Title: Improvements relating to photographic reflex cameras
IPC: G03B7/06
Filed: 1947-04-09
Abstract: 633,140. Photographic reflex cameras with exposure meters. SOC. CIVILE MOROY. April 9, 1947, Nos. 9414 and 9415. Convention dates, April 19, 1946, and March 7, 1947. [Classes 97 (i) and 98 (i)] [Also in Group XL (b)] A photographic reflex camera of the kind having a photo-electric cell on the mirror so that when the measurement of the time of exposure is made the cell is located in the direct path of the light rays issuing from the objective lens, and a micro-ammeter measuring the current generated by the cell, has an indicator movable along the path of the microammeter needle by means which also displace the shutter speed control, so that alignment of the indicator with the needle sets the shutter speed required for the amount of light falling on the cell. As shown, Fig. 4, the objective 1 is mounted on a rising and falling front. The mirror 3 is slidable on an insulating support 4 pivoted horizontally at 6, and spring-urged so that its front edge slides on the camera wall during part of its travel. It has a thin coating 3a of photo-electric material, e.g. caesium, connected by leads 8, 9 to a microammeter 10 on top of the camera. Light admitted by the objective falls on the layer 3a to generate a current, and is reflected to form an image on a ground glass screen 14 covered by a removable or collapsable hood 15 with an eye. piece 16. A pointer 30, Fig. 2, has an internally toothed sector 20 engaging a pinion 21 rotatable by a disc 23. Pinion 21 is geared to the shutter speed control so that when pointer 30 is aligned with the needle 17 of the micro-ammeter 10, the shutter speed is adjusted. for the correct exposure. Pointer 30 is pivoted at 19 to a plate 31 slidable to disengage pinion 21 from sector 20 for adjustment for emulsion speed by means of a pointer 32 and a scale on disc 33. Ths shutter is of known kind, e.g. a sliding-plate shutter wherein the interval between the release of the plates is determined by an airbrake adjusted by a cam. In a modification, an aluminium surface layer of the mirror transmits about 25 per cent of the incident light to a pure iron plate coated with selenium beneath the mirror. The iron plate and a peripheral copper strip in contact with the selenium are connected to the micro-ammeter on the side wall, the needle of which moves in a vertical plane, and has a bent-over end moving above the viewing screen. A similar needle on the other side of the camera is brought into alignment with the first by a knob geared to the shutter speed control. The needles and a co-operating scale on the top of the camera are self-luminous. A variable resistance housed in the control knob may be connected in series with the meter and cell and adjusted according to the speed of the emulsion by a scale with separate indications for daylight and artificial light.

Title: Method and apparatus for determining, indicating and recording the irregularity of a flow of textile or like material
IPC: B65H63/06
Filed: 1957-03-25
Abstract: 850,180. Deluting and recording yarn &c. irregularities. BUTTICAZ A., TESAGE, C., and DEMBOWSKI, H. March 25, 1957 [May 3, 1956], No. 9749/57. Class 120(3). [Also in Group XXXVI.]  The irregularity of a flow of textile material is determined by passing it between the plates of a condenser the capacity of which is compared with that of a reference condenser, the difference signal being compared with a reference signal. General principles (Fig. 1). A ribbon or thread of textile under test passes between a central plate 12 and an outer plate 13 of a condenser while a further plate 14 constitutes, with plate 12, the reference condenser. Plates 12, 13, 14 are all surrounded by guard plates. The output of an oscillator 18 is applied through the outer terminals of the centre-tapped secondary of transformer 17 to plates 13, 14. The centre plate is coupled by condenser 20 to the input of a tuned amplifier 22. The output of the amplifier is fed to a pair of detectors 23, 24. Detector 23 supplies automatic gain control for the amplifier to vary the datum of the signal at a rate determined by the time constant of an integrating circuit in the feed-back arrangement, while detector 24 feeds a signal to a differential amplifier 28 where it is compared with a continuous reference supplied by source 29. The difference signal operates a centre zero indicator to indicate the direction of deviation of thread thickness from the mean, a rectifier integrator 31 feeding meter 32 to enable the mean error signal to be determined, and an amplitude counter 33 which lights the appropriate one of lamps 34, 35 when the signal goes above, and below a predetermined value. A compound condenser construction is described with reference to Figs. 4-8, (not shown) which enables a differential condenser of size appropriate to the thread or material under test to be selected.

[Class 79 (i)] A girdle track attachment for pneumatic tyres comprises a series of U-shaped shoe or tread members attached by their side links to a pair of flexible stranded wire ropes disposed exteriorly of the shoe or tread members, each shoe being provided with rope-engaging outrigger 'brackets adapted for engagement with the ropes at points intermediate the shoe or tread members, whereby premature failure of the wire ropes due to flexing at the point of attachment to the shoe is prevented. The wire ropes may be continuous or a number of short lengths may be used, extending only between adjacent shoes, whereby in the event of damage, one section only need be replaced. The track comprises a series of U-shaped members 10 having plates 14 on either side thereof to which the cable 11 is clamped between plate 17, projection 20 and part 18 which is spirally fluted internally to mate with the cable 11. The plates 14 have extensions 15 in both directions, terminating in pads 16 for engaging the cable 11 intermediate the shoes, so that when the shoes 10 engage the tyres 12, 13 excessive flexing of the cables at the clamps is avoided. The ends of the cable are held in special shoe members 10a having two clamps. Alternatively, every shoe member may be of the type shown in 10a and short lengths of cable utilised.

Title: Filter element
IPC: B01D25/24
Filed: 1952-04-18
Abstract: 703,823. Filters. BAUER, J. V., and CURTIS, R. H. April 18, 1952, No. 9835/52. Class, 46. [Also in Group XXVIII] An element consists of a corrugated web and a flat web of filtering material, convolutely wound together, the adjacent flutes formed by the corrugations each having one end open and the other end closed, these ends alternating ; closure is effected at one end of the element by adhesive and at the other end by collapsing and sewing of the appropriate flutes. The webs may be initially secured together as shown in Fig. 1 where the attachment is at the troughs of the corrugations. The flutes 4 formed between the webs 2 and 3 of the strip 1 are closed at the edge 5 by flattening the corrugations and sewing the webs together. The element may be made by mounting a cylindrical core 13, Fig. 3, on a mandrel 14, attaching a leader 16 of the strip 15 to it, and winding under pressure of a roller 20. The flutes 10 facing upwards are closed at the edge opposite to the sewn edge 7 by a self-hardening cement 17 extruded from a nozzle 18. As an alternative to sewing the edge 7, adhesive may be omitted from between the webs at this edge during manufacture of the composite strip and cement extruded into this region during the winding of the element, as shown in Fig. 4. The upwardly-facing flutes are closed by extruded cement as before. In each case a leader strip 20 or 36 respectively is provided for wrapping round the completed element. A cap 59, Fig. 7, is applied to the upper end of the core 40 and a frustro-conical disc 58 to the outside of the element at its lower end, these members having holes by which they may be accommodated on the perforate discharge pipe 46 of a complete filter 45. One or more holes 42 in the core 40 provide access for filtered oil to the region surrounding the discharge pipe 46. The complete unit is pressed between washers 56 and 57 by a spring 60 engaged between the washer 56 and a cap 47.

Filed: 1969-02-24
Abstract: 1,233,966. Machines with permanent magnets. KELSEY-HAYES CO. 24 Feb., 1969 [1 July, 1968], No. 9863/69. Heading H2A. A tachometer for sensing the speed of a first member which is rotatable relative to a second member comprises a rotor connectible to the first member and a stator connectible to the second member, the stator being mounted for radial movement in a given direction in response to movement of the rotor in that direction, the rotor movement being caused by movement of the first member relative to the second in the same direction. The tachometer shown is mounted on a vehicle axle assembly and comprises a rotor 70 mounted on a shaft 14 and a stator 50 mounted by means of resilient clips 34 on a plate 26 secured to a bearing housing 20. Radial movement of the rotor 70 (caused by radial deflection of the shaft) results in a smooth cylindrical part 76, Fig. 2, of the rotor engaging a smooth surface 68 on the stator, thus moving the stator against the action of the spring clips so as to maintain a predetermined minimum distance between teeth 54 and 74 on the stator and rotor respectively. A lug 44, on a non-magnetic stator housing 30, engaging a slot 46 in the plate 26 permits radial but prevents angular movement of the stator. The tachometer is of the inductor type with a permanent magnet and an output coil 56 both on the stator. In a modification (not shown), the part 76 of the rotor bears directly on the surface 68 of the stator, even during normal running.

Date Jun. 16, 1988.A duplex data transmission system in which a station can vary its transmission power to keep the signal-to-noise ratio the same in each direction or, in a system employing a different data rate in each direction, to keep the two ratios in a fixed relation to one another. In an initial training sequence, each station measures "talker echo" from its own transmission, and subsequently measures noise from the other station's transmission. The other station then makes the same measurements. The noise data thus collected is sent by both to a control circuit in one or other station which calculates from both sets of data an adjustment (e.g. a reduction) of the power to be transmitted. One or other stations then accordingly reduces power.
