Abstract: 262,627. Heath, F. G. Feb. 11, 1926. Trouser stretchers. - A trouserstretcher of the insertible type comprises two side-members having sharp outer edges and connected and pressed apart by four springs of strip formation which are secured one at or near each end of the two sidemembers and curve inwardly towards the centre of the stretcher, their inner ends being connected in pairs in such a manner that the one pair slides or moves relatively to the other. As shown, Figs. 1 and 3, the inner ends 18 of the spring 12 at one end of the stretcher are associated with a sleeve 21 within which the inner ends 17 of the springs 12 at the other end of the stretcher slide as the side-members 10 are moved towards or away from each other. The members 10 are formed from wood of triangular section, the base 11 of the triangle being relatively short and forming a flat inner edge to the sidemember. The inner ends 17 of the springs 12 are connected together by rivets 20, and the inner ends 18 of the other springs 13 are secured within the end of the square-sectioned sleeve 21. Figs. 4 and 6 show a stretcher with hinged sidemembers which allow it to be folded for packing. The hinged joint is formed by a link 30 perforated at each end and embedded in a slot 31 in the ends of the two parts 25 of the side-members. Pivot-pins 32 driven into the flat edges of the side-members connect the link 32 to the parts 25. Sliding sleeves 35 are provided to cover the joints and render the side-members rigid when required. The ends of the parts 25 on which the sleeves slide are reduced at 36 to enable the sleeves to lie flush with the remaining part of the side-members, the reduced part being extended at 37 on one of each. pair of plates 25 to allow the sleeve to be moved clear of the joint. When it is desired to fold the stretcher, the inner end 17 of the springs 12 is pulled out of the sleeve 21.

Title: A new deserpine diol and process for its manufacture
IPC: A61K8/49
Filed: 1956-02-09
Abstract: The invention comprises deserpidine-diol and salts and esters thereof; the diol is made by reducing to a methylol group the carboxylic group in deserpidic acid or its esters or O-acylated derivatives (see Specification 809,913) or its lactone (see Specification 818,896).  The diol may then be subsequently esterified with aliphatic, aromatic, araliphatic or heterocyclic carboxylic acids or with sulphonic acids.  The products form salts with acids such as hydrohalic, sulphuric, nitric, phosphoric, alkanesulphonic, isethionic, alkylsulphuric, acetic, oxalic, citric and tartaric.  The esters may be hydrolysed back to the diol.  By oxidation with lead tetra-acetate the corresponding tetradehydro compounds are formed. Examples are given of the reduction of deserpidine (see Specification 809,912) and of deserpidic acid lactone with lithium aluminium hydride and acetylation of the diol with acetic anhydride.ALSO:Deserpidine-diol (made by reduction of deserpidic acid-see Specification 809,913), its esters and the corresponding tetra-dehydro compounds are used as ingredients of sunscreen compositions.  The diol or a salt thereof can be incorporated into a hydrophilic ointment with a glycol (e.g. propylene glycol), a higher alcohol (e.g. stearyl) and petroleum jelly.  The salts of the tetra-dehydro compounds can be used in solution in 70 per cent alcohol.  Specification 809,912 also is referred to.

Title: Improvements in or relating to electrical switching devices
Inventor: FORREST ROBERT HENRY
IPC: H03K17/60
Filed: 1967-01-27
Abstract: 1,206,631. Integrated circuits; arc preventing in switches. MINISTER OF TECHNOLOGY. 16 Jan., 1968 [27 Jan., 1967], No. 4157/67. Headings H1K and H1N. [Also in Division H3] The specification discloses a switching circuit T1, T2 (see Division H3) which may be formed as an integrated circuit and can be used for arc suppression. As shown the transistors T1, T2 are off and are turned on by closing switch S1a, which may be electronic. The switch contacts S1b then close so as to take over the load current from T1, T2. When the load current is to be switched off the switch S1b is opened and the contacts of switch S1a remain closed for a short time so that T1, T2 again turn on to reduce arcing. This may be further reduced by connecting a capacitor in parallel with the contacts S1b. Also a diode (D1, Fig. 5, Provisional Specification not shown), may be connected betweentheload and the emitter of T2 so that when S1a only is closed the load current flows via the diode (D1) but when S1b also is closed the diode (D1) becomes reverse biased and a standby current is drawn by T1, T2 so as to enable T1 and T2 to be more quickly driven into their ON states. In an integrated circuit (Fig. 6, Complete Specification), the transistors T1 and T2 are constructed as one unit having four electrodes and four layers, the third layer being divided into two parts 3a, 3b by an extension of the second layer 2 by an insulating barrier, or by a gap or slot cut through the third layer. The unit may be constructed so that the external resistors R2, R3 are unnecessary or alternatively appropriate resistors may be incorporated in, or deposited on the unit. It may be necessary to inject more base current into the transistors by connecting a resistor between the emitter 5 of T1 and the base 7a of T2.

Void [Abridged as open to inspection under Sect. 91 of the Acts, Feb. 20, 1932]. [Class 106 (i).] The Specification describes a method of correcting the coordinates b, alpha, of a target C as observed at a point A so that they may be used for laying a gun situated at a point B. The required corrections c, gamma, are shown to be given approximately by the relations :- where a is the distance AB and K is a constant. A diagram for facilitating the solution of these equations is shown in Fig. 3. The distances a are marked along the base g h of a semicircle the circumference of which is graduated angularly with values of alpha + K sin alpha. In use, a radius (e.g. 0-7) is drawn to the angular graduation corresponding to the known value of alpha, the known distance a= e f = o u is set off along 0-7 and the perpendicular from u to e h enables the value of c to be read on the scale e h. To determine sin gamma, the diagram also comprises a square the side q of which is marked to represent b + c, the side r to represent a, the side O to represent sin alpha and the side l to represent sin gamma. The value b + c is set on the scale q and sin alpha on O and a line intersecting the diagonal at v is drawn. The value a is set on r and the point joined to v and continued to l to give the value of sin y.

Title: Electric gaseous discharge waveguide switching device
IPC: H01J17/04
Filed: 1953-02-18
Abstract: 749,755. High-frequency discharge apparatus. STANDARD TELEPHONES & CABLES, Ltd. Feb. 18, 1953 [Feb. 18, 1952], No. 4536/53. Class 39 (1). [Also in Group XL (b)] A wide-band ultra-high-frequency switching device comprises a number of discharge tubes each traversing a resonant structure within a waveguide. The structures comprise inductive irises 4, 5, Fig. 3, and one or two capacitative posts 6, 7 arranged in the same plane. Passing through each post or pair of posts is a discharge tube 10 comprising a cathode 11 and an anode 12. Isolating resistances connecting the anodes 12 to earth ensure that all the tubes, which are connected in parallel to the same source, fire at the same time. The tubes contain rare gases, i.e. xenon or argon, at a pressure of 10 mm. Hg. to which may be added small amounts (less than 0.1 per cent) of water vapour in order to decrease the de-ionization time. Power is derived from a high-voltage D.C. or A.C. (including R.F.) source. A keepalive voltage is applied to the tubes or, for the same purpose, the tubes may contain a radioactive or photo-emissive internal source. The electron density at the point where the tubes intersect the guide may be increased by decreasing the internal diameter at this point or by providing at the required point in each tube an axial rod 22, Fig. 3, of dielectric material. This rod may be supported by the anode structure. In order to obtain greater interaction between the electromagnetic energy and the gas discharge the diameter of the tubes 24 may be increased as shown in Fig. 4a. In the construction of Fig. 5, a circular waveguide 33 having segmental iris members 35 and posts 34 is traversed several times by a discharge tube 38 of serpentine form which passes through the posts 34. A modified form of tube, Fig. 7, has a gas reservoir 40 with two limbs 41, 42 and two pairs of electrodes 45, 48.
