Title: Improved process of sensitising silver halide emulsion layers
IPC: G03C1/18
Filed: 1933-06-07
Abstract: Silver halide emulsions are sensitized by the use of aminosubstituted benzthiocarbocyanine dyes having an alkyl group attached to the middle carbon atom of the trimethine chain.  The amino groups may be unsubstituted or may be substituted by, for example, methyl, ethyl, propyl, or acetyl groups.  Examples are given of the preparation of (1) 1 : 1<1>-diethyl-6 : 6<1> - bisdiethylaminobenzthio - b  - methyl carbocyanine iodide by heating 2-methyl-5-diethylaminobenzthiazole ethyl iodide with ethyl orthoacetate in dry pyridine; (2) 1 : 1<1>-diethyl - 6 : 6<1> - bis - diethylaminobenzthio - b  - ethyl-carbocyanine perchlorate by heating the base of (1) with ethyl orthopropionate in dry pyridine; and (3) 1 : 1<1>-diethyl-5 : 5<1>-bisdiethylamino-b -methyl-carbocyanine perchlorate by heating 6-diethylamino-2-methylbenzthiazole with ethyl orthoacetate in dry pyridine.  In examples 2 and 3 the dye is precipitated by the addition to the solution in pyridine of sodium perchlorate.  The base 2-methyl-5-diethylaminobenzthiazole ethyliodide is prepared from para-bromodiethylaniline analogously to the production of 2-methyl-5-dimethylaminobenzthiazole described in example 2 of the parent Specification and the base 6-diethylamino-2-methylbenzthiazole is prepared as described in example 1 of the parent Specification. The Specification as open to inspection under Sect. 91 describes also the preparation and use of benzselenazole dyes.  In examples: (1) 1 : 1<1>-diethyl-5 : 5<1>-bis-acetylaminobenzseleno-b -methyl-carbocyanine bromide is prepared by heating 6-acetylamino-2-methyl-benzselenazole ethyl sulphate with ethyl orthoacetate in pyridine; and (2) 1 : 1<1>-dimethyl-5 : 5<1>-bispropionylaminobenzselenazole - b  - ethyl - carbo - cyanine bromide is prepared by heating 6 - propionylamino - 2 - methyl - benzselenazole dimethyl sulphate with ethyl orthopropionate in dry pyridine, the dyes being precipitated with potassium bromide in both cases.  The selenazole bases are prepared by the action of acetic or propionic anhydride on 2-methyl-6-aminobenzselenazole prepared by nitrating 2-methyl benzselenazole and reducing the nitro group with stannous chloride and hydrochloric acid or iron powder and acetic acid.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements relating to slicing machines
IPC: B26D1/143
Filed: 1927-06-21
Abstract: 296,502. Maatschappij tot Vervaardiging van Snijmachines Volgens van Berkel's Patent en van Andere Werktuigen, and Berkel, C. F. M. van. June 21, 1927. Cutting slices in succession.-A disc knife reciprocating table machine is driven by hand or by power, the transmission mechanism being such that the entire machine can be operated by either the hand or the power mechanism, or part of the machine can be operated by the hand and/or part by the power mechanism, the part of the machine driven by hand being disconnected from the power-driving mechanism. As shown in Fig. 1, a motor 4 drives a pulley 8 by a belt 7. The pulley 8 has a free wheel connection, e.g. of the wedging ball type, with the knife shaft 9 which is connected by a sprocket chain 19 with bevel gearing connected with the handwheel shaft 10. A clutch, e.g. a spring-loaded cone clutch, couples the sprocket 18 with the shaft 16, and is disconnected when desired, by a rod 29 and a bell crank lever. When the entire machine is driven by hand, the sprocket 18 is clutched to the shaft 16, and, in virtue of the free wheel, the motor is not rotated. When the sprocket 18 is de-clutched, the knife may be rotated by power and the carriage remains stationary or is reciprocated by the hand gear. The carriage may be reciprocated by hand whilst the knife remains stationary. In a modification, Fig. 4, a counter-shaft 42 carries fast and loose pulleys 41, 44, and a sprocket 40 is fast on the shaft whilst another sprocket 43 is secured to the loose pulley 44. The sprockets 40, 43 are connected by chains 47, 46 to the knife shaft 9 and the carriage driving shaft 16. The carriage and the flywheel are connected to the shaft 16 in the same manner as in the previous construction. The motor shaft drives the belt pulley 6 through a free-wheel and the belt 7 is shifted by a member 48 which is held by a detent in one of three positions and may carry a motor switch at its end. When the entire machine is driven by hand, the belt 7 is in the middle position and wraps both the fast and loose pulleys 41, 44, whilst the motor shaft, in virtue of the free wheel, does not rotate. When the belt wraps either the fast or the loose pulley, and the handwheel is turned, the carriage is reciprocated but the knife remains at rest. When the motor is used, and the belt 7 wraps both pulleys, the whole machine is operated. When the belt wraps the fast pulley 41 only, the knife only is driven by power. When the loose pulley is wrapped, the carriage only is driven by power.

Abstract: 870,061. Heating yarns by electric resistances. PYE Ltd. May 22, 1959 [May 28, 1958], No. 17004/58. Class 39(3). [Also in Group IX] In the heat treatment of a filamentary material passing along a focal axis of an elliptical reflecting chamber in which an electrical heating element is disposed along the other focal axis, means are provided for effecting relative displacement between the material and the focal axis along which it is normally located, or for deflecting the heat rays from this axis, should for example, the speed of movement of the material decrease or a previous-, processine step cease to function normally As shown in Fig. 1, heat rays from the heating element 3 are reflected and focused on to a moving nylon yarn 6 by two semielliptical reflectors 1 and 2. Reflector 2 is supported by a rod 8 pivoted at its ends 9 and normally held stationary by means of a spring 10 and, the armature 12 of an electromagnetic relay acting in opposition. If the speed of the yarn decreases or if the processing effected by rotating wheels 15a, 15b is not functioning properly, switches S1, S2 are opened, relay 11 is de-energized and reflector 2 automatically turns about the rod 8. The relay circuit may also be opened if the tension of the yarn falls outside certain limits. The tensioning device includes guide pulley 16, spring 17, and contacts C1. Overheating of the heater 3 is prevented by the device 5 in which contact C2 in the supply circuit is temporarily opened on expansion of the heater. In modifications, reflectors 1, 2 are replaced by a single completely elliptical reflector, or, Fig. 3, a baffle 19 turns into position 19a to interrupt the heat rays, or, Fig. 4, the yarn 6 passes several times through the reflector assembly 1, 2 for preheating before passing along the focal axis. The heating element may be a straight wire or a coil within or about a tubular ceramic support.
