Title: Process for the production of fast black dyeings on textile materials or foils of high-melting linear polyesters
IPC: D06P1/32
Filed: 1958-01-15
Abstract: Oxidation dyeings are produced on linear polyester textiles or foils by applying a polynuclear black base and then oxidizing with an acidified hypohalite solution, or a preferably acidified solution or dispersion of a compound yielding a hypohalous acid on hydrolysis, or an acidified solution of a chlorite.  Specified polynuclear bases are 4-amino-diphenylamine, 4-methyl-41-amino-diphenylamine, 2 : 41-diamino-diphenylamine, 2-methoxy-4-amino-diphenylamine and 3-methoxy-4-amino-diphenylamine.  The bases may be employed in admixture with one another or with other bases such as benzidine, p-tolidine, p-dianisidine, 1 : 8- (or 1 : 5-) diamino-naphthalene, o-, m- or p-phenylene diamine, m- or p-aminophenol or a -naphthylamine.  Specified compounds yielding a hypohalous acid on hydrolysis are N-chloro- (or N-bromo-) carbamic acid ethyl ester, esters of hypohalous acids, and N-halogen-compounds of cyclic imides or of sulphonamides, such as N-bromo-succinimide, benzene sulphonic acid dichloramide, p-chlorobenzene sulphonic acid dichloramide, the sodium salt of p-toluene sulphochloramide or N : N1-tetrachloro-1 : 3-dimethyl-benzene-4 : 6-disulphonic acid amide.  The base may be applied in aqueous solution or dispersion at 85 DEG -100 DEG C., or at above 100 DEG C. under pressure, in the presence of carriers, such as diphenylene oxide, o-phenyl-phenol, diphenyl ether, tetrahydronaphthalene or chlorobenzene, and dispersing agents, such as alkyl sulphates, alkyl-benzene sulphonates, alkyl-sulphimides, sulphocarbo-imides, oxyethylates, alkyl-phenols and sulphuric esters thereof and cationic dispersing agents, many of which are specified. Oxidation may be initiated by applying a hypochlorite solution at a low temperature and then completed by applying a compound, such as an aromatic sulphoamide, capable of being halogenated at the N atom, with increasing temperature.  The base may be applied to unstretched or only slightly stretched polyester fibres.  Numerous examples are given.

Title: Improvements in or relating to ultrasonic vibratory apparatus
IPC: G10K11/00
Filed: 1966-01-13
Abstract: 1,130,441. Ultrasonic wave couplings. UNION SPECIAL MACHINE CO. 13 Jan., 1966 [13 Jan., 1965], No. 1565/66. Heading H4J. [Also in Division B5] Vibratory apparatus for ultrasonic welding of thermoplastic sheet material includes a vibratory, exponential, tool 10 and an opposed jaw 11. Protrusions are formed in the facing surfaces 12, 13. The tool 10 is vibrated by a piezoelectric transducer (42), Figs. 2, 3 (not shown) energized by an ultrasonic source of fixed frequency. The tool 10 is supported at a node by three screws 17 (see also Fig. 4, not shown) which bite into the side of the tool 10 and are carried in a support-plate 16. Electrical connection from the ultrasonic source to the transducer 42 is via two jacks 34, 35. Jack 34 is connected to a brass disc (32) resting within a rubber cup 30. Between the disc (32) and the transducer 42 is a slightly compressed cylinder of resilient wire mesh (40). The transducer 42 has silver electrodes (43). The upper surface of the transducer 42 and the lower face of the tool 10 are bonded together by epoxy resin (45) in which are silver particles (46). Jack 35 is electrically connected by cable (37) to the support plate 16 and through the screws 17 and conductive epoxy resin (45) to the transducer 42. The transducer may be magnetostrictive (not shown). A blower unit 76 controls the temperature of the vibratory tool 10. Coarse adjustment of the weld gap is effected by unlocking lock member 61 and sliding an arm 60 on a standard 58. Fine adjustment is effected by loosening wing screws 64 and rotating a knurled knob 63 to move a rack 62 in a vertical direction. The rack 62 supports a C-shaped head 68, apertures 71, 72 of which accommodate a rod 73 which carries the jaw 11. A strong spring 75 permits limited upward movement of the jaw 11 if the amplitude of vibration of the tool 10 is too great or if the weld gap has been set inaccurately. An alternative vibratory tool (85), Fig. 5 (not shown), has two oppositely disposed inwardly tapering flat surfaces (86, 87) adjacent the lower end. The upper portion (88) forms an extension and is of rectangular crosssection. The current path from the lower support plate (90) to the transducer (42) is by an epoxy layer (91) in which are distributed silver granules (92), instead of by the resilient wire mesh (40).

Title: Improvements in means for handling flat articles
Inventor: PACKMAN PERCIVAL JAMES
IPC: A21C15/00
Filed: 1958-01-17
Abstract: 863,941. Packaging. FORGROVE MACHINERY CO. Ltd. April 6, 1959 [Jan. 17, 1958], No. 1658/58. Class 94(1). [Also in Group XXX] In apparatus for removing batches of biscuits 20, or like flat articles, from the head of an advancing column in which they are stacked on edge and transferring them to weighing or packaging apparatus, stops 26, Fig. 1B, are provided for arresting the head of the column and the transfer is effected by gripping jaws 40 which are reciprocated along a guide 60 and are designed to engage a measured length of biscuits at the head of the column. The biscuits are fed by the apparatus described in Specification 876,878 on to a fixed track, Fig. 6, comprising side supports 25 and a bottom support 24. The grippers 40 are rubber pads 45, Fig. 8, which are supported by bell-crank levers 46 pivoted to a carriage 47. A spring 48 maintains the jaws in gripping position, but they are opened when pressure air is admitted to the cylinder 50 to project its rod 51 against the horizontal arms of the levers. As the pads move towards the biscuits, they press a pair of spring metering fingers 113 against the biscuits immediately behind the batch to be transferred and prevent their removal. The carriage 47 is reciprocated by a link 53 driven by the main drive shaft of the machine. Another pair of grippers 44 arranged upstream of the fingers 113 closes on the biscuits before the grippers 40 reach the pick-up position and then moves upstream to retract the biscuits to the rear of them and thus relieve the pressure on the stops 26. When the grippers 40 reach the pick-up position, a striker 109, Fig. 4, on the carriage closes a switch 110 which establishes a circuit to cause withdrawal of the stops 26. As soon as the grippers 40 close on the biscuits, the grippers release them and return to their forward position. As soon as this position is reached, the conveyer feeding the biscuits on to the tracks 24, 25 is restarted and the biscuits are fed towards the stops. Air jets 114 prevent toppling forwards of the biscuits during this movement. As soon as the carriage 47 moves to the right, the stops are returned to operative position. At the conclusion of the movement to the right, compressed air is admitted to the cylinder 61, thereby causing the grippers to open and deposit the biscuits on a scale pan 65. After weighing the batches of biscuits are transferred by grippers 42 to the pockets of a conveyer 43 which feeds them to a wrapping machine. Specification 801,564 also is referred to.
