Abstract: 148,299. Federal Tin Co., (Assignees of Cook, J. J., and Cook, C. H.). Nov. 1, 1915, [Convention date]. Clips, band.-In a clip for hose pipes &c. a band 15, one end of which is bent to form a support 17 and the other end actuated to form a tongue 16, has, eyeleted to it at 25, a drawing-strap 23, the end of which is rolled upon itself to form a coil 24, which serves as a nut for the clamping-screw 19. The support 17 is bent at right-angles to provide a guard 22. In modifications the support 17 may be coiled backwardly and the strap 23 riveted to the band, or the strap, with one or both ends coiled, may pass around the band, or the strap and coil 24 may be bent up from a stampedcut portion of the tongue. In the modification shown in Fig. 10, the band 15 is provided with a relatively long tongue 16<a> terminating in a drawing-strap 23b of reduced width, which passes through an opening 33 in the band and lies flat against the outer face of the band, its free end being provided with a coil 24.

Patent GB-779474-A (GB)
Title: Method of preparing silicon nitride articles by slip casting
IPC: C22C32/00
Filed: 1955-07-13
Abstract: Articles are cast from silicon or silicon nitride or a mixture of both by a method in which a suspension of the powdered substance is formed in a suitable medium. e.g. water, a peptizing agent is added to adjust the pH of the slip to between 7,5 and 10, the slip is poured into a mould and the cast article is removed therefrom.  The article is then nitrided by heating it in nitrogen, preferably at a temperature of 1175 DEG C. followed by 1300 DEG C.  Silicon must be comminuted to a particle size of not more than 5 microns, 3 microns being a preferable maximum, and should be commercially pure (97 per cent), and the specific gravity of the aqueous suspension should be as high as possible, i.e. the silicon content should be 60 per cent to 70 per cent by weight. The peptizing agent renders the slip sufficiently fluid for pouring and may be added either before or after the powder is introduced into the suspension medium, the quantity ranging from 0,01 per cent to 1 per cent by weight of the medium.  Suitable peptizing agents to give the above pH range are monoethanolamine, sodium hexametaphosphate and sodium pyrophosphate. The particle size for silicon nitride is 100-325 mesh.  For bonding purposes a minimum of 1 per cent silicon, of 5 or less micron particle size, should be added to the suspension.  Three examples, specifying proportions of ingredients by weight, are given of making castings from slip of silicon or silicon metal.

Abstract: 351,751. Cooling meat, fish, &c. DEUTSCHE WERKE KIEL AKT.-GES., 114, Werftstrasse, and SOMMER, P., 39, Lubecker-Chausee, Kiel, Germany. July 7, 1930, No. 20561. [Class 29.] Fish &c. to be frozen is packed into containers 11 adapted to be inserted in the compartments of a frame 12 rotated in a bath of cold circulating brine by the pressure of the brine on vanes 31 carried by the frame. In the case of a fishing-vessel, the fish is charged into bunkers 37, Fig. 8, from which it passes on to a removable shoot 25 and is charged into the containers which are removed from and replaced in the frame as it rotates in a step-by-step manner under the control of a pawl which engages with stops on the frame. After freezing, the fish is emptied from the containers on to a shoot 26 which directs it on to a perforated conveyer 41, Fig. 6, which passes through a water-spraying chamber 42 in which the frozen fish is rinsed and becomes coated with ice. After rinsing, the fish is discharged through shoots 45 into trucks 47. The brine is circulated through the bath by a pump 29. The bath and the bunkers are cooled by refrigerating coils.
Patent GB-597125-A (GB)
Title: Improvements in and relating to inertia starters for engines
IPC: F02N5/04
Filed: 1945-08-10
Abstract: 597,125. Inertia starters. AIR-EQUIPEMENT. Aug. 10, 1945, No. 20573. Convention date, Feb. 10, 1944. [Class 7 (v)] An inertia starter for engines of the kind in which a pinion 22 is slidable into mesh with an engine gear 23 has the inertia flywheel 1 arranged to drive a gear ring connected through a resilient torque limiting coupling 14 with an axially fixed sleeve 17 provided with clutch teeth 19 coacting with a clutch member 20 on the pinion shaft 21. A torque limiting clutch 25 and free wheel 24 connect shaft 21 to the pinion. The flywheel is driven through step-up gearing 2-9 from a crank-receiving shaft 10. After speeding up the flywheel the shaft 21 is moved by a lever 28 against a spring 27 thus first engaging the pinion with the gear teeth and then engaging the clutch parts 19-20 to impart rotation. When the engine starts, the free-wheel allows the pinion to overrun. In a modification, Fig. 2, a spring 37 is arranged between the sleeve 27 and clutch part 20 and a friction washer is located at 39 so that a small frictional torque is imparted to the pinion shaft 21, thus facilitating engagement of the pinion 22 with the engine gear. In a further modification the clutch part 20 is splined on its shaft and is held back against spring pressure by a pawl until the pinion is fully engaged. At this point the part 20 is released and snaps into engagement with the other clutch part 19.
Patent GB-611219-A (GB)
Title: Automatic alarm signalling system
IPC: H04L15/26
Filed: 1945-08-10
Abstract: 611,219. Electric selective signalling systems. STANDARD TELEPHONES & CABLES, Ltd. Aug. 10, 1945, No. 20577. Convention date, Aug. 15, 1944. [Class 40 (i)]. An automatic alarm device responsive to a predetermined signal comprises a contact controlling device operating contacts at regular intervals and a signal repeating circuit, so that when the contact controlling device is in synchronism with the actuation of the signal repeating circuit pulses are produced which are applied to a counter to actuate an alarm after the production of a predetermined consecutive number of pulses. The invention is described with reference to an alarm signal consisting of a long pulse of 4 seconds duration followed by a series of short pulses occuring at a frequency of two per second. The received signals are applied to relay 1 to operate contacts 8, 9, 10, 11 and the long signal energizes magnet 3 to pull over spring-arm 4 which completes a circuit over contacts 15, 16 and 8 for relay 20 which steps on arm 6. On the cessation of the long signal, spring-arm 4 vibrates at a frequency of two per second, so that the short signals close contacts 8 when contacts 15, 16 are closed to step on the arm 6. If signals are received when contacts 15, 17 are closed to step on the arm 6. If signals are received when contacts 15, 17 are closed, relay 21 is energized over contacts 10 to return the arm 6 to its starting point. Thus only the alarm signal can step arm 6 to contact 19, when relay 22 is actuated to give the alarm and lockup over contacts 23. The alarm signal is preferably developed by a similar vibrating relay, Fig. 3 (not shown).
