Patent GB-1517751-A (GB)
Title: Microcomputer terminal system
IPC: G06F13/12
Filed: 1975-06-26
Abstract: 1517751 Generating video displays ZENTEC CORP 26 June 1975 [27 Feb 1975] 27061/75 Heading H4T [Also in Division G4] A video display 45, Fig. 1, is coupled to a memory 50 via two series-connected shift registers 150, 151, Fig. 6 and video circuits 52 which convert character data from shift register 151 to video signals. Shift register 151 recirculates to repeatedly supply the sequential character codes of a display row to a dot pattern character generator 152 in order to build up a row of characters comprising a plurality of scan lines. While one row of characters is being displayed, another row is entered into shift register 150 and is transferred to shift register 151 instead of the recirculating row while the last scan line of the current row is being displayed. This arrangement reduces the demand made on the system bus 40 and on the memory 50. The memory 50 is divided into two sections. A register section includes cursor row and column address registers loaded by a microprocessor 41 and read by the video circuits, and a keyboard input character register read by the microprocessor. A video display section of memory 50 has a byte for each display character position and is loaded by the microprocessor and read by the video circuits. A character entered from the keyboard is removed from the input register by the microprocessor and is stored at the location in the memory display section corresponding to the current position of the cursor. The microprocessor has a local (programmable) ROM 42 and when transfers of information are taking place between this memory and the microprocessor, the system bus 40 is freed for use by I/O devices such as a disc store 203, computer 200, communication line 201 or printer 202. Data may be read from or written in non-contiguous locations in memory 50 and may be written in or read from contiguous locations in the auxiliary store 203. Display details. Each character is formed from a 10 Î 10 dot matrix, vertical legs being formed by two or more columns of dots to improve brightness. Special control character functions used include cursor relocation, movement or erasure of display segment and special display effects. Certain keyboard-entered characters can be automatically repeated by holding down the associated key. The cursor-row and column address is entered into a cursor generator 155 which inserts additional video signals into the dot pattern signals to produce a cursor display at the required display position. The brightness of the display can be varied by chopping (pulse width modulating) the dot signals in accordance with the special effects control characters which are decoded at 156 and held in a register 157 to have effect on all subsequent data characters. An additional memory and video circuit may be provided to produce a display simulating a form on which data may be entered. Timing and synchronizing signals are derived from a crystal oscillator feeding cascaded counters, Fig. 5 (not shown).

Title: Milling machine
IPC: B23Q5/26
Filed: 1957-08-28
Abstract: 810,347. Copy-milling. LUCY, W. F. G. Aug. 28, 1957 [Sept. 10, 1956], No. 27130/57. Class 83 (3). A milling-machine comprises a cutter 27 slidable in a direction normal to the direction of reciprocation of a table 12, and two hydraulic cylinders 37, 40 extending in the same directions and connected in a closed circuit to cause the cutter always to lie, at one end of the reciprocation of the table, on a conical surface 55. A pair of ball-ended cutters 27, individually rotated by motors 25, are mounted on arms 23, 23a pivoted to a bracket 21 and having followers engaged in cam-grooves 19. The bracket 21 is reciprocated by an hydraulic device 29, 30. In operation, a workpiece WP is located on the table 12 by pins 50 so that a strut 51 to be machined lies in the direction of reciprocation of the table. Switches are closed to start a pumpmotor and to energize an electric control circuit and to start the motors 25. When a further switch is actuated by the operator, the cutters are fed rapidly down to the work by the piston 30, until a dog 123 actuates a switch MS1 to cause rightward traverse of the table 12 to bring the cutters adjacent the vertical wall 53. A dog 54 on the table then operates a switch MS2 to cause a slow down-feed of the cutters, the speed being determined by a hand-set valve in the hydraulic circuit. The down-feed is determined in duration by a hot-wire switch. The table then travels left and the cutters take a cut along the top of the strut until the dog 54 actuates a switch MS3 to return the table. At the end of the return-stroke, a further cutterfeed occurs, followed by a cutting-traverse. As the central hub of the work is conical, the traverse strokes of the cutters must be successively reduced by moving the switch MS3. To this end, the switch MS3 is mounted on a piston 56 in the cylinder 40 connected in a closed circuit with the cylinder 37, having a piston 36 which is contacted by a rod 31 projecting from the piston-rod 30. Thus, as the cutter-slide moves downwardly, fluid is forced from the cylinder 37 into the cylinder 40, to progressively move the switch MS3. The cutters are retracted when the dog 123 actuates a switch MS5, and the machine-cycle is stopped when a switch MS4 is actuated.

Abstract: 1,048,633. Dispensing liquids by gaseous pressure. CARTER-WALLACE Inc. July 11, 1963 [Aug. 2, 1962], No. 27508/63. Heading F1R. In a device for heating a lather, such as shaving cream lathers and shampoo lathers, emerging from an aerosol container, the lather is delivered from the container to an outlet via a thin wide enclosed chamber heated by immersion in a body of hot water. A heating device, Fig. 4, is mounted on the top of a conventional aerosol container, after the combined spout and valve button have been removed from the latter, with a plunger 20 of the device located over the original valve actuator 9 and a flange 19 gripping the top of the container. Depression of a button 17 causes the plunger 20 to force the valve actuator 9 downwards as shown, and thereby move the passages 7 in a preferably rubber diaphragm 5 clear of an obturating sleeve 8. Lather thereby escapes through passages 7, 10, 11, 26, 42 and a nipple 44 to a thin wide chamber 38 of a cylindrical heat exchanger 34 formed by two cylinders 36, 37. The walls of the chamber 38 need not be parallel as shown. The passage 26 meters the lather flow to 4-8 c.c./sec. A body 12 supports the heat exchanger 34 in spaced relation to its bottom and side walls to enable hot water, supplied at the top of the body 12, to surround the heat exchanger 34 and thereby heat the lather passing therethrough to a nipple 37A and delivery spout 32. The heat exchanger is positively positioned by the "snap-in" action of nipples 37A and 44 into recesses in the body 12 and an arm 15 of a housing 14. The latter is preferably friction fitted over a sleeve 21 of the body 12. The body 12 is of plastics material such as linear polyethylene, polypropylene and polystyrene, and the heat exchanger 34 may be of non-metallic material but is preferably of metal, such as steel or aluminium. The heating device may be integral part of the aerosol container. In an alternative embodiment, Fig. 6, a similar heating device is mounted on the side of a complete conventional container 1 by a clip 52, and a tube 42<SP>1</SP>, communicating with the interior of the heat exchanger, is connected to the delivery spout of the container 1. Alternative forms of the heat exchanger are shown in Figs. 7 and 8 (not shown). One form has two or more horizontally-spaced rectangular passages of narrow cross-section arranged vertically and connected in parallel with respect to flow, and a second form has a single passage of narrow cross-section arranged horizontally. The second form may be heated by periodic immersion in a mass of hot water prior to discharge of the lather. Various dimensions of the heating device are given in the Specification.
