Filed: 1970-09-30
Abstract: 1335682 Light-sensitive material SHIPLEY CO Inc 30 Sept 1970 [29 Oct 1969] 46542/70 Heading G2C [Also in Division B5] A light-sensitive material comprises in order (1) a permeable backing layer, (2) an intermediate layer and (3) a non-silver salt-sensitized synthetic polymer based photo-resist layer; layer (2) is soluble or degradable in water or the developer for layer (3), while layer (1) is substantially insoluble in said water or developer. In use the material is laminated, preferably using a heat- and/or - pressure sensitive adhesive, to another substrate and then treated with water or developer to remove layer (2), and the backing layer (1) stripped off leaving layer (3) on the substrate. Preferably (1) is paper, (2) a colloid or polymer (e.g. vinyl methyl ether/ maleic anhydride copolymer) and (3) is a mixture of phenol- HCHO novolak resin and o-quinone diazide), the adhesive layer contains a small amount of photo-resist and optionally a cleaning agent for the substrate (e.g. is a mixture of o-quinone diazide an epoxy novolak resin and an acrylic or methacrylic acid copolymer), and the substrate is a copper clad or unclad circuit board. The backing and intermediate layers may be removed before exposure or during development.

Title: Improvements relating to the Charging of Storage Batteries
Inventor: RICE DAVID JOHN
IPC: H02J7/00
Filed: 1967-10-17
Abstract: 1,193,847. Battery charging circuits. CATYLATORS Ltd. 9 Oct., 1968 [17 Oct., 1967], No. 47302/67. Heading H2H. The charging of a storage battery is controlled in dependence on both the charge in the battery and the battery temperature. In the circuit shown, two Zener diodes Z1, Z2 are arranged to be equally affected by temperature changes in the battery, but Z1 is also exposed to any gassing from the battery. A thermistor TH is similarly exposed to the battery temperature. In operation, a D.C. source connected to terminals 1 charges a battery connected to terminals 2 through a transistor VT. A diode D is blocked. When gassing occurs in the battery, the hydrogen produced cools the Zener diode Z1 and the transistor VT is partially blocked due to the resultant fall in the potential of its base. If the battery temperature reaches a pre-determined value, the decrease in resistance of the thermistor causes the diode D to conduct and so turn off the transistor VT. In a modification, Fig. 2 (not shown), the diode is replaced by a second transistor, and a further thermistor is also included in the circuit.

Abstract: 1,019,802. Valves. PARKER-HANNIFIN CORPORATION. Dec. 18, 1962 [Dec. 20, 1961], No. 47740/62. Heading F2V. [Also in Division H1] A solenoid-actuated pilot-valve 1 has a twopart casing 2, 3 secured to block 4 housing a main valve, not shown. The part 3 incorporates a moulded elastomeric receptacle 12 with metal contact sleeves 14 therein to which are connected the supply leads 11; the part 3 embodies both a seat 16, with a passage 17 leading to a supply passage 6, and a passage 18 for fluid actuation of the spring-loaded main valve. The solenoid coil 22 is wound on a nylon bobbin, the lower flange 25 of which has an extension 27 housing contact pins 28 that cooperate with the sleeves 14; the flanges also embody concentric sawtooth serrations 32 that act as keys for a nylon shell 34 moulded around the bobbin 23 and extension 27 whereby the pins 28 and solenoid heads 31 are anchored. The shell around the extension is ribbed to permit the pins 28 to be close to but insulated from each other. The interior of the bobbin 23 is provided with three guide lands 36 for the armature 21, two of the lands having armature retaining hubs 37 whilst fluid passages around the armature are formed by enlargements or grooves between the lands 36. The casing part 2 includes an axiallymovable seat 41 mounted on a resilient ring 42 and inserted into the upper end of the bobbin, the seat including a shading ring 47. A flux sleeve 48 around the solenoid sits on a non-circular flux plate 50 which is sealed to but spaced from the flange 25 by a resilient ring 51 which also acts as a spring to keep the coil 22 against a flange of the seat 41 and avoids the necessity for close control of the lengths of the coil and flux sleeve; a similar purpose is served by the ring 42. A passage 59 through the seat 41 leads to an exhaust passage 5 in the block 4; the functions of passages 6 and 8 may be interchanged in which case the seat 41 is urged downwardly by fluid pressure, a lighter armature spring is used and the angle of the lower seat ring is altered. The armature 21 has resilient inserts 53, the upper one of which engages with a seat rib 46 before metal-to-metal contact between the armature and seat is established. The inserts are bonded in place but the outer portions are left free to move.

Abstract: 1,205,960. Valves. A. G. WILD & CO., Ltd. 24 Oct., 1968 [27 Oct., 1967], No. 48958/67. Heading F2V. A valve block controlling a mine roof support having a pair of props and an advancing ram is provided with two pairs of valve members, each arranged as in Fig. 4 for controlling a respective end of the ram, and a further two pairs of valve members each arranged as in Fig. 5 for controlling a respective one of the props. In Fig. 4, rotation of lever 23 cams a loose thrust plate 24 and the spring loading of inlet valve 3 and exhaust valve 4 is such that the plate 24 initially seats the valve 4 and then pivots about the end of the latter to unseat valve 3. A flat 28 on the lever 23 enables the latter to remain in its actuated position. In Fig. 5, both the inlet and exhaust valves are biased to closed positions. Clockwise rotation of lever 30 unseats valve 3 but the lever cannot reach a dead-centre position. Anti-clockwise rotation of lever 30 is transmitted by arm 35 to unseat valve 4. Co-operating flats 36, 37 allow the lever to remain set in this position. The exhaust valves controlling the ram may selectively discharge into the same or a different line to the exhaust valves controlling the props. Some of the inlet valves may have a separate supply line. Check valves 39, 40 allow connection of pressure gauges. In Fig. 1 (not shown), inlet and exhaust valves (3, 4) are biased to closed and open positions respectively, and are actuated by a rotary face cam (16). The exhaust valve seat is yieldable against a spring (14).
