Patent GB-1004021-A (GB)
Title: Gas detection apparatus
IPC: G08B17/117
Filed: 1964-04-28
Abstract: 1,004,021. Temperature alarms. E. I. DUPONT DE NEMOURS & CO. April 28, 1964 [April 29, 1963], No. 17626/64. Heading G4N. [Also in Division G1] In a photo-electric gas detector a bimetallic heat sensor 50 is connected in series with the photo-resistive detector 16, in the alarm circuit. The sensor is arranged so that at a temperature of 1350 F., its contacts open, the current to the relay coil 38 is cut off and the relay arm 40 is released to complete the circuit to the horn 44. The circuit has an A.C. supply, through an isolating transformer, with a rectifier 52 and filter 54. The continuously charged nickelcadmium storage cell 56 renders the horn operable in the event of an A.C. power failure. Failure of the neon lamp used as the source in the photo-electric system, also causes sounding of the horn.

IPC: B22C15/24
Filed: 1948-07-01
Abstract: 650,507. Core-making machines; core-boxes. WOOD, D. H., and WILSON, C. H. July 1, 1948, No. 17684. [Class 83 (i)] A core-blowing machine comprises a sand container with means for agitating the sand, for admitting air and for discharging the sand through valved pipes to one or more closed but vented core-boxes to which said pipes are connected. The container 20 has an inlet hopper with a conical closure 27, an agitator 31 rotated by a motor 39 through gearing 36, air inlets at 30 from a passage 28 supplied with compressed and valved outlets 40 leading to flexible pipes 22. One or more of these are connected at 23 to a core-box 21 which is closed, except for air vents. To ensure that sand is directed to all parts of a core-box 21, Fig. 3, more numerous vents are arranged in the end plate 41 and at 46 and the core bar 42, Fig. 7, which is supported in the holes 44, Fig. 3, is provided with a sand-deflecting plate 45 in addition to sand-retaining wires 43. Core-bars.-A core-bar for a pipe with a rightangle branch may comprise plates 50, Fig. 9, with cross-wires 53, end plates 51, supporting bars 52, and welded collars 58 which are engaged by rods 54 with cross-wires 57, end plate 55. and supporting bar 56. Specification 650,506 is referred to.

Title: Improvements in and relating to power driven vehicles
IPC: B62D61/02
Filed: 1922-06-27
Abstract: 182,471. Atlantic Akt.-Ges. f³r Automobilbau, (Assignees of Henkel, H.). June 29, 1921, [Convention date]. Spring devices.-In single-track power-driven vehicles having lateral supporting-wheels adapted to be lowered to, or raised from, the ground, the lateral wheels are adjusted in vertical position (to compensate for changes in the position of the main wheels relatively to the body as the springs weaken), by means of a tensioning-device d, in the form of a wire-strainer for example, interposed between the spring or springs a and the pivoted frame c carrying the rear wheel b. A modified tensioning-device comprises a screw and nut, the nut being flanged and guided in a stirrup under the control of a helical spring adapted to form an additional shock-absorber.
Patent GB-951690-A (GB)
Title: Improvements in, or relating to bumpers for motor vehicles
Inventor: MARCHINI PAUL PETER
IPC: B60R19/18
Filed: 1961-05-16
Abstract: 951,690. Vehicle bumpers. PLASTMANT Ltd. May 11, 1962 [May 16, 1961], No. 17768/61. Heading B7J. A vehicle bumper comprises a pair of superimposed resilient leaves 13, 14, Figs. 3 and 4, made e.g. of synthetic resinous material, the leaf 13 having parallel ribs 20 for seating in parallel grooves 21 in the leaf 14, the latter having ribs 22 seating between parallel projections 24 on elongated portions of a pair of brackets (only the bracket 11 being shown) secured to the vehicle frame. The leaves are retained on the brackets by pins 16 on the leaf 13 passing through aligned holes in the leaf 14 and brackets, the pins 16 being retained by cross-pins 17. When the bumper receives an impact in the direction F, Fig. 9, the leaves flex from the positions shown in Figs. 3 and 4 and the projections ride in the grooves or over the projections 24 as shown in Figs. 9 and 10, so that some of the impact is absorbed by such flexing and by friction. When the impact force is removed the leaves return to their normal shapes. The leaves may be reinforced by transverse ribs between the ribs 20 and further ribs extending between the transverse ribs. In other embodiments only one leaf may coact with the brackets.

C in such a manner that when not in use the tray hangs vertically against the side of the chair &c., the bracket being swung forward through 180‹ and the tray swung upwards on the bracket through 270‹ to the operative position in which it is supported horizontally by a bent or displaced portion D of the bracket. As shown the bracket comprises a single rod bent at right angles. The upper surface of the tray is hollowed for the reception of cups, plates, ash-trays, &c.
Patent GB-673639-A (GB)
Title: Process for the production of acyl derivatives of amino hydroxybenzene carboxylic acids
Inventor: GOLDBERG ALAN AUGUST
IPC: C07K1/00
Filed: 1948-07-02
Abstract: A process for the production of a salt of a 4-benzoylamidosalicylic acid having the general formula <FORM:0673639/IV (b)/1> in which X is hydrogen or a halogen atom or a nitro or carboxylic acylamido group, which comprises treating para-amino-salicylic acid or a salt thereof with a benzoyl halide carrying the substituent X in the para position in the presence of an acid acceptor.  In the preferred method the benzoyl halide, optionally dissolved in a solvent is added in portions to an aqueous solution of a water-soluble salt, such as an alkali metal salt of the para amino salicylic acid, the reaction mixture being maintained slightly alkaline by portionwise addition of alkali.  The benzoyl halide and alkali may be added substantially simultaneously. Sodium and potassium salts of the para-aminosalicylic acid and sodium and potassium hydroxides as alkalies are preferred. Alternatively the para-aminosalicylic acid is dissolved in an organic base, e.g. pyridine, and the benzoyl halide is added to the solution with simultaneous or subsequent treatment with aqueous alkali to hydrolyse any o-acyl derivative formed.  In either process the free acid may be liberated by acidification of the reaction mixture to a pH of about 3, preferably with a mineral acid.  The acylating agent may be benzoyl chloride or bromide, para-nitrobenzoyl chloride, a parahalogen benzoyl chloride such as para-chlorobenzoyl chloride or an acylamidobenzoyl halide such as para-acetamidobenzoyl chloride. In examples (1) sodium hydroxide is added to an aqueous suspension of para-aminosalicylic acid to give a neutral solution.  Acetone is added followed by nitrobenzoyl chloride in acetone and sodium hydroxide together. After stirring hydrochloric acid is added and the precipitated 4-(para-nitrobenzamido) salicylic acid is recrystallized from dilute alcohol; (2) 4-(para-chlorobenzamido) salicylic acid and the sodium salt are similarly prepared from sodium para-aminosalicylate dihydrate and para-chlorobenzoyl chloride; (3) 4-(para-acetamidobenzamido) salicylic acid and the sodium salt are prepared from paraacetamidobenzoyl chloride (prepared from p-acetamidobenzoic acid and thionyl chloride in dry ether) and sodium para-aminosalicylate dihydrate.
