Title: Device for delivering a powder material
IPC: G01G13/00
Filed: 1970-11-02
Abstract: 1332806 Weighing apparatus H IWAKO 2 Nov 1970 [7 Nov 1969] 52023/70 Heading G1W An automatic weighing machine for particulate material comprises a balance B1 having first and second balance arms the first of which carries a dispensing device A which is driven to dispense the material by a driving means E at a given rate. Feeding means C is operated periodically to discharge the material into the device A. A control circuit arrangement is provided for operating the machine and initially causes a chain weight 22 to apply a load to the second balance arm to a predetermined amount and the feeding means C charges the dispensing device until the arms balance and then discontinues feeding. The chain weight is then withdrawn so that it has no effect and the driving means E operates to cause the device A to dispense the material. The control circuit includes a setting counter and a timing counter the pulses of which are compared to give an indication of the quantity of the material dispensed in relation to a pre-set time. Should a variation occur from that desired the driving means, which comprises a sliplessly adjustable motor, is automatically adjusted to ensure that the desired delivery is achieved. The dispensing device A comprises upper and lower cylinders 1, 3 there being openings 4 communicating between them and a blade 11 for agitating the material to cause it to drop into the lower cylinder 3. A second agitator 12 causes the material to feed into a passage 14 from whence it is delivered into a discharge cylinder 7. The machine may be used for batch or continuous weighing.

Abstract: 1373240 Film reel drive RICOH KK 18 Nov 1971 [21 Dec 1970] 53496/71 Heading G2E A drive mechanism for a reel to reel film apparatus includes a driving mechanism (not shown but connected to shaft 57a) coupled to two reels 13, 41 whose mounting shafts 11, 43 include one way clutches which transmit the drive only when the particular reel is taking up film and which re-engage the free-wheeling reel when the drive stops. As shown shafts 11, 43 are coupled to shaft 57a by pulleys and belts. These may be replaced by gears. The driving mechanism may be a reversible D.C. motor or an A.C. motor with reversing gear. Fig.6 shows the shaft 11 with its  associated clutches, the assembly on shaft 43 is substantially the same, Fig.7 (not shown). The belt drive 61 applied to pulley 60 is transmitted by one way clutch 78 to the shaft 11 only when the reel 13 is taking up film. When the reel 13 is supplying film a brake shoe 77 acting on a brake wheel 75 provides a retarding force to the freewheeling reel 13 via one way clutch 74 (acting oppositely to clutch 78). This helps prevent the film slacking between the reels 13, 41. Such a mechanism can be used in a device such as that disclosed in Specification 1291668.

Title: Camera exposure time and shutter control circuits
IPC: G03B7/083
Filed: 1973-11-21
Abstract: 1423274 Exposure control circuits ASAHI KOGAKU KOGYO KK 21 Nov 1973 [22 Nov 1972] 54079/73 Heading G2A A circuit for controlling the exposure time of a camera has a photo-electric device for converting the intensity of incident light into a signal which is compressed logarithmically and then stored, the stored signal being expanded by a first timing circuit which commences operation with shutter opening, and a second timing circuit, adjustable in respect of various exposure factors, whose operation is initiated by the first timing circuit and which develops a shutter close signal. Fig. 3 is a block diagram of the circuit of Fig. 4, in which the exposure factor control is effected after the logarithmic expansion section, instead of before, as in known prior arrangements, Figs. (not shown) 1 and 2. When the main switch 19 is closed, the light received by the CdS photo-element 8 through the diaphragm 35 is converted and compressed by the logarithmic diode 9, and stored in the memory capacitor 13 through the normally closed switch 12. When the shutter release is pressed, switch 12 is opened and the front shutter curtain starts mechanically. A closed switch 16 is also opened, and a capacitor 15 starts to be charged through a transistor 14 which serves as a logarithmically expanding variable resistance element. When the voltage across capacitor 15 reaches a predetermined trigger level, transistor 22 of a Schmitt circuit comprising transistors 21 and 22 reverses from a conductive to a non-conductive state, so that transistor 27 is made non-conductive. Light received by a further CdS element 28 through a diaphragm 36 is controlled in dependence on exposure factors (e.g. film sensitivity), so that the varying internal resistance of element 28 acts as a timing resistor in charging a capacitor 29. This eventually triggers a further Schmitt circuit comprising transistors 30, 31, which energizes a coil 18 and so starts the rear shutter curtain. In the modification of Fig. 5 (not shown) the further CdS element 28 does not have a separate diaphragm but is arranged in the optical system so that the diaphragm serves both photoelements 8 and 28. In the modification of Fig. 6 (not shown), only a single CdS element is used.

In another embodiment Figs. 2 and 3 (not shown), there are four movable plates, and hence four internal reflections. The image - defining areas may be partially or completely reflecting, and may be alphanumeric in form.

Each receptacle comprises two members 12, 13 biased by a spring 27 to form an enclosure for the pile 3. A carrier 9 for the receptacle 2 is attached to the chain 1 and is guided by wheels 10 running in guideways 11. The opening and closing of the receptacle 2 is also controlled by pairs of coaxial tubes 18, 19 of which the inner tubes 19 are secured on a shaft 20 of the receptacle. The tubes 18 are connected to the clamping members 12, 13 and are rotated by camming slots 22, 23 engaged by a stud 24 having a follower 25 for engaging the camming members 7, 8. In a loading operation, Fig. 4, camming members 7 will have caused member 12 and spring 27 to be raised as the receptacle approaches a table 28 on which a pile of papers has been fed. As the clamping member 13 passes through spaces in the table 28, the papers are lifted clear of the table and, as the followers 25 roll off the camming members 7, the member 12 is lowered, under spring pressure, into engagement with the pile of papers. When unloading, the member 13 will overlay the member 12, and by the followers 25 engaging the camming members 8, the member 13 is raised to enable the pile 3 to be removed by a conveyer (not shown).

A six cylinder engine in which the firing order is 1-5-3-6- 2-4 exhausts into ducts 32, 34, 36, 38, 40 and 42. Ducts 32 and 34 merge to form a common duct 44 at the point 46, the duct 34 completely surrounding the duct 32 at this point. The common duct 44 then merges with the duct 36 at the point 48, the duct 36 completely surrounding the duct 44 at this point. The ducts 50 and 52 resulting from the mergers feed into the housing 54 of a turbine which is part of a turbo-charger. Figs. 5 and 6 show alternative constructions of the ducts at the point where they merge. In Fig. 5, the duct 56 surrounds 270 degrees of the duct 58 which in turn surrounds 280 degrees of the duct 60. In Fig. 6, the ducts 56 and 58 each surround 160 degrees of the duct 60. With the firing order given, the exhaust impulses occur alternately in each of the two groups of three ducts, so that each pulse aspirates each of the other two ducts in the same group. A similar arrangement for a four-cylinder engine is described.
