Title: Improvements in or relating to Mechanism for Feeding and Delivering Webs to Printing Presses.
IPC: B65H16/10
Filed: 1916-11-06
Abstract: 110,934. Goss Printing Press Co., (Goss Printing Press Co.). Nov. 6, 1916 Feeding webs.- The roll sbaft 6 is driven or retarded by an electromotor 14, and the shaft and the motor can be moved bodily in an axial direction for adjusting the roll with reference to the press or the like, or the motor can be moved independently to disconnect the shaft. Devices are provided for centring the roll. (1) As shown, the electromotor 14 can slide axially on guides 12, and the shaft 6 of the roll 7 can slide in its bear. ings 8 and is driven by a friction coupling comprising a friction member 18 which is feathered on the motor shaft and is pressed against a friction member 9 on the shaft 6 by springs 76 abutting on a disk 16 on the motor shaft. The motor is initially run in the same direction as the feed and is then reversed so as to act as a brake. The motor and the roll are moved bodily in an axial direction by the following device. The disk 16 and the member 9 are grooved to engage arms 29, 30 provided with threaded hubs engaging a threaded shaft 19 which can be rotated by a hand-wheel 26 or 27. The feed is arrested preparatory to substituting a new roll by depressing a hand-lever 45 arranged to move the motor independently and thus to separate the friction members 9, 18. The motor is provided with a rack 13 geared to a shaft 39 arranged in a sleeve 36 which is feathered to an arm 37 connected to a cross-bar 33 on the arms 29, 30. The handlever carries rods 46, 47 which can be depressed by levers 51, 52 to couple the hand-lever to the sleeve 36 and the shaft 39. In the initial part of the depression, the hand-lever is coupled to the sleeve 36, to disengage the arms 29, 30, and in the latter part is coupled to the shaft 39 to cause the motor to move. Further depression causes arms 78 to lift the shaft 6 out of the bearings 8, the arms being secured to a shaft 56 which is secured to the hub of the hand-lever. (2) Roll-centring gauges 66, 75 are secured to racks 63, 72 geared through shafts 60, 69 to the shaft 56. When it is required to insert a new roll, the hand-lever is depressed as described above to lift the arms 78. The shaft 6 of the old roll is then removed and the shaft of the new roll is rolled into the bearings 8, the arms being thereby depressed and causing the gauges 66, 75 to move against and centre the rolls. The movement of the gauges may be assisted by the handlever. The hand-lever is normally held in such a position that the gauges are out of contact with the roll.

Title: Improvements relating to the production of thermoplastic sheet material
Inventor: SAUL WALTER
IPC: B32B27/00
Filed: 1955-06-03
Abstract: Marbled thermoplastic sheets are made by passing through rotating rollers, at a temperature at which it is plastic, a laminated thermoplastic sheet comprising two sheets of substantially the same colour with an intermediate sheet of a different colour.  The laminate may have in addition one or more thermoplastic sheets of yet another colour or colours and may be, after rolling, applied to a backing of e.g. another thermoplastic sheet.  In an example, a buff coloured sheet 0,030 inch thick and a medium brown coloured sheet 0,030 inch thick were formed into a laminate 0,057 inch thick by passing through a two-bowl calender.  A buff coloured base sheet 0,400 inch thick was then placed on top of the medium brown surface of the laminate and a further dark brown coloured sheet 0,025 inch thick placed on top of this base sheet.  The assembly was then formed into a further laminate 0,400 inch thick by passing it through a two-bowl calender.  This second laminate was then passed through the lower nip of a three bowl calender, both nips of which were set at 0,040 inch the sheet emerging from this lower nip was folded back on itself to form a "bank" and fed into the upper nip of the calender. The finished sheet has a marbled surface with clear and sharply defined "veining".  In an alternative, the first two layer laminate is optional and the four layer second laminate may be built in a single stage.

Abstract: 1,187,901. Electron beam scanning. G. S. PLOWS, and W. C. NIXON. 28 March, 1969 [3 April, 1968], No. 15936/68. Heading H4F. [Also in Division H1] In using a scanning electron microscope to examine a specimen in which a phenomenon recurs periodically a stroboscopic effect is produced by pulsing or gating the beam at the recurrence frequency of the phenomenon. In Fig. 1 the specimen S is scanned to produce secondary electrons which are collected by a detector D, the output of which is fed to a display tube C scanned in synchronism with the microscope. A pulse generator E synchronized with the periodic phenomenon in the specimen operates a gate for the beam; this may comprise a grid but is preferably a diaphragm (T, Fig. 4, not shown) with a slit across which the beam is deflected at half the gating frequency. The system may be used to examine the dynamic voltage distribution in semi-conductor devices, and in one example the frequency of the phenomenon is 7 MHZ and the frame scanning frequency is 1 HZ.

Title: Improvements in or relating to boxes or receptacles for powder or other materials
IPC: B65D43/20
Filed: 1935-06-04
Abstract: 457,855. Boxes. BARLOW, R., 28, Kingsway, London, and COWAN, A. F., 48, Barnfield Avenue, Shirley, Surrey. June 4, 1935, No. 16093. [Class 18] A drawn or moulded box for powder or liquids has a sliding lid 3, Fig. 3, and a powder, &c. container in the form of an inverted tray 5 provided with an aperture 7 which, when the box is tilted, allows material to pass from the tray into a space 13 left between the tray and one end of the box. The tray is positioned in the box by means of an upstanding rib on the floor of the box, and the aperture 7 may be formed between the side wall of the tray and the bottom of the box. The side edges of the lid embrace beads 2 on the box sides, and when the lid is slid into the closed position, its forward edge rides up an inclined flange 10 which holds the lid tightly closed. The lid has a projection 12 to facilitate opening and closing, and its movements are limited by a rib 8 and a flange 9 both of which can abut against the end of the box. A pip 11 which can ride over the end wall of the box prevents accidental opening of the lid. In addition, to limit the opening and closing movements of the lid, the lid flanges may be provided with grooves engaged by ribs on the box sides as described in Specification 457,854. In this construction the tray is positioned against the ends of an inward bend on the top edges of the box walls. Tabs on the lid flanges may extend underneath the box and be engaged by pips on the bottom so as to limit the movement of the lid. To prevent accidental escape of powder, a zigzag strip of paper bearing advertising matter fills the space 13 and one end is passed through the aperture 7 or underneath the bottom edge of the tray. In a box for liquids, the aperture 7, Fig. 6, is closed by a spring-pressed plate 15 which is raised when the lid is slid back due to the engagement of a pip 17 with a tongue 16 on the plate. The box may also be of polygonal or circular shape. According to the Provisional Specification, the inverted tray can be replaced by a simple partition which may be of wire gauze.

Title: Vehicle separation measuring system
IPC: G08G1/16
Filed: 1973-04-05
Abstract: 1404069 Measuring vehicle separation PENTRON INDUSTRIES Inc 5 April 1973 [19 April 1972] 16302/73 Heading G4D A system for measuring the separation between two vehicles comprises pulse train producing encoders producing pulses for the same displacement in each vehicle and means for feeding the pulse trains to the up/down inputs respectively of a counter. Preferably the counter is in the second vehicle and the pulses from the first vehicle are transmitted by radio. Means are provided to set up the desired separation and to indicate whether the actual separation is less than, equal to or greater than that desired. As described pulses from the leading vehicle are transmitted by radio and passed along line 136 to shaping monostable 140. Trailing vehicle pulses are passed along line 138. Both sets of pulses trigger very short period monostables 158, 160 and these short pulses are passed to the up 152 (leading vehicle) or down 154 (trailing vehicle) inputs of BCD counter 144-150. The counter reading, which is the separation if the vehicles started from the same point is displayed on numeric display units. The desired separation is set up on switches 170-176 and is compared with the counter reading in comparators 182-188. The units stage 188 may be cut out by switch 178 for lower precision. Outputs are produced on line 180 when the vehicles are too far apart, 184 when the distance is correct and 186 when they are too near. These outputs switch resistors 196, 194, 192 into the feedback of oscillator 190 and cause output frequencies of 800, 500 and 300 Hz respectively which is fed to speaker 218 via burst generator 204. The desired output on line 184 also lights an indicator lamp. The burst generator switches the output frequency on and off at a rate proportional to the rate of change of separation (counter reading) when the separation is incorrect. A correct output on line 184 produces a "1" output at 212 which enables gate 214 and passes the 500 Hz signal continuously, When there is no signal on line 184 gate 214 is only enabled when there is a signal from the 4 output "B" of the units stage of the counter and this signal pulses at a rate proportional to the rate of change of the counter reading. The apparatus may also be set up at a point remote from both vehicles.
