Title: Improvements in and relating to electric switch devices for counters or the like
IPC: G01S1/02
Filed: 1948-08-06
Abstract: 652,808. Pulse circuits. COSSOR RADAR, Ltd., and LEVIN, A. Aug. 6, 1948, No. 20880. [Class40(vi)] The Figure shows a frequency dividing or pulse counting circuit in which negative-going pulses from a generator 10 which may for example have a pulse repetition frequency of one pulse every ten seconds, are applied to a normally conducting valve 11. The anode potential of valve 11 thus rises and after a period determined by the time constant of resistor 13 and the selected capacitor of group 14 valve 12 is rendered conducting to let through to the output 18 the next pulse from whichever of the pulse generators 17<SP>1</SP>, 17<SP>11</SP> is connected to the suppressor grid of valve 12 via switch S2 which is ganged to switch S1. The pulse generators 171, 17<SP>11</SP> each generate pulses having a repetition frequency of, for example, one pulse every two seconds and are arranged to give an interlaced sequence of pulses, in this way a greater accuracy is obtained than with a single generator. The two generators 171, 17<SP>11</SP> are synchronized from the main generator 10 via the link 19 and are synchronized with each other via the link 20.

Title: Improvements in and relating to nut-tapping machines
IPC: B23G1/18
Filed: 1925-08-21
Abstract: 239,199. Sprick, H. Aug. 26, 1924, [Convention date]. Tapping.-In a nut-tapping machine, the speed of rotation of the tap is decreased, when the tap meets with undue resistance, by automatically decreasing the angle of lap of the driving belt. The belt 24, driven from a power shaft 23, passes round pulleys 9, 10 and a jockey-pulley 11 urged by a spring or a weight to tension the belt. The pulleys 9, 10 are rotated in opposite direction on stationary bushes, the tap being driven through a pin clutch by either pulley. When the tap is checked the increased pull on the belt lowers the jocheypulley 11, decreases the angle of lap, and allows the. belt to slip. The jockey-pulley is mounted on a pivoted frame which may be manually operated.

Title: A process for the manufacture of secondary higher alcohols
IPC: C07C29/06
Filed: 1938-07-19
Abstract: 510,637. Alcohols by hydrolysis. FIFE, J. G. (Naamlooze Vennootschap de Bataafsche Petroleum Maatschappij.). 'July 19, 1938, No. 21467. [Class 2 (iii)] Secondary higher alcohols containing at least six carbon atoms in the molecule are prepared by hydrolysis of the product obtained by treating with sulphuric acid liquid cracked paraffinous hydrocarbon material, at least the greater part of the free sulphuric acid being removed and water or dilute acid added before the hydrolysis so that after the hydrolysis an acid is obtained having a concentration of 10-40 per cent. The sulphuric acid may be removed by adding a small amount of water and separating the aqueous lower layer formed. The upper layer containing the alkyl sulphates, non- converted hydrocarbons, polymers and some acid is further diluted and separated into an upper layer containing the greater part of the di-alkyl sulphates and a lower layer containing the mono-alkyl sulphates which is hydrolyzed by heating. The sulphated mixture after the second dilution, preferably after removal of the upper polymer layer, may be subjected to an extraction with pentane, benzene or gasoline in the presence of a demulsifying agent such as ethanol and hydrolyzed to produce pure alcohols. After hydrolysis the acid is separated off as lower layer and the upper layer, after adding a previous polymer layer, is subjected to a renewed sulphation treatment with highly concentrated sulphuric acid and worked up. An example is given of the preparation of C6-C9 alcohols from a C6-C9 cracked distillate fraction obtained by fractionation of a vapour phase cracking product of a paraffinous hydrocarbon material. A mixture of methyl and ethyl ketones can be prepared from the alcohols by catalytic dehydrogenation, e.g.,by means of a brass catalyst at above 450‹C. Specifications 463,282 and 478,841 are referred to.

Ink-ribbon mechanism.-(1) In arrangements comprising a revolubly mounted spool-cup 2, Fig. 3, and a pivoted ribbon-tensioning arm 12, a single tension-spring 16 is employed for retaining the cup and arms in the normal position. The spring may be caused to impart a strong pull on the cup and a weak pull on the arm by being connected to the cup at a point 18 remote from the pivot 3, and to the arm at a point 17 near the pivot 15. The cup is manipulated by a knob 21, the movement being limited by a slot 20 and screw 19. The ribbon passes through the slotted end 14 of the arm. (2) A ribbon vibrator consists of a forked member 10, Fig. 5, having at each side a slotted ribbon-guide of the following formation. The inner wall of the slot is formed with a finger 24 which extends across the slot and is bent rearwardly at the ends to facilitate threading the ribbon, and the outer wall of the slot is formed with a forwardly projecting lip 25, The ribbon passes behind the inner wall and in front of the outer wall, the finger 24 and the lip 25 projecting over the edge of the ribbon.

Abstract: 1384817 Holography MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 10 May 1972 [12 May 1971] 21867/72 Heading G2J Audio signals are recorded holographically by using the audio signal to modulate the object beam from a coherent light source, different signals being recorded as discrete holograms on a moving tape by interposing a slit between the interfering beams and the tape. The audio signal I (t) is converted into an angular displacement of a galronmeter which moves a mirror 5 on which the object beam is incident. Alternatively the mirror (29), Fig. 6 (not shown), may be fixed and the audio signal operate a light modulator (30). In a further embodiment the object beam may be split to give two or more portions each with its respective modulated mirror arrangement. Preferably the coherent light source 1 is a laser and may be pulsed or operated with a shutter 9 to give an intermittent output. The holograms recorded on tape 8 may be relief phase holograms, and record the sound for cinefilm, video-playback systems or television. In a playback arrangement, Fig. 4, a laser beam passes a cylindrical lens to give a slit shape reconstructing beam. The image bearing beam reconstrucstructed from moving tape 8 is focused on to a wedge filter 15 giving a uniform intensity output. This is fed to a photo-electric device 18 which demodulates the signal to give an audio-output at 20.
