Title: Improvements in or relating to packaging machines
IPC: B29C65/00
Filed: 1961-03-15
Abstract: 925,377. Packaging. A. SCHMERMUND. March 15, 1961, No. 9483/61. Classes 94(1) and 94(2). [Also in Group XI] Means for welding or drying adhesive in a packaging machine or for attaching a tear tape to a wrapper include a guide passage having a wall or wall portion of electrically conducting material heated directly by passing a current through it. In one embodiment, Fig. 1, a tear strip 14 is attached to a web 13 of heat sealable material by pressing them, by means of a brush 7 into contact with a directly heated bar 2. The web is fed by rollers 18 and the end of the tear strip is cut to shape by rotary cutters 15, 17. In another embodiment, Fig. 3, a stacker has one fixed wall 124 and three walls 106 adjustably mounted on parallel motion links 111. Each wall 106 comprises a heater tape 101 mounted so that its tension may be adjusted on a support 108 which is pivoted to the links at 112. The links allow adjustment to deal with different sizes of packages 117. In a further embodiment, Fig. 11, a guide channel has heater tapes 201 mounted one on each side of it so that the distance between them may be varied. Means may be provided for temporarily increasing the electric current on starting the machine to initially heat the conductors. A thermostatic control circuit is described.

Patent GB-723970-A (GB)
Title: Frequency selective networks
IPC: H04B1/16
Filed: 1951-04-24
Abstract: 723,970. Automatic phase-control systems ELTGROTH, G.V. April 24, 1951 [May 3, 1950] No. 9569/51. Class 38 (4). [Also in Group XL(c)] A frequency-selective resonant network has its selectivity and/or interference-rejecting properties 66, 68 increased by switching across its capacitance an energy-absorbing thermionic conductance 72, at intervals of approximate radio-frequency voltage zeros across it and with a period about one half that of the network (see Group XL (c) ). The switching frequency, e.g. 200 kc/s., is derived from a multivibrator 103 of frequency, e.g. 100 kc/s., and synchronized with the frequency, e.g. 100 kc/s., of the network 66, 68 to be controlled by a retroactive control system varying the bias across a cathode circuit 150, 152 of the multivibrator also forming the cathode circuit of a control valve 254. Negative going potentials are applied from the control grids of the multivibrator through series diodes 154, 156 to a common load resistance 148 and differentiated by a capacitor 160 to actuate a flip-flop 168 and produce a temporary transfer of conduction from valve 172 to valve 164 normally biased beyond cut-off, so that pulses of period, e.g. 2 Á sec. regulated in duration by a potentiometer 196 are generated of double the frequency of the multivibrator 108. The pulses are applied to a coupling valve 204 deriving from its anode and cathode circuits positive and negative pulses respectively applied to the shunt and compensating valves 72, 76 in shunt across the tuned I.F. network 66, 68. (The compensator and shunt valves 76, 72 alternately are cut off and conducting, and have the same anode current so that switching disturbances cancel out, but the shunt valve 72 is connected to have a lower resistance 1/Gm across the tuned circuit where Gm is the valve mutual conductance.) A reference I.F. wave is derived from a frequency changer 54 in parallel with the receiver frequency changer 58 feeding the tuned I.F. circuit 66, 68 and fed via a highly selective I.F. amplifier 260 and phase shifter 262 to a gating or coincidence valve 234 normally biased to cut-off, to another grid of which positive pulses from the coupling valve 204 are applied to coincide with the positive slope portions of the reference I.F. wave. Negative pulses are therefore derived from the anode circuit of the gating valve 234 and applied, through a capacitor 246 and shunt diode 248 acting as a smoothing circuit, as a positive control potential to the control grid of the valve 254, so that its cathode bias controls the phase of the multivibrator oscillations.

Title: Improvements in emulsified solid greases
IPC: C09K23/00
Filed: 1925-04-14
Abstract: Lubricants for machinery, e.g. the axles of trucks and tubs, consist of solid mineral oil emulsions made by mixing oil which has been treated by electric-glow discharges with about 50 per cent of water. Emulsifying-agents such as wool-fat, wool-fat alcohols, and montan wax may be used in conjunction with the polymerized oils.  The emulsion may be prepared by mixing atomized water with an atomized solution of the emulsifying agent in the mineral oil, or by injecting steam into a mixture of mineral oil and emulsifying agent, and mixing in the water.  In an example, 50 parts of water and 50 parts of electrically-treated oil having a viscosity of 30-40 DEG  at 100 DEG C. are used. Specification 209,060 is referred to.

Patent GB-1531520-A (GB)
Title: Method and apparatus for engraving screened printing surfaces
IPC: H04N1/40
Filed: 1976-03-11
Abstract: 1531520 Facsimile DR ING RUDOLF HELL GmbH 11 March 1976 [11 March 1975] 09879/76 Heading H4F Apparatus for engraving printing cylinders as described in Specification 7918/76 includes an engraving tool control circuit 48, Fig. 1, described in detail w.r.t. Fig. 5 (not shown), which causes the tool to engrave the first cell of each cell line, at half normal stroke. The cell is retrospectively engraved at full stroke on the subsequent revolution of printing cylinder 2. By this measure engraving errors are avoided which derive from overshoot of the engraving tool upon commencement of line engraving. Similar errors upon termination of line engraving are avoided by allowing the tool to perform a non-cutting half stroke into the second cell of the line after the retrospective engraving of the first cell prior to returning the tool to its inactive position. Figure 3 illustrates the state of first cell 109 immediately prior to retrospective engraving and (ghosted 110<SP>1</SP>) the deepest position through which the tool moves, prior to being deactivated, in the second cell 110. Figures 2 and 4 (not shown) are used to describe the input and output management of the digital processing unit 28, Fig. 1.

Title: Improvements in or relating to variable ratio transmissions
IPC: F16H63/18
Filed: 1960-03-21
Abstract: 943,634. Change-speed gearing; change speed and clutch control; positive clutches. ED. TERREIRINHA & IRMAO LDA. March 21, 1960 [March 20, 1959; March 8, 1960], No. 9927/60. Headings F2C, F2D and F2L. In a change speed gear providing two, as shown, or more ratios, wherein constant mesh gears a, b are rotatably mounted on, and selectively clutched to, a shaft A, and a clutch member 1 is slidably keyed on said shaft and is axially shifted to engage its external clutch teeth with internal clutch teeth of the gears, a pin 4, fixed on the clutch member and extending through a longitudinal slot in the shaft, is acted on by a spring 7 reacting on the shaft and, through a stronger spring 8, by a control plunger 5 actuated by a cam 6. The spring 7 is sufficient to bias the member 1, spring 8 and plunger 5 towards the cam. To permit cam rotation should the clutch teeth be out of circumferential register when engaging the gear a, the spring 8 is stressed until register is achieved. Drive is transmitted between shafts C and A through a shaft B. A gear c is clutched to the shaft C by a clutch member 14 which is acted on by a single spring 12 and, directly, by a control plunger 16 actuated by a cam 15. The cams 6, 15 are mounted on a shaft 11 manually rotated by a knob 17.

Filed: 1999-01-07
Abstract: PROBLEM TO BE SOLVED: To eliminate unnecessary pipe resistance and accurately detect a suction pressure when wafer suction and release are performed by providing an electromagnetic valve inside or on the upper surface of a wafer stage for carrying out wafer suction control. SOLUTION: An electromagnetic valve 4 communicating with wafer suction ports 3 and a pressure sensor 5 to detect a suction pressure for wafer suction are provided inside the wafer-stage 1. With this construction, the distance between the pressure sensor 5 for monitoring the wafer suction pressure on a chuck 2 and an actual suction part is reduced and the pipe resistance is also reduced. As a result, the pressure sensor 5 can detect the suction pressure accurately, and can recognize the wafer suction state on the chuck 2 accurately and quickly. Further, the piping distance between the electromagnetic valve 4 and the actual suction part is reduced and the pipe resistance is also reduced. As a result, a releasable pressure can be attained quickly when the wafer is released from the chuck 2, and the time required to release the wafer from the chuck 2 can be reduced.
