Abstract: 1492032 Metal-air batteries LUCAS BATTERIES Ltd 11 April 1975 [18 April 1974] 16897/74 Heading H1B A metal-air battery comprises a group of cells 16 in a casing 11, each cell including a pair of air electrodes 18 and a metal anode 25 mounted in a space defined by a framework 17, the frameworks defining a filling channel 38 and being provided with apertures 30 whereby to activate the battery, liquid for producing the electrolyte can be introduced into each space via the filling channel and the apertures. The frameworks 17 are made of A.B.S. polypropylene or nylon and are pressed into an expanded nickel mesh 21 of the air electrodes. The mesh 21 supports a sheet 19 of porous P.T.F.E. and a layer 22 of catalyst material such as carbon, silver/carbon or platinum/carbon mixture, the air electrodes being formed by hot pressing. Each anode 25 consists of a copper grid supporting compressed zinc which is electro-formed from zinc oxide, the anodes being wrapped with porous sheets 26 of polyamide material. An electrolyte wafer 29 formed by compressing a mixture of KOH flakes, aqueous KOH solution and carboxy methyl cellulose is positioned at the top of each cell. Rubber gaskets (not shown) coated with adhesive seal the cells together and to the casing which is provided with air vents 15. During storage the channel 38 is sealed by a piece of card with a wedge of sponge under a temporary retaining plate. To activate the battery, the card and sponge rubber are removed and water is poured into the channel 28, the battery then being layed on one side 14 to equalize the electrolyte levels in the cells and dissolve the wafers 29. The battery is then positioned upright and the temporary retaining plate is removed before insertion of a rubber strip 42 bonded to a silicone coated strip 43.

Title: Improvements in or relating to combined edge gumming and perforating machines for manufacturing memorandum and like pads
IPC: B42C9/00
Filed: 1945-07-03
Abstract: A machine for producing memorandum and like pads wherein the paper sheets are fed singly and superposed on a table, each sheet having a strip of gum applied thereto by a gumming blade and, when the pad is complete, the table is moved to feed the pad to perforating rollers, the gumming blade 7, Fig. 5, is carried by trunnions rotatable in a pair of arms 45 on a shaft 46 oscillated by a pinion 47 which is driven by a sector gear oscillated by a crank lever (see Group XV). One trunnion has fixed thereto a gear 62 engaging an idler gear 61 on the corresponding arm 45, the gear 61 meshing with a gear 59 fixed to the frame of the machine so that, as the arms 45 are rocked, the blade remains vertical as it moves to and from a gum-supply roller and the sheets.  In certain kinds of pads the top sheet is narrower than the others and therefore the top sheet but one is gummed over part of its width only.  To <PICT:0596414/III/1> <PICT:0596414/III/2> effect this, the blade 7 may be secured to a shaft 69, Fig. 6, to which a shorter gumming blade 70 is secured and the gear 59, instead of being fixed to the frame, is carried by a lever 72 connected to and moved by a pedal, depression of which rotates the shaft 69 and carries the blade 70 into the vertical position.  In a modification wherein a wider blade is used, a lever similar to the lever 72 is spring-urged into contact with a cam which is so shaped that when the gumming blade is in contact with the gumming roller, the lever and thereby the gumming blade are oscillated so that the whole area of the blade contacts the gumming roller.

Title: Manufacture of printed circuit boards
IPC: H05K3/40
Filed: 1971-05-26
Abstract: 1326285 Coating with metals KOLLMORGEN CORP 26 May 1971 [26 May 1970] 17111/71 Heading C7F [Also in Division H1] Through holes of a printed circuit board 8 are uniformly coated with a conductive material and excess conductive material removed from the holes by gyrating the board while the conductive material is in at least its plastic state. The board is horizontally mounted in a frame 11 which is flexibly supported above a heated bath 12 containing, for example, wax. The bath is then raised by jack members (14) Fig.1 (not shown) till the frame and board are immersed in the bath and the conductive material is heated to at least its plastic state. Drivers 16 are then sequentially pulsed by oscillators 17 and 18, operating 90 degrees out of phase, resulting in a gyrating motion of the frame and board about a vertical axis and causing the conductive material in the through holes to flow circumferentially and axially out of the holes. The process is continued till the holes are uniformly coated and then, while continuing the gyrating motion, the frame and board are removed from the bath by lowering the jacks (14). When the conductive material has cooled and hardened the motion is stopped. Any excess conductive material which has flowed out of the holes and on to the surface of the board may then be removed by brushing, washing &c. Drivers 16 may be of the electrical, pneumatic or hydraulic type.

Title: Location of short circuits
Inventor: DAVIE OWEN HOSMER
IPC: G01R31/28
Filed: 1968-04-10
Abstract: 1,201,679. Locating short circuits. BRITISH COMMUNICATIONS CORP. Ltd. March 26, 1969 [April 10, 1968], No.17365/68. Heading G1U. To locate a short circuit in a network, current is caused to flow via the short between two first points in the network between which there is normally a relatively high impedance and the presence or absence of a consequential potential difference between two second points spaced along a network conductor is detected to determine whether the route of the short circuit current includes the portion of the conductor between the second points, these steps being repeated with the position of at least one of the second points adjusted to enable the position of the short circuit to be located. One second point and one first point may be common. The method may be used to locate a faulty module e.g. 3 in an integrated circuit assembly, consisting of a number of modules connected between two lines 1 and 4. Potential is applied between the lines from a supply 6 via a probe 7 also connected to the zero input of a differential amplifier 10. Probes 8 and 9 are located one to each side of the input probe 7 and are connected to the differential inputs of the amplifier. Current flow through the short circuit causes a potential difference between either probe 8 or 9 and probe 7 according to the location of the short circuit, to produce a deflection on the centre zero instrument 11 in a direction corresponding to the direction of flow. The position of the arrangement of probes is adjusted along the line 4 until this direction alters, the location of the fault thereby being established. In an alternative system Fig. 3 (not shown) where only limited access to the system under test is possible, the probe 7 and one of the others e.g. 9 are located at fixed positions at opposite ends of the line 4. The probe 8 is first connected to an access point close to the probe 7 and gradually moved along the line 4. When it reaches a position beyond which no short circuit current is flowing in the part of the line between the probes 8 and 9, no deflection is registered on the meter 11 (which in this arrangement need not be centre zero). Thus the location of the fault is determined.
