Title: Pyrimidinyl-guanazoles
IPC: B01J31/08
Filed: 1961-07-31
Abstract: The invention comprises compounds of the formula: <FORM:0950521/C2/1> (wherein R1 and R3 are hydrogen atoms or alkyl or alkoxy groups, R2 is a hydrogen or halogen atom or an alkyl or alkoxy group, and R4 and R5 are hydrogen atoms or alkyl, aryl, alkoxyaryl or halogenoaryl groups or one of them is a carboxylic acid acyl group and the other a hydrogen atom, said alkyl and alkoxy groups each containing at most 5 carbon atoms) and non-toxic salts thereof; and their preparation by; (1) reacting a 2-hydrazino -4-R1-5-R2-6-R3 pyrimidine or salt thereof with an N-R5 dicyandiamide (wherein R5 can have any of the above values except acyl); or (2) reacting a 2-halo-4-R1-5-R2-6-R3-pyrimidine with an N-R4-N1-R5-guanazole (wherein R4 and R5 can have any of the above values except acyl); or (3) reacting an N-R4-N1-R5-1-guaryl-guanazole (wherein R4 and R5 can have the same values as in (2)) with a compound of the formula: <FORM:0950521/C2/2> (wherein Z and Y each represent an oxo group, imino group, two halogen atoms, two alkoxy groups or both a halogen atom and an alkoxy group, and W is a hydroxy or alkoxy group); or (4) acylating a product obtained by process (1), (2) or (3) which has free amine groups at the 3- and 5-positions in the triazole moiety with a carboxylic acid or a halide or anhydride thereof to obtain a mono-aryl derivative. Detailed examples are given and salts with mineral and sulphonic acids are referred to.  2-Hydrazino -5- bromopyrimidine is prepared by nitrating 2-amino-5-bromopyrimidine to obtain 2-nitroamino-5-bromopyrimidine and heating this with hydrazine hydrate. 2-Hydrazino-5-chloro-pyrimidine is prepared similarly via 2-nitroamino-5-chloro-pyrimidine.

Title: Spreader apparatus for tubular knitted fabrics
IPC: D06C5/00
Filed: 1973-06-11
Abstract: 1424451 Finishing and treating fabric SAMCOE HOLDING CORP 11 June 1973 27760/73 Headings D1L and D1S An internal spreader 86 for tubular knitted fabric comprises a plurality of_ segments located end-to-end defining the longitudinally extending sides of the spreader, the segments being composed of pairs of bars 90, 92 defining the sides and a plurality of braces 96 connecting the sides, the interconnection between each segment and an adjacent segment defining contact areas 94 for tubular fabric passing thereover, the areas 94 defining substantially the extent of distention of the fabric passing thereover.  In one embodiment, Fig. 2, the spreader 86 comprises criss-crosscd bars 90, 92 and the areas 94 being connected by braces 88. At each end, bars 91 are connected blocks 100 each having a pair of rollers 102 journalled therein. Telescopic cross-braces 96 and spacers 98 are adjustable for different diameter fabric tubes. A V-shaped fabric tube opener 104 extends from one pair of blocks 100. In another embodiment. Fig. 3, the spreader 106 comprises bars 135 arranged so that the contact areas 108 on one side thereof alternate with contact areas 110 on the other side thereof and the areas 108, 110 alternate with non- contact areas 114, 112, respectively. Vertical braces 111 and cross-braces 115 are provided. The spreader 86 or 106 is used in apparatus for heat treating or drying tubular knitted fabric, e.g. of wool, cotton, nylon or polyester fibres, into which apparatus the fabric passes from a stripe straightener 74, Fig. 1, between rollers 80, 82 and through a pre-heat treating zone 38, a heat treating zone 40, a post-heat treating zone 42, and a cooling device 116 whilst passing around the spreader. The arrangement is suoh that the fabric contacts areas of the spreader are not disposed within the zone 40. Sides rollers 84, 128 engage the spreader rollers 102. Air is heated by heaters 46, 48, e.g. direct flame gas or oil heaters, radiant heaters containing heat exchange tubes carrying hot water or steam, or electric heaters, and is forced by a blower 44 into a plenum chamber 47 and around oval brackets 66 defining orifices 68 through which it passes into the fabric. Live steam may be injected into the chamber 47. A portion of air is drawn by a fan 58 out through the top of an exhaust tower 64 and another portion is recirculated. The device 116 comprises a circular manifold 118 distributing cooling air to orifices 120. After being treated, the fabric may be longitudinally slit by a motor-driven circular cutting blade (128), Fig. 4 (not shown). A dancer tension roller (132) acts on the open-width fabric.

Title: Automatic control system
IPC: G05D1/08
Filed: 1945-10-22
Abstract: 611,226. Automatic control systems for aircraft. BENDIX AVIATION CORPORATION. Oct. 22, 1945, No. 27814. Convention date, Nov. 10, 1944. [Class 38 (iv)] Attitude, steering.-The control surface of a craft is actuated by a servomotor energized both by signals from a device responsive to variation of the craft from a desired course, and by follow-up signals, hunting being prevented by damping signals derived from the displacement signals after a time lag. If, e.g. the bearing of the craft alters, a displacement signal is produced in 11 proportional to the undesired displacement and applied to valve 14 feeding two valves 22, 23 in parallel to energize winding 42 of servomotor 43 in the appropriate direction to adjust the rudder 10 to bring the craft back to the desired bearing. The motor 43 also drives a rotor 52 to develop a voltage related to the rudder displacement which is applied over a bridge 90... 93 to valve 14 in opposition to the voltage from 11, so that the rudder is deflected until the signal from 52 is equal to that from 11. The signal from 11 decreases as the craft returns to the correct bearing, so that the signal from 52 causes the servomotor 42 to be energized in the reverse direction to restore the rudder to the normal position. Any prolonged tendency of the craft to change its bearing will thus produce hunting, which is eliminated by applying the signal from 11 to two valves 102 to produce current in heaters 98, 99 to vary the associated resistances 90, 91 to disturb the balance of the bridge and add a voltage from 94, 95 to valve 14 in opposition to that applied from rotor 52, so that continuous generation of a signal from 11 will result in the application of voltage in opposition to that fed back from 52 to valve 15 to maintain the rudder 10 away from the normal position. Specification 22906/44, as open to inspection under Sect. 91, is referred to.  The Specification as open to inspection under Sect. 91 includes a modification, Fig. 1 (Cancelled), in which the follow-up signals from 52 are amplified at 76 and applied to either heaters 70, 72 or 71, 73 to vary the resistances of the bridge 58 ... 61 and allow A.C. from 67 to be applied to valve 14 as a damping signal; the follow-up signal is applied over transformer 55, 56 direct to valve 14. This subject-matter does not appear in the Specification as accepted.

The reinforcement may be in the form of a cardboard disc inserted in the region of the bead 3 before introducing buffer layers of resilient material, e.g. felt. To weight the bullet, a lead disc may be placed against the buffer layers and the remaining space filled with a hardenable material, such as a casting resin, introduced through an opening (20), Fig. 9 (not shown), in the base. The reinforcement may also be in the form of a ring (21), Fig. 9, which may be placed on the plastics bag (14) before introduction into the casing 2. The base 6 may be held in the casing 1 by similar teeth or the base may have a groove 8 which snaps over a shoulder 9 of the casing. The base 6 may also be provided with intersecting reinforcement ribs. A viscous substance such as dioctyl phthalate may be mixed with the filling and a plastics tube (15), Fig. 3 (not shown), may be shrunk on to the casing 1.

Mixing fluids in flow. -In apparatus for cleaning tumblers, &c., of the type described in Specification 188.174, [Class 138 (i), Washing and cleaning buildings &c.], disinfectant is entrained with the cleansing water by the action of the water falling intermittently from a primary tank into which the water supply is led. Water is supplied to one of the compartments 26 of a tank through a valve 27 controlled by a float 28 in the receiver and flows over a baffle plate 29 into another compartment 30 and out through an outlet 31 into the receiver. In its fall it actuates a lever 34 to open a valve 32 whereby disinfectant in a third compartment 33 may escape into the receiver. When the liquid rises to a certain height in the receiver the float 28 is raised to stop the flow of water into the compartment 26, the flow recommencing when sufficient liquid has flowed from the receiver to the washing appliance of the apparatus.
