Abstract: 1,031,824. Photographic vesicular materials. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 6, 1962 [Feb. 23, 1962], No. 46151/62. Addition to 1,031,823. Heading G2C. Vesicular images are produced by imagewise exposing a film containing two vesicular materials in a polymeric binder so that one of the materials produces a gas, relaxing the material to form invisible bubbles (e.g. a maximum diameter of 0. 5 microns) and then uniformly exposing the film so that the second material produces a gas and then relaxing the film to produce a visible bubble image.

Abstract: 988,530. Photographic composing-machines. NIPPON ELECTRIC CO. Ltd. Dec. 7, 1962 [Dec. 8, 1961], No. 46236/62. Drawings to Specification. Heading B6W. Images of characters produced on the screen of a cathode-ray tube are transferred by optical means on to a continually fed record strip, an electrical control system being arranged to move a mirror in the optical system so as to displace the image horizontally and vertically, while at the same time controlling the strip feed motor so as to vary the feed speed in accordance with the characters and blanks being transferred, in such a way that the character images are formed on the strip in lines across the strip. A delay circuit utilized when a character is to be transferred is by-passed when a blank occurs, resulting in rapid movement of a scanning device over the character display device so that the time required to print a character is not consumed when a blank occurs.

Abstract: 1,159,177. Spiked plates. A. C. SANFORD. 13 Oct., 1967 [3 Nov., 1966], No. 46746/67. Heading F2H. [Also in Division E1] A spiked metal plate for connecting metal web members to wooden chord members in a composite wood and metal building truss has teeth 33 which are punched out in pairs to form columns and rows of elongate slots 136, the rows being vertically aligned (as shown) or staggered. The teeth are stepped on one edge (35), and diverge from and then converge towards the other tooth of each pair from the root to the tip of the tooth. The die also crimps each tooth so that the outer surface 41 of the root is generally arcuate. The dishing is along a crimp line 42 (see Fig. 9) which is inclined with respect to the outwards direction of the tooth, so that the tooth is twisted (Fig. 4, not shown).

Title: Process of Etching Semiconductive Material.

Filed: 1968-10-04
Abstract: 1,187,185. Etching. R.C.A. CORPORATION. 4 Oct., 1968 [17 Oct., 1967], No. 47115/68. Heading B6J. [Also in Division H1] A region underlying a junction spaced from the surface of a semi-conductor body is exposed by oxidizing a predetermined area of the surface of the body to form an oxide layer which is then removed by an etchant which does not attack the semi-conductor and repeating these steps until sufficient material is removed to expose the region. The method is shown applied to manufacture of a transistor from the Fig. 1 structure which has been formed by epitaxial deposition of silicon layers on a substrate 12 of silicon spinel or sapphire. Masking layer 30 is formed by pyrolytically depositing silica overall from siloxane followed by photo-resist and etching steps. The exposed surface 32 is then anodically oxidized to a depth of 700  in N-methylacetamide and the oxide removed by etching in normal hydrofluoric acid, the processes being repeated until exposure of P- type base layer 24 is confirmed by a thermal probe. A larger area mask is then applied and mesa etching effected in a nitric-hydrofluoric acid mixture to expose N + collector contact zone 16. All the masking is then removed and a passivating oxide layer deposited. Emitter, base and collector contacts 42, 44, 46 are then applied through apertures etched in this layer and leads thermocompression bonded thereto. Masking 30 needs to be thick enough as not to be removed by the etchant before layer 24 is exposed.

Title: Method and Apparatus for obtaining a Fluid Sample from an Earth Formation
Inventor: RAUGUST THEODORE A
IPC: E21B49/08
Filed: 1967-10-17
Abstract: 1,184,443. Wells. BORG-WARNER CORP. 17 Oct., 1967, No. 47298/67. Heading E1F. Apparatus for sampling fluid from an earth formation in a borehole comprises a drill pipe 18, landing sub 26, drill pipe 28, reversecirculating sub 32, valve 34, packer 36, and nose 38 with openings 39. A further packer below openings 39 is required if the borehole extends below the formation. Within sub 32 is a cup 44 with splines 45, supporting a lower plug 40 with seals 74, 76, on which rests an upper plug 42 with seals 94, 96. After setting the packer, valve 34 is opened allowing fluid to flow through openings 39, past splines 45, through annular space 63 and aperture 64 to the space between the plugs. Plug 42 then rises to the landing sub, either through the pressure of fluid in the formation, or by traction on a fishing neck 118. Valve 34 is then closed, and the packer released. The string is then raised and pipe 18 removed, to expose the landing sub at the surface. Neck 118 is removed, and a sample collecting pipe replaces plug 124, and a retrieving assembly is screwed into sub 26. This has a screw-down knock-out bar which in the first part of its travel pushes an internal plug below apertures 106, to permit the sample to flow through the plug 42, and then ejects a pump-out bar 110, which falls and strikes a sprung anvil 86 in plug 40, so as to shear the support for a plug 48. The pressure of drilling mud in annulus 30 is then increased, so that plug 48 is forced inwards, admitting mud to below plug 40, causing the plug to rise and the sample to be delivered through plug 42. When the pump-out bar resting on anvil 86 abuts plug 42, the anvil is again depressed, to open a valve in plug 42 allowing mud to flow through the plug and flush out the remains of the sample. In modifications, the bottom plug 40 or the top plug 42 is omitted, the spring not being raised and the sample being discharged through an outlet 22 when the top plug is omitted.

Fig. 6 shows a modification of Fig. 1, wherein a rod 1c is connected at a point of reduced leverage to the throttle-operating lever and slides through a hole in a member 5a connected to rod la. At the point where the rods la and 1b are disconnected by the electromagnet, a stop 1d abuts the member 5a and the throttle may still be operated but increased force will be required. In a further modification, Figs. 8 and 9, the throttle valve of the carburetter is actuated by a lever 19 connected through a detent 12, operated by an electromagnet 4, to a lever 20 biased towards the closed position of the valve by a spring 21a, the lever 19 being biased in the same direction by a spring 22a. The lever 20 is actuated from the vehicle accelerator pedal through a cable 1c passing over a segment 20b. As before, the detent 12 is withdrawn at the predetermined speed and the throttle valve is closed but, to meet an emergency, the accelerator pedal may be further depressed until a roller 26 on lever 20 coacta with a lever 23 also connected to the throttle valve and through which the throttle valve may be actuated. Reference is made to an hydraulic coupling the valves of which are actuated electrically at the appropriate speed limit, and also to a control device incorporating a photoelectric cell.
