Title: Improvements in or relating to lifts, hoists and the like
IPC: B66B13/14
Filed: 1929-03-11
Abstract: 307,882. Associated Electrical Industries, Ltd., (Assignees of Kinnard, L. J.). March 15, 1928, [Convention date]. Lift cages and doors, locking and unlocking and operating. - Comprises a control system for ensuring the closure of the well doors and car gates at all times when the car may be moved, for automatically closing the car gate after a predetermined interval if it has not been closed by hand, and for automatically maintaining the car gate open when required. The car gate 1 is adapted to be normally closed by a spring 11 and linkage 7 connected to the gate and when closed completes a gate switch 29. An extension 15 from the linkage is adapted to be engaged by a clutch 17 controlled by a solenoid 18 to maintain the gate in the open position against the action of the spring. In operation, if the car C has opened the floor switch F<1> a relay 24 is de-energized. The gate is opened by hand breaking switch 29 and de-energizing a relay 28, the clutch 17 holding the gate open. The de-energization of relay 28 closes the circuit of a timed relay 25 fitted with a dashpot 26, thus giving time for the opening of the well door D<1> and breaking the door switch 19 and de-energizing the motor circuit relay 22. This prevents energization of the solenoid 18, through its contacts a, and completes a circuit for the holding relay 27, through its contacts b. The relay 27 completes a holding circuit for itself and partially completes a circuit for the solenoid 18. When the passenger leaves the car and closes the well door, the solenoid is energized to release the clutch and the car gate closes. If the passenger opens the car gate but does not open the well door at that floor, the gate is automatically closed, after the lapse of the time determined by the dashpot 26, by the release of the clutch 17. The gate can however be forcibly closed earlier by overcoming the frictional resistance of the clutch.

Title: Improvements relating to gramophone pick-ups
Inventor: WILLIAMSON DAVID THEODORE NELS
IPC: H04R9/16
Filed: 1954-03-18
Abstract: 774,121. Gramophone pick-ups. FERRANTI, Ltd. June 17, 1955 [March 18, 1954], No. 7981/54. Class 40 (4). A single V-shaped conductor 10 carrying a stylus 26 at its angular point is resiliently mounted for torsional movement between a permanent magnet 16 and the pole faces 24, 25 of a mild steel magnetic structure 20, the conductor having rigid channel-section arms 11, 12, the extremities 14, 15 of which are in resilient strip form and are fitted into slots 27, 28 in the magnetic structure to provide the torsional mounting. The conductor may be formed from cadmium-copper strip, from laminated metal and plastic such as nylon or from plastic material metallized on its surface. Movement of the conductor is damped by a rubber-like material which completely fills the air gap between boundaries 36. The direction of the magnetic fields associated with the two polepieces may be normal to the arms of the conductor for maximum output or merely inclined at an angle thereto. As mounted in a moulded plastic pick-up head, Fig. 3 (not shown), the end of the conductor remote from the pick-up arm is soldered at 31 to the magnetic structure which provides an electrical path to an output lead 33. The other conductor end is insulated from the magnetic structure and connected to output lead 35. The conductor, which is in strip form immediately adjacent the stylus, may alternatively be formed by two separate arms joined at the angular point. As nearby alternating fields may set up hum in the pick-up output by induction in the magnetic structure, a counteracting effect may be obtained by fitting a non-magnetic electrical conductor between the structure ends 17, 18, Fig. 4 (not shown). To completely balance-out the induced hum it may be necessary also to increase the electrical resistance of one path through the pick-up structure between 31 and 32 by introducing thin laminµ of non-conductive material which are bridged by electrical resistors. Alternatively the degree of induction in one path may be increased by introducing ferro-magnetic material of high permeability which is located so as to avoid interference with the primary field of the pick-up. Induced hum can otherwise be minimized by directly connecting lead 33 to the conductor extremity 14.

Title: Improvements in loud speakers, and like sound-reproducing devices
IPC: H04R7/12
Filed: 1926-03-24
Abstract: 271,207. Himmer, V. March 24, 1926. Diaphragms; l o u d - speakers. - A soundreproducing device for telephonic loud-speakers &c. comprises a diaphragm held by a flexible support which is itself rigidly sup. ported, the flexible support being secured to the diaphragm at a distance e from the periphery and having attached thereto a flexible binding which is also secured to the diaphragm and extends around it circumferentially. The loud-speaker shown in Fig. 1 comprises a conical diaphragm 13 of material such as paper, and a flexible frusto-conical support 12 of similar material, the member 12 being secured at its smaller rim to a rigid supporting ring 10 of wood &c. The outer rim is secured by adhesive 14, Fig. 4, to the diaphragm 13, the attachment being at some distance from the periphery of the diaphragm. A flexible binder 15 is secured over the meeting edges of the members 12, 13. The object of this is not only for strengthening, but also for causing unequal strains to be set up in different parts of the diaphragm on account of uneven shrinkage when the adhesive dries, so that as a result the efficiency of the diaphragm in reproducing sounds of widely differing frequencies is improved. The apex of the diaphragm is reinforced by strengthening layers 19, 20, 21, the layer 21 being larger and more flexible than the layers 19, 20, which are preferably of metal. Thus the rigidity of the portion near the apex of the diaphragm is graded, being greatest at the extremity. Fig. 5 shows a modification in which a spider 30 replaces the support 12 of Fig. 1. The electromagnetic unit 22 is supported within the ring 10, and its armature is adjustably connected to the apex of a dia. phragm by a rod 24 secured thereto by the parts 25 - - 28 shown in Fig. 3.

Title: Improvements in automatic electric battery-powered alarm clocks
IPC: G04C23/06
Filed: 1966-02-24
Abstract: 1,132,213. Alarm clocks. FABRIQUE d' HORLOGERIE LA VEDETTE S.A. Feb.24, 1966 [April 13, 1965: Sept.24, 1965], No.8088/66. Heading G3T. [Also in Division H1] An electric, battery powered alarm clock comprises a contact wheel 23 of electrically insulating material driven at a rate of one revolution in twenty four hours by the clockwork movement, the contact wheel carrying on one face an annular conductor 6 with which a fixed brush 11' makes permanent contact and on the other face conductors 7, 8 connected to the annular conductor. A lever 2, pivoted at 3 has arms 12, 13 so that as the wheel 23 rotates, the arm 12, at the preset alarm time comes into contact with a stop 4 mounted on a disc secured to an alarm hour setting spirelle 24. The lever 2, which is connected to earth, is thus rotated by the stop and sweeps over the conductors 7, 8 causing the alarm 1 to sound and then be repeated after an interval. A manual switch 14 may be operated to switch off the alarm or a switch 15 may be actuated which causes a delay in the sounding of the alarm. The switch 15 includes a peg which on actuation of the switch is entrained in the teeth of the wheel 23 and is only released to allow the switch to close after the wheel has rotated a predetermined amount. When the stop has been disengaged from the lever 2, a spring 35 urges the lever back to its original position. As shown, the alarm circuit is connected into the circuit for driving the clock which includes coils 19, 21 and a transistor 20. However, the alarm circuit may be independent of the clock drive circuit. The circuitry is formed on printed circuit boards and a switch (not shown) is included for connecting the alarm to the battery in order to test the state of the battery. The clock also includes a clockwork operated date indicating mechanism, Fig. 9 (not shown), and a device for manually changing the date indication.

Title: Improvements relating to heating and ventilating systems for motor vehicles
Inventor: ISSIGONIS ALEXANDER ARNOLD
IPC: B60H1/00
Filed: 1950-04-01
Abstract: 678,630. Heating vehicles. MORRIS MOTORS, Ltd. April 2, 1951 [April 1, 1950], No. 8222/50. Class 64(ii) Relates to heating and ventilating systems for motor vehicles in which a stream of fresh air that has been preheated by passage through the vehicle radiator 2 is additionally heated by an auxiliary heat-exchanger 6 (i.e. an air heater) before being discharged to the interior of the vehicle, the heat-exchanger 6 being arranged to receive a controlled supply of hot coolant from the engine cooling circuit. According to the invention provision is made for enabling a controlled stream of unheated fresh air to be delivered at will to the vehicle interior, individual valves 12, 13 which are linked with a coolant control valve 26 being provided for controlling the respective streams of preheated and unheated fresh air, and a single manual control device being employed to effect co-ordinated operation of all three valves. In the form shown, preheated air which has passed through the upper part of the radiator 2 is delivered through a duct 4 to the heat-exchanger 6, which is provided with a fan 8, unheated fresh air collected by a scoop 10 located adjacent the radiator 2 being passed through a duct 9 to the heat-exchanger casing and thence to the vehicle interior. Admission of preheated and unheated air to the heat-exchanger is controlled by the valves 12, 13, Fig. 2, which are located in the respective inlets 5, 11 and which are operated, together with the coolant control valve 26, by a lever 20, the arrangement being such that when the lever 20 is actuated the valve 12 controlling the supply of preheated air commences to open only after the valve 13 for the admittance of fresh air has been rotated past its fully open position, the coolant control valve 26 being operated simultaneously with the valve 12. In the position shown in Fig. 2, both air valves are closed and hot engine coolant entering the valve 26 through an inlet 27 is returned directly to the engine through a byepass pipe 29. Upon the requisite movement of the lever 20 the valve 13 is fully opened. Further movement of the lever 20 causes the valve 13 to assume the partly open position shown in Fig. 5 and at the same time the valve 12 is partly opened and also some of the hot coolant is directed by the valve 26 through a connection 28 leading to the heat-exchanger 6, thus additionally heating the air flowing therethrough via the conducts 4 and 9. Still further movement of the lever 20 causes the cold air inlet valve 13 to close and the pre-heated air inlet valve 12 to become fully open. At the same time the whole of the hot engine coolant is directed through the heat-exchanger 6 before being returned to the engine. Some of the air delivered by the fan 8 may be directed through pipes 31 to windscreen derminsters.

Title: Panty hose and method and apparatus for manufacturing panty hose
IPC: D05B23/00
Filed: 1969-02-14
Abstract: 1,217,433. Panty hose. GLOBOTEX A.G. 14 Feb., 1969 [14 Feb., 1968], No. 8304/69. Heading A3V. [Also in Division D1] A method of manufacturing panty hose comprises drawing a pair of separately knitted hip length stockings 10 over a pair of forms 38 arranged face to face, moving portions of the stockings to be sewn together towards and into contact with each other and sewing them together while still on the forms. The stockings are sewn along two substantially parallel seams 12, 14 which extend from an elastic double welt 24 at the waist to reinforced ladder-proof strips 18 separating the panty and stocking portions. The seams, alternatively, may converge and overlap in the crotch region. An apparatus for the continuous production of panty hose comprises two leg-shaped template forms 38 and four expander elements 56 arranged in pairs for horizontal movement towards and away from each other. The forms 38 have straddling brackets 40 over which the stockings are stretched and they may be moved to the right by a conveyer 30. The expander elements 56 are arranged in pairs on base plates 70 slidable on a guide bar 58, the base plates being horizontally adjustable by hydraulic or pneumatic piston and cylinder units 74 and the guide bar 58 being vertically adjustable by piston and cylinder units 60. A sewing station 50 which includes a sewing machine 52, vertically adjustable by a piston and cylinder unit 54, has an operating arm 62 carrying sewing needles 64 and an electrically heated wire 66, and a darning arm 68, the sewing machine being operated by an electric motor 71. In use, after the stockings have travelled along the conveyer 30 through dyeing, plasticizing and drying stations to the sewing station 50, the units 60 raise the expander elements 56 so that they are positioned within the stockings after which the elements 56 are moved together by the units 74 to bring the stockings together, the sewing machine 52 is raised by the units 54 so that the needles 64 contact the stockings at the appropriate place, the motor 71 is put into operation and the sewing machine is lowered under gravity while stitching the seams 12, 14, the surplus material between the seams being burned away by the electrically heated wire 66 as far as the welt 24. The surplus material may alternately be slit by a mechanical cutter. The stitching of the seams may alternatively be done while raising the sewing machine 52, the surplus material being removed during raising or lowering of the machine 52. The electrically heated wire or mechanical cutter may also be used for cutting the surplus threads after finishing the seams 12, 14. The straddling brackets 40 may be replaced by two parallel grooves in each form 38 into which the expander elements 56 are received. Hydraulically or pneumatically operated clamps may be provided to hold the stockings firmly on the forms when the expander bars are raised.
