Abstract: The invention comprises tetrazaindene compounds having the general formula <FORM:0814823/IV (b)/1> wherein R represents an hydroxyl group or a chlorine atom, R1 represents an alkyl or aromatic group and R2 represents hydrogen or an alkyl or aromatic group, utilizable as photographic anti-fogging agents (see Group XX) which may be prepared by condensing 3-amino-5-hydroxymethyl-1 : 2 : 4-triazole with an acyl ester of the general formula R2CO.CH(R2)COOR3 wherein R1 and R2 are as defined above and R3 represents a lower alkyl group, e.g. methyl or ethyl, whereby products are obtained in which R is a hydroxyl group, and these may be reacted with phosphoryl chloride to obtain the products in which R is a chlorine atom.  In the above formul  R1 may be, for example, methyl, phenyl or p-methoxyphenyl and R2 may be, for example, methyl, ethyl, phenyl or tolyl.  In examples: (1) amino guanidine bicarbonate is refluxed with aqueous glycollic acid in the presence of some nitric acid yielding the glycollic acid salt of 3-amino-5-hydroxy methyl-1 : 2 : 4-triazole which is reacted with ethyl acetoacetate in glacial acetic acid to give 4-hydroxy-2-hydroxymethyl - 6 - methyl - 1 : 3 : 3a : 7 - tetrazaindene; its hemihydrate is described; (2) the product of (1) is converted into the hemihydrate of the 2-chloromethyl derivative by refluxing with phosphoryl chloride; the anhydrous 2-chloromethyl compound is obtained therefrom by treatment with hydrochloric acid. Other tetrazaindenes of the above general formula are described wherein R1 represents phenyl, R2 is hydrogen and R represents OH or chlorine or wherein R1 is CH3, R2 is C2H5 and R is OH, or wherein R1 is CH3, R2 is phenyl and R is OH. Specification 619,557 is referred to.

Filed: 1976-05-05
Abstract: 1495898 Extruder for marbleized soap IDEAL SOAP CO 5 May 1976 [9 Oct 1975] 18406/76 Heading B5A A marbleized soap bar is extruded by an extruder screw 5, to different thread grooves of which a different coloured soap is supplied at respective inlets 6, 7, at least one of which is provided with a rotated obturating screw 28 which acts, during rotation of the screws 28, 5 in opposite directions, to permit entry of soap from the inlet to a groove of thread 5 to be filled whilst at least partially obturating entry to another groove supplied with soap from another inlet. The thread of screw 28 is of a pitch equal to that of the threads of screw 5, and it acts to at least partially restrict the supply to the groove of thread 5, by radial engagement therewith at a clearance.  Some intermixing of the different soaps may be permitted by the screw 28 being adjustable towards and away from the screw 5 by means of the shaft 29 which rotates the screw 28, or the land of the thread of screw 28 may be less than the width of the groove engaged, by an amount whereby at leat more than half the width of thet groove is obturated. In the embodiment, the screw or screws 28 are rotated from the shaft of screw 5 and a pair of inlets 6, 7, are provided, each supplying a different thread of a pair of threads on the screw 5. Both inlets 6, 7, Fig. 1, may be provided with a screw 28 acting on a different groove, when the threads on screw 5 extend throughout both inlets or, Fig. 3, only the downstream inlet 7 may be provided with the screw 28, when only one of the threads of screw 5 extends to the upstream inlet 6. The Fig. 1 embodiment may comprise open inlets 6, 7, or both the Fig. 1 and Fig. 3 embodiments may comprise vacuum inlets 6, 7, each supplied from a separate extruder discharging soap through a perforated plate from which it is cut by a knife rotated by the extruder screw shaft. The extruders extruding the marbleized soap comprise cooling jackets 33, and a compression chamber heated by a jacket 34, and into which the soap is discharged from the screw 5, via a perforated plate 4.

Abstract: Electrolytic or other Mn in powdered, granular or thin flake form, and low-carbon or medium-carbon ferro-manganese containing at least 60 per cent manganese, are nitrogenated to contain 2-7 per cent nitrogen.  For example, there may be produced a ferro-manganese containing 2-6 per cent nitrogen 60-85 per cent manganese, the balance iron.  Any of the above alloys may also contain chromium, and may be mixed with a binder to form briquettes for the production of stainless steel containing 21 per cent chromium, 9 per cent manganese, 4 per cent nickel, 0.4 per cent nitrogen, the balance iron, for use in high temperatures such as exhaust valves of internal combustion engines.  Manganese or ferro-manganese in solid form may be exposed to nitrogen at elevated temperature, or they may be melted in an induction furnace and have nitrogen passed therethrough.  Use may be made of commercial bottled nitrogen which has been de-oxygenated by passage through crushed ferro-silicon or ferro-aluminium.  The temperature may be 1200-2400 DEG F., preferably 1500-1900 DEG F., and the time of treatment 1/4 -5 hours, preferably 1-2 hours.

Abstract: 356,830. Gravity and inertia switches operated by tilting and impact. HENSMAN, W., 305, Wimbledon Park Road, London. June 17, 1930, No. 18495. [Class 38 (v).] A switch, specially adapted to open the ignition or other circuit of a motor vehicle should the vehicle collide or overturn, comprises two stationary spring contacts p, q, which normally engage the opposite ends of a conducting member passing through an insulating drum a, these ends being situated in grooves c at opposite sides of the drum. The pressure of the hemispherical ends r of the springs p, q in the grooves c prevents the drum a, which is mounted on a spindle d, from being moved into the dotted-line position, Fig. 1, under the action of a spring 7, excepting upon impact. The drum a also carries by means of two strips u, v, a weight t, which normally maintains the drum in the angular position shown. Should, however, the vehicle tilt beyond a certain angle, the drum a will rotate so far about its axis d that the ends r no longer engage the grooves c and the spring 7 will in this case also open the switch.

Title: Improvements in or relating to automatic wear-adjusting mechanism for brakes
IPC: F16D65/56
Filed: 1952-07-23
Abstract: 708,607. Internal shoe-drum brakes. BRISSON, L. C. July 23, 1952 [Aug. 18, 1951], No. 18699/52. Class 103 (1) The invention relates to automatic clearance adjusting devices for internal shoe-drum brakes of the type in which a threaded member 1 is actuated by a toothed gear 4 which advance it by one tooth for each application of the brake. In the device, as shown in Fig. 1, each application of the brake caused a downward movement of the member 3 which carries with it the threaded sleeve 2 and gear member 4. The pawl 8, which as shown in Fig. 3, is pivoted to a fixed part of the brake 10, is normally pressed into engagement with teeth 5 on the top face of member 4 by a spring 11. The downward movement of member 4 thus causes the pawl 8 to slip a tooth and rotate the member accordingly. In order to provide a more sensitive arrangement than heretofore the member 4 is arranged to rotate sleeve 2 by an amount corresponding to only one tooth for each full rotation of the member 4. This form of operation is obtained by coupling the member 4 and sleeve 2 by a spring pressed finger 13 which engages ratchet teeth 12 on the sleeve 2 only when the outer end of the finger 13 is engaged by a boss 15, as shown in Fig. 2, on the inner surface of the recess in the fixed brake part 10.

Carpet-sweepers.-A brush-clearer of the type indicated in Specifications 26003/13, 178,296; and 203,845, [Class 19, Brushing &c.], is provided with means for engagement with one or more diagonal, transverse, or longitudinal slots provided through, in, or below the top of the sweeper case, so that the clearer may be moved or adjusted with relation to the brush. In the construction shoyn in Figs. 1 and 3, the clearer D is secured to a bar E which is supported by means of headed screws e passed through diagonal slots F formed in the top of the sweeper case and through corresponding slots in reinforcing strips f. On reversal of the direction of rctation of the brush, the bristles engaging with the teeth of the clearer cause it to be moved diogonally corresponding to the limits of the slots. The clearer D may be pivotally connected to the bar E. The slots may be transverse or longitudinal with respect to the length of the clearer. In the latter case the clearer is adjusted by hand, one of the screws, which has an enlarged head, working in a nut on the supporting bar E so that it can be tightened to lock the clearer in position. Where only one slot is formed, as shown in Fig. 9, guides b may be provided to limit swinging of the clearer. In a further construction slotted brackets are provided on the underside of the top of the case for engagement with pins on the clearer, or on the bar carrying the clearer.
