Title: Improvements in or relating to proportional measuring apparatus
Inventor: MCWILLIAM DONALD ALISTAIR
IPC: G01G19/34
Filed: 1969-05-08
Abstract: 1280225 Measuring flow rate; electric calculating AUTOMATIC CONTROL ENG Ltd 7 May 1970 [8 May 1969] 23598/69 Headings G4A and G4H An apparatus for measuring the flow rate of a solid or fluent material, generates pulses for each given batch of the material, and interpolates between the pulses by means of a fast oscillator clock. Pulses corresponding to discrete quantities of material are generated by the weigher 10 and fed on line 11 to counter 15. A fast oscillator clock 16 feeds pulse trains to registers 17 ... 20, which are controlled by means of a timer 13 and the pulses from the weigher 11. Register 17 starts when a pulse 50 from weigher 10 appears on line 11, and is stopped by a start pulse from timer 13, so that it measures quantity A, Fig. 3. Register 18 is started by the start signal from timer 13, and is stopped by the passage of a pulse from weigher 10 so that it measures quantity B. Register 19 is started by a pulse from weigher 10, and stopped by a stop pulse from timer 13 so that it measures quantity C. Register 20 is started by the stop from timer 13 and stopped by a pulse from weigher 10, so that it measures the quantity D. In an arithmetic unit, units 22 and 23 form the quantities B/(A+B); C/(C+B). These quantities are then added together with the output from counter 15 in a summing unit 24 and used to display the flow rate. By using an integral number of pulses from a second flow measuring apparatus, to determine the time interval defined by timer 13, two flow rates may be compared. The apparatus may be used for measuring relative flow rates of products in a flour mill.

Title: Improvements in or relating to optical scanning systems
Inventor: BEACH ALLAN DAVID
IPC: G01J5/08
Filed: 1969-02-28
Abstract: 1298457 Optical scanning systems NATIONAL RESEARCH DEVELOPMENT CORP 26 Feb 1970 [28 Feb 1969 8 May 1969] 11007/69 23624/69 Heading G2J [Also in Division H4] An optical scanner comprises a drum 1 of imaging elements 3 such as lenses or mirrors, a faceted mirror 4 which is small relative to the drum diameter and fixed relative to the drum, each facet facing a respective element 3 and being inclined to the drum axis so that the reflection of the optical axis of the element 3 in the facet extends parallel to the drum axis, and a motor 2 for rotating the drum 1 and mirror 4 together so that each such reflection of the optical axes of the elements 3 in turn coincides with a given axis. As shown, infra red radiation from an image 8 is passed by a plane mirror periscope 9, 10 to a mirror element 3<SP>1</SP>, which may be spherical but is preferably of conic section, and is thereby focused at or near the surface of the corresponding mirror facets and passed via relay mirrors 5, 6 to a detector 7. Such a system is said to minimize vignetting by the facet edges. Rotation of the drum and mirror 4 thus scans a line 12 of points 13 and vertical scanning is performed by deflecting the mirror 10 by a cam driven by the motor 2. If the elements 3 are lenses, mirrors 9 and 10 may be omitted, and the mirrors 5, 6 may also be replaced by a lens system. In the embodiment shown, the mirror 4 is coaxial with the drum and the "given axis" is therefore displaced from the drum axis. In Fig.5 (not shown), the mirror 4 is mounted eccentrically of the drum and geared thereto, so that the "given axis" and the drum axis are coincident, which is preferred. Also the drum is mounted horizontally and mirror 9 omitted. Each element 3 and the cam driving the mirror 10 are provided with reflective facets which co-operate with respective light sources and photo-diodes to provide line and frame sync. pulses respectively. Alternatively a peg or flag on each mirror 3 may interrupt a light beam. To provide upper and lower reference levels e.g. in infrared thermography:- (a) a solenoid may insert a fixed temperature source between the drum and the mirror 4 once per frame (b) the facets of mirror 4 may be separated by slots through which a reference source is visible once per line (c) black vanes may be disposed between the facets of mirror 4 to emit at the ambient temperature, or (d) reflective vanes between the mirror facets and at an angle thereto may reflect light from a fixed reference source to the detector 7, Fig.2 (not shown). The signal from the detector 7 may be converted to a digital signal supplied to circuits generating characters from the digital values which are displayed in the relevant position on a television screen. Such circuitry may be operable only for a selected area of the image 8. A rangefinder producing two visible light beams resting in the plane 8 may be provided. The detector may be replaced by a light source for display purposes.

Title: Improvements in and relating to discharging tins from the trays of oven or other bakery unit conveyors
Inventor: WARRINGTON JAMES IRVINE DUDLEY
IPC: A21B3/07
Filed: 1949-09-22
Abstract: 696,122. Bakers' ovens. BAKER PERKINS, Ltd. Dec. 20, 1950 [Sept. 22, 1949], No. 24345/49. Class 51(ii) [Also in Group XXX] In apparatus for discharging baking tins or loaves from swing trays or controlled level trays having slot and finger comb-like constructions of the type employed on the travelling conveyers of bakery oven and prover units according to Specification 696,123, discharge of the tins takes place on an ascending lap of the tray conveyer 3 by means of a discharge conveyer comprising chains 5 carrying twin bearing platforms 12 with deeply slotted forward edges forming prongs 12a intermeshing with the prongs of the oven trays 1 as each said platform moves up below and behind and at a faster rate than an oven tray passing the discharge station, thereby removing the baking tins. As the discharge conveyer passes along its lower horizontal run, a plate 20 pushes the tins off the bevelled rear edges 24 of the platforms on to the cushion 23 of a guide rail 22 which deposits them on an endless belt 21. Swinging of the platforms 12 is prevented by connecting their chain pins 11 through crank plates 14 and 15 and a crank pin 16 to control chains 4 having vertical laps offset from those of the chains 5. In a modification, Fig. 5, the discharge apparatus comprises a platform 53 formed with upstanding partitions 55 engaging the slots in the oven conveyer trays and mounted on a carriage 51 having rollers 52 positioned on rails 50, the platform being also formed with guide posts 57 slidable in bearings 58 in the carriage and terminating in rollers 59 which engage return tracks 60 as indicated below. As each oven conveyer tray 1 moves up to the discharge station, telescopic arms 61 rocked by a crank 65 move the carriage 51 below the oven tray and above an elevating table 70 which is actuated by cams 75 to raise the platform through the oven tray removing the baking tins, the platform being immediately moved rearwardly along the return tracks 60 until the rollers 59 reach the end of said tracks 60 when they drop, together with the platform, into their initial position. In this position, a bar 77 carried between arms 78 secured to a shaft 79 operated by a bell crank lever 80 drops down behind the tins and on the next forward movement of the carriage 51 said bar 77 pushes the tins down a co-acting carriage ramp 67 and fixed ramp 82 on to a conveyer or table 69, the bar being then raised. With both embodiments, a charging station is positioned above the discharge station on the same upwardly travelling lap of the tray conveyer.
