Title: Improvements in or relating to continuous presses
IPC: B31F1/00
Filed: 1963-08-22
Abstract: 1,055,564. Laminates and laminating; woodworking. HOOVER BALL & BEARING CO. Aug. 22, 1963 [Aug. 22, 1962], No. 33368/63. Headings B5L and B5N. A continuous press incorporating heating arrangements and used for forming, e.g. laminated plastic surface boards and casehardened wooden boards of various widths, comprises means for moving a workpiece through an area wherein the workpiece is subjected to heat and pressure, a first heating element being disposed transversely across the full width of the pressure applying means, and a second heating element adapted to heat only those areas within the lateral confines of the workpiece. In an embodiment, thin endless sheet metal belts 30, Fig. 1, move a workpiece 18 between shoes 14, 16 mounted on frame members 12, the gap between the shoes being variable by virtue of spacers 42-48. Each shoe has an extension 20 followed successively by a preheated section 22, pressure step 24, curing section 26 and cooling section 28, and is of the same width as the belts. Where the workpiece is of less width than the belts, a heating system as shown in Fig. 2 is employed for the shoes in both the preheat and curing sections. As shown, a heating unit 50 comprises a main heater 52 which extends over the full width of the belt, and to which is connected a temperature controller 54 incorporating a thermocouple 55 situated in the shoe near the edge of the belt. Also included in the heating unit is a series of zone heaters 56 connected in parallel and controlled by the differential temperature controller 58 and thermocouple 60 situated in the shoe near the centre of the belt. When the workpiece is of less width than the belt, those zone heaters outside the lateral confines of the workpiece are disconnected by switches. In operation, the zone heaters are controlled to maintain a temperature slightly less than that maintained by the controller 54.

Title: Improvements in multiple unit electric motor control systems
IPC: B60L15/00
Filed: 1935-12-04
Abstract: 466,285. Master control of motors. GENERAL ELECTRIC CO., Ltd., and CROFT, E. H. Dec. 4, 1935, No. 33631. [Class 38 (iii)] In a multiple-unit control system in which line switches, giving overload protection and control of the motor circuits under the control of a master controller, have interlock contacts upon which the operation of the motor control gear is dependent, auxiliary testing interlocking means are provided which when effective, enable operation of the control gear to be tested while the line switches are open, and are so arranged that closure of the line switches is prevented while a test is being carried out. The invention is described in connection with a control system in which motors are accelerated by armature resistance control, with series and parallel connections of the motors, and field weakening, the acceleration being governed by a current limit relay. A test relay, having an operating coil 60 and contacts 61 which simulate the operation of the interlocks of the line switches, is energized by operating a pressbutton switch 68 which trips overload relays 65 thereby closing auxiliary contacts 66 in circuit with the coil 60. The opening of the contacts 64 of the overload relays ensures the de-energization of the operating windings 62, 63 of the line switches. Auxiliary contacts may be provided on the switch 68 and included in the test relay circuit so that the relay operates only on operation of the switch 68. In a modification the test relay is moved to a latched position by the energization of one winding and released by energization of another winding, and is provided with auxiliary contacts which open the circuit of the energizing coils of the line switches when the relay is in the testing position. Resetting coils for the overload relays are energized when that relay coil is energized which operates the relay to its normal position. In a further modification, the test relay is moved from a normal position, to which it is biassed, by the energization of an operating coil, and when operated the relay opens auxiliary contacts in circuit with the operating coils of the line switches. In a further modification, when overload relays are tripped they close contacts in an energizing circuit for the test relay, and the latter is operated under the control of the master controller so that the motor control gear may be operated in the reverse and the forward direction.

Title: Lung ventilator
IPC: A61M16/00
Filed: 1975-08-13
Abstract: 1506606 Lung venilators FORREST MORTON BIRD 13 Aug 1975 [22 Aug 1974] 33721/75 Heading A5T [Also in Division F2] A lung ventilator is provided with means for establishing an adjustable additional flow of gas to the patient after the major portion of the inspiratory phase has been completed. In the ventilator, gas is supplied from a source to the inlet 67, Fig. 17, of a servo controller 87 which is open during the inhalation phase to allow gas to pass to outlet 71 of the controller and thence to a patient adapter 307, Fig. 1, through a flow rate control valve 189, Fig. 17, and Venturi assembly 229; gas from outlet 71 also passes by a line 287 to a chamber 178 of a diaphragm-operated valve 51 to bias the valve open whereby gas from the source passes through the valve to an inspiratory power fitting 219 to bias an exhalation valve 308, Fig. 1, closed and also to the patient adapter, gas further being supplied to the exhalation valve and the adapter from the servo controller via lines 187, 194, 197, Fig. 17. The pressure in the patient's lungs is transmitted through a line 262 to a chamber (102) Fig. 7, (not shown), of the controller to act on a diaphragm (94) of the valve thereof. When a predetermined pressure is reached in chamber (102) sufficient to overcome a magnetic force biassing the valve open, the valve closes. However, chamber 178 is still pressurised and the valve 51 remains open until said chamber has bled down sufficiently through lines 287, 238. Gas therefore still passes to the fitting 219 through valve 51 during this period of closing to keep the exhalation valve closed, the bleed-down gases passing through Venturi assembly 229, where they entrain atmospheric gases through a filter 245, and to the patient adapter. On closure of valve 51, the exhalation valve opens, the expiratory period lasting until the pressure in chamber (102) reaches a predetermined reduced pressure sufficient to overcome a magnetic force biassing valve 87 closed, whereafter the inspiratory phase again starts. The source gases pass through a nylon mesh filter 43 before reaching controller 48 and valve 51. A flow rate control valve 282 is provided to control the flow rate from the controller to the Venturi assembly and also to control the rate of bleeding down of chamber 178 after closure of the controller valve to the Venturi assembly. A pressure gauge 163 connected to line 262 indicates the pressure in the patient's lungs. A nebuliser 304, Fig. 1, is connected to the patient adapter, gas from the Venturi assembly and fitting 219, Fig. 17, passing therethrough before reaching the adapter. An excess pressure relief valve 268 is provided in the Venturi assembly. The air exhaled through valve 308 Fig. 1, passes through a vapour trap 312 containing a flapper valve (337) Fig. 16, (not shown), which normally closes openings (336) in a plate (333). The flapper valve forces the patient to exhale against a positive pressure.

Title: Improvements relating to ink ribbon feeding mechanism in typewriting machines
Inventor: TONKS GEORGE HARRY
IPC: B41J35/06
Filed: 1960-10-01
Abstract: 961,839. Ink-ribbon mechanisms. GRAPHIC TECHNOLOGY Ltd. Dec. 15, 1961 [Oct. 1, 1960; Dec. 17, 1960], Nos 33753/60 and 43508/60. Heading B6F. An ink-ribbon mechanism, Fig. 1, which may be detachably mounted on an existing typewriter, comprises a pair of ribbon spools 14, 15, each mounted on its own separate shaft 16, and 19, respectively, a ribbon or ribbons 13 fed past a guide 26, one associated with each ribbon spool for guiding of the ribbon or ribbons in a path parallel to the axis of a platen 12 and an electrical motor 27 for driving one or the other of the shafts 16, 19, depending upon which one of the spools is acting as a take-up spool. Automatic reversing of the spool drive is effected when a clip 45, Fig. 5, attached to the ribbon of a currently acting supply spool comes into contact with a roller 43 and a pin 44, mounted on an arm 40, to pivot the arm 40 about a shaft 41 so that a cam 49 on the arm depresses a button 48 of a micro-switch 47, whereby the direction of rotation of the motor 27 is reversed. The angular movement of the arm 40 causes also a cam 42, mounted on the other end of the shaft 41, to pivot an arm 46 in an anti-clockwise direction so that on the subsequent exhaustion of the ribbon on the other spool the clip 45, upon engaging the roller 43 and pin 44 on the arm 46, will pivot the same and displace the arm 40 angularly to release the button 48 and reverse the direction of rotation of the motor once more. Associated with the rotation of the motor is also a pivotal movement of a plate 32, mounted on a pin 33, Fig. 2, and carrying change-over gears 37, 39 associated with driven gears 36, 38 (Fig. 4, not shown), respectively, for selective driving of shafts 19 and 16, through pivotal engagement with their corresponding gears 21, 20 brought about by the change of rotation of a driving pinion 30. A braking effect applied to the supply spool so as to maintain the ribbon or ribbons under constant tension, is ensured by the provision of co-operating friction surfaces 22, Fig. 1, on the closely spaced, counter-rotating gears 20, 21, the gears being spring-urged into contact. A guide arrangement, in Fig. 7, in another embodiment facilitating the lifting of the ribbons clear of the documents, for the purpose of their insertion, comprises a pair of shaped guides, including parts 54, 55, 56, 57, which are vertically slidable in two channels 53, 58, the guides engaging with notches 63, 64, a projecting head 62 on a detent 61, in their respective operating and idling positions, a tension member 65 having two arms 66, 67 with the former pressing against a shaft 68, taking up the slack in the ribbon by pressing a pin 69 outwardly against the back of the ribbon during the vertical movement of the guides.
