Title: Improvements in powder puffs and method of making the same
IPC: A45D33/34
Filed: 1936-06-24
Abstract: 466,236. Powder-puffs. MEYER, D., and HYGIENOL CO., Inc. June 24, 1936, No. 17569. [Class 131] A powder puff comprises a base having an inturned rim, the bent-over surface of which is connected to the base by adhesive, and the inner periphery of which defines a recess, and a piece of pile material located inside the recess wholly within the periphery and connected to the base by adhesive. The base consists of a strip of fabric 1, coated on one face with adhesive 2, and a sheet of heavy flexible paper 6 coated on each face with adhesive layers 7, 8. These are joined together under pressure and the base is bent by dies to the shape shown in Fig. 5. The pile fabric 9 coated with adhesive 11 and secured to adhesive-coated paper 6a fits into the recess of the base. The pile fabric may be cut by a tool which does not cut the upstanding fibres so that a puff as shown in Fig. 7 is obtained. Buckram, leather or imitation leather may replace the paper. The adhesives employed may be rubber cements or latex adhesives with or without fillers, vulcanizers and accelerators.

Title: Improvements in or relating to closures for collapsible tubes and the like
IPC: B65D35/42
Filed: 1948-06-30
Abstract: 652,486. Closures for collapsable tubes. LAING, C. June 30, 1948, No. 17572. [Class 125 (iii) ] A closure for a collapsable tube 1 comprises a preferably resilient sleeve 12, and a cap 4, which may be of resilient material, the lower part of the cap being cut to form arms 5 pivotally engaging trunnions 11 in the sleeve. The cap is fitted over the sleeve, the converging channels 13 guiding the trunnions to recesses 10, the sleeve being screwed on a thread 3 of the mouth till the cap bears upon a disc of cork or the like. To discharge the contents, the cap is rotated until the edge 6 is clear of the mouth and is swung back, the edge 7 resting on the shoulder of the tube. The inclination of the top 14 indicates the direction in which cap is to be swung. When the cap is swung back, the edges 15 of the arms will bear cam-wise against the sleeve which is thus pressed against the threads 3.

Abstract: 862,542. X-ray analysis. PHILIPS ELECTRICAL INDUSTRIES Ltd. June 3, 1957 [June 1, 1956], No. 17576/57. Class 40(3) [Also in Group XL(a)] In an apparatus for detecting the presence in a substance of elements in the second period of the Periodic Table by exposing the substance to X-rays and detecting the secondary X-radiation, the radiation is detected by an ionization chamber 19 in open communication with a chamber 15 containing the X- ray apparatus 7 and the substance 8 being examined. In the apparatus shown in Fig. 1, the secondary X-radiation is reflected by a gypsum crystal 10 through a slit 12 adjustable therewith, the softer radiation being mostly absorbed in the chamber 15, the harder radiation passing mostly through the chamber 19 and the medium radiation being mostly absorbed in the chamber 10 to produce ionization which is measured by a counter. In the apparatus shown in Fig. 4 secondary X-radiation from a source 51 is received by a counter comprising a metal cylinder 54 and an anode wire 56 carried by a bar 60 adjustable by a motor 64 which also controls the gas pressure in the apparatus.

Abstract: 644,035. Electromagnetic switches. FKG F. KESSELRING GERATEBAU AKT.- GES. July 4, 1947, Nos. 17767 and 17768. Convention dates, July 5, 1946 and July 13, 1946. [Class 38(v)] An electromagnetic switch of cartridge form has pole pieces 3, 4 arranged at the ends of the insulating tube 9 and a centrally-pivoted armature and contact member 1 adapted to bridge contact members such as 5, 6 or 17<SP>1</SP>, 18 as well as the poles 3, 4. In the form shown in Fig. 1, the member 1 is mounted on a torsion shaft 2 and the cartridge is mounted between magnetic yokes 12, 13, which when magnetized by a coil, (not shown), causes the member 1 to rotate to interrupt a circuit 1a or to make a circuit 1b. Any heat generated in the element 1 is conducted away through the fixed contacts. The tube 9 may be evacuated or filled with a gas under pressure.. In a modification, the member 1 is arranged across the tube and the conductors leading to the fixed contacts are fitted with cooling vanes. Fig. 3 shows a cartridge containing three elements 1<SP>11</SP> arranged in series between the poles 3<SP>11</SP>, 4" which also act as contacts When a magnet impulse is applied to the pole pieces the elements 1" complete a circuit I which includes a holding coil 24. In Fig. 4 a cartridge is arranged between yokes 27, 27<SP>1</SP> and immersed in a resistance liquid which completes a circuit between 27, 27<SP>1</SP> or is short-circuited by the switch in the cartridge according to whether the coil 30 is energized or not. Fig. 5 shows three switch cartridges 35, 36, 37 arranged between yokes 33, 34 magnetized by an A.C. coil 31, a short-circuited coil 32<SP>1</SP> also being provided to prevent the flux ever dropping to zero. Auxiliary yokes 47 also control auxiliary cartridges 45. Each cartridge 35, 36, 37 has a holding coil and the arrangement may be such that rise of current in the coil 32 causes successive actuation of the cartridges to cause successive control of the circuits 1 1 , 1 2 , 1 3 .

The medium becomes substantially saturated and is withdrawn from the bottom of the chamber partly through pipes 7, 8 by a fan 9, and partly through openings 4 into a. space 10 beneath the false bottom 3. The saturated medium from the space 10 passes back to the drying chamber through a number of passages 11, each containing a heater and a fan 12 which delivers the reheated medium direct to the drying chamber.

Title: Manufacture of para-aminodiphenyl and derivatives thereof
IPC: C07C209/68
Filed: 1932-06-24
Abstract: p-Aminodiphenyl and derivatives thereof are obtained by causing hydrocarbons or halogen hydrocarbons of the benzene series to act upon N-halogenacylaminocompounds of the benzene series in the presence of halides having a condensing action such as aluminium, ferric, &c., chlorides, with or without an organic diluent and with exclusion of moisture, followed by saponification of the acetylamino diphenyl compound formed.  According to examples the following N-halogenacylaminocompounds are condensed with the respective hydrocarbons or halogenated hydrocarbons in presence of aluminium chloride :--(1) N-chloroacetanilide with benzene, and chlorobenzene, the latter yielding the 4<1>-chlorocompound ; (2) N-chloroacetyl-o-toluidide with benzene ; the product of the reaction in this case gives on oxidation 3 - carboxy - 4 - acetaminodipheny saponifiable to 3-carboxy-4-aminodiphenyl ; (3) N-chloroacetyl o-ethylanilide, (4) N-chlorobenzoyl o-toluidide, (5) N-chloro-acetamino-2 : 6 - dimethylbenzene, and (6) N - chloropropionyl anilide, with benzene ; (7) N-chloroacetyl o-toluidide with toluene ; and (8) the latter amide with benzene in presence of aluminium-ferric chloride.  Other N-halogen compounds which may be employed are those of the benzene-sulphamino series. N-chlorobenzoyl-o-toluidide is obtainable by causing a hypochlorite to act upon benzoyl-o-toluidine in presence of sodium bicarbonate.

In some embodiments, this belt arrangement may be incorporated in a telescoping ball-bearing linear slide assembly, in which the belt carriage serves to maintain a ball cage member in a synchronized relative position, even in the event of ball slippage. In other embodiments, the belt arrangement may be used in conveyer mechanisms, in escalators or rolling steps, or in typewriter carriages. The elongated bodies 30, 38, and the belt 48, Fig. 1, each have friction surfaces, at least one of which is capable of being deformed into interlocking engagement with the coacting surface.
