Title: Vacuum chuck
IPC: B65G47/91
Filed: 1974-09-11
Abstract: 1478190 Suction head CORNING GLASS WORKS 11 Sept 1974 [13 Sept 1973] 39549/74 Heading B8H [Also in Division B3] Suction head, for use in moving workpieces, e.g. television tubes, to and from a grinding machine and holding same whilst they are ground, comprises a first support plate 31 connected for rotation with a suspension shaft 38 and having a downwardly depending annular ring 28 with a tapered curved surface 28a and a semi-spherical central surface 33a. A second support plate 23 has an upwardly extending ring 25 with a surface 25a complementary to the surface 28a and a semispherical socket 25d to receive the semi-spherical surface 33a, to form outer and inner ball and socket connections respectively. A spring 44 acts between the support plates to bias same away from one another and thereby force surfaces 25a, 28a into engagement to prevent any pivotal movement between the support plates, and a bolt 46 extends through a slot 25e in the ring 25 and engages with the first support plate to transmit any rotational movement transmitted to the first support plate by the shaft, to the second support plate. A resilient cup 13 is clamped to the second support plate and a pad 21 is bonded centrally to the cup. The pad has radial grooves 21b communicating with an axial bore extending through the head and in communication with a vacuum source. In operation the head is placed on an article and suction applied to the cup to grip the article. The article is then transferred to a grinding machine whereat downward pressure on the shaft 38 releases the locking action on the surfaces 25a, 28a and thus allows limited pivotal movement between the second support plate, and hence the article, and the first support plate and the shaft. Futher downward pressure on the shaft separates the surfaces 25a, 28a and allows greater pivotal movement between the plates about the ball and socket connection.

Title: Method of Making Junctions for Semiconductor Devices
IPC: H01L21/263
Filed: 1967-08-31
Abstract: 1,194,048. Semi-conductor devices. TEXAS INSTRUMENTS Inc. 31 Aug., 1967 [30 Dec., 1966], No. 39911/67. Heading H1K. The impurity concentration in a doped region of a semi-conductor body is modified by an outdiffusion process in which the necessary heat is produced by a focused beam of energy such as an electron beam or laser beam. In the preferred technique described the semi-conductor body, in which a doped region has already been formed by a conventional diffusion method, is exposed to an electron beam which is focused on to the previously doped region and causes diffusion from this region into the environment-which is preferably a vacuum. Before such exposure the surface to be exposed is cleaned, and the electron beam itself may be used to facilitate the cleaning-e.g. by rastering the semi-conductor surface with the beam in a vapour etch atmosphere. The out-diffusion modifies not only the concentration but also the distribution of the deposit in the diffused region, and the resulting impurity profile is such that the impurity concentration increases with depth from the surface to a maximum deeper within the doped zone. Such an impurity profile is particularly suitable for the base of a transistor. Fig. 3 (not shown) depicts a transistor in which the base (15<SP>1</SP>) has been formed by the method of the invention and an emitter (17) subsequently diffused into itconveniently by a method also involving the use of a focused energy beam as described in Specification 1,194,049. Having modified the impurity concentration in a given (e.g. N) type conductivity region, the region may be further modified by depositing over the modified region a layer of the same type but different conductivity (e.g. N+) and the focused beam used to diffuse impurity from this deposited layer into the region. Figs. 6 to 8 (not shown) depict successive stages of such a process. Fig. 9 shows a further example in which an N-type body 61 surmounted by an N<SP>+</SP> layer 63 is being exposed to an electron beam 65. This causes out-diffusion from both the layer and the body to provide modified zones 67 and 69 in each of them. The invention is stated to be suitable for use with any semi-conductor material, and numerous examples are given-including semiconductive dielectrics such as titanium dioxide.

Abstract: 1,079,733. Burners. CONTINENTAL AVIATION & ENGINEERING CORPORATION. Oct. 6, 1964, No. 40622/64. Heading F4T. [Also in Division F1] Fuel injection means for delivering either liquid or gaseous fuel to the combustion chamber of an I.C. engine includes a fuel injector provided with a number of fuel discharge ports, some, but not all, of which discharge liquid fuel when the latter is supplied to the injector, and all of the ports discharging gaseous fuel when the latter is supplied to the injector. The invention is described with reference to a gas turbine engine, the fuel injector comprising a rotating fuel slinger 30, Fig. 1, secured to a hollow shaft 10 connecting the compressor 11 to at least one turbine (not shown). The fuel slinger 30 comprises an annular channel-shaped member, which is provided with a central ring of spaced, discharge ports 33 and two lateral rings 34, and which encloses an annular fuel passage 36. A cylindrical portion 35 of the fuel slinger surrounds an annular fuel manifold 40, divided by radially extending walls (not shown) into alternate gaseous and liquid fuel passages 51 and 52 respectively. The two sets of passages 51, 52 communicate with annular headers 44, 43, respectively, which may be supplied with gaseous or liquid fuel respectively through conduits (47), Fig. 2 (not shown), 45 respectively. If liquid fuel is delivered to the annular fuel passage 36 through orifices 56, then a radially extending flange 57, carried by the manifold 40, ensures that the liquid fuel is discharged through ports 33 only. If gaseous fuel is delivered to the annular fuel passage 36 through orifices 55, then it is discharged into the combustion chamber 12 through both ports 33 and ports 34. The cross-sectional area of each port 33 is smaller than that of each port 34, and the total cross-sectional area of all the ports 33 is smaller than that of all the ports 34. In two further embodiments, Figs. 4 and 5 (not shown), liquid or gaseous fuel is supplied to the fuel slinger through the hollow engine shaft, manifold assembly 40 being dispensed with. A flange having a similar function to that of the flange 57 of Fig. 1 is carried by and rotates with the fuel slinger. In Fig. 4, a fuel metering device (150) is shown.

Abstract: 1440240 Automatic voltage control SONY CORP 30 Aug 1973 [7 Sept 1972 11 Sept 1972 16 Sept 1972] 40919/73 Heading G3R [Also in Division H2] In a power supply system (e.g. for a TV receiver) capable of operating from A.C. and D.C. supplies, a first input terminal 21 for A.C. supply 1 is connected via a rectifier 6 and first chopper 7a to a first primary winding 5a1 of a transformer 5. A second input terminal 18 for D.C. supply 15 is connected via a second chopper 7b to a second primary winding 5b of transformer 5. The output of the secondary winding of transformer 5 is rectified at 8 so as to provide the required D.C. output. The number of turns on the transformer are selected so that the secondary voltage is the same independent of which supply is selected.  Operation from D.C. and automatic voltage control. As described, a TV receiver has an internal battery 15 connected via plug 17c and socket 18c and via normally closed switches Sl, S2 to an ONOFF switch 4 which feeds a winding 5a2 of transformer 5. The output is regulated by a chopping transistor 7b, driven at line frequency by a transistor 30 under control of a pulse width modulating monostable multi-vibrator 11. The output of windings 5a2 and 5b is rectified at 8 so as to provide 5OV D.C. for the line deflection stages 31, 32, the D.C. input being added to the upper end of winding 5a2. The D.C. output voltage is compared with a reference via error amplifier 10 and fed to multi-vibrator 11 so as to regulate the output voltage by controlling the duration of conductive periods of chopping transistor 7b. A lower voltage D.C. supply is derived by rectifying at 37 the flyback pulses from the line transformer 35. High voltage for the anode of the CRT is produced at 36. Operation from an external battery 16 may be achieved by inserting plug 20 into socket 21, switches Sl, S2 isolating the internal battery 15. Operation from A.C. supply. Plug 19 is inserted into socket 21 so as to connect the A.C. mains 1 to rectifier 6 and thence via a chopping transistor 7a to a primary winding 5a1 of transformer 5. Relay 33 is de-energized so as to connect the line pulses from transistor 30 to transistor 7a only. Diode 27 completes the output circuit. Starting. When operating from A.C. mains 1 auxiliary transformer 43 gives a voltage surge which is rectified at 44 and passed via diode 45 to the line oscillator 34 and to the pulse width modulator 11 which thus provides control signals for the chopping transistor 7a. When operating from D.C. supplies 15 or 16, a circuit is completed via the ON-OFF switch 4 and a voltage limiter 49 to the line oscillator 34 and pulse modulator 11 which provides signals for transistor 7b. Battery charging. When operating from A.C. mains 1, relay 47 is energized so as to charge the internal battery 15 from rectifier 48.

Abstract: 1,138,219. Liquid filter. BRASCO S.A. 15 Sept., 1966 [16 Sept., 1965], No. 41225/66. Heading B1D. A filter element 7 of woven structure is cleaned by a combination of reverse flow of filtrate and scraping by a member 16 of openwork form whose interstices are larger than those of element 7 (Fig. 2, not shown), the scraper being, actuated by the flow. reversal or by means controlling the reversal. In Fig. 1, a flexible woven sleeve 7 is supported by an internal perforate sleeve 6 and surrounded by an open-work metal sleeve 16. Normal inward flow is reversed when a motor driven cam 14 lifts a solids drain valve 11 and sleeve 16 together, the reverse flow being caused because gap 15 offers greater resistance than open valve 11 and flexing sleeve 7 outwards against scraper sleeve 16, which is moved downwards with valve 11 by the liquid flow as cam 14 completes its turn. Sleeve 7 may have a mesh of 0.030 mm., while sleeve 16 has interstices of 0.5 mm. and a movement of at least 0.5 mm. In Fig. 3 (not shown), sleeve 16 is flexible, stretched, between valve 11 and an upper spring (22) and operates as in Fig. 1. Fig. 4 (not shown) illustrates a similar flexible sleeve 16 whose lower end carries a disc (25), partly closing a hole in a partition (27) across the housing but not connected to valve 11. When valve 11 is lifted the flow of liquid to the sludge drain urges disc (25) downwards to effect the scraping action and spring (28) subsequently lifts the scraper 16 again. In embodiments not illustrated the scraper may rotate about' a cylindrical filter element, or both scraper and filter element may be flat.
