Patent GB-565866-A (GB)
Title: Improved process for the manufacture of refractory articles
Filed: 1943-03-11
Abstract: A refractory article is produced by moulding a mixture of a powdered non-plastic refractory substance other than an oxide, or a mixture of such substances, e.g. silicon carbide, boron, boron nitride, chromium boride, nickel boride, or the like, or felspar, zircon sand, or other naturally-occurring material, with a binder consisting of a solution or suspension in an organic liquid such as turpentine of a metallic salt of stearic, palmitic, linoleic, naphthenic or other fatty or aromatic acid which decomposes on heating, and then drying and firing the plastic mass.  The metal of the salt can be the same as or different from that of the refractory substance or the principal substance.  The firing may be carried out in an oxidizing, neutral, or reducing atmosphere, whereby the organic compound can be converted into an oxide which is compatible in respect of acidity on basicity at high temperatures with the refractory substance.  Specifications 531,676 and 554,955 are referred to.

Title: Improvements in door closing and checking appliances
IPC: E05F3/10
Filed: 1939-02-07
Abstract: 512,126. Door-operating appliances. ROWLEY, Ltd., W., and SANEY, J. Feb. 7, 1939, No. 3952. [Class 65 (i)] In a door-operating appliance of the kind comprising a vertical spindle 14 connected to the door and adapted, when the door is opened to displace a thrust member under the action of a spring tending to close the door, one or two rocking levers 22 are interposed between the thrust member 18 and the spring or springs 32. In the form shown in plan in Fig. 1 for a double swing door, two levers and springs are used, and the fluid check cylinder 43 is formed as a bore in the thrust member. The spindle 14 actuates the member 18 through a pair of crank pins 16 engaging recesses 20 in the member, which carries rollers 25 engaging cam surfaces 26 on the levers 22. In another form, a single spring and lever are used, one of the rollers 25 moving over a curved surface on a fixed abutment. The check cylinder has an inlet valve 49 for the fluid and two ports 44, 47 through which the fluid escapes during the closing movement of the door. The port 44 is controlled by an adjustable needle valve 45.

Title: Improvements in or relating to continuous-rod cigarette-making machines
IPC: A24C5/18
Filed: 1949-02-14
Abstract: 662,949. Cigarette-making machines. USINES DECOUFLE. Feb. 14, 1949 [Feb. 17, 1948; Feb. 8, 1949], Nos. 3978/49 and 3979/49. Class 130 In a continuous-rod machine, excess tobacco is delivered to a belt conveyer 6 to form a tobacco sliver, such that the cross section of the sliver at those places which correspond to the dales due to irregular tobacco delivery shall be at least equal to the section of the desired average weight, and the surplus tobacco is removed from the rod-forming grooves, e.g. by a pair of rotary cutting knives 15, 16, and preferably blown back by a nozzle 24 to the hopper from which the tobacco was originally distributed on the belt. The excess may be conveyed away by endless belts towards a guide which diverts the tobacco downwards to conveyers adapted to return the tobacco to the hopper. The size of the tobacco rod is adjusted by a screw 16 through a block 17 or by adjustable side plates. Alternative methods of removing the surplus tobacco comprise leaving a narrow slot above a circular groove and providing an inclined spiked roller for removing the tobacco extending through the slot, and a pair of reciprocating co-operating clipper cutters.

Inventor: MCCAW WILLIAM FERGUSSON
IPC: B60P1/28
Filed: 1952-02-15
Abstract: 740,080. Vehicle body mountings. BOYDELL & CO., Ltd., E. Feb. 11, 1953 [Feb. 15, 1952], No. 4019/52. Class 108 (2). [Also in Group XXXI] A U-shaped superstructure-carrying auxiliary frame is secured to a tractor chassis formed by connecting together the casings of the engine, clutch, change-speed gear and driving axle and the frame comprises a transverse member b arranged behind the axle casings h and pairs of upper and lower plates c, c<SP>1</SP>, secured to the casings h and extending forwardly to be further connected to the chassis. In the preferred embodiment the forward ends of each pair of plates c, c<SP>1</SP> are interconnected by a channel member e having a notch in its base portion e<SP>1</SP> engaging a stub f bolted to the gear casing g. Each casing h is secured to its pair of plates c, c<SP>1</SP> either by a two-part clamp j, k, as shown, or the casing is shaped for direct bolting thereto. The channel-shaped transverse member b is reinforced by a stiffener b<SP>1</SP> and carries stirrups n for towing purposes. Each upper plate c supports a bracket m, the brackets carrying rails a forming parts of a superstructure, e.g. of a dumper, including a tipping bucket. The auxiliary frame is intended to relieve the chassis of at least some of the stresses due to the superstructure and to transfer the stresses to parts of the chassis better adapted to withstand them.

Title: Precision dial gauge having electrical contacts
IPC: G01B3/22
Filed: 1950-02-16
Abstract: 668,679. Linear-dimension gauges. MAHR, C. Feb. 16, 1950 [Feb. 19, 1949], No. 4047/50. Class 106 (ii). A linear-dimension dial gauge having adjustable marks for indicating the limits of a range of tolerance comprises gear means transmitting to the pointer a magnification of the movement of a gauge finger and electrical contacts on the gear means adapted to make and break circuits connected to an indicating device without affecting the movement of the pointer even when it is outside the range of the tolerance limits. In Fig. 1 a displacement of a finger A deflects a pointer 9 through intermediate members 5, 6, 7 and 8. On the member 7 are two contacts 15 fed electrically from a common source 12. Co-operating contacts 14 are mounted on spring blades 13 adjusted to desired positions by strips 19 mounted on pivoted arms 17 under the influence of springs 18 and screws 20<SP>1</SP>. When the segment 7 moves to the right or to the left a corresponding circuit is closed immediately the relevant contacts 14 and 15 touch. The spring arms 13 are so arranged that they do not prevent further movement of the segment 7 after the contacts 14 and 15 have closed. In Fig. 2 a plate 2 on which the arms 17 are pivoted is adapted to be deflected about a fulcrum 22, the screws 20<SP>1</SP> being modified to move with the plate 2. This construction enables not only the tolerance range to be varied by adjustments to the screws 20<SP>1</SP>, but also the shifting of the tolerance range relatively to the scale 10 by adjustment of a screw 21 acting on the plate 2 and by then locking the plate 2 in position by screws 23.
