Title: Improvements in or relating to processes for the productions of thin layers of metallic or semiconductor materials on carrier plates
IPC: C30B31/02
Filed: 1965-02-22
Abstract: Material is transferred by means of a transport gas at a sub-atmospheric pressure from one surface of a source plate to the adjacent surface of a carrier plate of the same or different material, located parallel to, in heat contact with, and at a higher temperature than, the source plate.  The gas may be Cl2, Br2 or I2, a hydrogen halide, or a halide of the material being transferred or, for transfer of carbon, sulphur or a volatile sulphur compound, and may be diluted with H2.  The material transferred may be Si, B, Ge, Ti, Zr, Hf, Th, V, Nb, Ta, Cr, Mn, Fe, Ni, Cu or U (using I2), or Zr, Ta, Mo, W or Au (using Cl2). A pressure of 10 mm Hg or below is used. The source plate (6) may rest on the carrier (4) or be separated by an annular spacer 100-200 m  thick (7).  The carrier rests on a heater (5) of carbon or SiC heated directly or indirectly.  (See Figs. 1 and 2 not shown).  The carrier may be inert, e.g. SiO2 or Al2O3, for polycrystalline growth, or have the same lattice for monocrystalline growth, and the doping may be the same or different. Selected areas only may be grown. In the Example, n-doped monocrystalline Si plates, which were first annealed at 1200 DEG  C. in H2, were used as source and carrier, and heated to 1100 and 1150 DEG  C. respectively in I2 or SiI4 vapour.ALSO:Material is transferred by means of a transport gas at a sub-atmospheric pressure from one surface of a source plate to the adjacent surface of a carrier plate of the same or different material, located parallel to, in heat contact with, and at a higher temperature than, the source plate.

Patent GB-618583-A (GB)
Title: Improvements in knitting machines
IPC: D04B27/08
Filed: 1942-06-03
Abstract: 618,583. Warp knitting-machines. HANNAY, R. S. E. June 3. 1942, No. 7541. [Class 74(ii)] The needles of a warp knitting-machine are adapted to swing across the path traversed by the warp guides at the same time as they are raised and lowered to complete the formation of the stitches. As described, four rows of warp guides 14 are positioned above the needles 10 and are shogged at the end of each stitch formation. The needles are mounted in a needle bar 16 supported by one arm of a bell-crank lever 17 pivotally mounted on the end of a rocker arm 37. A second rocker' arm 41 pivotally supports a lever 46 one end 46<2> of which slides in a guide 49 pivoted at 51 to the frame of the machine. Two parallel links 48 respectively connect the rocker arms 37 41 and the ends of the lever 46 and the arm 17' of the bell crank lever 17. A connecting rod 43 connected to the end of a crank 44 mounted on a driving shaft 35 is also connected to the end of the arm 17<1> of the bell-crank lever. A link 20 mounted on the connecting rod is attached to a yoke 19 which slides in guides at the ends of the needle bar 16 to raise and lower the tongues 11 of the needles 10. Rotation of the shaft 35 reciprocates the connecting rod and rotates the lever 46 about the pivot point 47 on the end of the rocker arm 41 and also rotates the bell-crank lever 17 about the pivot point 40 on the rocker arm 37 causing the needles to be raised and lowered. The end 46<2> of the lever 46 slides in the guide 49 which pivots about the point 51 causing the rocker arms 41, 37 tc oscillate and move the bell-crank lever and needles in a forward and backward direction. The combination of both motions swings the needles across the path of the guide and at the same time raises and lowers the needles to complete the knitting operation. The parallelogram formed by the links 48, lever 46 and bell-crank lever 17 enables the motion about the pivot point 51 of the lever 46 to be reproduced by the opposite member about a similar point which is arranged to coincide with the last line of knitted loops X of the fabric causing the needles to be raised and lowered and swung about this point. The raising of the needles by the linkage causes the voke 19 to be lowered to withdraw the tongue 11 from the hook of the needles 10 in preparation for the engagement of the yarn by the hooks. As the needles are raised they follow a path c formed by the four eyes of the guides 14 and when lowered they return along the same path to engage the yarn. Alternatively the path of the needles may be different when raised to that when lowered. The sinkers 12 are formed with protuberances 13 which prevent the displacement of the fabric during the operation of the needles. According to the Provisional Specification, the machine may have pile loop forming members.

Title: Automatic air speed control
IPC: B64C11/30
Filed: 1955-03-15
Abstract: 772,316. Automatic control systems for aircraft. COLLINS RADIO CO. March 15,1955 [May 28, 1954], No. 7586/55. Class 38 (4). In a system for maintaining constant airspeed of an aircraft a servomotor operating the throttle of a propelling motor is electrically controlled by a signal dependent on airspeed error and by a signal, dependent on pitch attitude, the magnitude of which is adjusted in accordance with the airspeed selected. As shown, a variable inductive device 30 associated with an airspeed responsive bellows 31 develops a signal which is applied through another variable inductive device 37, a mixer 24, and an amplifier 22 to control a servomotor 16 adjusting a throttle 10. A potentiometer 18 coupled to the throttle provides a follow-up control signal. An integrator 42 introduces an integral component of control. A signal dependent on pitch attitude is developed by a variable inductive device 47 associated with a gyro vertical 43 and is applied through another variable inductive device 51 and a potentiometer 57 to control the servo-. motor. The desired airspeed is obtained by adjusting inductive device 37 by a knob 41 which also adjusts inductive device 51 and potentiometer 57 so that the pitch responsive control signal is suited to the airspeed. Potentiometers 18 and 57 may be graded to give desired characteristic response.

Title: Improvements in or relating to Fabrics for Aircraft.
IPC: B64C3/26
Filed: 1918-05-09
Abstract: 128,690. Sage & Co., F., and Feary, N. A. T. N. May 9, 1918. Reinforced paper; compound paper.-Fabrics for aeroplanes are partly or essentially composed of cork and are preferably made up of a flexible covering material such as paper or muslin, a woven wire reinforcement and fragments of cork, with a binding-medium such as a solution of casein. Comparatively small sheets of the fabric may be made on a table by hand. A sheet of paper is laid on the table and brushed over with binding material; the woven wire is then applied and cork dust sprinkled on. Another sheet of paper, sprinkled on one side with formaldehyde solution, is applied to the exposed wire and cork dust, and the whole is consolidated by hand pressure with a rubber-covered roller. When dry, the sheets are impregnated with boiled linseed oil, oil varnish, or oil varnish diluted with driers &c. in a pressure chamber under pressure of about 50 lbs. to the square inch, and finally coated with suitable waterproof material such as boat varnish. Fig. 2 shows an apparatus for producing continuous lengths of the fabric. A web of paper b' is fed from a roll f over a table d by an endless woven-wire band e, and casein solution is applied to its upper surface by brushing, or by a duct or roller. The woven wire a is fed from a roll a<1> and cork dust from a hopper g, which is constructed, as shown in Fig. 3, with a double wovenwire sieve bottom g<1>, g<2>, the latter of which is reciprocated. An upper layer of paper b, drawn from a roll f<1> and sprinkled with formaldehyde solution, is then applied over the cork dust, the whole being consolidated by pressure between the woven-wire band j running round rollers h<1>, h<x>, and the rubber band i running round rollers h<1>, h<1x>. The fabric then passes through a drying tunnel k over, but not in contact with, a metal plate k<2> heated by gas jets k<1>. After leaving the rollers h<x>, h<1x> the fabric may pass between several additional pairs of squeezing rollers, the upper ones being steam-heated so as to dry the fabric at the same time. The bands e, j are preferably of phosphor bronze wire. Any other binding- medium which will be waterproof and non-inflammable when dry may be used in place of the casein solution. A suitable casein solution is composed of casein 1 oz., borax 3/20 oz., water glass 1/2 oz., tannic acid 1/100 - 3/100 ‹oz., and 7 oz. water, and a small proportion of formaldehyde may be mixed with the solution, but is preferably used in conjunction with the binding medium as described above. According to the Provisional Specification, the casein solution made up as indicated above, with the addition of castor oil /10 oz., is mixed with the cork dust to form a plastic composition, and the compounded fabric is subjected to the fumes of formaldehyde. The surfaces of the fabric may be coated with a casein mixture, fixed by formaldehyde or aluminium acetate, and then with waterproof paint, &c., and with coats of oil colour and enamel.
