Title: Life indicator for primary zinc batteries
IPC: H01M6/50
Filed: 1973-07-16
Abstract: 1387560 Zinc primary cell CARBONE CORP 16 July 1973 33720/73 Heading H1B A zinc electrode 14 immersed in an electrolyte 12 is provided at three locations 17 with means that indicate that the electrode has been consumed to a certain extent and will shortly need to be replaced. Each indicator comprises a recess 9 in the electrode extending a certain depth so that a desired thickness of zinc overlies the end of the recess, the recess receiving a dye 18 in liquid or powder form and aluminium powder 20 and being closed by an inert plug 31, e.g. of pitch. When the zinc is consumed to expose the recess 9 the dye 18 is released into the electrolyte and the aluminium powder 20 reacts vigorously with the electrolyte to ensure that the dye adequately mixes to discolour the electrolyte. The electrolyte is observed by removing a cap 11. In another embodiment (Fig. 5, not shown), the aluminium powder is replaced by NaOH or KOH in powder form and this powder together with the dye powder is ejected by a spring contained in the recess 9 when the zinc closing the end of the recess has been consumed. When the electrolyte is KOH a suitable dye is tropaelin-0 or fluorescein.

Furring strips 60, Fig. 6, for linings are attached to the wall by pins 41 having the head embedded in the wall and which pass through the strips and have the ends bent over into a groove 61 in the furring strips. The pins 41 are initially carried in holes in the sections. 26 in which they are held by hairpin tie members. The studs may be formed as shown of channel sections back to back with distance pieces to provide a space for tie bars 30. Forms for casting corners are shown. In one method the forms are arranged_ at right angles to an already cast wall. In another the forms are arranged at right angles and the corner cast as an integral unit, the outer forms being held in position by an external right angle structure or by being bolted together. An expansion joint 115, Fig. 13, may be arranged between the two wall parts of a corner, held in place by a male key 114 in one part passing through the joint and engaging in a female key 113 in the other part.

Abstract: 958,052. Typewriters. SPERRY RAND CORPORATION. Sept. 27,1961, No. 34664/61. Heading B6F. Line-spacing mechanism.-A line-spacing mechanism is detachably and entirely mounted on a support plate 20, Fig. 2, attached to a side frame 13(Fig. 1, not shown) and carries an actuating slide 30, connected at its upper end to an upper pin 32 slidable in a slot 34 and at its lower end to an actuating arm 26 by a lower pin 31 slidable in a slot 33 of the support plate 20. A pawl 35 having a tooth 36 and a bearing arm 37 is pivotally mounted on the slide 30 by the upper pin 32. The pawl is held normally out of engagement with the ratchet-wheel 15, whose teeth arrangement corresponds to that of singleline spacing, by the bearing arm 37, which presses against a resilient adjusting arm 39. The arm 39 has line-spacing notches 44, 45 and 46 co-operating with an adjusting lever 40, a stop on which limits the upward movement of the adjusting arm 39. On each carriage return the actuating arm 26 is pulled against the resistance of a spring 29 by a tape 25 to move the slide 30 downwards, whereupon the spring 38 in the pawl urges the pawl tooth 36 into contact with one of the ratchet-wheel teeth and continued downward movement of the slide 30 produces rotation of the platen 11 by the number of line spaces preselected by the lever 40. The line increment movement is stopped by the engagement of the pawl tooth 36 with a stop 55. A detent release arm 51 pivotally mounted at 52 has a portion 53 provided with notches 56, 57, the notch 56 holding a roller 48 mounted on a spring-urged detent lever 49 out of engagement with the ratchetwheel teeth for free rotation of the platen. U.S.A. Specification 2,874,369 is referred to.

Abstract: An insecticidal composition comprising a homogeneous mixture of 1,1,1 trichloro 2,2 di-p-chlorophenyl ethane (D.D.T.) and benzene hexachloride (B.H.C.) preferably in the form of Lindane in which the B.H.C. is present in the proportion of 10 to 80% by weight of the combined weight of the B.H.C. and D.D.T. so that the temperature at which the composition melts is reduced to that at which a continuous flow aerosol is produced by vaporization from the melted mixture which aerosol has an enhanced insecticidal effect without any substantial decomposition of either ingredient. A small amount of a decomposition inhibitor e.g. a lubricating oil preferably in an amount of 2% by weight of the mixture may also be included.  A surface may be provided with a deposit having insecticidal properties by exposing it in an enclosed space to an aerosol formed by maintaining compositions at a predetermined temperature between 75 and 135 DEG C. depending upon the volume of the enclosed space and the proportion of benzene hexachloride in the mixture so as not to exceed an output of 27 milligrams per hour per 1000 cubic feet.

[Class 108 (iii)] [Also in Group XXIV] In a torsion spring device comprising rubber and metal parts connected by adhesion or vulcanization, one metal hub-part 1 adapted to be secured to a member subjected to torsional oscillations, is formed with a wave-shaped profile in cross-section and is partly enclosed by the bellshaped cross-section profile of the other metal casing-part 3 so that the rubber 5 separating the parts may have large torsional displacements whereas the possible radial and axial displacements are small. As shown, the casing 3 is in two parts having flanges 4 by which the device is secured to a support, frame, foundation, &c. A plurality of such spring devices may be arranged coaxially all the casings and all the hubs being connected together, or the casing of the first device may be connected with the hub of the second device and so on. In the former case the connected hubs may take the form of a screw-thread and the casing shaped to conform therewith, relative rotatable movements of the two parts being limited by axial compression of the rubber.

The attenuator includes a second electronic impedance connected to the junction of the series resistors and shunting one of them, the output being derived from the other resistor. As shown, the input to a signal attenuator is applied to the grid of a valve T1, having a cathode resistor R1. The cathode of T1 is connected through a resistance R3 to the cathode of a second valve T2, having a cathode resistor R2. The grid of valve T2 is earthed, and the output is taken from a tap on R3. By adjusting R2, equal D.C. potentials may be obtained at the ends of R3. A common anode supply is provided for T1, and T2, which may be separate valves, or the sections of a double triode, For use with an oscilloscope, the attenuator may be fed from a resistancecapacity step attenuator (Fig. 4, not shown), the output being fed through a cathode-coupled phase-inverter to a push-pull amplifier connected to the deflection plates.
