Abstract: 1,147,104. Brick panels. WESTBRICKS PRODUCTS Ltd. 15 Feb., 1968 [16 Feb., 1967], No. 7380/67. Heading B5A. Brick panels are manufactured by arranging the bricks on a horizontal bed being part of a mould, clamping the bricks to hold them in position, filling the spaces in between with mortar and raising the bed to a vertical or inclined position after setting and removal of clamping pressure. The mould 11, Fig. 1, may comprise the bed 12 on a table of reinforced concrete, the bed 12 being pivoted at 13 to the table and a frame assembly of channel section girders 21, 22, secured to bed 12 by swing bolts (23, Fig. 2, not shown). The bricks 14 are located by structure 15 comprising primary guide elements 60 to determine the rows of bricks and secondary guide elements 62 interfitting with the primary elements to determine the brick positions relative to the mould 11 rather than to adjacent bricks. The clamping assembly 16 comprises cross members 71, 72 and members 73 supporting damping pads 74 bearing resilient material. Bed 12 is also covered with resilient material but harder than that on the pads so that any irregularities occur in the upper surface of the panel. Reinforcing members may be inserted in the mould, which may be vibrated while being filled with mortar e.g. by units 90, 91 causing vibrations in both horizontal and vertical planes. Arms (17, Fig. 3, not shown) pivoted to the bed 12 and carrying a ratchet pin (42) engage in racks (18) to support the bed in the inclined or vertical position.

Title: Process for modifying drying oil-modified alkyd resins
Inventor: BARRETT KEITH EDWIN JAMES
IPC: C08G63/91
Filed: 1965-02-22
Abstract: An alkyd resin which contains an unsaturated drying oil radical having two or more ethylenically unsaturated groups is treated with free oxygen-containing gas to introduce oxygen containing groups therein and a polymerizable ethylenically unsaturated monomer which readily homopolymerizes in the presence of free radicals and a metal drier salt are either present during or added concurrently with or subsequent to, the treatment, free radicals being thereby generated on the oxidized alkyd resin and the monomer being polymerized therewith. The alkyd resin may be prepared from phthalic anhydride and pentaerythritol and may be modified with linseed or soya bean oil. The monomer may be an ester or amide of acrylic or methacrylic acid, styrene or vinyl toluene.  The alkyd resin in solution in white spirit with the monomer, e.g. methyl or lauryl methacrylate, may be treated with oxygen in the presence of cobalt octoate, and dipentene may be added to the treated resin solution as a storage stabilizer.

Title: Improvements in or relating to machines for treating the surfaces of containers
IPC: B41F17/18
Filed: 1949-03-22
Abstract: 681,471. Printing &c. on curved surfaces. TIMSONS, Ltd., and TIMSON, E. A. March 21, 1950 [March 22, 1949], No. 7760/49. Class 100 (ii). In a machine for printing, embossing or otherwise marking the curved surfaces of containers, e.g. rigid or collapsable metal, paper, card or plastic tubes for pastes &c. the containers are presented in turn to a printing &c. means by mandrels held by chucks equi-spaced around an intermittently rotated turret and rotatable therein about axes parallel to the turret axis, and are then engaged by a doffing device movable towards and away from the turret in timed relation therewith to effect partial or complete withdrawal. Fig. 1 shows a turret 5 in course of a 60 degrees step of clockwise rotation (produced, according to the Provisional Specification, by Geneva mechanism); at a station between 4<SP>2</SP> and 4<SP>3</SP> containers 3 are manually (or automatically according to the Provisional Specification) loaded onto mandrels 4 carried by chucks 6; at the station before 4' they are printed by the plate 2 of a rotary printing machine 1, and at the station between 4' and 4' they are removed by a device 8. This comprises a rubber &c. suction nozzle 43 on a carriage 9, Fig. 2, reciprocated along fixed rods 10 by a chain 13 passing round sprockets 16 (adjustable for chain tensioning) and 15 (driven by a quadrant gear 25 pivoted at 26 and oscillated by a connection 29, 30 from a crank disc 31, Fig. 1, driven in synchronism with the movements of the turret 5). The nozzle 43 is longitudinally adjustable on a block 47, which is secured to a tubular shaft mounted transversely in the carriage 9 and serving, with rubber &c. tubes 40, 42, as a conduit to connect a vacuum source to the nozzle 43; towards the end of the withdrawal movement of the carriage 9 from the turret 5 this tubular shaft is rotated (against a spring loading according to the Provisional Specification) through 90 degrees by engagement of a forked arm 49 thereon with a fixed pin 51, thus bringing the withdrawn container 3 into a vertical position, Fig. 5, at which point a fixed rod 60 opens a spring-loaded flap valve 55 on the tubular shaft to break the vacuum whereby the container 3 is released onto a belt, chain or other conveyer. This conveyer may be in the form of a rotary table 63 with receiving pins 64, Figs. 1 and 2; as shown the table is intermittently rotated in synchronism with the movements of the turret 5 by a ratchet and pawl 65, 66 connected by a rod 67 to the quadrant gear 25.

The condensing agent may be an alkali or sodium sulphite or bisulphite, the last-named producing an alkaline medium by combination with aldehyde. Examples describe the production of butanol-1-one-3 from acetone and formaldehyde and 2-methylbutanol-1-one-3 from methyl ethyl ketone and formaldehyde.
Patent GB-293083-A (GB)
Title: Improvements in or relating to electro-magnetic relays or indicating instruments
IPC: H01H51/22
Filed: 1927-03-22
Abstract: 293,083. General Electric Co., Ltd., and Angold, A. E., March 22, 1927. Drawings to Specification. Detecting and indicating faults.- In a directcurrent relay or indicating instrument having an armature which is adapted to be moved by differentially acting forces caused by currents flowing in conductors, the current flowing in one conductor or set of conductors is arranged to give the armature magnetic polarity in the same sense as that produced by the current flowing in the other conductor or set of conductors. As shown in Figs. 1 and 2 of Specification 293,082 currents are arranged to flow in similar directions along bus-bars 1, 2. Supported at the sides of the bus-bars are two pairs of pivotally mounted permanent magnets 15, 16 and 17, 18 carried on frames 13, 14 the frames being carried on knife-edge trunnions 30 suspended by springs 31, each frame being balanced by weights 23 and the adjacent ends of the frame being connected by a link 26. The adjacent poles of the pairs of permanent magnets are arranged so that common flux flows through magnetic 15, 16 and through magnets 17, 18. Thus when the currents in bus-bars 1, 2 are equal the forces at opposite ends of the magnets are equal and opposite and no movement of the armature occurs but with unequal currents the frames are rotated in opposite senses and operate relay contacts or give an indication of the lack of balance. To make this action as powerful as possible, the bus-bars are shaped to give a small air gap between the adjacent magnet poles with a comparatively high current density at these points. and mica plates 19, 20 are mounted at their sides to prevent contact between the magnets and busbars. Recesses 5, 6 are provided in the bus-bars to permit of movement of the controlled contact elements (not shown). The flux due to the currents flowing in the bus-bars in each case assists the flux of the permanent magnets and in view of the added flux due to the currents flowing the relay is more sensitive to small differences of current when large currents are flowing in the bus-bars than with small currents, although the permanent magnetism is such as to ensure the necessary sensitivity in the latter case. The arrangement of the magnets give the armature astatic characteristics and in view of the mechanical arrangement of the frames 13, 14 and their associated parts the relay is unaffected by rolling or pitching motion to which the relay may be subjected in the manner described in Specification 293,082.

Title: Electric cut-out or fuse for fire alarm purposes
IPC: G08B17/06
Filed: 1949-03-24
Abstract: 658,549. Thermal switches. EKMAN, O. I. H. March 24, 1949, No. 8023. [Class 38(v)] A fire-alarm cutout (shown inverted in the drawing) comprises two pairs of tongues 8 respectively connected to two wires of the alarm circuit, each pair being normally bridged by U-shaped members 3 connected to the tongues by fusible joints 7. An insulating bar 4 fixed at 6. to the bridges 3 and extending therethrough is urged away from the insulating base 12 by the closed end of an insulating sleeve 9 slidable in a recess 22 in the base and housing . a pair of compression springs 10 arranged one inside the other. A pin 1 fixed to the end of the sleeve 9 extends through a clearance hole in bar 4 to the exterior of an insulating housing having openings bounded by arms 5; since the sleeve 9 does not reach to the bottom of the recess 22 the force of the springs 10 can be checked or measured by depressing the pin 1 thereby improving the reliability of the fire-alarm system. On melting of the joints 7 the two circuits are interrupted by the springs 10 assisted by the weight of the bar 4 and the pin 1 extends further through the housing to indicate the operation of the cutout. Rapid melting of the joints is ensured by using a small amount of fusible metal, by the provision of heat absorbing extensions 21 of good heat conductivity on the bridges 3, and by minimizing heat leakage from the joints by making the electrical connections thereto of small cross-sectional area and of metal having poor heat transmission qualities. A suitable joint 7 is formed by making co-operating slits in the extremities of the parts 3, 8, the ends of which are bent over and the openings filled with metal, Figs. 4, 5 (not shown).
