Abstract: 1,109,510. Sawing. SIMONS EMBALLAGEFABRIEKEN EN HOUTHANDEL N.V. 21 Aug., 1965, No. 35974/65. Heading B5L. A method of sawing a round log 10 into timber comprises turning the log into the proper position on supporting rollers 20 operatively mounted on the carrying arms 19 of a feed carriage 17, putting the log on the pointed supports 7, 9 of a support device 1 by means of the carrying arms, clamping the log to the supports by biasing members 11, 12, and passing the log through a band-saw machine having a plurality of simultaneously operating band-saws, the supports passing between the band-saws. As described, the apparatus for carrying out the method has two pairs of band-saws 5, 6, the leading pair 5 being spaced apart a greater distance than the pair 6. The pointed supports 7, 9 are carried by a carriage 1 secured at one end to a portion 2 and adjustably secured at the other end to a portion 3, the portions having considerable width and engaging rails. The biasing members 11, 12 are mounted on pivots 13, 14 on the portions 2, 3 and are urged by devices 15, 16 to clamp the log against the pointed supports 7, 9. A third pointed support 8 is urgable upwardly against the log by a pneumatic or hydraulic device. During a sawing operation, the ends of the levers 11, 12 pass between the saws so that the whole length of the log can be cut. The logs to be sawn are brought by a conveyer 21 having a catch 22 for controlling the speed to the feed carriage 17 which is movable transversely of the carriage 1 on wheels 18 and has a pivoted carrying arm 19 provided with a chain drive to convey the log to the support rollers 20 drivable to rotate the log to the most favourable position for cutting. The carriage is movable to position the log above the pointed supports 7, 8, 9 where it is clamped by the levers 11, 12. The carriage 1 is then moved to carry the log past the saws 5, 6, the cut pieces falling on to spiral rollers 26 which carry the pieces outwardly so that they fall on to a conveyer 27. The remaining timber, after release by the levers 11, is lifted from the supports 7, 8, 9 by pivoting of the arms 25 of a discharge carriage 23 movable on wheels 24. In another embodiment, the carriage 1 is replaced by an endless chain 31, Fig. 4 (not shown), entrained about drums 32, 33 and having pointed supports 37 on to which the log 40 to be cut is pressed by means (not shown).

As shown the grooves 1 extend axially and each groove has a depth between # and ¢ of its width (Fig. 2, not shown). Fig. 3 (not shown) illustrates alternative groove arrangements. The grooves constitute at least 80% of the circumference of tube 40. Slurry is pumped into annular chamber X through conduits 41, 42, 49 and 48. A siphon (not shown) removes filtrate from inside tube 40. After filtration jack 54 lowers tube 40, whereupon the filter cake, which is segmented by the pleated form assumed by the element 50, falls away. Air blasts through tube 53 and/or the elasticity of element 50 may assist cake removal. Element 50 may comprise a basic wire mesh tube enclosed by a tube of polyester felt which supports an outer tube of resilient woven polyester. Mesh sizes and gauges are exemplified. The construction avoids the difficulties of fitting an accurately made element tightly on to its inner tube.

Title: Smoke detectors
IPC: G08B17/107
Filed: 1975-09-03
Abstract: 1489128 Smoke detector NOHMI BOSAI KOGYO CO Ltd 3 Sept 1975 [3 Sept 1974] 36333/75 Heading G1A In a smoke detector a comparator 24 stores a reference voltage which is compared by a differential amplifier 27 with the voltage V 1  from a photodiode 15. The effects of spurious signals (due to the occasional occurrence of flashing lights) is mitigated by a transistor 40 connected in parallel with the capacitor 24 driven by a series combination of a diode 41 capacitor 42 and resistor 43. The result is that when the first positive half wave peak of the spurious signal reaches point P the transistor 40 is switched on for a predetermined period. This drains some of the charge on the capacitor 24 so that the resulting current due to the spurious signals does not charge the capacitor 24 to past the reference voltage. The first positive half wave peak of the spurious signals also charges the capacitor 42 which slowly discharges via the reverse bias resistor of the diode 41 and which keeps the transistor 40 turned off in the meantime. The capacitor 24 is initially charged to its reference voltage via a low pass filter 20 comprising resistor 21, capacitor 22 and diode 23. The reference voltage is applied via a F.E.T. 25 to the differential amplifier 27 which receives the amplified (16) output of the photo-diode 15 which depends on the amount of light reaching it from a source 10. The beam intensity may be attenuated by the presence of smoke and when this occurs the differential amplifier 27's output changes and turns on a transistor 30 which activates a relay 32 and then a relay 35 which produces an alarm signal. Modifications of the circuits are described employing a photo-resistor, Fig. 3 (not shown), and an ionization chamber, Fig. 4 (not shown).

Abstract: 1,221,986. Switching systems for consuming devices; control of motors. CUTLER-HAMMER Inc. 31 July, 1968 [31 July, 1967 (2)], No. 36522/68. Headings H2H and H2J. [Also in Divisions G1 and G3] Circuit for controlling the power supplied to a load from an A.C. source includes means for varying the firing angle of a gated control element in response to changes in an external condition or in a condition of the load. In the circuit shown in Fig. 1, the firing angle of a triac 4 may be set manually by adjusting a variable resistor 6. This adjustment determines the time taken each cycle for the potential at a point X to reach the breakdown voltage of a diac 12 connected to the gate of the triac. Two capacitors 8, 10 are connected in series with the resistor 6, and a device 14 leaks current from the capacitor 10 to control automatically the timing of the breakdown of the diac. The device 14 may be a thermistor, in which case the circuit is particularly suitable for controlling the energization of a heater or cooling fan. Similarly the circuit may be arranged to compensate for variations in the supply voltage by using a photo-cell as the device 14 and allowing the photo-cell to receive light from a lamp energized by the supply, Fig. 2 (not shown). Such a circuit may be used to regulate the speed of a motor or to control a lamp dimmer. The triac may be replaced by a thyristor and rectifier bridge, Figs. 3, 4 (not shown), and the condition responsive device 14 may take the form of a resistance bridge including a thermistor in one of the branches, Figs. 5, 6 (not shown). In such a modification, the resistance bridge controls the biasing of a transistor and so adjusts the current leaked through the transistor from the capacitor 10.
