Title: Window for x-ray microanalyzers
IPC: H01J37/252
Filed: 1964-08-14
Abstract: 1,027,909. X-Ray tubes. COMPAGNIE D'APPLICATIONS MECANIQUES A L'ELECTRONIQUE AU CINEMA ET A L'ATOMISTIQUE "CAMECA." Aug. 14, 1964 [Aug. 27, 1963], No. 33387/64. Heading H1D. An X - ray microanalyzer comprises an enclosure 1 for the electron optics system and the sample and a second enclosure 4 for the X-ray sensitive systems, with the partition wall between the enclosures having at least one opening 21 (22) and two movable windows 12, 13 (11) for being selectively brought into register with opening 21 (22), window 13 being permeable to soft X-rays and window 12 (11) being permeable to hard X- rays and also being capable of withstanding great pressure differences on its faces. In Fig. 1 (not shown), high vacuum enclosure 1 contains a cathode 21 and an electron optics system including control electrode 22, accelerator anode 23 and electromagnetic focusing lenses 24, 25 which direct an electron beam on to a sample 3 to be analyzed. The X-rays pass into enclosure 4 through an opening which can be closed by window 7 to monochromator crystal 5 and a radiation counter 6. Enclosure 4 may have a lower vacuum than enclosure 1. By way of example, enclosure 4 is assumed in Figs. 2 and 3 (not shown) as having two spectrometers, one for hard rays X 1 , X 1 <SP>1</SP>, the other for soft rays X 2 , X 2 <SP>1</SP>. Windows 11, 12, 13 are mounted in a support 7 slidably mounted at 8 and can take up two different positions, Fig. 2 and Fig. 3 (not shown). Windows 11, 12 are of beryllium and can withstand a pressure difference of one atmosphere. Window 13 is a fragile collodion window capable of withstanding only a low pressure difference. The position in Fig. 2 is used when the vacuum in enclosure 4 is lower than in enclosure 1 or when analyzing hard X- rays in which case fragile window 13 is unnecessary. The position in Fig. 3 (not shown), is when window 13 is opposite opening 21 and is used when analyzing soft X-rays in which case there is a high vacuum in enclosure 4 substantially the same as in enclosure 1.

Title: Electronic musical instrument
IPC: G10H7/00
Filed: 1976-08-12
Abstract: 1533132 Electronic musical instruments NIPPON GAKKI SEIZO KK 12 Aug 1976 [21 Aug 1975] 33515/76 Heading G5J An electronic instrument of the kind having a memory storing numerically an attack-decay envelope is organized so that during a single depression of a key the memory can be read repeatedly and the amplitude of the musical tone repeatedly varied to provide a "repeatattack" effect. In Fig. 4 a counter 71, which operates in time-shared manner in twelve channels corresponding to twelve notes which may be played simultaneously, is incremented by clock pulses on line 74; at each count the value in the counter addresses the memory which delivers a value representing the instantaneous amplitude of the tone; every 64 counts a complete envelope is read out. A gate 99 is arranged to inhibit the pulses on line 74 when the counter is full, so the tome is sounded only once, unless a switch 91, 92, 93 is closed when the counter recycles continuously until the key is released. Different switches 91, 92, 93 introduce the repeat effect on different keyboards. When the key is released the counter continues to count to full from a fast clock causing a rapid decay (Fig. 6(d), not shown).

Title: Improvements in picture telegraphy apparatus
IPC: H04N1/036
Filed: 1946-11-12
Abstract: 669,812. Copying-telegraphy; light modulating. DONALDSON, S. Feb. 22, 1950 [Nov. 12, 1946], No. 33599/46. Class 40 (iii). In a picture telegraphy receiving apparatus, an electric lamp. 1 projects a light beam by way of prism 2 and condenser lens 3 on to an oscillograph mirror 23 and thence by way of an adjustable projection lens 5 on to a sensitive recording surface carried by drum 7. A mask having a rectangular aperture formed on one face of the prism restricts the beam to a rectangular cross-section and a triangular aperture formed in a mask 4 causes variation in the intensity of the light reaching the recording surface as the received signals cause the oscillograph to deflect the beam with respect to the aperture. Lens 3 focuses an image of the lamp filament on the oscillograph mirror and lens 5 focuses an image of the mirror on the recording surface. Mask 4 is located at the conjugate focus of the rectangular aperture produced by lens 3. The longer side of the rectangular aperture is made parallel to the longer axis of the oscillograph mirror which is also parallel to the base of the triangular aperture. A rectangular mask is mounted in front of the oscillograph mirror to obscure the support ribbons. Lens 5 is a fixed focus lens and is mounted for focusing adjustment by rod 9 moving in a slanting slot. The assembly of oscillograph, condenser lens and lamp is carried by mounting 14 slidable in relation to mounting 15 carrying the projection lens. If a variable focus lens is employed, the whole of the lens is arranged to be adjustable with respect to drum 7. The assembly is mounted on a carriage 16 and is moved by rotation of spindle 17 parallel to the axis of rotation of drum 7. An observation mirror 12 viewed through tube 13 is used in aligning the apparatus, the mirror being withdrawn from the path of the light beam before the apparatus is put into use.

Title: Automatic choke device for internal combustion engines
IPC: F02M1/10
Filed: 1974-07-30
Abstract: 1471744 Automatic chokes ALFA ROMEO SpA 30 July 1974 [30 July 1973] 33657/74 Headings F1B and F1H An automatic choke consists of a butterfly type choke valve 3 mounted wholly upstream of the carburetter 2 and which causes enrichment of the mixture by reducing the density of the air flowing through the carburetter, the angular position of the choke valve being automatically regulated in response to engine temperature and so that at any given engine temperature the pressure drop across the choke valve is constant regardless of variations in the amount of air drawn in by the engine. Choke valve 3 is mounted in duct 1 in which a  Venturi section 4 is formed and is connected by linkage 9, 10, 11, 12 to diaphragm 14, biased by compression spring 22 and subject on the underside to the pressure at Venturi 4 and on the upper side to the pressure in duct 1 upstream of the choke valve. The depression beneath diaphragm 14 is modified by admitting ambient air through filter 44 and pipe 20 at a rate controlled by valvemember 23, biased to the closed position by spring 26 and moved towards the open position when the engine is cold by a bi-metal spring 24 situated in an engine coolant duct 25. When the engine is hot, valve-member 23 is closed, and the depression at Venturi 4 moves choke valve 3 to the fully open position. At lower engine temperatures valve-member 23 is partly open and the effective depression is reduced so that choke valve 3 adopts a position dependent on engine temperature and on the rate of flow through Venturi 4. Fast idle device. Engine power output is controlled by throttle valve 6 through driver-operated linkage 28, 29, 30. The minimum open position is determined by stop screw 33, arm 31 and movable wedge 35, which is fixed to diaphragm 36. Pressure upstream of the main Venturi section 5 acts on the underside of diaphragm 36 and ambient air acts on the upper side. Spring 42 biases the wedge member upwardly. The depression in the region between Venturi sections 4 and 5 pulls diaphragm 36 downwardly to provide a fast idling speed while the choke is in operation.
