Abstract: 952,158. Paper-making. WEST VIRGINIA PULP & PAPER CO. Dec. 14, 1962 [Dec. 14,1961], No. 47244/62. Heading D2A. To provide uniform flow across the width of a paper machine headbox 10 dilute paper stock is supplied through a tapered pipe 18 to a plurality of rows of identical parallel pipes 19 which discharge into a headbox inlet chamber 20 in which a perforated flow mixing roll 21 is mounted in spaced relation from the outlet ends of the pipes 19. The pipes are designed to provide relatively high velocity streams under fully turbulent flow conditions at relatively high pressure drop through the pipes. The high pressure drop serves to equalise the velocities in the pipes and to prevent pressure surges upstream of the pipes from adversely affecting the flow in the headbox. The turbulent flow conditions provide a deflocculating action on the paper stock. Relatively high velocity jets of paper stock emerge from the outlets of the pipes 19 and impinge upon the roll 21 being blended thereby into a single uniform stream of paper stock that flows into the headbox. The inlet chamber 20 is attached to the headbox in angled relationship with the upstream end wall 16 and with the bottom wall and is of uniform rectangular section of width equal to the width of the headbox. The pipes 19 are attached to the end wall 24 of the inlet chamber in a uniformly spaced pattern (Fig. 3 not shown). The bearings for the roll 21 are mounted so as to provide adjustment of the distance between the roll and the outlet ends of the pipes 19 (Fig. 4 not shown) this adjustment being desirable to accommodate varying paper stock flows.

Abstract: 1,167,863. Applying labels. ASSOCIATED AUTOMATION Ltd. 11 Nov., 1966 [12 Nov., 1965], No. 48110/65. Heading B8F. A carriage 12 pivoted at 13 on a swinging arm 3 carries into engagement with a package a label fed along the arm, and is angularly displaced by engagement with the package to apply the label. In the form illustrated labels are carried by a backing tape which is bent round a sharp edge 7 so that the label is detached and supported between a roller 9 and a blade 10 with its end projecting under an applying roller 8. The pivoted carriage engages the package through a roller 11. The articles are carried by a conveyer (not shown) either past a photo-cell, or under a sensing roller (50), (Fig. 5, not shown), which releases a latch to permit the arm 3 to fall from its normally horizontal position and apply a label. After a pre-determined delay the arm 3 is raised by a rotary solenoid (15) so that a label on a printing platen 14 on the arm 3 engages an inked tape 18 passing over a printing roller. The labelcarrying strip is then fed by a roller mechanism 26, 27 driven through a one-way clutch from a further rotary solenoid, until a feeler 35 detects the edge of a further label. The feeler 35 is pushed against springs 45, 47 before it operates a switch stopping the feed, so that whether the arm 3 subsequently again falls the feeler 35 is pulled against the direction of label feed to ensure that it clears the detected label. A separating member 44 prevents the label sticking to the feeler 35. The feeler 35 and its associated mechanism can be moved to cater for labels of different lengths.

An I.C. engine 1 has a main cooling circuit comprising a radiator 2, thermostat 5 and pump 6, which is designed for a cooling power below that necessary at maximum load, and an auxiliary cooling circuit including a reservoir 7, radiator 10 and pump 11 which is brought wholly or partly into communication with the main circuit by a valve 12 when required by the thermostat 5. As illustrated, a supercharger air cooler 21 is included in the auxiliary circuit, and when the valve 12 is operated to connect the two circuits, a valve 23 is automatically operated so that only the reservoir 7 is connected in the main circuit and so that the pump 11 passes liquid round the circuit formed by the radiator 10, pump 21 and pipes 24 and 8. A thermostat 22 may be provided to override the valve 23 so that below a given temperature the valve will partially re-establish the connection between the reservoir 7 and the radiator 10. A pressure relief valve 18 is provided on the reservoir 7. The reservoir may contain a wax which melts at a temperature below the coolant evaporation temperature to extract heat from the coolant, and which solidifies at a temperature which is above the lowest temperature of the reservoir liquid. Small bore pipes 15, 16 and 17 connect the engine cooling jacket, the reservoir 7 and the two radiators. The two radiators together may be insufficient to provide full load cooling, the mass of liquid in the reservoir being relied on to provide the balance. In another embodiment, Fig. 1 (not shown), there is no supercharger and the valve 23 is omitted so that the only function of the auxiliary circuit is to aid the main circuit in cooling the engine.

In a film transport mechanism for a teaching machine, including a drum 5 open at one end and coupled to a film-engaging sprocket (not shown), momentary energization of a solenoid 13 moves a link 11 to bring a friction wheel 10, supported by a swing-link 7 and driven by a reversible motor (not shown) via a belt and pulley 14, into driving contact with one surface of the drum to rotate the latter, a pinch wheel 15 on the link 11 engaging the other drum surface to maintain said driving contact until the pinch wheel drops into an axial slot 6 in the drum to allow friction wheel 10 to cease contacting the drum. The spacing of slots 6 is chosen so that each driving step moves the film one frame. The drive direction may be controlled by a photo-electric circuit reading from the film. The solenoid 13 may be controlled by a telephone dial which feeds pulses to the solenoid, the step time of the mechanism being less than the time between pulses. For continuous drive for rewinding, solenoid 13 is energized continuously. In a modification, the friction wheel and pinch wheel are supported by parallel links, the solenoid acting on a vertical link pivoted to the parallel links intermediate their ends. A spring acting on the upper link urges the friction wheel towards its disengaged position.
