Title: Improvements in or connected with permanent hair waving
IPC: A45D7/04
Filed: 1935-02-21
Abstract: 452,576. Hair - curling appliances. CALVETE, 1. B., 59, North Street, Clapham, London. Feb. 21, 1935, No. 5566. [Class 131.] A sachet for use in permanent waving of hair wound in tresses on curling rods includes a screen having perforate and imperforate parts so that when folded over the inner exposed face of the impregnated pad, the pad is wholly or partially screened by the perforate or imperforate part. The sachet comprises a sheet of paper a, a non- absorbent layer b and a pad of lint, felt or other, absorbent c behind which the paper is cut away to form a window c<1>. The paper is folded on the lines x so that as shown in Fig. 3 a space is left between the line x<1> and the edge e for the reception of a strip f, one part of which is perforated. The strip is movable and either end is bent over to screen the pad either wholly or partially. The screen may be secured to the sachet, and it may be located between the front part of the paper enclosure and the front face of the pad. Specification 177,995, [Class 131], is referred to.

Title: Signalling device operated by a running train
IPC: B61L29/26
Filed: 1927-02-28
Abstract: 274,379. Lehner, J. Feb. 28, 1927. No Patent granted (Sealing fee not paid). Track apparatus actuating signals other than on traino; visual outdoor signals. - A treadle-operated signal for railway crossings is operated to both the "danger" and clear" positions by a single operating rod. In the form described the successive movements of the rod step the signal arm round in one direction through 90‹, so that the arm is alternately vertical (clear) or horizontal (danger. A lever pivoted transversely to the track and at a suitable distance from the crossing carries at its free end a pulley 6 resting in the bight of a transmission rope 7. The rope passes over guide pulleys 8, 9 and is tethered at one end to the rails, &c., and at the other to the lower end of a vertically moveable signal-operating rod 11. A pair of treadle bars 2 pivoted at their outer ends, have their inner ends resting on the transverse lever, so that passage of a train over the treadle raises rod 11. A similar treadle operating rod 11 in the same way is placed at the other side of the crossing. The upper end of bar 11 has a notch which engages one or other of four pegs 18 equally spaced round the face of a disc 17 on a shaft 15 so that the disc is moved clockwise through 90‹ each time rod 11 is raised. Forward movement is limited by a pawl 21 adapted to engage one or other of four teeth 20 on a disc, the pawl being normally raised clear by a projection 24 on rod 11 resting on a pivoted weighted arm 23 linked to the pawl, but allowed to engage under action of the weight when the rod 11 is raised. Backward movement of the disc is prevented by a pawl 30 engaging the opposite faces of the teeth 20. The signal arm 16 which moves with the discs is thus moved so as to be alternately vertical (normal clear position) and horizontal, the movements occurring when a train passes the treadles on entering and leaving the crossing section of track. Movement of the signal preferably controls audible and optical signalling devices of any suitable kind.

Title: Improvements in and relating to anchor-type-escapements
IPC: G04B15/00
Filed: 1950-03-06
Abstract: 683,300. Retarding action of switches; electromagnetic switches. BRITISH THOMSON-HOUSTON CO., Ltd. March 6, 1950 [March 19, 1949]. No. 5596/50. Class 38 (v) [Also, in Groups XXVI and XXXIV] An escapement device, particularly for delaying the opening of an automatic reclosing circuit-breaker, comprises an escape wheel 9 co-operating with a pallet member 2 pivoted at 4 and connected by springs 5 to a mass member 3 also pivoted at 4. The arrangement is such that the delay is inversely proportional to the degree of overload so that the delay may be co-ordinated witn that of fuses connected in series with the circuit-breaker. In one arrangement, an opening solenoid 12 is connected in series with the circuit-breaker contacts 19, linked by a pin-and-slot 18 to a plunger 14 carrying a core 13 and ratchet teeth 15 co-operating with a ratchet wheel 16 secured to escape wheel 9. On a slight overload, the wheel 9 is rotated slowly by upward movement of plunger 14, so that the pallet member 2 and mass 3 oscillate about pivot 4 as one, thereby giving a long delay. With higher degrees of overload, however, the springs 5 cannot transmit enough force to overcome the inertia of mass 3 and they give so that the pallet member 2 oscillates more or less independently of the mass 3, thereby giving a shorter delay. Specifications 360,064 and 448,674 are referred to.

Abstract: 1415394 Electro-depositing chromium and chromium oxide PENNWALT CORP 5 Feb 1973 [3 March 1972] 5652/73 Heading C7B Cr and Cr oxide coated tin-free steel strip is produced by annealing a cold rolled steel strip, e.g. wound into a tight coil at 1150 to 1250 F for 7 to 10 hours, then electro-depositing thereon Cr and forming thereover a Cr oxide layer, e.g. in a solution of CrO 3  containing NaOH and Na2 Si F 6 ; the strip being rinsed with an aqueous medium containing (e.g. 100-2500 ppm of) a reagent, which reacts with carbonaceous deposits on the strip at the annealing temperature to form a volatile product, between cold rolling and annealing. The reagent may be colloidal S or a S-containing compound which reacts to form CS 2 , e.g. alkali or alkaline earth metal or ammonium (bi)sulphate, (bi)sulphite, thiocyanate, dithionate, thiosulphate, (poly)sulphide, or an organic (di)sulphide, thioether, sulphoxide, sulphone, sulphate ester, sulphonate or (diethyl)thiourea; or it may be an O-containing compound which reacts to form CO, e.g. alkali or alkaline earth metal oxide, hydroxide or salt decomposing to oxide at the annealing temperature, such as nitrite, borate, bicarbonate, permanganate or Ti oxalate. Prior to cold rolling, the steel (e.g. slab) may be hot rolled, pickled in dilute H 2 SO 4  or HCl and rinsed; after cold rolling, the strip may be cleaned in hot aqueous alkaline solution, rinsed and scrubbed, prior to rinsing with the aqueous reagent. After annealing, the strip may be temper or cold rolled, again cleaned, pickled in dilute H 2  SO 4  and rinsed.

Patent GB-573573-A (GB)
Title: Improvements in or relating to the manufacture of unsaturated aldehydes and ketones
IPC: C07C45/75
Filed: 1942-05-07
Abstract: Alpha-unsaturated aldehydes and ketones are produced by reacting formaldehyde with another aldehyde or ketone in the vapour phase by feeding to the reactant vapours at or near the entrance to a long reaction chamber a powdered dehydrating catalyst which becomes suspended in the vapours and on leaving the reaction chamber is separated and recycled or revivified.  In an example, acrolein, together with a small quantity of crotonaldehyde is produced by treating a mixture of acetaldehyde and formaldehyde vapours with a suspended catalyst consisting of sodium silicate in silica gel, a part of which after separation from the reaction vapours is recycled and a part revivified by heating in air at 500-600 DEG  C.  The process may be used for the production of higher unsaturated aldehydes from formaldehyde and higher aldehydes and of unsaturated ketones from formaldehyde and saturated ketones.  Specifications 13549/89, [Class 55], 23045/10, 304,251, [both in Class 1 (i)], 497,757, 513,772 and 544,188 are referred to.
