Patent GB-181415-A (GB)
Abstract: 181,415. Dennett, R. J. Feb. 4, 1921. Zeroizing - mechanism; transfer-mechanism. -In fare-registeringmechanism employing transfer pinions of the alternately long and short teeth type, the raising of the flag carries the pinions out of gear with the fare drums and into engagement with spring-controlled guide surfaces which retain the pinions against movements and so ensure their correct subsequent re-engagement with the drums. Except when fares are being registered, a non-return pawl engages each fare drum to prevent any forward movement. The transfer pinions 14 are mounted upon a spring- depressed lever 19 pivoted at 20 and adapted to be raised by engagement of a projection 25 on the flag spindle 26 when this is set to " free." Adjacent to each pinion is a pivoted spring-controlled lever 27 having a cam edge 33 to receive and retain the transfer pinion when out of gear. When the lever 19 is lowered its nose 32 moves the lever 27 clear of the pinion. A pawl 35<a> for each drum is controlled by a bar 41 on the lever 19 so that when the flag is raised the pawl engages its drum and prevents any forward movement.

Abstract: 740,245. Gripping devices for handling bottles; manifold arrangements. HOPKINS & SONS, Ltd., G. Oct. 19, 1953 [July 18, 1952], No. 18240/52. Class 78 (4). When a spring-loaded plunger 25, Fig. 1, on a device for lifting a bottle is depressed by engagement with an abutment it forces the bottle out of spring gripping fingers 18 sprung over its neck. The plunger 25 slides within a tubular guide 8 and the fingers 18 are carried by a tubular slide 7 surrounding the slide 8 and urged outwardly from a tubular housing 6 by a spring 20. A number of the devices is preferably arranged on a platen 15 to engage all the bottles in a crate simultaneously so that the device may be employed in a bottle uncrating machine such as that described in Specification 740,244 to which the Specification refers; the mounting of the slide 7 then permits the devices to engage bottles of differing heights. The gripping members are secured in slots 30, Fig. 5, in the platen 15 so that they may be adjusted to suit differing arrangements of bottles. Each is secured in its slot 30 by a nut 14, Fig. 1, which draws the guide 8 up so that a shoulder 11 on it enages a washer 10 which bears against a flange 9 on the housing 6 which engages the lower side of the platen 15. The extension of the tubular slide 7 under the action of the spring 20 is limited by a flange 22 on the guide 8. Bearing sleeves 23, 24 are provided on the housing 6 and slide 7. The gripping fingers comprise blade springs 16 secured to the slide 7 and carrying jaws 18. The lower end of the plunger 25 carries a part-conical member 28 for engaging the bottles while the upper end carries a button 26 by which it engages the releasing abutment when the platen 15 is raised. The abutment 29, Fig. 5, preferably comprises a heavy member mounted to slide on fixed pins 31 to accommodate differences in the adjustment of the gripping members. A light spring 27, Fig. 1, normally holds the plunger 25 in its raised position.

[Also in Division C7] A centrifugal casting process for composite bodies particularly rollers for rolling mills includes, supplying a molten mass of metal to a metallic mould, rotating the mould about a horizontal axis to cause the molten metal to contact the mould surface and solidify, adding a flux to coat the inner surface of the cast metal uniformly, maintaining the flux coating at 800 C. to 1300 C., erecting the mould vertically and adding a second mass of molten metal. The flux is of such a viscosity that if the mould is stopped rotating, or when the mould is erected vertically, a uniform thickness coating is maintained. When casting rollers, the first metal was cast iron and the second metal a different heavy duty cast iron. The flux may be introduced as a mixture with the first metal (in which case centrifungal force will separate the mixture forming a slag coating), or as a separate mass while the first metal is cast, or after casting of the first metal by sprinkling it on the metal's furface. The flux contains 50% wt. to 90% wt. of a mixture of silica and borax and 10% wt. to 50% wt. soda ash, NaCl, NaF, limestone, CaCl 2  or CaF 2 .

To test the freshness of fish or other animal or vegetable material the impedances at two different frequencies of a part of the material are measured simultaneously or in rapid succession and their ratio is used as an induction of condition. As shown in Fig. 4 two oscillators 0, and 0 2  are connected in series with two electrodes, between which is placed the sample, and a resistor R 3 . The voltage across the resistor R3 is fed to an amplifier V3 and their to separate high and low frequency amplifiers V1 and V2. The output of amplifier V1 is kept constant by feedback through A to the input of amplifier V 3 , the output of amplifier V 2  is also affected by this feedback and thus produces an output proportional to the ratio of the impedances at the two frequencies. Alternatively instead of the feedback path being used the outputs of the two amplifiers may be compared in a cross-field meter if transistor circuit incorporating temperature stabilization and a bridge circuit is described (Figs. 7, 8, 9, 10 not shown). The electrodes may be formed by graphite coatings on the thumb and index finger of an insulating glove. A pair of separate circuits feeding alternately the coil of a cross field meter are described with reference to Fig. 2 (not shown).

Title: Improvements in or relating to the preparation of thiadiazole-sulphonyl-halides and their conversion to sulphonamides
Filed: 1956-06-15
Abstract: The invention comprises a process for making thiadiazole sulphohalides, by the action of a halogen on a 5-acyl mercaptothiadiazole in presence of water. 2-Acylamino-5-acylmercapto-thiadiazoles are preferred, especially those in which the acyl groups are aliphatic acyl groups.  The thiadiazole sulphohalides may be converted into thiadiazole sulphonamides, e.g. by reaction with ammonia-particularly aqueous ammonia, or an amine.  In examples, 2-acetylamino - 5 - acetyl - mercapto - 1:3:4 - thiadiazoline, obtainable by the action of acetic anhydride on 2-amino-5-mercapto-1:3:4-thiadiazole, is treated with chlorine in aqueous suspension, and the sulphochloride, isolated, is treated with aqueous ammonia, followed by glacial acetic acid, to give the 2-amino- and then the 2 - acetylamino - 1:3:4 - thiadiazole - 5 - sulphonamide; the 2-amino-5-sulphochloride may also be converted without isolation into the sulphonyl propylamide; 2-chloro-5-acetylmercaptothiadiazole is converted into 2-chloro-1:3:4 - thiadiazole sulphochloride.
