Saws.-A hack-saw frame is provided with a pivoted catch or projecting tongue adapted to coact with a toothed disc rigid with the bladeholder, or with equivalent means, for the purpose of locking the blade in different angular positions independently of its tension, the rear threaded end of the blade holding spindle being forked or provided with a cross-pin to cause the handle to bind thereon when the tensionof the blade is relaxed by turning back the handle, thus enabling the angular adjustment of the blade to be then effected by a further turn of the handle. As shown in Fig. 1, the blade is held by hooked pins on spindles C<1>, C<2>, carried in feet B on the frame A. The spindle C<2> is provided with retaining-pins D', D<2>, and the threaded spindle C' is fitted with a notched disc E engaged by a catch K pivoted at L. By slackening the handle J, which contains a nut H threading on the forked rear end G of the spindle, and raising the catch K, the spindle C<1> may be turned to adjust the angular position of the blade. In the modification shown in Fig. 2, the foot B is provided with a fixed projecting tongue K from which the notched disc E may be disengaged by pushing the spindle C<1> forward after the handle has been slacked, whilst in the further modification shown in Fig. 4 the locking of the spindle C<1> is effected by means of a pin X engaging notches W in the foot B. In both these modifications the spindle C' is provided with a cross-pin V to enable the handle J to bind thereon, and slotted sleeves N, fixed by nuts S, M, are fitted on the spindles C<1>, C<2> to prevent the blade slipping off the hooked pins when its tension is relaxed sufficient to release the locking device.

Filed: 1929-08-06
Abstract: 339,641. Woodall-Duckham (1920), Ltd., and Duckham, A. M. Aug. 6, 1929. Coke ovens.-In coke ovens or other gas.fired furnaces in which heating is effected by vertical combustion flues, the heating gases pass upwards towards the top of each flue and return as burnt gases down the same flue, leaving at the bottom end through a heat exchange apparatus. In the construction shown in Figs. 5 and 6 two burner nozzles I‹ direct the flames along the walls of the flue next the adjacent ovens, and the heating gases are guided along their up and downflow paths by ribs B‹. Reversal of flow at the upper end is facilitated by shaping the top of the flue to guide the two streams of gases inwardly. The nozzles I‹ form the tips of a recuperator element similar to that shown in Fig. 3 for a flue having a single burner nozzle supplied with rich gas. This element is in the form of a three-tube structure carried on a hollow base F which is supported on removable plates G so that it can be withdrawn bodily from the oven. A packing H makes a gas-tight joint round the base, and gas is supplied to the middle tube by the nozzle L. The outflowing gases pass around the air conveying tubes E<1>, and are exhausted through the flues D. In the modified form of element shown in Fig. 4 the recuperator tubes E<1>, E<2> for two heating-flues are supported on a common base F, which is subdivided so that both air and lean gas can be preheated. The outlet nozzles I may be interchangeable.

Abstract: 1379356 Measuring elastomeric properties electrically B F GOODRICH CO 22 May 1973 [23 May 1972] 24326/73 Heading G1N Apparatus for measuring the elastomeric properties of a test sample of material comprises a matching stator and rotor, and means for measuring the stress in the sample when it is compressed between the stator and rotor to a predetermined pressure and the rotor is given a predetermined angular twist. As shown, the stator 26, Fig.1, with a conically shaped recess, is lifted by a piston-rod 17, Fig.2, in line with the rotor 27, which is attached to a shaft 28 for rotation by linear movement of a piston-rod 37. The stator and rotor incorporate electric heating elements and temperature sensing units to adjust the sample temperature before stress measurements are made. The torque in the linkage to the rotor 27 is measured by a load cell 36, e.g. bridge-connected strain gauges, and the peak value is detected at 83, Fig.8, and shown on a meter 48. The peak value is also developed across a potentiometer 102, and 37À5% of this value, selected by slider 103, is compared in amplifier 99 with the con-  tinuing signal from the load cell 36. When they are equal a counter 49 is stopped and its indication represents the time interval for the peak stress to fall to 37À5% of its value. The area under the stress curve is also integrated at 107 for a period of 2 seconds, determined by multi-vibrator 110, and the result shown on meter 50.

Abstract: 1,216,016. Laminated filter. JOHNSON & JOHNSON. 22 May, 1968 [22 May, 1967], No. 24399/68. Heading B5N. [Also in Division B1] A filter comprises a first fibrous layer, having a weight of between 100 and 400 grains per square yard and being formed of between 5 and 20 denier fibres, and a second fibrous layer, having a weight of at least 75 grains per square yard and being formed of between 1 and 3À5 denier fibres, a cleavage plane along which the filter media may be split existing either within the second fibrous layer or at the interface between the two layers. The filter is for use in the filtration of milk, the leucocyte count of which may be determined by a visual inspection of the surface of the second fibrous layer exposed after cleavage. The fibrous layers may be stabilized with a binder. The difference in denier of the fibres of the two layers renders the filter readily cleavable between the two layers. However, additional means for ensuring easy and clean cleavage may be provided, e.g. by controlling penetration of the binder at the interface between the layers, by interposing a thin layer of large diameter fibres within the second fibrous layer or by providing a marginal tab for initiating splitting along the cleavage plane. The fibres of the first and second layers respectively may be synthetic and cellulosic. The use of rayon, rayon/cotton and cotton layers is disclosed. As shown, the second fibrous layer 16a is constituted by three zones 19, 20, 21 of progressively finer fibrous material, e.g. of blended rayon and cotton, rayon and cotton respectively. Gauze covering layers 22, 23 are provided and breakably sealed to each other beyond the edge of the fibrous layers.

Title: Improvements in or relating to the recovery of ethyl alcohol
Inventor: JONES HOWELL HENRY MONTAGUE
IPC: C07C29/74
Filed: 1948-09-20
Abstract: <PICT:0677989/III/1> Ethyl alcohol is recovered from a mixture of gases and ethyl alcohol vapour by injecting steam into a conduit which is in communication with the mixture and with a fractionating column containing condensed portions of ethyl alcohol/water mixtures of varying composition, whereby the steam discharges together with the mixture of gases and alcohol vapour into the column, and removing aqueous ethyl alcohol from the top of the column.  Mixed air and ethyl alcohol vapours are ejected from a rotary filter (not shown) into a fractionating column 3 by a steam ejector 2. Alcohol rich vapours at the top of the column pass to a water-cooled condenser 5 and part of the condensate is refluxed to the column via line 7. Liquid at the bottom of column 3 falls into a stripping column 8 fed with steam at 9 and water is removed from the bottom of this column. At the beginning or end of the filter period when a large quantity of air is ejected by the ejectors 2 the mixed air/steam/alcohol vapours pass directly via line 11 to the condenser 5 and the condensate is later fed back to the column at constant rate.
