed towards a reflector 1. The guide 4 is used for transmission and the guide 5 for reception. An extension 6 of the guides' common wall forms a means for decoupling the two energy paths and consists of a conducting plate, the plate being, for example, rectangular and of dimensions of the order of the working wavelength. The primary elements are therefore associated with different parts of the reflector and so these two parts need not be of the same size. Other embodiments, Figs. 3 and 4 (not shown), illustrate aerials wherein the feeder guides pass through the reflector to the.primary elements; the extended common wall again providing the decoupling and in the case of dipole primary elements also forming the mounting means for these elements. In order to avoid radiation from the guide walls to the reflector in these latter embodiments a covering of a damping material may be affixed to the guide walls where they pass through the reflector.
