Title: Multiple disk files
IPC: G11B5/55
Filed: 1975-10-10
Abstract: 1494967 Magnetic disc recorder INTERNATIONAL BUSINESS MACHINES CORP 10 Oct 1975 [6 Jan 1975] 41577/75 Heading G5R In an accessing mechanism for a magnetic disc file S, the access arm 16 carrying magnetic head 18 is moved in a direction having a component parallel to the disc file axis and towards and away from the file by a single drive motor M. The motor M, which can be a stepping motor, drives a lead-screw 11 which moves a carriage 10 in the directions A, B towards and away from the file. The carriage 10 carries an access arm carriage 12 which is movable along guideways 14 in directions D, C inclined as shown to directions A, B. The carriage 12 carries arm 16 and a pair of rack members 42, 58 with oppositely directed teeth which coact respectively with pawls 32, 50 pivotally mounted on carriage 10 and formed with teeth 38, 54 shaped to co-operate with their respective tracks. The teeth of the pawls are resiliently urged into engagement with their racks by respective spring members 36, 52. On movement of the carriage 10 in direction B the pawls 32, 50 are respectively engaged by cam members 62, 70 and pivoted anticlockwise to remove their teeth from the racks. Spring 46 now moves carriage 12 to the upper end of guideways 14 thereby raising access arm 16 to a position above the uppermost disc in the file. Having passed over cam 62 pawl 32 now returns into engagement with rack 42 and on continued movement of the carriage 10 a part 24 of carriage 12 engages a stop arm 26 after which motor M continues driving carriage 10 for a predetermined distance thereby moving carriage 12 down guideways 14 with pawl 32 rotating over the teeth of its rack until the end of arm 16 is opposite the gap above the required disc. The rack is dimensioned such that each tooth corresponds to a specific disc in the fill. The carriage 10 is now driven in the direction A with carriage 12 held in position by pawl tooth 38 against the restoring action of spring 46. The pawl 32 is not affected during this direction of movement as cam 62 pivots out of engagement and as pawl 50 leaves cam member 70 it pivots so that itsteeth 54 engages rack 58 to secure the carriage 12 against movement in either direction along guideways 14. The carriage is driven in direction A until the required track on the selected disc is accessed.

IPC: E21B49/00
Filed: 1965-10-06
Abstract: 1,120,124. Boring earth &c. UFIMSKY NEFTYANOI NAUCHNO-ISSLEDOVATELSKY INSTITUT. 6 Oct., 1965, No. 42387/ 65. Heading E1F. A formation tester has a hydraulic delay device controlling movement of a valve assembly from a lower position in which the flow of formation fluid to the tubing above the tester is blocked, through intermediate positions in which the flow is permitted, and to an upper position in which the . flow is blocked. The assembly comprises a rod 8 having a valve-head 9 engaging seats 10, 12 in the upper and lower positions respectively to close channels 13 leading to the tubing above the tester. When a valve in the tester tail pipe (not shown) is opened the pressure of the formation fluid on the rod overrides the pressure of gas in a chamber 3 to move the assembly at a rate determined by the delay device which comprises a piston 16 fixed to the rod and moving in an oil filled chamber 4. In a modification (Fig. 2-5, not shown) the channels are initially closed by a sleeve valve (19) and after this is opened by the formation pressure the channels are blocked for a period before the formation fluid flows through the channels by the valve-head engaging a cylindrical surface. A pressure recorder may depend from the tail pipe.

Abstract: 1497499 Semi-conductor devices INTERNATIONAL BUSINESS MACHINES CORP 13 Oct 1976 [28 Nov 1975] 42466/76 Heading H1K A localized dielectric region is produced in the surface of a silicon substrate by forming a corresponding region of porous silicon in the surface, completely oxidizing the porous silicon at a high temperature so that the oxide extends above the substrate surface and then raising the temperature further for a time sufficient to densify the oxide so that its surface is flush with that of the substrate. In the described embodiments, in which the dielectric region is used to isolate sections of an epitaxial layer overlying heavily doped buried regions on an N type body, a masking layer of thermal or pyrolytic silicon, optionally coated with silicon nitride, is apertured at the site of the dielectric region and the exposed silicon diffused or implanted with acceptor impurity to form a P+ network extending to the body. The network is then subjected to anodic action in hydrofluoric acid to produce 40-80% porosity, and the porous silicon heated in steam or oxygen at 970 C. to oxidize it and optionally form a dense silica layer beneath it. After densifying by heating, e.g. at 1150 C. or above in nitrogen or other inert gas or in an oxidizing gas, transistor structures are conventionally formed in the isolated sections of the epitaxial layer. Typically a strip of densified porous oxide is formed within each section to provide a laterally isolated collector contact region.

Title: Aircraft simulation
IPC: G09B9/08
Filed: 1969-08-27
Abstract: 1,240,629. Aircraft simulator. SINGER-GENERAL PRECISION Inc. 27 Aug., 1969 [9 Sept., 1968], No. 42659/69. Heading B7W. [Also in Division H3] A fixed-base aircraft simulator is provided with an apparatus for producing random electrical signals representative of rough air and the output from this is fed to analogue computers which continually calculate the flight equations for the particular type of aircraft being simulated, and which control motor means of the simulator to produce the desired effects of pitch and roll. The output from a white noise generator 11 is fed to two mixers 12 and 22 which are also fed by the outputs of a source of polarity alternating signals, such as a multivibrator 14. The mixer 12 feeds a first channel consisting of a low pass filter 15 having a cut-off at, say, 0.1 Hz and a high pass filter 16 having a cut-off at, say, 0.01 Hz. The emerging band of low frequency random vibrations, represented by curve C is fed via a terminal 17 to the computer controlling the pitching motion of the simulator. In a second channel, fed by the mixer 22, a low pass filter 25 has a cut-off at, say, 5 Hz, and a high pass filter 26 a cut-off at, say 0À01 Hz, and the resulting frequency band represented by curve F feeds the airspeed indicator via terminal 27, and also feeds a further low-pass filter 28 with a cut-off at, say, 0.1 H 2  (see curve G), whose output is fed via terminal 29 to the computer controlling rolling motions. The circuitry of the mixers 12 and 22 (Fig. 2, not shown) is such that each one is shortcircuited during alternate half cycles of the vibrator 14, so that the outputs from the mixers are alternate periods of silence and random noise, illustrated by curves A and D. The energy output of the source 11 in the very low frequency range required is small but by combination with the output of the vibrator 14 noise of these frequencies is produced from the higher energy random noise with frequencies near the operating frequency of the vibrator.

Title: Improvements in or relating to handling pallets
IPC: B65D71/02
Filed: 1963-10-29
Abstract: 1,068,735. Load-handling pallets; packagings. Oct. 29, 1963 [Oct. 29, 1962], No. 42664/63. Headings B8C and B8H. A pallet consists of a load support 1 with two parallel beaded edges 2, 2a which can be slid into slotted tubular members 3, 3a so as to be liftable by a fork whose tines fit into the tubular members. The support 1 is a sheet of rigid or flexible material which may be made up of layers of different materials such as plastics, metal foil and paper. The beads may be folded-over portions of the sheet edges, or rigid members secured to them, or a combination of both. Figs. 4 to 15 (not shown) depict examples of all three kinds. The tubular members may be slotted along their whole length and be substantially as long as the sheet, as in Fig. 3, or slotted for part only of their length and extend beyond the sheet, as in Fig. 16 (not shown), which also shows the slot increasing in width towards its open end. It is also possible to use a composite construction comprising a slotted tube which just accommodates the bead secured to a larger unslotted forkreceiving tube; Figs. 19 to 25 (not shown) depict several forms of this composite tube construction.  For lifting heavy loads the structure may be given greater rigidity by joining the pair of forkreceiving tubes to a rigid transverse beam 38 (Fig. 31, not shown). For lighter loads a single pair of tubes-suitably multiply slotted-may carry more than one beaded sheet.  Goods may be stored on the sheet portion alone, the tubes being fitted over its beaded edges whenever lifting is required. They may also be stored on pallets consisting of the sheets fitted with the tubes, in which case it is convenient to support the pallets on stands (Figs. 29 and 30, not shown) with corrugated surfaces for locating the tubes. A package for a load such as a number of sacks may be formed from a flexible beaded-edged sheet in combination with a single lifting tube having two parallel slots, or two parallel slotted bead-receiving members fitted to it. The flexible sheet is wrapped around the load and its beaded edges fitted in the two slots (Fig. 27, not shown).

Abstract: 990, 536. Photo-electric measuring systems. BARNS ENGINEERING CO. Nov. 12, 1962 [Dec. 20, 1961], No. 42695/62. Heading G1A. The invention relates to a scanning arrangement which is described in connection with apparatus for determining the width of an object. Fig. 1 shows apparatus for measuring or monitoring the width of extruded hot glass tube 13, use being made of a fixed detector 1 responsive mainly to infra-red wavelengths at which the glass is opaque. Suitable detectors are lead selenide cells or thermistors with a suitable filter. The detector 1 is within, and views along a radius of, a revolving drum 4 carrying internally a plurality of mirror segments 5. Between the detector and drum is an apertured mirror 2 receiving radiation from a germanium lens 12. Rotation of the drum causes the field of view of the detector to be scanned repeatedly across the tube and the background in either side of it as the tube travels lengthwise. The width of the tube is derived from the detector output and calibration can be achieved by raising mirror 14 to deflect the scanning field of new via mirror 15 to a standard tube maintained at a suitable temperature. Use of a chopper incorporating mirrors to enable the test sample and reference tube to be viewed alternately is mentioned. If the background radiates more strongly than the object itself obstruction of the radiation (normally visible) by the object can be used to determine the objects width. Specification 922,035 is referred to.

Abstract: 1,149,059. Caps for bottles &c. D. H. TROTT. 26 Sept., 1966, No. 42930/66. Heading B8T. A dispensing cap for a bottle &c. comprises a spout 21 and a surrounding rotatable and axially movable tube 24, a valve 40 closing the end of the spout pivoting away to an open position when the tube 24 is turned. The valve 40 is connected by a lever portion 35 to a twodiameter cylindrical bearing spigot 36, 37 journalled in a recess 34, 39 in a support 28 fast with the tube 24. Cam followers 43, 45 at the bottom of the bearing spigot 36 engage on opposite sides of a small fin (48), Fig. 8 (not shown), at the top of the spout 21, Fig. 3, from which a cam slot 51 extends. A pin 50 in the tube 24 slides in a cam slot 52 . . . 54 around the main body 14 of the spout 21. When the valve 40 closes the spout 21, the pin 50 lies at the end of the section 52 of its cam slot, as shown. On initially turning the tube 24 to open the valve 40, the pin 50 slides along the cam slot section 52 and constrains the tube 24 &c. to slide axially up the spout 21. Thus the valve 40 is lifted off the end of the spout 21, Fig. 4 (not shown). On further turning of the tube 24, the pin 50 slides along the flat cam slot section 53, which prevents the tube 24 from moving axially relatively to the spout 21. At the same time, relative rotation between the tube 24 and the spout 21, and the engagement of the cam followers 43, 45 at the base of the bearing spigot 36, 37 with the small fin (48) on the spout, swings the lever portion 35 and the valve 40 to one side, out of alignment with the spout, Figs. 5, 9 (not shown). On further rotation of the tube 24, the pin 50 slides down the inclined cam slot section 54, drawing the tube down the spout 21, Fig. 6 (not shown). Simultaneously, the cam follower 43 slides down the cam slot 51 on the spout 21. The cam slot 51 is so shaped that the lever portion 35 and the valve 40 are constrained to remain at one side of the spout 21. As shown, the dispensing cap is screwed on to the neck of a flexible squeeze tube 10. Alternatively, it may be an integral part of a container.
