Title: Improvements in or relating to methods and apparatus for turning rod stock to produce
IPC: B23Q1/00
Filed: 1957-10-28
Abstract: 860,412. Turning projectiles. LAUTERBACH, W. Oct. 28, 1957 [Oct. 26, 1956], No. 33634/57. Class 83 (3). In a method of turning articles such as projectiles from bar-stock, a tool first operates to form a tail-portion of a first article and then forms a region of reduced cross-sectional area joining the tail-portion to the remaining length of bar-stock, thirdly the head-portion of a second article is formed by the tool, after which the first article is severed from the stock. Barstock 30, Fig. 2, is held in the chuck 1 of an automatic lathe and one article 40, supported by a tailstock, has already had the head-portion turned. A tool 2b starts from a point S and turns the tail-portion 40b of a projectile case along path IIa. The tool then turns a part IIb of reduced diameter, and then proceeds to a rough-shaping of the nose of a second article along path IIc. While the last operation is continuing, a further tool 7 moves in to part-off. The tool 2b meanwhile returns along the path IId, and when the parting-off is completed, reverses along path IIe to finish the nose portion of projectile 40a. Feed-motion for generating.-A control-shaft 19, Fig. 3, driven by means (not shown), in timed relation to other parts of the lathe, is provided with a face-cam 13 and an edge-cam 16. The former operates a double-ended lever 12 to reciprocate a spring-returned bar 11 secured to a rockable tool-bar 9 carrying a tool 10. A roller 17 on the other end of the tool-bar is spring-pressed into engagement with the edge-cam 16 for the transverse movements of the tool.

Patent GB-398192-A (GB)
Title: Improvements in the manufacture of cellulose derivatives and products obtained therefrom
IPC: C08B3/06
Filed: 1931-12-04
Abstract: Cellulose acetates giving non - delustring products, particularly artificial silk, are obtained by limiting the ripening process in such a manner that although acetone solubility is reached, yet the process is not allowed to proceed so far as normal acetone solubility, that is to say, the acetyl content is reduced to only 56-60 per cent calculated as acetic acid, preferably to 56-57 per cent.  The acetates treated are obtained with the aid, as catalysts, of sulphuric acid, phosphoric acid or other oxy acids or derivatives of such acids, and the ripening is carried out under conditions such that any acid present is an oxy acid.  The ripening is carried out with the customary proportions of water or other ripening agent, or with reduced quantities of water, that is, 5-15 per cent calculated on the weight of the original cellulose, or with partial neutralization of the acid catalyst before or during ripening, or by a two-stage process in which there is first added water or other ripening agent in quantity sufficient to destroy any excess of acetylating agent or equivalent to \ba1/2\be-1\ba1/2\be such amount, and then adding at a later stage a further quantity of water &c.  The acetylation process is carried out at a temperature below 40 DEG  C. in order to avoid degradation of the cellulose, and it may be conducted in solution or in suspension, in which case the ripening is also carried out in suspension.  Specifications 20977/11, 20852/12, 6463/15, 14101/15, 100,009, 207,562, 263,938, [all in Class 2 (ii), Cellulose &c.], and 350,417 are referred to.  The Specification as open to inspection under Sect. 91 refers to the application of the process to cellulose esters other than acetates.  This subject-matter does not appear in the Specification as accepted.

Title: Spinneret for the production of a plurality of hollow filaments
IPC: D01F1/08
Filed: 1959-10-06
Abstract: A spinneret for the production of a number of hollow filaments comprises three superimposed plates of which the plate 1 (Fig. 1) constituting the base of the spinneret is provided with a number of spinning orifices 6 and with alignment bores 7 for dowels 17. The middle plate 2 has a central opening 8 which is enlarged downward to form a supply chamber 9 of relatively large diameter for the spinning solution or spinning melt.  An annular recess 10 is provided in the lower surface of the upper plate 3 from which a gaseous or liquid medium for introduction into the filament axis is distributed to the spinneret orifices.  The medium is supplied to the recess 10 by a number of ducts 18 and a number of tapered bores 11 extend from the recess 10 to the chamber 9.  Axially drilled tapered pins 12 (Figs 1 and 3) terminating in capillaries 13 are secured in the bores 11 by means of axially drilled screws 14 which are screwed into the threaded upper portions of the bores 11 and bear down upon the pins 12, which are thereby forced into the bores 11 to form gas and liquid tight push fits therein.  The gaseous or liquid medium from the recess 10 passes through the central bores 15 in the pins 12 and then through the capillaries 13 into the filaments as they are being extruded from the orifices 13.  A thin aluminium gasket 21 is provided between plates 1 and 2 and 2 and 3 to form gas and liquid tight seals between the plates. At least three dowels 17 are firmly fixed in the plate 2 and are an accurate sliding fit in the bores 7 in the plate 1.  The upper plate 3 has a central opening 16 through which spinning solution or melt is fed via opening 8 to the supply chamber 9.  The lower part of the portion of the pin 12 which projects into the plate 1 is provided with vertical grooves 19 (Figs. 2 and 3) through which the spinning solution or melt is forced to the spinning orifices 6.  Vertical ribs 20 between adjacent grooves ensure exact centring of the pin in its bore.  The three plates are held together by screws of which four are shown at 21 to 24.  In the spinneret of the parent Specification each axially drilled pin 12 instead of being tapered is cylindrical and is provided with a shoulder which is pulled up tightly against the underside of the plate 2 when the screw 14 is screwed into the threaded upper portion of the central bore of the pin, the underside of the head of the screw bearing on the upper surface of the plate 2.  The bores 11 in this case are cylindrical and not tapered and the pins are a close sliding fit in the bores. <PICT:0929430/IV(a)/1> <PICT:0929430/IV(a)/2> <PICT:0929430/IV(a)/3>

Title: Channel selecting apparatus
IPC: C03B37/08
Filed: 1976-08-16
Abstract: 1518368 Tuning arrangements for TV receivers SONY CORP 16 Aug 1976 [27 Aug 1975] 34013/76 Heading H3Q In a channel selecting apparatus for a television receiver having a tuner 100 with a voltagecontrolled variable reactance tuning element, read out of a selected one of digital codes identifying respective channels from the respective address of a memory 50 by selection at S1-S16 is converted by a D/A converter 90 including a pulse width modulator 91 to an analogue voltage for controlling the variable reactance element. To programme the memory 50 a mode change switch 61 is switched to position a and operation of address selection switch S1 selects by, address counter 71, one of sixteen memory units (51 1 -51 16 , Fig. 2, not shown) of the memory 50. A counter 40 is reset by circuit 77, 45, 44 and 48. A sweep generator 30 alters the count in the counter 40 under control of coarse up and down switches 31 CU, 31 CD or fine up and down switches 31 FU, 31 FD until the required television channel picture is tuned. Pulses for fine up and down counting of the counter 40 are obtained from a timing counter 20 via a frequency divider 35. The digital output B1 to B14 of the counter is then read into the memory 50 together with a digital representation of the selected band from band memory 84, as selected by switches SL, SH, SU for lower VHF, higher VHF and UHF bands on operation of a write switch 62. The D/A converter 90 includes a pulse-width modulator (Fig. 3 not shown) which includes exclusive OR circuits (901-914) OR circuit (93) and a flip-flop (94) and produces a chain of pulses with the width of each of the pulses being dependent on the absence of coincidence between the channel identifying code B1-B14 (Fig. 4C, not shown) and a circulating digital code A1-A14 (Fig. 4B, not shown) from the timing counter 20. The output pulses P w  (Fig. 4E, not shown) of width depending on these codes is fed via a LPF 92 to a variable capacitance diode of the electronic tuner 100. Selection of a stored channel is obtained by switching mode change switch 61 to position b and operating a required switch S1-S16. The digital code corresponding to the addressed memory unit of memory 50 is then read into the counter 40 and the corresponding output from the D/A converter 90 tunes the electronic tuner 100 to the selected channel. Neons N1-N16 indicate the channel selected. When the power supply is turned on address counter 71 resets to address the first memory unit (51) in memory 50. The memory units are of non-volatile cells, such as MNOS elements which hold their contents unchanged when memory 50 is disconnected from a power supply. In a modification (Fig. 5, not shown) fine up or down tuning pulses from a divider (138) are applied for a time of 5 seconds as determined by a monostable (136) when the up or down switch of the sweep generator 30 is first closed and then coarse tuning pulses occur until the switch is opened. The channel selecting apparatus may be formed as an integrated circuit.
