Title: Electric storage batteries
Inventor: CORBIN RALPH LEO
IPC: H01M50/147
Filed: 1970-09-10
Abstract: 1,262,239. Storage battery casings. GENERAL MOTORS CORP: 10 Sept., 1970 [12 Sept., 1969], No. 43406/70. Heading H1B. A storage battery casing 10 having partitions 18 forming cell compartments 22 is closed by a cover 14 provided with a plate-like filler cap 16 extending over the several ports 52 corresponding to the individual cells. The cover 14 has transverse grooves 20 on its underside receiving the partitions 18 and on its upperside, above the grooves 20, it has grooves 32 receiving transverse ribs 34 formed on the underside of the cap 16; also, longitudinal grooves 30 on the cover receive longitudinal ribs 34 on the cap. The cover 14 is sealed at 75 to the casing 10 and the cap 16 may be sealed to the cover by adhesive 74 in the grooves 30, 32. Above each compartment 22 a transverse vent chamber 36 is formed on the upperside of the cover 14, each chamber being defined by side walls 43 which also define a groove 32. The floor of each chamber is formed by a ramp 44 which slopes upwardly from a port 52 in an exponential curve. Thus, electrolyte which may enter a chamber 36 due to an abrupt motion of the battery will impinge on a baffle 68 on the underside of the cap 16 and drain back down the ramp 44 into the cell beneath. Tubular slush baffles 54 depending from the cap 16'through the ports 52 serve to restrict entry of electrolyte into the chambers 36 and facilitate return of the electrolyte to the cells. Gases may vent through the annular spaces 64 between the ports 52 and baffles 54 and reach a longitudinal-manifold 23 leading to-vent apertures 72 in the cover 14.

Patent GB-442547-A (GB)
Abstract: 442,547. Regulating combustion in furnaces. SCOTT, C. L., Leicester Arms Hotel, Penshurst, Kent. Aug. 10, 1934, No. 23168. [Class 51 (i)] A solid fuel fired furnace for domestic water heating and like purposes having an inclined main grate and a pilot grate at a lower level than the main grate so as to receive fuel therefrom, is provided with separate control of the primary air to two or more sections of the main grate so that the size of the fire may be controlled in sections to suit the demand for heat. In one construction Fig. 1, the pilot grate 4 is in the form of a rectangular trough with one side adjacent the foot of an inclined main grate. Air for combustion enters at A and passes under the control of a valve 10 to the space above the fire and to the ashpit 5. The air supply from the ashpit to the sections of the main grate is controlled by valves 9, 9a operated by a thermostat responsive to the temperature of the water in the jacket 15. The thermostat may also operate the valve 10. In a modification, Fig. 2, the primary air passes to the main grate sections through ducts 19, 19a controlled by a valve 10a carried by an extension of the spindle 10b of the valve 10. The pilot grate is part cylindrical and may be rotated about its axis 17 for the discharge of ash. In other modifications the pilot grate may form a third section of the grate and have a thermostatically controlled primary air supply ; the grate may be of conical form or of trough form with two inclined main grates. The outlet flue is preferably provided with a check-draught damper such as that described in Specification 440,796, [Group X]. Specification 442,580 also is referred to.
Patent GB-922418-A (GB)
Title: Improvements in or relating to equipment for bore-holes for short-firing and other purposes
Inventor: POTTER JOHN JAMES
IPC: E21C37/12
Filed: 1959-12-31
Abstract: 922,418. Fluid-pressure blasting devices. HAYDEN-NILOS Ltd. Dec. 29, 1960 [Dec. 31, 1959], No. 44353/59. Class 9 (1). An infusion equipment tube 1 is surrounded by a resilient tubular seal 2 constrained at its ends to the tube by shrouds 3 and 4, such that the full pressure of water supplied to the bore 8 is received by the seal through the transverse ports 7, while the outlet end of the bore 8 is closed by a spring-loaded reducing valve. The shrouds are formed integrally with inlet and outlet caps 5 and 6 respectively, which are counter-bored and tapped to screw on to threaded ends of the tube 1, while the main tube 9 is screwed on to inlet cap 5. The untapped portion of the outlet counter-bore 10 carries the headed stem of the valve seating member 14 whose compression spring 13 resides in the narrower counter-bore 12. The seating pad 15 of the valve member 14 beds on an annular seat 16 at the entrance to the bore 8. When the seal 2 is inflated by the water from tube 9 the increasing pressure opens the valve so that water may enter the counterbore 10 and pass into the shot hole through holes 17 until the pressure drop across the valve reaches the value at which it closes, said valve being determined by the stiffness of the spring 13. An alternative form of the invention has an outlet end cap counter-bored from its outer end leading inward to a narrower bore providing a seating for a ball valve which is held in position by a compressed spring retained by a union at the outer end of the counter-bore. The spring may be replaced or its loading altered by removing or adjusting the union, as the case may be; the water flow when the valve operates is here entirely through the counter-bore and union. Specification 853,272 is referred to.
Patent GB-938473-A (GB)
Title: Improvements in control adjustment mechanisms for condition-responsive control devices
IPC: G05G1/00
Filed: 1959-12-31
Abstract: 938,473. Fluid actuation of switches. MINNEAPOLIS - HONEYWELL REGULATOR CO. Dec. 31, 1959 [Dec. 31, 1958], No. 44422/59. Class 38 (5). In a condition-responsive control device comprising a condition-responsive element, a movable operating member which travels under the action of the condition-responsive element be tween two control points, a main control spring acting on the operating member throughout its travel and determining the force to be exerted on the operating member by the conditionresponsive element when one control point is reached, an auxiliary or pick-up spring acting on the operating member during only part of its travel whereby the two springs together determine the force at the other control point, separate control point setting means are provided for adjusting the force of each spring, and operative connections between the two control point setting means are such that operation of either control point setting means alone adjusts the respective control point without changing the other control point. In a pressure-responsive switch, increase in pressure moves a diaphragm 17 and hence the lever 22, pivoted in a plane parallel to the paper, which via an abutment screw 39 rotates a spring-loaded bellcrank lever 35 and this in turn through a lostmotion pin-and-slot connection tilts a mercury switch 26. As the lever 22 moves, it is first opposed by a main spring 42 but then moves a rod 58 and hence a second lever 55 so that subsequent movement is opposed also by an auxiliary pick-up spring 62. As pressure decreases, both levers 22, 55 move back under spring-pressure until the rod 58 strikes the switch casing 10, when only the lever 22 continues to move, sliding along a reduced end portion 59 of the rod 58. Thus the lower control point of the switch is determined only by the main spring 42, the upper point being determined by the additive effect of both main spring 42 and auxiliary pick-up spring 62. Adjustment of the lower control point is carried out by manually turning a knurled wheel ,47 to cause a nut 45 to slide along its threaded rod 46 and so alter the pressure of the main spring 42. Rotation of the nut 45 is prevented by an index finger attached thereto which engages a slot in a plate 51 fixed to the casing 10 and thereby also indicates the operative pressure of the lower control point. Rotation of the knurled wheel 47 also rotates a gear 65 which alters the auxiliary spring 62 in the opposite sense from the main spring 42, thus the upper control point is not altered. Adjustment of this upper control point is .effected by turning the second knurled wheel 67 to cause the gear 65 and its associated threaded nut to move along the threaded rod 66 and so adjust the pressure of the auxiliary spring 62 and move its indicating member 71 which engages a slot in the plate 51. No rotation of the gears 65, 48 occurs and hence no adjustment of the main spring.

Title: Nonwoven fabrics and methods of manufacturing the same
IPC: D04H1/66
Filed: 1960-12-30
Abstract: A bonded fibrous non woven textile fabric comprises a web of over-lapping intersecting cellulosic fibres and a formaldehyde cross-linked cellulosic binder distributed throughout the web uniformly or in a predetermined pattern of closely spaced binder segments, the formaldehyde content of the finished fabric being between 0.1% and 0.8% of the fabric.  When used in these proportions the formaldehyde is stated to have substantially no binding effect on the fibres themselves.  Specified fibres are rayon and cotton.  The web may be formed by carding, air-laying or water-laying.  Specified cellulosic binders are cellulose regenerated from viscose, cuprammonium solutions, alkyl ethers and esters of cellulose, e.g. methyl, ethyl or propyl ethers and carboxy-methyl and hydroxyethyl ethers of cellulose, and chitin. Suitable formaldehyde cross-linking compounds are formaldehyde itself, compounds which decompose to liberate formaldehyde, or resins which contain formaldehyde in a reactive form; e.g. water soluble precondensates or low polymers of methylolurea or methylolmelamine.  The action of the cross-linking agent on the binder may be catalysed by common mineral acids or substances which become acids at elevated temperatures e.g. sulphuric, tartaric, lactic, boric, oxalic, acetic, formic and various sulphonic acids, ammonium thiocyanate, ammonium acid phosphate, ammonium chloride, magnesium chloride.  The catalyst is preferably used in concentration such that the pH of the fabric is not reduced by more than 0.5.  The spaced binder segments preferably cover 12-25% of the surface of the fabric.  Patterns of binder forming spaced straight or undulating lines or circular or square areas are described.  In a further modification parallel lines of binder are applied on opposite sides of the fabric and mutually at right angles, the binder in the individual lines penetrating only half way through the fabric.  Specifications 468,529, 674,779, 677,928, 833,697 and 836,397 are referred to.
