Title: Method of manufacturing lamellar composites
IPC: C30B13/00
Filed: 1973-10-29
Abstract: 1405027 Crystalline lamellar composites PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES LTD 29 Oct 1973 [1 Nov 1972] 50227/73 Heading B1S A body of lamellar composites is made by preparaing a body of a non-crystalline solid single phase material i.e. amorphous or vitreous, which upon decomposition completely decomposes into at least two exclusively lamellar phases growing juxtaposed with a discontinuous front in the non-crystalline phase and passing through the body unidirectionally a temperature gradient which decomposes the body into two or more crystalline phases. The non-crystalline solid phase may be formed by rapid cooling of a homogeneous melt or by vapour depositing or cathode shuttering materials onto a cold substrate. The body may be formed in a mould. Suitable materials for forming the body are a mixture of Bi 2 O 3  and B 2 O 3 , a entectic mixture of Ca(NO 3 ) 2  and RbNO 3  and a mixture of ZnCl 2  and KCl. In the examples the composites obtained have lamellar spacings ranging from 0.5 to 2Ám.

Abstract: 1525750 Cameras SUNPACK KK 22 Dec 1975 52395/75 Heading G2A A camera has two sets of non-numerate symbols one set being used to set the diaphragm aperture for daylight exposures and the other being used to set the diaphragm aperture for flash exposures operation of a flash power switch 26 causing only the appropriate set to be displayed. As shown the daylight set indicates weather conditions and the flash set indicates object distance. As shown in Fig. 1, the switch 26 is off and the weather pictures are in alignment with a window 71. Movement of a member 50 pivots diaphragm 40 via a pin 57 and at the same time moves the weather pictures under window 71. When the most appropriate picture is visible adjustment is stopped. If a blank picture becomes visible, this is an indication that a flash exposure is necessary. Movement of switch 26 to energize the flash also moves a changeover lever 32 leftwards to cam the symbol carrier 54 against a spring 58 whereby the object distant pictures are visible through window 71. Member 50 is again operated manually to adjust the diaphragm until the most appropriate picture becomes visible. In Fig. 3 (not shown), the weather and object pictures are carried by different members which are brought into and out of overlapping relation to make one or other of them visible depending on whether or not the flash switch is closed. In Fig. 4 (not shown) two windows (471, 472) overlie the two rows, one window being blocked according to whether or not the flash switch is closed.

Webs la, 2a are fed intermittently by a belt feeder 27 and power-driven rollers through at least one antistatic device 16 which eliminates static charge and co-operates with vacuum means for withdrawing dust. Web 2a only is passed through a piercing station 17 comprising punches 18 or hot air jets for forming slots 8 to form pocket openings. At this stage the trailing edge (10) of each slot 8 may be raised or curved and strips portions (14) overlying the pockets may be raised out of the plane of the web 2a by cold forming dies. Pin holes 12 and/or notches 13 may also be formed.

Abstract: 1,143,148. Integrated circuits. RAYTHEON CO. 22 Nov., 1967 [1 Dec., 1966], No. 53235/67. Heading H1K. A semi-conductor structure consists of an active semi-conductor device held within a semiconductor frame by beam leads which are bonded to the oxide coating of the frame; the device is separated from the frame by an air gap. As shown, two bodies 14 each containing a single transistor are mounted in a single aperture of a frame 10. In addition to the emitter, base, and collector leads 18 of the transistors which bond the bodies to the frame, there is a further beam 18b linking the two bodies for added strength though insulated from them by their surface oxide films. (A completed unit may have several apertures each containing an active device or devices). The structure shown may be made from a (100) N<SP>+</SP> silicon wafer 22 bearing an epitaxial layer 20 of higher resistivity. This is masked on both surfaces and etched. At the lower surface etching leaves protuberances subsequently delineating the frame. At the upper surface etching produces grooves extending to the N<SP>+</SP> substrate. These are filled by vapour deposited contact metal 40 so that areas of this metal are in conductive contact via the low resistivity body with a temporary electrode 44 used during masked electro-plating of the main metal 18 of the beam. Subsequently, the temporary electrode is removed and the oxide pattern 42 used to define areas at which preferential etching along the (111) planes removes silicon to leave the frame and transistor bodies, the upper surface of the structure being masked with silicone rubber (46) during this step.

Abstract: 1336001 Echo-sounding JAPAN RADIO CO Ltd 9 Nov 1970 [8 Nov 1969] 53290/70 Heading H4D [Also in Division G4] A variable frequency clock generator reads the output of an a-d converter, connected to an echo sounder detector, into a memory and a fixed frequency clock generator reads the stored signals out to a visual display. A paper chart recorder has a stylus 10 mounted on an endless band 7, which carries a contact 9. When contact 9 engages contact 5 a pulse is transmitted from generator 3 and gates 13 and 17 opened by bi-stable 12. Signals from detector 2 are quantized and coded by a-d converter 16. The resultant digital signals are read into shift register 18 via gate 17. When the register is full, a pulse appears at its output 21 which resets bi-stable 12 inhibiting further reading in. When contact 9 engages contact 6 monostable 22 opens gate 23 long enough to enable generator 24 to read out the stored information to the chart recorder. The frequency of generator 14 is variable to enable variation in the range of echoes stored in register 18, which may be a single shift register into which the coded signals are read sequentially or two parallel shift registers each storing one bit of the two-bit code. The invention is described as applicable to fish-finders, the position of the coded signal in the shift register determines the shoal depth and the code represents the echo amplitude both of which are transferred to the chart record.
