IPC: B01F11/00
Filed: 1935-05-13
Abstract: 455,147. Concrete &c. mixers. POWEL & HILL, Ltd., POWEL, W. S., and HILL, F., 110, Canterbury Road, Croydon. May 13, 1935, Nos. 14037/35 and 7240 /36. [Class 86] Concrete and similar wet mixtures are made by mixing the materials in a dry state and then passing them to a mixer in which the water is added and which comprises a trough in which the materials are given a to-and-fro motion as they progress by means of rotary paddles. The dry materials are fed from a belt 8 on to a spring-mounted screen 9, vibrated by a shaft 11, and mounted over the trough 3. The materials fall to one end of the trough where they are further mixed in a dry condition by sets of paddles having opposite and nearly equal inclinations so that the material progresses slowly with a to-and-fro motion towards the other end of the trough where water is added by a perforated pipe and the difference in inclination between the sets of paddles is greater. The trough may be covered and the water may be added through the paddles.

Title: Improvements in trailers
IPC: B62D63/06
Filed: 1953-05-19
Abstract: 744,627. Trailer vehicles; arrangements of wheels and axles; turnable forecarriages; vehicle body mountings. BONNEL, H. A, and AMEYE, A. A. May 19, 1953 [May 19, 1952], No. 14069/53. Classes 108 (1) and 108 (2). A trailer has a forward pair of wheels 5, Fig. 4, mounted on an axle 5a, which is to the rear of a king-pin 4 so that the tractor supports a proportion of the trailer load, which proportion is determined by the position of the axle 5a relative to the pin 4. The position of the axle 5a may be altered by moving a transverse bar 14, having a housing for the pin 4, along the side frames 11 and locking the bar in position by means co-operating with one of a series of holes 13. In a modification, Figs. 9, 11 and 12, the rear wheels may be pivoted in pairs on each side, the wheels 22a, 22b, for example, being journalled at oppositely cranked ends 20a, 20b of a swing tree 20 pivoted by a bolt 19 through a bearing 18 to a support 17. By this arrangement it is stated that when one wheel of the pair enters a rut, only half the normal variation in axle level takes place which reduces the twisting couple on the chassis.

Title: Improvements relating to tuning indicators for radio receivers
IPC: H03J3/14
Filed: 1936-05-20
Abstract: 475,064. Wireless receiving circuits. COLE, Ltd., E. K., and BRADFIELD, G. May 20, 1936, No. 14258. [Class 40 (v)] Visual indication of resonance in a superheterodyne receiver is given by the production of a low beat-frequency, between the true and untrue intermediate frequency which controls the indicator. The output from the I.F. amplifier V2 is applied to the lower diode of the double-diode triode V3 and thence through the filter 4, 5, 6, and volume control 8, 9 to the control grid, the triode normally acting as a low-frequency amplifier. When the receiver is to be tuned to a given station, switches 12 22 are closed and switches 11, 18, 21 are opened, which may be effected by movement of the volume control or tuning knob. In this position the triode V3 oscillates at the true intermediate frequency by virtue of the back coupling 17, 10, the resultant beats produced with the false intermediate frequency from V2 (due to mistuning to a station in course of being tuned in), being applied over V4 and transformer 15 to the visual indicator 20. This is constituted, as shown in Fig. 2, by mechanical low-pass filter, comprising a spring 23 with laminated core 25, and is tuned to resonate at a beat-frequency below 300 cycles / sec. A mirror 26 having non-reflecting strips 28 and reflecting strips 29, is mounted within the spring to reflect light from the source 27. When the spring is stationary the strips 29 are obscured by the spirals of the spring 23, but when the latter begins to resonate, (which takes place when the desired station is less than 300 cycles off-tune, the reflected light from strips 29 becomes visible. Switches 11, 18, 21 are then closed and 12 and 22 opened V3 thereby resumes its amplifier function and the loud-speaker is rendered operative. The spring 23 may carry loading weights to act as a mechanical transmission line.
