[Class 3 (ii).] A collapsable advertising model comprises a tubular part having a plurality of vertical hinged walls, and a top part hinged at the top of one of the said walls and adapted to hold the device in the open position or to lie between the walls when the device is collapsed. As shown, a device simulating a pile of packets d comprises stepped front and back members a, e joined by vertical strips f. The device is held open by means of a member l which is shaped to correspond with the members a, e and the horizontal stepped edges of which are connected by rectangular pieces m to the corresponding edges b of the member a, the members m thus simulating the tops of the packets. When not in use, the member l is moved downwardly so that the parts m pivot about the edges b until they, together with the member l, lie flat against the member a, when the whole device may be collapsed. The hinged parts are formed integrally where possible, but may be suitably joined. In a modification, the parts m lie slightly below the horizontal edges of the front and back members, so that shallow trays are formed in which goods may be displayed. In a simple form where only one member m is employed, a stop may be provided to limit its upward movement. The device may take any polygonal form provided it is capable of folding flat. Reference has been directed by the Comptroller to Specifications 23849/07, [Class 3, Advertising &c.], 340,685 and 366,830.

Title: Analog keyed phase transmitter and system
IPC: G08C19/12
Filed: 1965-08-20
Abstract: 1,123,621. Electric selective signalling. ROBERTSHAW CONTROLS CO. 20 Aug., 1965 [21 Aug., 1964], No. 35870/65. Heading G4H. The magnitude and direction of changes in the rotation of a shaft or in a voltage are signalled by transmitting a sequence of equispaced phases, there being one phase change for each increment of magnitude and the direction of change of magnitude determining the direction of the phase change. In a first embodiment, temperature or pressure changes cause rotation of a shaft which moves an arm over spaced contacts. The contacts are in groups of three contacts, corresponding contacts in each group being fed by phases 120 degrees apart so that a repeated sequence of three phases is transmitted as the arm moves over the contacts. At the receiver each shift in phase produces a pulse of sign dependent on the direction of phase change. The pulses feed an integrator which may control the positioning of a shaft. In a second embodiment, an input electric continuously variable signal controls a variable frequency oscillator. A discriminator pulses each time the frequency changes by a given amount, the sign of the pulse depending on the direction of the change. A counter counts the pulses and controls in cyclic sequence three gates fed by equi-spaced phases. The gates' outputs are transmitted to a receiver similar to that described above.

Patent GB-414077-A (GB)
Title: Improvements in and relating to soaps and the like
IPC: C11D9/30
Filed: 1932-12-21
Abstract: Soaps are mixed with alkylolamine salts of acids other than soap forming acids and their sulphonation products, to stabilize the soap and to improve the lathering properties.  Preferably the salts of mono-, di- or tri-alkylolamines with acids containing homo- or hetero cyclic groups are employed.  The acids may contain substituted or unsubstituted mono- or poly cyclic groups, and the hydrogen atoms of the side chain or nucleus may be replaced by nitro, amino, acidic, halogen, alkyl or hydroxyl groups; the latter may be further substituted with acyl aryl or alkyl groups. Acids having a carboxylic or sulphonated carboxylic group connected through an unsaturated side chain with the nucleus may also be used.  Specified acids include: Benzoic, toluic, chlor or nitrobenzoic, anthranilic, salicylic acid or derivative thereof, gallic, tannic, phenyl acetic, hydrocinnamic, phthalic, mellitic, pyromucic, indoxylic, or thiophene sulphonic acids.  The alkylolamine salts may be added to the soap or formed in situ.  In examples, commercial tri-ethanolamine is warmed with naphthalene sulphonic, benzoic phthalic or salicylic acid or potassium hydrogen phthalate to form a semi-solid or syrupy mass which is then preferably dissolved in a small amount of water containing glycerine and incorporated in soap.  The salt may be mixed with sodium hydroxide or potassium carbonate and boric acid, and added after crutching or boiling the soap, or incorporated with soap flakes during the milling process.ALSO:Alkylolamines are warmed with acids containing homo- or hetero cyclic groups to form salts thereof. Mono-, di- or tri-alkylolamines such as commercial triethanolamine may be treated.  The acids may contain substituted or unsubstituted mono- or polycyclic groups, and the hydrogen atoms of the side chains or nucleus may be replaced by nitro, amino, acidic, halogen, alkyl or hydroxy groups; the latter may be further substituted by alkyl, aryl or acyl groups.  Acids having a carboxylic or sulphonated carboxylic group connected through an unsaturated side chain with the nucleus may also be used. Suitable acids are benzoic, toluic, chlor - or nitro - benzoic, anthranilic, salicylic, acetyl salicylic, gallic, tannic, phenyl acetic, hydrocinnamic, phthalic, mellitic, pyromucic, indoxylic or thiophene sulphonic acids.  For example, commercial triethanolamine is warmed to about 80 DEG  C. with naphthalene sulphonic, benzoic or salicylic acid or potassium hydrogen phthalate to form salts which are syrupy liquids or semi-solid products.
Patent GB-800170-A (GB)
Title: Production of cycloheximide by fermentation
IPC: C07D211/88
Filed: 1956-11-27
Abstract: Cycloheximide is produced in high yield by culturing a cycloheximide-producing strain of Streptomyces griseus in an aqueous medium containing soybean meal, glucose and potassium dihydrogen phosphate in the proportions of at least 14 grms. of soybean meal per litre, 0.15 to 0.25 grms. of potassium dihydrogen phosphate per litre and about four parts of glucose for each part of soybean meal.  The temperature of cultivation is 22 DEG  to 26 DEG  C. and preferably 24 DEG  C. and fermentation is continued until the cycloheximide reaches at least 1000 micrograms per millilitre. Preferably the medium also contains per litre, 5 to 10 grms. of calcium carbonate (buffer), 2.5 to 7.5 grms. of ammonium sulphate, 1 to 5 grms. brewer's yeast (source of vitamins and growth factors) and 2 to 6 grms. sodium chloride.  A preferred method of recovering cycloheximide is by acidifying the culture medium to pH 3.5 to 5.5 with, e.g., sulphuric acid, clarifying, extracting the clarified beer with methylene chloride, decolorizing, concentrating it from 20 to 40 fold, decolorizing the concentrate with, e.g., carbon, further concentrating, adding amyl acetate, removing the methylene chloride at below 70 DEG  C. and crystallizing the cycloheximide from the amyl acetate solution.  The methods of recovery described in Specifications 639,943 and 644,919 also may be used.

Filed: 1971-08-02
Abstract: 1346476 Boron trifluoride; phosphorus trifluoride USS ENGINEERS & CONSULTANTS Inc 2 Aug 1971 [31 July 1970] 36285/71 Heading C1A Boron trifluoride or phosphorus trifluoride is produced by reacting boric acid or phosphorous acid with particles of an alkaline earth metal fluorosulphonate fluoride at an elevated temperature and at atmospheric pressure or above while excluding moisture. It is preferred that the particle size of the reactants should be less than size 40 mesh (U.S. Standard). The reaction temperature should be between 50‹ and 350‹ C. In place of the alkaline earth metal fluorosulphonate fluoride, an equimolar mixture of the metal fluoride and the metal fluorosulphonate may be used. When preparing BF 3 , the product begins to be evolved at 50‹ C.; a 1 : 3 molar ratio of reactants gives the best results. In the case of PF 3 , the reaction temperature should be below 150‹ C. and the phosphorous acid injected as a melt into an agitated bed of the fluorosulphonate fluoride. The HF by-product may be separated in the case of PF 3  production by adsorption on pelletized sodium fluoride. It may be separated conventionally from BF 3  or the HF/BF 3  mixture may be used as it is as a catalyst.

Title: Improvements in damping devices for railway and like vehicles fitted with central buffer couplings
IPC: B61G11/04
Filed: 1932-12-29
Abstract: 392,856. Railway &c. vehicle bogies and buffers. KRUPP AKT.-GES., F., Essen, Germany. Dec. 29, 1932, Nos. 36759 and 36760. Convention dates, Feb. 6 and Feb. 27. [Classes 103 (v) and 103 (vi).] In railway &c. vehicles fitted with central buffer couplings, relative movement between adjacent vehicles vertically and laterally and also by rocking about an horizontal longitudinal axis is resisted by the provision of damping devices in the form of light spring buffers, which have contact surfaces interengaging for the purpose specified, but which absorb a very small proportion of the buffing stresses. In the construction shown in Fig. 3, the dampers C are slidingly mounted in relation to casings B supported at the sides of the vehicles at the higher level than the headstocks A. The faces c<1> of an opposed pair of dampers are respectively convex and concave and are pressed into contact by springs J, each of which abuts against a pivoted plate Hand an adjustable plate e<2> and surrounds a sliding rod E linked by a pivoted rod D to the damper face. At the junction of the rods D, E is fitted a roller F designed to roll on a guide surface b<1> under buffing shocks, but normally to rest in a recess b<2>. By this arrangement the inclination of the spring alters during its compression so that the resultant resistance of the dampers undergoes little variation. In a modification, Figs. 6 and 7, the dampers or buffers M are centrally mounted in pivoted casings L directly above the couplings R, and opposed dampers have co-operating ribs m<4> and ribs m<3> for resisting relative movement of the adjacent vehicles. Each damper is, however, connected by two pivots m<1> to the spring-pressed rods N, so that the dampers can swivel about a vertical axis when the coaches traverse a curve while the pressure of the springs P tends to centralize the coaches as they again reach a straight portion of the track. In this construction the casings L may constitute a gangway platform between the two adjacent vehicles.
