Title: Dampening system for printing presses particularly offset printing prosses
IPC: B41F7/40
Filed: 1977-10-25
Abstract: The damping device for printing machines has means for engagement and tripping. In this case, the engagement and tripping mechanism is designed such that the metering roller (5) is tripped out of phase with the damper roller (7). In this case, the device is designed such that the damping film present between the damping distributor (6) and the damper roller (7) and between the damping duct roller (4) and the metering roller (5) is not destroyed when the device is tripped. <IMAGE>

Abstract: 1,197,829. Extruded frozen confections. ESKIMO PIE CORP. 23 Sept., 1968 [27 Sept., 1967], No. 45053/68. Heading A2B. [Also in Division B5] A fancy-shaped, multi-hued frozen confection is made by extrusion through a nozzle 13 which comprises a die plate 25 having a fancy-shaped cut-out 26, partions 27, 28 and feed tubes 19 which depend into nozzle 13 through a cover plate 16. Die plate 25, the partitions and feed tubes are replaceable so that confections of different shape may be produced. As shown, partitions 27, 28 divide a Santa Claus figure into four areas, the feed tubes being distributed one to each area, Fig. 4, the tube enclosed by both partitions dispensing a differently coloured, and possibly flavoured confection to the other three. The downstream ends of tubes 19 are closed apart from three equi-length slots 24, the flow thereby being initially radial. Baffles 30, 33 are provided. Die plate 25 is relatively thick and preferably of plastics, e.g. polyacrylate. The extrudate is cut by wires (12), Fig. 1 (not shown), and the slices fall on to a conveyer (11). In a second embodiment, Figs. 7-9 (not shown), the wheels and window of a vehicle, Fig. 9 (not shown), are produced by extrusion of a first confection from a box-like partition (41), Fig. 7 (not shown), via tubes (48-50), and the remainder of the vehicle is produced from a second confection delivered from feed tubes 19 situated either side of box (41).

Title: Improvements in or relating to machine tools

Filed: 1964-11-06
Abstract: 1,120,812. Feed drive mechanisms; machine tool details &c. WILLIAM ASQUITH Ltd. 5 Nov., 1965 [6 Nov., 1964], No. 45270/64. Headings B3B and B3C. [Also in Divisions F1 and F2] In a feed drive for the tool of a machine tool, for example, a drill spindle of a drilling machine, a hydrostatic bearing 16 is used to sense the engagement of the tool with the workpiece and effect a change over from a rapid feed to a slower operating feed. The feed drive includes a worm 14 on a shaft 15 connected to a high speed hydraulic motor 22 at one end and a magnetic clutch 23 at the other end for engaging with the slower feed drive. When the tool engages the workpiece the worm 14 is moved axially along the shaft 15 to either increase the pressure (Fig. 2 not shown) or decrease the pressure (Figs. 4 and 5 not shown) in the hydrostatic bearing 16. This change of pressure is transmitted to a blocking diaphragm valve 24 or blocking spool valve (58) (Figs. 4 and 5 not shown), which operate to block the output from the hydraulic motor 22, (53) which is by-passed via a relief valve 36, (75). When the blocking valves 24 or (88) operate, a micro-switch is operated to effect take-up, via the magnetic clutch 23, of the slower feed drive. Solenoid operated valves, motors, pumps and filters are used in the hydraulic circuitry. A timing device may be used with the said micro-switch to permit the deceleration of the hydraulic motor. To permit the worm 14 to declerate more rapidly than the feed shaft the worm is mounted on a fine screw thread (41) (Fig. 2 not shown), and energy is absorbed in a spring (19).

Title: Decimal to binary conversion
IPC: H03M7/04
Filed: 1970-09-23
Abstract: 1318752 Binary-coded-decimal to binary converter RCA CORPORATION 23 Sept 1970 [24 Sept 1969] 45307/70 Heading G4A The invention relates to a binary coded decimal to binary converter. Decimal data from a keyboard is entered into a shift register in the four most significant stages Bn-Bn-3. When the digit key is released a predetermined number of clock pulses causes data in the register to be shifted. The bits in stages Bn-2, Bo and B-2 are fed to an adder 10 the output of which is fed to stage Bn-3. On entry of the most significant digit of a decimal number, the binary equivalent is entered into stages Bn-Bn-3 On release of the key a number of shift pulses sufficient to move the least significant bit to stage Bo is produced. Since the register previously contained zero the entered number is shifted unchanged. After the next most significant digit is entered the shift pulses are produced. During shifting the connections to the adder cause the digit in stages Bo-Bn-4 to be multiplied by 2 and to be multiplied by 8 and to be added to the digit entered in stages Bn-Bn-3 so that each digit is multiplied by 10 before the next lower significant digit is added to it. The adder may be as shown in Fig. 2 wherein the AND and OR gates and inverters shown perform the logic operations

In the cylindrical structure shown, which produces a substantially uniform field throughout the central region 80c, the oppositely radially magnetized annular permanent magnets 76 and 78 are coupled at their outer peripheries by a cylinder 74 of low reluctance material, e.g. cold rolled steel; the magnetic annuli 84 may be of iron, and the non-magnetic annuli 82 of aluminium or air; and the end regions are separated from the central region by intermediate regions 80b formed by one non-magnetic spacer and a magnetic member of increased axial length. Reference is made to the use of an electromagnet rather than a permanent magnet, and a U-shaped, rather than a cylindrical structure, is also disclosed (Fig. 5, not shown). As shown, the structure may provide the focusing field for a proximity focused image intensifier tube which incorporates a channel electron multiplier element 96.

To move the polarizer to its circularly polarized position for example, the contacts 3, 4 of switch 2 are moved to the position shown to energize the relay 8 whose contacts 12 close to energize the motor 13 through the switch 20. When the polarizer has attained its circularly polarized position, the switch 20 changes over to switch off the motor and complete a circuit from source 1 to members 15 ... 18 via members 6, 12, 14, whereby the diode 16 conducts to energize the relay 18 and so provide an indication of the state of the polarizer.

Abstract: 1,273,576. Explosive compositions. IRECO CHEMICALS. 23 Sept., 1969 [1 Oct., 1968], No. 46720/69. Heading C1D. In order to control the density of slurry explosive being pumped into a deep bore-hole, a gas generating, substance is added to the slurry at a controlled rate such that the proportion of gas generated decreases from the bottom to top of the bore-hole. For example, small bubbles of oxygen are introduced by adding hydrogen peroxide together with a decomposition catalyst to a slurry containing ammonium nitrate, sodium nitrate, water, guar gum, borax, and an insoluble sensitizer and/or fuel, such as gilsonite, bituminous coal, sulphur, or aluminium powder. Suitable catalysts are KI, MnO 2 , ferric nitrate, and ferrous sulphate, with or without manganous sulphate and hexamethylene tetramine. The rate of introduction of hydrogen peroxide may be reduced grandually as filling of the bore-hole proceeds. Introduction of a higher proportion of aerating agent into the slurry at the bottom of the bore-hole counteracts the increase of density and loss of sensitivity due to the pressure head of the slurry and the stemming. In place of the hydrogen peroxide, a CO 2 -producing agent may be added. Apparatus for pumping the slurry into bore-holes and regulating the amount of gas generating substance is described with reference to drawings. Specification 1,273,577 is referred to.

The polarization of a plane polarized wave is transformed by a Faraday rotator 6 and a ferrite phase-shifter 5. The direction of polarization of a plane wave E A , fed from a rectangular waveguide 1 to a circular waveguide 2, is rotated through an angle α by means of an adjustable ferrite Faraday rotator 6 having field coils 3. Thereafter, the rotated wave suffers a phase shift in a ferrite shifter 5 of the type controlled by a transverse saturation field H 0 .Components of the rotated wave parallel respectively to the transverse axes OX, OY undergo different phase-shifts whereby, in general, an elliptically or circularly polarized wave is produced by the phase-shifter. However, for values of α equal to zero or to multiples of #/2, the output is a plane-polarized wave shifted in phase by an amount depending upon whether the multiple is odd (wave parallel to OY) or even (wave parallel to OX).
