Title: Improvements in internal fittings for cardboard boxes for containing electric lamps and like articles
IPC: B65D5/50
Filed: 1929-09-18
Abstract: 338,271. Brown, A. A. Sept. 18, 1929. Fittings, internal.-A box for a single electric lamp &c. has an internal liner for all the sides of the box, the liner being creased, corrugated, or scored transversely between its ends to enable it to be deformed by endwise pressure and grip the article in the box; openings are provided at the corners of the liner so that the sides yield or buckle inwards under the endwise pressure, the liner thus adapting itself to the size and shape of the article. As shown in Fig. 1 the liner 16 is made of corrugated cardboard and is creased across the corrugations 16<a> to form the corners of the liner where portions are cut away to form openings 17. The length of the liner is slightly greater than the length of the box minus the depth of a flanged apertured platform 19 in which the lamp bulb 18 is suspended so that, when the lamp is placed in the liner with the platform 19 resting on the top edges of the latter, and the flaps 14, 15 of the box are closed, the platform 19 is pressed down and deforms the liner, the sides of which buckle inwards and press yieldingly against the bulb 18. The position and shape of the openings 17 are determined by the size and shape of the article to be enclosed in the liner and the openings 17<a> Fig. 6, may also be formed near the upper end of the liner to support the cap portions of a lamp bulb or thermionic valve. The platform 19 may be formed in one with the liner or it may be dispensed with and the liner deformed by confining it between the bottom and closing flaps of the box and in this case the liner may be fixed to the box at parts which are not required to buckle inwards. The liner may be deformed by a pair of end flaps on the box which are turned in to lock with the cap of the lamp bulb &c. or the locking flaps may be formed on the liner and engaged bv the closing flaps of the box: one or more elastic bands may be fitted around the liner to increase its resilience.

Abstract: 693,453. Spotting mica. BRITISH THOMSON-HOUSTON CO., Ltd., SNADOW, R., PARRISS, W. H., and BAKER, B. S. Nov. 13, 1951 [Nov. 21, 1950], No. 28427/50. Class 124. In a method of treating mica splittings to separate them into smaller and thinner flakes, a liquid suspension of the splittings is subjected to supersonic vibrations. The frequency and intensity of the vibrations are preferably at least 500 kc/s. and 250 watts/ sq. cm. respectively, and the splittings arranged to flow so that their cleavage planes are generally normal to the axis of the supersonic energy beam. As shown, apparatus for carrying out the method comprises a supersonic generator A, water section B, a polythene window C and an exponential horn D through which the suspension flows. Flow of liquid past the plate F causes the splittings to be correctly orientated at this point, where the intensity of the vibrations is sufficiently great. Flakes of suitable size may be separated by settling and then heat-treated with concentrated HCl before compressing into a felted layer. Specifications 591,388, [Group VIII], 662,057, [Group XL (b)], and U.S.A. Specification 2,380,741 are referred to.

IPC: H05G1/38
Filed: 1937-10-19
Abstract: 484,281. Photo - electric control of R÷ntgen - ray apparatus. SIEMENS - REINIGER-WERKE AKT.-GES. Oct. 19, 1937, Nos. 28488, 28489, and 28490. Convention dates, Oct. 19, 1936, Oct. 31, 1936, and Aug. 5, 1937. [Class 40 (iii)] [Also in Group XXXV] A photo-electric cell or other light-sensitive device is subjected to the light from the focus of a R÷ntgen tube to control the tube to prevent its overloading. For example, a mirror 13, Fig. 11, is mounted in the diaphragm housing 29 of the earthed casing 27 of a R÷ntgen tube 1 so as to reflect the light coming through aperture 28 from focus of tube to an optical system 5, which throws the light on a photo-electric cell 6. The current from the cell may control a relay to switch the R÷ntgen tube off when the light exceeds a predetermined value. In a modification, Fig. 2, the current from the cell 6 flows through a resistance 11 causing discharge of a tube 10 through a resistance 12, which in turn causes interruption of discharge of a tube 9, whereby the R÷ntgen tube 1 is switched off. In another modification, the R÷ntgen tube is switched on and off by a valve connected to a discharge tube device or a trigger circuit operated by an amplifying valve controlled by the cell. In the form shown in Fig. 5, the cell controls the bias of a grid 20 in the R÷ntgen tube and thereby maintains its emission substantially constant. In another form, Fig. 9, the cell controls the alternating current heating circuit of the R÷ntgen tube ; and in a modification of this the heating is performed by direct current from a valve controlled by the cell.

Title: Improvements in or relating to a windshield cleaning system
IPC: B60S1/48
Filed: 1954-10-05
Abstract: 758,499. Windscreen washers. TRICO PRODUCTS CORPORATION. Oct. 5. 1954 [Oct. 19, 1953], No. 28671/54. Class 138(1) A windscreen cleaning system for a motor vehicle 1 Fig. 1. has a primary source of suction derived from the intake manifold 3 of the vehicle engine 2, a washer pump 12 for delivering liquid through nozzles 14 on to the windshield 8, an engine-driven auxiliary source of motion (e.g. crankcase ventilating pump 6), and a valve mechanism 11 to which the primary and auxiliary sources of suction, the pump 12 and a wiper motor 5 are connected and by which the washer pump is automatically placed in communication with the source of suction of greater magnitude, when the system is in operation. Referring to Fig. 2, the valve mechanism 11 comprises casing parts 17. 17<SP>1</SP>, of which 17 has two chambers 21, 21<SP>1</SP> and 17<SP>1</SP> is provided with a passageway 24 connected to bores 26, 26<SP>1</SP> and a nipple 25. A flexible diaphragm 18 has flaps 27. 27<SP>1</SP> to co-operate with the bores 26, 26<SP>1</SP>. The chamber 21 is connected by tubes 4, 4', with the manifold 3 and motor 5, whilst the chamber 21<SP>1</SP> is connected by tubes 7, 7<SP>1</SP> with the pump 6 and the motor 5. The nipple 25 is connected to the washer pump 12 by a tube 13, and the pump may be of the type disclosed in Specification 757.231. When the magnitude of the manifold suction is greater than that of the pump 6, i.e. at low engine speeds, the flap 27 adopts the dotted line position since the pressure in the chamber 21 is less than the atmospheric pressure normally existing in the passage 24. With the bore 26 uncovered the pressure in the passageway 24 will drop and as the degree of vacuum in the chamber 21<SP>1</SP> operated by the pump 6 is normally less than that in the chamber 21 the flap 27<SP>1</SP> is moved into the dotted line position to prevent oil being sucked-up out of the crankcase. When the vehicle is accelerated the manifold suction decreases and the pressure at the intake side of the pump 6 drops, due to the increased engine speed. Conseauently the flaps reverse and adopt the full line positions, the pump 12 then being actuatable by the suction of the pump 6. Since in this instance the valve 27 is closed petrol will not be sucked out of the manifold 3.

Title: Manufacture of compositions containing sodium triphosphate
IPC: C01B25/41
Filed: 1955-10-10
Abstract: <PICT:0788682/III/1> Sodium triphosphate in the low temperature modification is prepared by dehydrating one or more sodium ortho-phosphates and/or pyrophosphates at a temperature below 450 DEG C. in an atmosphere containing from 20-100 per cent by volume of water vapour.  The dehydration of the starting phosphates may be effected by heating powdered mixtures thereof in a humid atmosphere, but is preferably effected by spray drying solutions thereof in a gaseous phase consisting of superheated water vapour with a temperature of 200 DEG  to 450 DEG  C.  The solution may be sprayed through a binary nozzle by means of water vapour or a mixture containing it, under pressure, and in addition superheated water vapour may be injected into the spraying tower preferably so that it strikes the sprayed phosphate solution as it enters.  As shown in the drawing a vessel 1 is fed with water, sodium carbonate and ortho-phosphoric acid from pipes 3, 4 and 5 and the solution so formed is pumped by pump 6 to a spraying nozzle 7 in a tower 8. Superheated steam from heater 10 at a temperature of about 420 DEG C. is passed in at 9 around the nozzle 7 and air heated to 450 DEG C. is passed in at 11.  The gases leave the spraying tower at 14 at about 300 DEG  to 350 DEG  C. and the sodium triphosphate product is removed by a conveyer 15.  The waste gases pass through a dust remover 18 and a heat exchanger 12 where their heat is transferred to fresh air entering the system for supply to the spraying tower by means of line 11.  Examples refer to the dehydration of a finely-powdered mixture containing disodium phosphate and monosodium phosphate in a molar proportion of 2 : 1 at 400 DEG  C., the starting phosphate being placed in a heated tube through which is passed air and water vapour; a further example describes the neutralization of ortho-phosphoric acid with sodium carbonate solution to obtain a starting phosphate which is sprayed at 6 atmospheres pressure into a spraying tower through which air at 450 DEG  C. is passed. Additional water vapour is blown into the tower so that the waste gas leaving the tower contains 40 per cent by volume of water vapour.  The sodium triphosphate formed leaves the tower at 350 DEG  C., and contains 98 per cent of the low temperature form.
