[Class 97 (iii).] A hygroscopic element for use in humidity control apparatus comprises a strip of hygroscopic material wound backwards and forwards between two sets of rollers mounted in end frames, the rollers of one set lying opposite the spaces between the rollers of the other set when the frames are in their normal positions so that the sections of strip lie parallel to one another. In the form shown in Fig. 1, each end frame comprises a channel member 2 from the web 7 of which a pair of lugs 6 are bent up. The flanges 3 of the member 2 are each provided with a row of holes 4 for the reception of rollers 13, which are retained in position by a channel shaped spring clip 9. The invention also includes a method of assembling the hygroscopic element in which the members 2, 2<1> are held apart in end frame clamps 16, 16<1>. The lowermost roller 14a, which is of smaller diameter than the intermediate rollers, is inserted in the member 2<1> and the strip 15 of hygroscopic material, preferably beaten paper cut transversely of the web, looped round and stuck with adhesive. The strip 15 is then passed round a pulley 27 the frame 26 of which is attached by a cord passing over pulleys 25 to a weight 27 so that the strip the other end of which is clamped at 28 is maintained at uniform tension, whilst the remaining rollers are inserted successively. The strip is looped round the last roller 14b also of smaller diameter than the intermediate rollers and held, together with the last strand, between the clamping arms 32 whilst it is cemented to form a loop. The clips 9 are then applied to secure the rollers in position and the end frames removed from the clamps and held apart under tension while the strip is treated with atmospheres of varying humidity.

Title: Arrangements for suppressing parallel oscillation in push-pull amplifiers and oscillators
IPC: H03F3/28
Filed: 1939-12-15
Abstract: 537,300. Valve circuits. STANDARD TELEPHONES & CABLES, Ltd., HILL, F. R., and SAMSON, G. G. Dec. 15, 1939, No. 32304. [Class 40 (v)] In a push-pull amplifier or oscillator, spurious oscillation in,the parallel anode is prevented by the provision of a negative feedback circuit which reduces the gain in the parallel anode but which has substantially no effect upon the gain on the push-pull anode. In the case of an oscillator the feed-back is in regenerative phase. The first push-pull stage of a Class B audiofrequency amplifier is shown in which negative feedback for reducing distortion in taken from the final stage (not shown) and applied to the grid circuit of the valves V, V1 of the first stage through a wide range transformer T, and input bridges B. Negative feed-back is also applied by means of an unbyepassed cathode resistance R which feed-back reduces the gain of the stage for parallel operation without affecting the gain for push-pull operation. The increase in grid bias is offset by applying a positive voltage to the grids of valves V, V1 by means of a potentiometer P across the plate supply. Alternatively the resistance R may be of a value to give the desired grid bias, and a choke in series with the resistance may be used for the negative feed-back.

Title: Improvements in or relating to record card feeding apparatus
Inventor: BAILEY ERIC
IPC: G06K13/12
Filed: 1959-09-24
Abstract: 958,563. Feeding sheets. INTERNATIONAL COMPUTERS & TABULATORS Ltd. July 7, 1960 [Sept. 24, 1959], No. 32500/59. Heading B8S.  Statistical record cards 1 are fed from a magazine 2 by a reciprocating picker knife 3 on to a reciprocating carriage which advances the cards stepwise to a card stacker 10, via processing station 8, and which locates the cards solely by means of a rear stop 4, the arrangement being such that each card remains in the same plane during its passage through the device. Stop 4 is pivoted about a horizontal axis, and is spring urged downwardly so that, with the carriage stationary, the picker knife moves a card under, and beyond, the free edge of stop 4 during each outward stroke, and during the return stroke, it moves the card rearwardly into abutment with the said free edge. This slight reverse movement of the card is effected by the frictional engagement of that portion of the card adjacent a pressure roller 5 with a block 7 carrying the picker knife. As shown, the processing station comprises a brush sensing device similar to that described in Specification 796,685 which exerts a frictional force on the card to retain its trailing edge in contact with stop 4, but in a modification (not shown) the station comprises a photo-electric sensing device and springs are provided to produce the frictional force. The cards are transferred from the carriage to the stacker by pressure rollers 11, 12, and are aligned in the stacker by a spring blade 16, and a pivoted end wall 19 provided with resilient buffer strips 18. Specification 362,529 also is referred to.

Filed: 1976-08-04
Abstract: 1534082 Camera shutter SEIKO KOKI KK 4 Aug 1976 [6 Aug 1975(2)] 32511/76 Addition to 1534081 Heading G2A A shutter has a drive member 9 coupled by a connecting member 10 to an opening actuator 4 for moving opening blades 3 to initiate an exposure; closing blades 6 movable by a closing actuator 7 to terminate the exposure; means 7c for releasing the connecting member 10 just before, at or after exposure termination; and means 7d for transmitting drive from the closing actuator 7 to the opening actuator 4 to return the opening blades 3 to a position in which they at least partially close the shutter aperture 1a. The engagement of parts 7c, 7d of the closing actuator 7 with the connecting member 10 and opening actuator 4 slows the closing actuator 7 and thereby reduces rebound of the closing blades 6. Also, if the closing blades 6 do rebound, light is blocked by the opening blades 3. In Fig. 4 (not shown), the opening actuator 4 and connecting member 10 are inter-connected by a spring (210f). When the closing blades 6 terminate exposure, projection 7c on the closing actuator 7 releases the connecting member 10, projection 7d turns the opening actuator 4 ACW to partially close the aperture 1a and then the spring (210f) turns actuator 4 further ACW to complete closure. In Figs. 5, 6, 7 (not shown), when the closing blades 6 terminate exposure, projection 7c on the  closing actuator 7 pushes the connecting member (310) ACW and a projection (310d) of the connecting member turns the opening actuator 4 ACW. to return the opening blades to the closed position.
