Patent GB-109238-A (GB)
Title: Method of Freezing Fish and other Food Substances.
Inventor: DAHL NEKOLAI
IPC: A23B4/06
Filed: 1917-05-31
Abstract: 109,238. Dahl, N. May 31, 1917. Cooling fish or other foods to be frozen in cases or moulds for storage. The cases are placed parallel tc one another in the moulds, and the cooling or freezing fluid is caused to flow through the moulds in a direction parallel with the longitudinal direction of the fish &c., instead of, as usual, in a transverse direction. In this manner, the fluid is brought into extensive contact with the substances, which, in the case of heavy or gutted fish, are liable to pack into a solid mass and become inaccessible when the fluid flows transversely. The moulds may be hung vertically and be provided with small apertures in their upper and lower ends, the apertures being plugged when freezing is completed.

Title: Electrical circuits for the production of subjective auditory effects
IPC: H03G5/20
Filed: 1947-03-21
Abstract: 649,709. Transmission systems. STANDARD TELEPHONES & CABLES, Ltd. March 21, 1947, No. 7818. Convention date, July 30, 1940. [Class 40 (iv)] To produce the impression of a wide band transmission whilst transmitting only a narrow band of frequencies the original signal is distorted by means of a non-linear device such as a grid-leak detector T1 (Fig. 1) and the distorted signal is transmitted to a low-pass filter F2 through a frequency-selecting and phase-shifting network L1, C3, R5 which is so arranged that its characteristic is varied at about 7 c.p.s. The filter F2 has a cut-off at 3,000 c.p.s. The distorted signal may be combined with an undistorted signal in a mixer T2 before the transmission is filtered. The frequencies picked up by the microphone M1 are amplified at A1 and are fed partly over a direct channel to the mixing valve T2 and partly through a high-pass filter F1 (cut-off 1000 cycles) to the detector T1. The output impedance of a reactance valve T3 is included in the parallel tuned circuit L1, C3, R5 so that the tuning may be varied periodically under the control of an oscillator O1 Modifications. The Specification describes various means for producing harmonics and changes in phase. Dry rectifiers, diodes, anode bend detectors or grid-leak detectors may be used as the non-linear device. The cyclic variation in the phase-shifting may be controlled thermionically as in Fig. 1 or mechanically as in Fig. 5. In the arrangement shown in Fig. 5, the middle and lower frequeiicies are picked up by a microphone M2 and are fed to the mixing valve T2. The highfrequencies picked up by microphone M1 are amplified at B1 and rectified by diodes T8, T9. The rectified output of T8, T9 is applied through a reactance valve T7 to a beat frequency oscillator 03 so as to frequency-modulate the output thereof. A reactance valve T6 and a beat frequency oscillator 02 constitute a second stage of frequency-modulation to which is connected a grid-leak detector T1. The output from T1 is fed to the mixing valve T2 over a phase-shifting network comprising a resistance R5, an inductance L1 and a motordriven condenser C3. In another arrangement, Fig. 7, distortion is produced by a grid-leak detector T4 and the phase-shift is controlled by a voltage fed back to the grid of T10 about 90 degrees in advance of the plate voltage. The valve acts as a variable inductance in parallel with L1 of the tuned circuit L1, C3.

Abstract: 1427349 Winding apparatus FATHOM OCEANOLOGY Ltd 21 Feb 1973 [29 Feb 1972] 8445/73 Heading B8B [Also in Division B7] Apparatus for launching, towing and recovering a submersible towable body 100 from a vessel comprises a saddle assembly 104 for the body when stowed, a towing winch assembly 108 and a towing cable guide sheave 114, all mounted on an A-frame skewable from a position in which the body 100 is stowed above the level of the vessel deck 219, to a position in which the body 100 is held by the saddle assembly 104 below water level ready for release for towing. The frame comprises a pair of parallel transom arms 206 pivotally mounted on an axis 200 at the rear of the vessel and below the deck level, and a deck frame 110 pivotally connected at one end to the transom arms on an axis 218 about which the sheave 114 is freely rotatable and restrained at the other end by a roller bearing 202 on the deck 219. The front of the deck frame 110 is supported on a deck support 204 in its stowed position, but as the frame 110 slides rearwardly and downwardly under the control of hydraulic cylinders 214, to place the saddle and body 100 into the launching position the deformed A- frame is supported only at the bearing 202 and pivot 200. Upon paying out cable from the winch 108, the saddle 104 gravitationally pivots  about the sheave axes 218 to place the body 100 below the water level whereafter further cable is payed out and the body becomes free for submersible towing, the A-frame then being lifted back up into its stowed position.

In the embodiment shown, a column 12 carries a bracket 14 on which is mounted, by bolts incorporating rubber or other vibration-absorbing material (see Group XXV), a plate 89 with a depending flange; a feed-off-the-arm sewing-machine 29 is fixed to the flange with its work-arm below the bracket 14, and a driving motor 39 for the machine is mounted on the plate by bolts passing through vibration-absorbing sleeves in the motor base and engaging slots in the plate so that the motor can be adjusted to tighten the belt 42 by which it drives the machine 29. The bracket 14 is roughly L-shaped in plan, one limb lying to one side of the column and carrying the motor while the other extends to the front of the post and carries the machine 29 on the side opposite to the first limb; the part adjacent to the machine is made thicker, to reduce vibration. The clutch by which the motor drives the belt pulley is actuated by a treadle 57 pivoted on the base carrying the column 12, through a rod passing up the column and resiliently engaging the clutch-actuating yoke 64. Another treadle 56 serves to lift the presser-foot of the machine. A hand-wheel 47 has a stem with a socket screwed on to the end of the shaft of the driving pulley.

The filter device may be mounted in a domestic water purification apparatus such as illustrated in Figures 1 and 2 (not shown) as described and claimed in Specification 1448844. The filter means 68 and 70 may be in the form of porous polyethylene discs, filter 68 having pores of about 35 microns diameter and filter 70 pores of about 10 microns diameter. The particulate filter material may be activated charcoal which may be coated with bacteria-preventing means, e.g. metallic silver or a silver salt, or it may be one or more ion exchange resins or a mixture of silvercoated activated charcoal and ion-exchange resin. If the particulate filter material comprises ion exchange resins, then a dye indicator may be provided to show when the resins are depleted, the housing being transparent for this purpose. Suitably, the thickness and porosity of filter 68 are chosen such that that filter becomes clogged with separated particulate matter at the same time as the particulate filter material becomes depleted. The combination of the filter device with a non-positive displacement pump will ensure cessation of water flow when this happens.
