Title: Improvements in and relating to machines for cutting cross trenches or gains in wood
IPC: B27F1/06
Filed: 1934-02-01
Abstract: 427,994. Trenching wood; tenoning wood. ROBINSON & SON, Ltd., T., and TWEEDALE, J., Railway Works, Rochdale. Feb. 1, 1934, No. 3332. [Class 145 (i)] A machine for cutting cross trenches or gains in wood comprises an overhead beam spanning the chain or like feed mechanism, the beam supporting a number of individually adjustable gaining heads on both sides of the beam, each head comprising a cutter offset laterally from a casing adjustable about a vertical axis, the cutters being thus capable of adjustment to cut overlapping or closely adjacent, square or angular trenches. The invention is shown as applied to a double end tenoning machine having tenon cutter blocks 34 and feed chains 15 above which extends a beam 12 having on both sides slideways 17 for carriers 18 which are adjusted along the beam by handwheels 22. Each gaining head is mounted with vertical adjustment, by a screw and handwheel 23, on a face plate 24 rotatably mounted on the carrier 18 and held in adjusted position by a screw 25 ; each gaining head is thus adjustable along the beam to alter the position of the cut, vertically to vary the depth of cut and about a horizontal axis to determine the angularity of the trench. Each gaining head comprises a cutter block 26 mounted on a spindle 27 projecting from the side of a casing 35 which is adjustable about a vertical axis so that the cutter block 26 can be to the right or to the left of the vertical slide. Each cutter 26 is driven through bevel gears 28 by an electric motor 30. Each gaining head has pivotally secured thereto at 31b two sockets 31a for members 31 which carry at their lower ends a shoe 32 to hold the work down during the cut.

Title: Improvements in or relating to gas flow indication in breathing systems
Inventor: HAMLIN HUMPHREY ALBERT SAMUEL
IPC: A62B9/00
Filed: 1963-01-26
Abstract: 992,766. Respiratory appliances. NORMALAIR Ltd. Jan. 23, 1964 [Jan. 26, 1963], No. 3334/63. Heading A5T.  A pressure-actuated, periodic flow indicator is associated with a breathing system incorporating an economy arrangement whereby ambient air is admitted during the latter part of each inhalation phase. Breathable gas is passed through an inlet pipe 1 to a constriction 2 and thence to a demand regulator 3 and face mask. The constriction 2 limits the rate of flow of gas and, at each inhalation, the flow is insufficient to meet the demands of the user and the resultant drop in pressure, downstream of the constriction, causes an air inlet valve on the mask to open and admit ambient air to the user. In accordance with the invention the two chambers 5a, 5b, on each side of a diaphragm 6 in a chamber 7, are connected between the constriction 2 and regulator 3 by a pipe 5, one connection, from 5a, including a constriction 9. With this arrangement the pressure drop caused in the pipe 5 by inhalation is communicated to chamber 5b more rapidly than to chamber 5a owing to the constriction 9 and consequently the diaphragm 6 is raised and closes electrical contacts 13 to give a suitable indication. During exhalation, no gas flows through the regulator 3 and pressure is built up in the pipe 5 and chambers 5a, 5b by gas received through the constriction 2. In this case the rapid return to normal of the diaphragm 6 is ensured by a lightly-loaded, oneway valve 14.

A document storage device comprises a. plurality of open-topped boxes disposed sideby-side in a drawer or the like. each box consisting of two covers which may be spread apart when the box is raised from the device and engaged with the covers of adjacent boxes or the end walls of the drawer to hold the box in the raised position. Papers are filed in opentopped boxes contained in a drawer or compartment 1. Each box comprises two covers 2 having side walls 3, end walls 4, and bottom walls 5, hinged together at 5a. The end walls and bottom walls of each pair of covers are provided with interengaging projections 6 and notches 6a. In addition, the end walls have recesses 8 adapted to engage the upper edges 9 of the adjacent boxes, or a member 10 on the end wall of the drawer so that each box may be held in a raised position with its covers spread apart. A bar 7 fixed to the hinge or bottom walls of each box enables the box to be lifted. In a modification, Fig. 4 (not shown), the end walls have projections 12 which project beyond the covers when the latter are spread apart, to engage apertures 15, 16 in the adjacent boxes or compartment walls and hold the associated box in a raised position. Alternatively, each pair of covers is formed as a one-piece moulding. The covers are resilient and tend to spring apart when the box is raised from the compartment. Fig. 5 (not shown). Springs 18 enhance this tendency. One cover of each pair carries a filing post.

Filed: 1929-02-06
Abstract: 305,987. Telefunken Ges. f³r Drahtlose Telegraphie. Feb. 13, 1928, [Convention date]. Fading, preventing. - Several spaced aerials A1, A2, A3 are coupled through amplifiers V1, V2, V3 to rectifiers g1, g2, g3 supplying corresponding grid-biassing voltage to valves R1, R2, R3 branched in parallel across a common alternatir.g-current circuit K fed from a source H generating a frequency in the neighbourhood of 5000 cycles per second. Energy received on any one or more of the aerials reduces the resistance of the corresponding valve R1, R2 or R3, and so increases the value of the alternating current flowing through a resistance w which is coupled to the final receiver J. The value of the resistance w is made high relatively to that of the shunt valves so that it operates as a limiting device, the receiver being operated by substantially equal currents no matter how many of the aerials are excited. The arrangement is particularly suitable for short-wave morse or picture signalling.

Title: Method for the manufacture of hydrogen peroxide solutions having a high electrical resistance
IPC: B01J47/04
Filed: 1956-02-10
Abstract: Hydrogen peroxide solutions having a high electrical resistance are prepared by contacting industrial hydrogen peroxide solutions in a single bed with a mixture of an anion exchanger in hydroxyl form and a cation exchanger in hydrogen form at approximately 0 DEG  C., e.g. -4 DEG  to 7 DEG  C., the quantity of anion exchanger having a breakthrough capacity equal to that equivalent to the quantity of anion impurities in the solution and the cation exchanger having a breakthrough capacity larger, preferably at least 5 times larger, than that equivalent to the cation impurities in the solution. The cation exchanger is water-washed, treated with dilute acid, and water-washed until acid free.  The anion exchanger is treated in the same way and is then activated by treatment with alkali, and water - washing.  The cation exchanger may be strongly acid resin containing free SO3H groups, and the anion exchanger may be strongly basic resin of the amine or quaternary ammonium types.  The exchangers may be treated, after mixing in the column, with dilute hydrogen peroxide, e.g. 0.1-1.5% for 48 hours, and the exchanger mixture is filled with water before use.  The solutions may be treated fractionally and the separate fractions collected.  The exchanger mixture is regenerated by reverse washing with water, treating with alkali solution to reactivate the anion exchanger and exhaust surplus cation exchanger, reverse water-washing to separate the two resins as two layers, reactivating the cation exchanger with acid, water-washing and mixing the exchangers by air blowing during the the reverse washing.  After a number of contacts the capacity of the anion exchanger may be decreased, when it should be subjected to the prolonged treatment with concentrated acid, e.g. 5N acid for 4 hours, before alkali reactivation.
