Title: Improvements in or relating to periscopes
IPC: G02B23/08
Filed: 1920-07-10
Abstract: 148,452. Optische Anstalt C. P. Goerz Akt.-Ges. March 28, 1919, [Convention date]. Periscopes.-In order that the observer may control the extension or rotation of the periscope without undue disturbance, the handles controlling the movements are arranged so that they are in a fixed position relative to the eye-piece. A handle 3 is mounted a short distance above the eye-piece 2 of the periscope 1, and is used to operate the switch 16 controlling the motor which rotates the periscope 1. The handle 3 has mounted on it the wheel 4 acting as a planet wheel in conjunction with wheels 5, 6 mounted on the spindle 7. The wheel 5 is secured to the spindle 7 together with the wheel 9. Movement of the handle 3 in a horizontal plane rotates the spindle 7, since the wheel 6 is fixed by the wheel 10, being in engagement with the wheel 18 on the casing 19, causing wheel 9 to turn the plate 12 operating the switch 10 by the shaft 15. The motor is thus started and continues to turn the periscope until the handle 3 is restored to its normal position. The toothed rims 11, 18 operate the wheels 9, 10 and rotate wheels 5, 6 in opposite directions at the same speed so that the wheel 4 merely rotates on its axis. In a modification, the handle 3 is arranged to control both the rotation and the extension of the periscope by means of a vertical as well as horizontal movement. The additional movement operates similar gear to that mentioned above, which controls a separate motor for extending the periscope. In a further mcdification, the handle 3 may be duplicated for separate control of rotation and extension.

Filed: 1949-08-08
Abstract: A quaternary ammonium salt of formula <FORM:0673859/IV (b)/1> where -N=B is an aliphatic type tertiary amino group, R is alkyl or aralkyl of 1-8 carbon atoms, and X is the anion of a non-toxic strong acid, is prepared either by mixing the free amine with the compound RX, or by treating the quaternary hydroxide <FORM:0673859/IV (b)/2> with the acid HX.  The group -N=B may be dialkylamino, e.g. dibutyl- or butylpropyamino, or <FORM:0673859/IV (b)/3> where Y represents the atoms necessary to complete a 5- or 6-membered ring, e.g. -CH2-, -CH2.CH2-, -CH2.O-, or -S-.  RX is the ester of an inorganic acid or aromatic sulphonic acid, e.g. methyl chloride or bromide, benzyl bromide, methyl or ethyl sulphate, and methyl benzene- or p-toluene-sulphonate.  The reaction takes place with or without a solvent and with or without heating.  The initial amines are prepared by alkylation of diphenylacetonitrile with a b -tert.-aminoethyl halide.  The quaternary ammonium hydroxides are prepared by treatment of the salts with, for example, silver hydroxide.  In the examples, (1) diphenylacetonitrile is condensed with diethylaminoethyl chloride to give 2 : 2-diphenyl-4-diethylaminobutanenitrile, and the formation of its methochloride and methiodide by treatment with methyl chloride and methyl iodide respectively.  Other examples included describe the preparation of 2 : 2-diphenyl-4-(N-piperidyl)-butanenitrile its methiodide and its benzochloride, 2 : 2 - diphenyl - 4 - (N - pyrrolidyl)-butanenitrile and its methiodide.

Title: Fluid control valve
IPC: F15B13/08
Filed: 1964-05-19
Abstract: 1,000,125. Valves. COMMERCIAL SHEARING & STAMPING CO. May 19, 1964 [Oct. 11, 1963], No. 20681/64. Heading F2V. A valve bank consists of an inlet section 10, two or more parallel circuit valves 11, 12 and a regenerative section 13 housing a valve 26; upon delivering pressure fluid to an inlet port 14 the fluid divides and flows along the centre and parallel passages 17, 18 of the valves 11, 12. The fluid in passage 17 passes to a tank 35 via channels 36, 34 when the valves 11, 12 are in the central position; when one of these valves is in an operating position the passage 17 is blocked but fluid continues to flow through passage 18 to a chamber 31 and moves the valve 26 against an adjustable spring 27 to interconnect two further chambers 28, 29. This enables fluid discharged from the ram or other apparatus controlled by valves 11, 12 to exhaust via passages 21, 20 of valves 11, 12 through chambers 28, 29 to the tank 35; if the ram is lowered so rapidly that the pressure in passage 18 falls, then the valve 26 is returned to the position shown by the spring 29 so forcing the fluid in passages 20, 21 into passage 18 to supplement the input fluid and prevent cavitation in the ram. A relief valve 32 is provided in valve 26.

Title: Tuning indicator for radio receivers and the like
IPC: H03J1/04
Filed: 1936-07-27
Abstract: 470,597. Adjusting wireless apparatus. PHILCO RADIO & TELEVISION CORPORATION. July 27.1936, No. 20755. Convention date, April 27. [Class 37] A tuning indicator for wireless receivers or the like comprises a movable translucent dial having indicia thereon and a translucent slotted screen situated between the dial and a lightsource, focusing means being associated with the slot in the screen for producing a sharply defined light-image upon the dial. The shaft 7 for varying the tuning condensers 3 of the receiving set is geared to a rotary support 13 to which is attached the translucent dial 14. Light from a lamp 19 is directed through a slot 26 in a translucent screen 25 and is brought to a focus as a line of light on the dial 14 by a glass rod 21, situated at a distance from the dial equal to slightly less than one half the radius of the rod. The width of the slot 26 is approximately equal to the radius of the rod 21. Owing to the translucent nature of the screen 25, the background is generally illuminated and no shadows are cast thereon. The area illuminated is, however, restricted by a further translucent disc 27 provided with arcuate openings staggered radially and each arranged to co-operate with a set of indicia carried by the dial 14, the sets being arranged on the dial in concentric circles, one circle for each wave band. By this means, the aperture in the screen 27 positioned behind the slot 26 in the screen 25 defines a background area for the bright image focused by the glass rod 21 which' is more brightly illuminated than the remaining background area which is defined by the window in the supporting frame 20, and the aperture also restricts the length of the bright image to the indicia relative to the wave band in use. The screen 27 may be rotated to bring a different aperture into operative relation with the dial by operating the wave-change switch 34, the shaft 32 of which is connected to the support for the screen by a crank arm 31 and link 30. The rotary dial 14 is guided by front projections 35 and rear supports 37, carried by the frame 20.
