IPC: F16B21/18
Filed: 1954-08-17
Abstract: 752,758. Circlips. WALDES KOH-I-NOOR, Inc. Aug. 17, 1954, No. 23915/54. Class 89 (2). A circlip 13, Figs. 1 and 4, to be seated in a groove 12 in a shaft 11 to secure a part 10 to the shaft, comprises a ring-body 22, Fig. 4, gapped to permit of its assembly into the groove transversely of the shaft, and provided on its ends 18, 19 with locking-projections 26, 27 to engage the outer periphery of the shaft to lock the circlip in the groove. The projections are formed by displacing the ends from the plane of the body which may be bowed about its horizontal centre-line to such an extent that it must be flattened during assembly. The diameter of the groove-engaging part of the ring is smaller than the diameter of the bottom of the groove. In another arrangement the circlip 35, Fig. 7, is bowed about its vertical centre line, and the locking-projections 44 are formed by bending up tongues from the ends 39. The body may be cutaway to form spokes 15-17, and the projections are sufficiently small to pass through the groove during assembly and disassembly. Specification 660,746 is referred to.

Title: Improvement in radio frequency field responsive devices
IPC: G01S1/02
Filed: 1945-09-18
Abstract: 618,860. Discharge apparatus. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Sept. 18, 1945, No. 24157. Convention date, March 31, 1944. [Class 39 (i)] [Also in Group XL (c)] A visible response to a radio frequency field, such as the reflected radiation in a microwave radar system, is produced by a device comprising a partially evacuated envelope 3, containing a mosaic 1 consisting of a plurality of cavity resonators 5. The envelope has at least one transparent face and is made of glass or preferably mica or quartz, and each resonator has a discharge gap 7 which breaks down under the effect of incident radiation of the frequency to which the resonator is tuned, to produce a visible discharge. A gas with a low ionizing potential such as neon or neon' plus 1 per cent argon is included in the envelope and ionizing or bias potentials may be applied between the mosaic and an annular electrode 9 from a transformer 15 and a steady bias source 17. The resonators, which are of dumb-bell form are provided with a long blunt gap if high illumination is required or with a sharp gap if high sensitivity is required and may be formed by piercing a conducting plate or by the deposition of a conducting film on insulating support. Alternatively, Fig. 4 (not shown), the mosaic may be formed with the resonators bounded by wires or conductive elements. To increase the resolution of the device the number of resonators per unit of effective area of the mosaic may be increased by folding the surface into ridges, Fig. 5 (not shown), and to reduce the coupling between adjacent resonators which broadens the response of the device, the resonators in adjacent rows or columns may be staggered, Fig. 6 and 7 (not shown). The sensitivity of the device may be increased by a suitably disposed reflector and the light output may be increased by coating the mosaic, or the reflector, or the front of the envelope with a fluorescent material.

Title: Improvements in or relating to cash registers and similar accounting machines
IPC: G06C11/02
Filed: 1929-08-10
Abstract: 319,318. National Cash Register Co., (Assignees of Shipley, B. M.). Sept. 20, 1928, [Convention date]. Cash-drawer mechanism.-In a cash register or similar accounting machine having a plurality of cash drawers, corresponding keys in the single and multiple item groups of clerk's keys select the same drawer for release. In a multiple-item operation the drawer is selected but remains locked until a total is taken. The invention is shown as applied to a machine of the Shipley type described in Specifications 8119/15 and 227,861. The single and multiple item groups of clerk's keys are arranged, the former below the latter, in a single bank, and through the usual differential mechanism, shaft 99 and gearing 122, 123, 126, 127 serve angularly to position a vertical shaft 118 carrying release-arms 130 - - 135 for the cashdrawers. The arms are arranged in oppositely disposed pairs so that depression of a single-item key places one of the arms 131, 133, 135 in operative position beneath the pertinent drawer-latch 116, while depression of the corresponding multiple-item key sets the opposite arm 130, 132 or 134 beneath the same latch. The vertical or releasing movement of the shaft is derived from a cam on the main shaft through a pitman 151 and a pin 157 extending from a lever 145 freely rotatable on the shaft 99 and having two arms 143, 144 that engage within an annular groove 140 in the shafe 118. The connection between the pitman 151 and the pin 157 includes a lug 159 extending from a yoke 154 and abutting the end of an arm 158 of a bell crank 156 freely mounted in the pin 157. In a single-item operation, the arm 158 is maintained in operative position to permit the release of a drawer by the engagement of the other arm 166 of the bell crank with the raised part of a cam 167 fixed on the shaft 99. In a multiple-item operation, a reduced part 168 of the cam 167 allows the bell crank to rotate under the action of a spring 165 and the drawerreleasing mechanism is thereby disabled. In a total-taking operation, a second arm 169 disposed adjacent the cam 167 and having a raised part 170 is rocked by the total-taking mechanism to return the bell-crank to operative position and enable the release of a drawer.

Title: Improvements in dyeing nitrogenous fibres
IPC: D06P3/04
Filed: 1960-07-14
Abstract: In the dyeing or printing of nitrogenous fibres by the process of the parent Specification, wherein the fibres are treated with an aqueous bath or paste containing a 1 : 2-chromium or -cobalt complex compound of an azo dyestuff, the complex containing at least two acid solubilising groups, together with a cationic surfaceactive compound, improved results are obtained by also incorporating in the bath or paste an organic, non-ionisable, hydrophilic compound that is at most restrictedly soluble in water such as benzyl alcohols, b -phenoxyethyl alcohol, geraniol, cyclohexanol, n-butanol, amyl alcohol, n-hexanol, 2-ethyl-hexanol and n-octanol.  The bath or paste may also contain a non-ionic dispersant.  Dyeing is effected from an acid bath at a temperature not exceeding 80 DEG C.  The fastness of the dyeings is improved by adding an alkaline substance, such as ammonia, hexamethylene tetramine, sodium bicarbonate or triethanolamine, to the bath after the fibres have absorbed the desired amount of dyestuff.  One example describes slubbing printing on woollen tops, the paste containing besides the dyestuff and tragacanth thickening trimethyl cetyl ammonium bromide, urea, benzyl alcohol and acetic acid.

IPC: H05B6/76
Filed: 1962-06-27
Abstract: 1,022,103. Microwave heating. DECCA Ltd. Sept. 9, 1963 [June 27, 1962], No. 24761/62. Heading H5H. [Also in Division H1] A closure 12 for a microwave cavity, e.g. a microwave oven 10, comprises a choking groove 15 arranged in a peripheral upstanding portion 13, 14 of the closure, the upstanding portion being intersected by grooves 16 which prevent resonance of the leakage energy. Such resonance may occur when the distance around the periphery is equal to a whole number of wavelengths and, to prevent this, grooves 16 are spaced less than a wavelength (e.g. half a wavelength) apart. As shown on the right-hand side of the Figures, the peripheral part 14 beyond the choking groove contacts the side of the oven 10. In this case the grooves 16 need only extend as far as the choking groove. Where the part 14 does not contact the oven (left-hand side of the Figures), the construction is modified by extending the grooves 16 through the part 14. The parts 13, 14 are dimensioned to present a quarter-wave path length to the leakage energy.

Title: Buttonhole sewing machine
IPC: D05B73/12
Filed: 1929-08-15
Abstract: 330,460. Fairweather, W., (Singer Manufacturing Co.). Aug. 15, 1929. Buttonhole - sewing machines; thread cutters.- In a buttonhole cutting and stitching machine of the type described in Specification 322,951, the thread-cutting mechanism is below the work and the work is clamped entirely round the stitching aperture in the work-clamp. Fig 1 shows the parts in the initial position of rest with the work-clamp in position for cutting a buttonhole, where it is held lifted by the high part 90<1> of the cam groove 90. The work is inserted below the raised clampfeet 25 and the machine started. The feet 25 are automatically closed upon the work and the clamp moved rapidly forward to the stitching position. When the work-clamp arrives at the stitching position, the eccentric part 93 of the cam 90 engages the follower roller 89 and rocks the lever 88 in a direction to raise its forward end, thereby lowering the work-clamp flat upon the cross-slide plate 29. The circular sewing aperture 47 in the lower clamp-plates 24 are thus lowered over the needle-throat member 11 which engages the under-surface of the work during the sewing. The stitch-forming mechanism is then started and the work-clamp given its usual step-by-step feeding movements to place the stitches round the buttonhole. When the sewing operation is completed and the stitch-forming mechanism comes to rest, the rapid-feed mechanism returns the work-clamp to its initial position for the cutting of the button-hole and the sewing threads. Before the work-clamp is shifted away from the sewing position, a second eccentric portion 94 of the cam 90 rocks the lever 88 to elevate the work clamp to raise the lower clamp-plates clear of the needle-throat member 11, in which raised position the work-clamp is shifted to button-hole cutting position, Fig. 5, and the sewing threads are drawn out from the needle-throat member, these threads t extending at an upward inclination from the needle-throat to the last stitch and being separated from the under surface of the work to provide a space for entry of the upper pointed blade 52 of the cutter as described in Specification 322,951. The button-hole cutter levers 15, 16 are advanced and closed upon the work as shown in Fig. 5, and immediately opened, retracted, and brought to rest, by the cams 20, 21.
