Title: Improvements relating to the prepayment mechanisms of meters
IPC: G07F15/02
Filed: 1943-07-05
Abstract: 568,581. Prepayment mechanism for meters. BEGWACO, Ltd., and BUTTERWORTH, E. July 5, 1943, No. 10892. [Class 27] In prepayment mechanism of the kind having two coin slots and a twin coin-holder in which, for example, shillings and pennies can be inserted, a fixed quantity wheel f is disposed coaxially alongside a rotary quantity wheel a and a duplex planet pinion j is adapted to engage both quantity wheels simultaneously, the quantity wheels or the two toothed parts of the planet pinion having different numbers of teeth, one coin-holder turning the rotary quantity wheel directly and the other coin-holder p bringing the planet pinion j into operation and revolving it about the axis of the quantity wheels so as to impart the desired reduced amount of rotary motion to the quantity wheel a for the predetermined angular motion of the coin-holders. In the construction shown, the two quantity wheels f, a are equal, and the two parts of the planet pinion j have 12 and 11 teeth respectively. The pinion is journalled on a lever k pivoted at m and connected by a pin-and-slot arrangement with a slide n in the penny coin-holder p. Normally, the pinion is kept out of engagement with the quantity wheels by a spring o acting on the slide n, but when a penny q is inserted in the holder the slide is pushed up and the pinion engages the wheels. Rotation of the coin-holder by the handle r now imparts a rotation of one-twelfth the amount to the rotary quantity wheel a. When a shilling is inserted in the shilling slot, it enters a coinholder u (not shown) and pushes up a spring- loaded slide s<1> so that a tooth s on the slide engages the quantity wheel a and couples the handle r directly to the wheel a. Undesired movement of the wheel a is prevented by a brake comprising a spring i secured to the fixed wheel f and bearing against the face of the wheel a.

Title: An ergometer
IPC: A63B22/06
Filed: 1959-04-01
Abstract: 909,840. Exercising apparatus. JAEGER, E. April 1, 1959 [April 3, 1958], No. 11044/59. Class 132 (1). [Also in Group XIX] A crank device 7, transmission mechanism and an electric dynamo 8 form a structural unit 6 which is pivoted to a stationary support so that the crank device may be operated by a patient who is lying, sitting of standing up. As shown, the support 1 rests on adjustable feet 2, 3, 4 and may run on wheels 16 when lifted by handle 15. The patient may sit in a saddle clamped on unit 6 when the latter is in the full-line position, Fig. 1, resting on an arm 12 of housing 1, a detachable handle 10 being provided. For a standing patient, one pedal is replaced by a crank handle 18, feet 3 and 4 being elongated and turned out so that the patient can place his feet on them. For a prone patient, housing 1 is secured alongside a table 20 with adjustable head and shoulder supports 22 and adjustable arm and leg rests 26, 28. Unit 6 contains a chain wheel 32 driven by the pedals which, through a chain 34 drives a shaft 33 carrying a second chain wheel which through a further chain 35 drives a small chain wheel to drive the dynamo 8. The latter acts as a counterweight as the unit is moved about. As shown, Fig. 6, the armature 40 of a D.C. dynamo 8 connected in parallel with a load resistor 45 and a measuring instrument 44 calibrated in energy, the field winding 41 is connected in parallel with indicator lamp 56 and in series with a valve 42 and a D.C. source 43. The grid of valve 42 is connected directly to the anode of a control valve 47 and through a resistance 46 to its own cathode. The cathode of valve 47 is earthed through a gas discharge tube 48 and is connected through resistor 49 to the positive pole of source 43 connected in parallel with tube 48 is a variable resistor 50 and a potentiometer 51 whose connecting-point is connected through resistor 52 to the grid of valve 47. Initially, a relatively heavy current flows through valve 42 and winding 41. When the induced voltage created by the turning of armature 40, added to that tapped from potentiometer 51 reaches a specific value, diode 55 becomes conducting, the grid of valve 47 becomes more positive and the valve becomes conducting thus the anode of valve 47 and the grid of valve 42 becomes more negative and the current in winding 41 is reduced. In its turn, this reduces the voltage induced in armature 40 but this increases the current in winding 41 again so that the induced voltage tends to a constant value according to the setting of potentiometer 51 which is controlled by a knob 17. Lamp 56 is extinguished when a current flows through the diode 55. If lamp 56 is not visible to the patient a second lamp in parallel thereto may be provided.

Title: Improvements in or relating to control valves for geysers, water heaters or the like
IPC: F16K11/16
Filed: 1944-06-09
Abstract: 583,130. Multiple -- way valves. SANBRA, Ltd., and DINGLEY, P. N. June 9, 1944, No. 11123. [Class 135] A control valve device for geysers, water heaters and the like has two valve seat openings both communicating with the water supply mains and two valves for controlling these openings, the valves being operated by a single movable member such as a screwed spindle in such manner that during the operation of the movable member in one direction one valve 'seat opening is first opened and closed for the direct supply and shutting off of cold water, whilst continued movement of the movable member opens the other valve seat opening to give a maximum supply of water to the heater and then a supply at a gradually reduced rate. As shown, the device comprises a casing 1 with a partition 2 having valve seat openings 3, 4. The casing has a boss 8 connected to the supply mains and a boss 11 forming an outlet. Below the partition 2, the casing is divided into two chambers 9, 10 of which the latter has a passage 12 leading to the diaphragm chamber of the gas control valve and thence to the heater. The outlet from the heater and the outlet boss 11 are connected to a common discharge nozzle. The two valves 16, 17 are carried by a yoke 5 operated by the screwed spindle 7. Each valve carries a washer 15 to engage a seat below the partition 1. The valve 16' for supplying cold water directly has a reduced portion 16b and a collar 16a which obturates the opening 4 before a similar collar 17a on the valve 17 supplying the heater clears the opening 3. Subsequent movement of the valve 17 in the same direction brings a tapered portion 17b into the opening 3 which is thereby gradually closed.

Title: Improvements in or relating to movement-damping devices for gyroscopic instruments
IPC: G01C19/42
Filed: 1951-05-11
Abstract: 716,871. Gyroscopic apparatus. REID, G. H. Aug. 11, 1952 [May 11, 1951], No. 11223/51. Class 97(3) A gyroscopic apparatus includes a gyro-rotor in a pivoted gimbal frame, a spring operatively connected to the gimbal frame to restrain pivotal movements thereof and an eddy current device for damping oscillatory movement of the gimbal frame and spring, this device comprising a fixed element, and a movable element connected to the gimbal frame, one element being a magnet and the other being a body of electrical conducting material disposed in the field of the magnet. As applied to a rate of turn indicator, the gimbal 10 of which is urged towards its normal position by a spring 9 and is connected by gears 16, 17, to an indicating pointer 19, the eddy current device comprises a metallic rotor 43 carried by a spindle 40 connected to the gimbal by movement multiplying gearing 47-51 and a permanent magnet 32. The magnet is mounted on a spigot 31 in which the spindle 40 is freely rotatable. This spigot is carried by the end wall 30 of a cup-shaped member 21 having a flange 27 of magnetically-permeable material, engaged by a screw 28 passing through a helical slot in a member 22 secured to a fixed base plate 23. The induced magnetism resulting from the eddy currents formed in rotor 43 reacts with the field of magnet 32 to brake the rotor and thus damp out oscillations of the gimbal 10 so that pointer 19 gives a steady indication. The braking effort may be increased by rotating member 21 so that the magnet 32 is moved further into the rotor 43.

Abstract: 661,602. Centrifugal moulding of concrete pipes &c. FEJMERT, E. V. April 28, 1949, No. 11283/49. Class 87(ii) The rotations of the mould 3 feed tube 11, and feed screw 21 are controlled by cams on a shaft 10. In a modification the screw 21 may be replaced by a screw which moves the feed tube out of the mould to allow it to be refilled. A brake (not shown) may also be controllec by cams on the shaft. The mould is supported in a carrier 2, mounted at its ends in bearings and rotated by a motor 4 through V-belts. Rotation of the mould is controlled by a clutch 5 operated by a cam 9. Beams 18a (b), see also Fig. 2 (not shown), cause a driven shaft 15 to rotate the tube 11 through 180 degrees to allow material in the tube to be deposited through a slit therein in to the mould. The tube is then moved back through the same arc. A lever 26, fixed to the tube 11 and to rods 27a (b), which are fixed to the lower ends of rocker arms 17a (b), engaged by the cams 18a (b), ensures that the tube is brought to rest with the slit in the desired position. This position may be adjusted by a screw device connecting the rods 27a (b). The screw 21 may be reversed to feed excess material back to the hopper 20, A gear 22 controlled by a cam, see Fig. 2, on the shaft 10 drives the screw 21.

Filed: 1958-04-10
Abstract: 837,180. Rolling-machines. SCHLOEMANN A.G. April 10, 1958 [May 17, 1957], No. 11370/58. Class 87(2). [Also in Group XXII] In an apparatus for looping material that is being rolled and for storing  a  variable amount of rolled material between adjacent roll housings comprising a circular tubular guide open on the inside of the curve and having the lower part of the guide hinged to open downwards,  a  roller is arranged within the circular guide so as to prevent the formation of knots or kinks as the loop of rolled material contracts or is drawn in. Material 3 from vertical rolls 1, 2 runs through a guiding tube 4, a circular ,tube guide 5 and a guiding tube' 6 into the pass between horizontal rolls 8. The guide 5 is open on the inner side so that the loop can contract in a vertical plane and a section 9 of the guide, normally held closed by a spring 12 opens when the loop expands remaining open until reclosed at the end of a rolling operation. The size of the loop is regulated by photo-electric members 14 which vary the speed of the rolls 8. If the photo-electric members fail, with the loop contracting, a roller 15 arranged within the loop prevents knotting and when rotated by the loop actuates a switch 19 (not shown), which causes the train of rolls to stop. Alternatively in place of the roller 15 a bar may be used which actuates the switch 19 by a tilting movement.
