Title: Improvements in and relating to the drying of vegetables
IPC: A23L19/15
Filed: 1939-12-15
Abstract: In the process according to the parent Specification the cooling of the cooked vegetable is to a temperature less than 4 degrees C., which facilitates segregation, and, in consequence, the preliminary removal of, moisture, and also minimises damage to the grains of the cooked vegetable when mashing, stirring or sieving it. Advantageously the cooling temperature is sufficiently low to cause freezing of the water present.  If frozen, the cooked vegetable is subjected to gentle artificial heat before or during the preliminary removal of moisture, e.g. by centrifuging or under reduced pressure.

Title: Improvements in screw-thread gauges
IPC: G01B3/48
Filed: 1939-12-16
Abstract: 533,999. Screw thread gauges. COVENTRY GAUGE & TOOL CO., Ltd., HARLEY, S. J., and WAINWRIGHT, J. E. Dec. 16, 1939, No. 32351. [Class 106 (ii)] The gauge comprises a plurality of gauging elements mounted so as to be free for rotation about parallel axes and each formed with a series of circumferentially discontinuous external serrations. A cylindrical block 2 on a holder 4 has a deep diametral recess 7 at the sides of which are located pins 6 parallel to one another and to the axis of the block. Loosely mounted on the pins are hollow rollers 3 having thread form serrations 5 discontinuous circumferentially. If necessary, the pins may be connected by a tee plate 8. The pins are fastened to the bottom of the block by their eccentric several stems 19 and nuts 22. The gauge is inserted into the work with the interrupted portions of the thread facing outwards, the rollers being afterwards turned to engage the work thread by using spring clips 11 sprung into grooves in the rollers. The feel of the contact may be judged in this manner and the sharp edges of the interruptions will serve to clear the work of any matter left in the thread. In a modification two hollows are made in the block at the ends of a diameter and the rollers located therein depending towards the holder 4. In this form the spring clips 11 may be connected to be simultaneously moved. In a further form the rollers have knurled ends instead of clips 11. The threads of the rollers may be interrupted at two places on opposite sides and the threads made of slightly different sizes to afford a " go " and ''no go gauge. The eccentric mounting admits of slight adjustment.

The mixture of base colour composition and variegating granules is applied to a foundation material 2, which may be burlap or waterproof felt, through a stencil 3 comprising a grid of wires 14, 15 to which solid members 16 are fixed to provide openings in the body layer, these being subsequently filled in with the variegating colour compositions as the web is stationed successively below stencils 4 to 9, each of which is in the form of metal plates, such as 18, Fig. 4, having therein apertures such as 17, which correspond to some of the solid members 16 of the stencil 3. In certain cases, two apertures in different stencils may be used for filling a single opening in the body layer. The completed pattern then receives a light pressing at 10 before proceeding to hydraulic presses such as 11 and 12 and curing if required. The body layer may be composed of a singlecolour linoleum composition having granules, all of which will pass a 5-mesh per inch screen, with which minor proportions of compositions of the variegating colours, having the same size of granule, are mixed. The mixes for the inlays may be of finer granule size, and sieved to remove particles which will not pass a 6 to 8 mesh per inch screen.

Abstract: 398,056. Electric signalling and remote-control systems. HORABIN, W., Rock House, Stanton-Gate, Derbyshire. Nov. 19, 1932, No. 32730. [Class 40 (i).] The closure of a signalling circuit energizes a relay which completes a secondary circuit including a signalling device, such as a bell, and a slow-to-energize relay, which, on fully energizing, breaks the circuit of the signalling device and connects up a second device, such as a lamp, or completes a control circuit. When the wires 10 are connected, either by means of a switch 13 or by clipping the two wires together, relay 12 energizes, connecting relay 17 and a bell, not shown but connected across 21a, 21b, to the electric power leads connected to 16a, 16b. After a predetermined time, adjustable by dashpot 23, relay 17 makes contacts 26, 27 and breaks contacts 19, 20, replacing the bell by lamp 25. The lamp 25 may be replaced by a control circuit. The condenser 28 eliminates sparking.

[Class 37.] The apparatus for measuring average voltage of a consumer's circuit according to the parent Specification is modified by providing the timemeasuring device in the form of a time switch which operates on the counter of the time device and on the setting of the meter. The counters of the meter and switch are provided with zero-setting mechanism which may be operated electrically or mechanically. In a further modification, a magneto motor meter replaces the wattmeter, a friction or other coupling with the time switch being provided, this arrangement being provided on continuous current circuits. In one construction, Fig. 1, riders 22, 23 on the dial 21 of the time switch engage with a star-shaped member 24 to rock a lever 26 for disengaging the gear of the switch counter 33 and for braking the meter disc 15 by a brake-block 34. In a modification, the star member 24 closes the voltage circuit of the meter and energizes a relay the armature of which effects disengagement of the switch counter gear. A further modification, Fig. 3, shows a magneto motor meter 45 comprising a rotating coil 48 and permanent magnets 46, 47. The rotor shaft drives the meter counter 17 and also the time counter 33 through a worm 50 and friction clutch 54, the friction clutch being energized by a relay connected to terminals 55. The zero-setting shaft may also be actuated by a relay 56, or it may be actuated mechanically by a key engaging the part 57. The relay 56 and clutch-operating relay are connected in parallel across the main circuit and are closed by engagement of the riders 22, 23 and star member 24.
