A machine for grinding the edges of panels 19 of glass or the like comprises one or more conveyer belts 22a, 22b for displacing the panels and several grinding devices each of which has a grinding wheel 36 shaped for grinding the edges of the panels, all the grinding devices being adapted to be pivoted simultaneously into an inclined position by an adjusting device. The machine has side plates 11, 13 between which extend a pair of support axles 14, 15. Rails 17, 18 are disposed adjacent side plates 11, 12 and carries rollers about which the conveyer belts 22a, 22b are entrained, rail 18 being supported by a bracket 16 adjustably mounted on the axles 14, 15 whereby the distance apart of the belts can be adjusted to accommodate different sizes of panels. Pressure rollers 27a, 27b are carried by beams 26a, 26b above the conveyer belts. The panels are guided laterally by vertically arranged rollers 25 adjacent a roller belt 24 arranged at the inserting side of the machine, the ground panel being conveyed from the machine on rollers 57. The side plate 11 has a pair of pivots 30 for the grinding devices 28a, 28b for operating on one edge of the glass panel, each device consisting of a driving device 31 which is vertically-adjustably carried by a bearing 33 on the pivot and drives a grinding wheel 36 having a profile 32 which may be semicircular, or in the form of a truncated core. The grinding devices 29a for the other edge of the glass panel are similarly mounted on pivots 30 on the bracket 16, the pivots being coaxial with those for the devices 28a, 28b. Each pivot 30 carries a toothed segment 41, 48, 52 engaging a respective pinion 40, 47, 50 on a pair of shafts 38, 46 located in bearings in the side plates 11, 13 the two shafts being interconnected by cranks 43a, 45a and a link 44 for rotational adjustment in unison by a hand lever 39 on the shaft 38 whereby the grinding devices are simultaneously adjusted. A stop finger 54 on the hand lever can be selectively engaged with a recess 55 in a member 56 to releasably retain the grinding devices in their adjusted position. With the grinding devices in the vertical position, the grinding wheels form a rounded edge on glass of a predetermined maximum thickness. For glass of less thickness than the maximum, the devices are inclined an appropriate amount so that the planes of the grinding wheels are inclined to the plane of the glass as illustrated in Figs. 4 and 6 (not shown). The devices can be vertically adjusted so that only one side of the edges are ground.

Title: Improvements in or relating to the continuous heat treatment of sheet or strip material
Inventor: AYERS PETER
IPC: C21D9/567
Filed: 1962-05-23
Abstract: <PICT:1049362/C6-C7/1> A method and apparatus for continuously heat treating strip material comprise passing the strip in succession through two fluidized beds at different temperatures, and maintaining the strip with its faces in substantially vertical planes during its passage through the beds.  In the form shown the strip 25 is passed consecutively through first and second fluidized beds 2, 3 respectively and hence through a chamber 20.  The first bed 2, contains heaters 11, arranged in such manner as to direct the fluidized material against the said strip, and maintaining the first bed at a temperature higher than that of the second, which is provided with a cooling pipe 13 and baffles 12 to direct the fluidizable material therein against the strip. The strip enters and leaves successive chambers through slits 14, 5, 18, 14a in the respective walls thereof, the slits being defined by a resilient material, (Figs. 3-5, not shown).  Passage of fluidized particles through the slit 18 is minimized by maintaining the chamber 20 at a pressure above that of the chamber 3; any particles passing therethrough being returned to the chamber 3 via the pipe 21 and cyclone separator 22.  The baths are fluidized by means of air supplied under pressure through pipes 9, 10 to plenum chambers 7, 8 and hence through the wire mesh 6 to chambers 2, 3 respectively. In a further embodiment (Fig. 6, 7, not shown) the first and second chambers containing fluidizing material are formed with a slot in the floor of each, which slots are connected by an intermediate chamber defined by two spaced curvilinear walls.  The strip material passes vertically downwards through the first chamber, through the curvilinear intermediate chamber, protected from contact therewith by an air cushion, and vertically upwards through the second chamber. Examples are given of the effect of such heat treatment on aluminium alloy strip.

Filed: 1921-07-25
Abstract: 178,039. Feeny, V. r., (Hardy, Geb.). July 25, 1921. Fluid-pressure.- In pneumatic pressure and vacuum brakes, a valve is fitted to cut off the connection between the auxiliary reservoir and the brake cylinder when the hand release valve is actuated. As described in connection with a vacuum brake, a lift valve 7 controls the connection between pipes 4, 5, 6, leading respectively to the hand-actuated brake-release valve, the auxiliary reservoir, and the brake cylinder. When the brake is applied, the pressures in the pipes 4, 5, 6 are equal, the pressure in the pipe 4 being equalized through an opening 8 in the valve 7. When the brakes are released by a change of pressure in the train pipe and the pipe 6, the valve remains unmoved. When both cylinder chambers and also the pipe 4 are opened to the atmosphere by the release valve, the valve 7 is thrown from the seat 2 to the seat 3, and cuts off the auxiliary-reservoir connection 5 from the pipes 4, 6. When the release valve is closed. and connection is again established between the brake cylinder and train pipe, and the brakes are released by a reduction of pressure thereinthe valve 7 then falls to its seat 2. In air-pressure brakes the arrangement of the seats 2, 3, 4 reversed.

Title: Improvements in circuit-arrangements for use in telephone exchanges
IPC: H04M19/02
Filed: 1958-06-26
Abstract: 830,330. Automatic exchange apparatus. PHILIPS ELECTRICAL INDUSTRIES Ltd. June 26, 1958, No. 20537/58. Class 40 (4). In a telephone system in which final connection to a wanted subscriber is made by the breaking down of a cold cathode tube, an electrode of this tube other than its anode or cathode provides a control voltage to condition a further cold cathode tube to conduct and connect ringing to the wanted subscriber provided his loop circuit is broken. As illustrated, a subscriber S1 breaks down a cold cathode tube T1 in initiating a call and over a register CR causes the breakdown of the particular tube T2 in the circuit of the wanted subscriber S2. An electrode of tube T2 is connected to earth over rectifier 12 and to one end of a potential divider 9, 10 connected at its other end to a multivibrator Q which alternates earth for one second with - 60 volts for five seconds. A 50 cycle source of ringing current is coupled to the anode of a tube V2 over transformer RT and, providing V2 is triggered to conduct, energizes the transformer 2 of the wanted subscriber. The cathode of V2 is connected to point 8 of transformer 2 which is at - 60 volts when the subscriber's loop is broken but becomes - 30 volts as soon as the loop is made. The electrode of T2 connected to the resistors 9 and 10 has a potential at earth when T2 is not conducting and a potential of 70 volts when it does conduct: and this increased voltage causes the junction between 9 and 10. connected to the trigger of V2, to alternate between 30 volts and earth whereas it normally alternates between earth and - 30 volts. Tube V2 can strike only when T2 conducts and the point 8 of transformer 2 is at - 60 volts, and during this' time a voltage in excess of the 70 volts required to ignite the tube is put across cathode and trigger electrode every time multivibrator Q connects earth for one second every sixth second. As soon as the subscriber's loop is made, point 8 falls to - 30 volts and ringing is disconnected as V2 can no longer fire.
