Title: Improvements in and relating to Signalling Appliances for Collieries and the like.
Inventor: NEIL JAMES
IPC: B66B19/06
Filed: 1915-10-07
Abstract: 101,755. Neil, J. Oct. 7, 191 Mechanical telegraphs ; mine and colliery signals.-Relates to cancelling-means for colliery and the like signalling-appliances such as are described in Specification 14193/15. Two types of device are set forth, one for cancelling one signal, and the other for cancelling two signals in succession. Various modifications of the first type are described, all governorball actuated. Fig. 1 shows a trip roller 12 drawn along by the governor sleeve 2 to engage a similar roller 12 on a lever 8 connected at each end by chains 10 to a rod 11 joined by flexible connexions to the indicator mechanism. Thus, on the starting and stopping of the engine, the lever 8 is actuated and the rod 11 pulled to cancel each signal made. Fig. 3 shows a form in which a clutch disk 16 at first turns a loose disk 15 and so cancels the signal by a flexible connexion to a projection 14, the disk 16 then leaving the disk 15 and running free until the engine slows down, when the disks again contact and the signal is cancelled. To ensure that the disks shall remain in contact with one an. other for a sufficient interval, they may be arranged horizontally so that the disk 15 falls with the disk 16 till stopped by a collar on the vertical shaft 4. Fig. 6 shows a form in which a projection 17 on the rotating disk 16 contacts with a roller on the end of a lever 18 at the beginning and end of the wind. In Fig. 8, the disk 16 is shown with two notches 19 which engage a spring plunger pin 20 carried by a counterweighted lever 21 pivoted at 22 to a bracket 23 loosely mounted on the shaft 4. A spring-controlled lever 25, with a fork 27 embracing a neck 28 on the bracket 23, is attached at its other end to the signaling-connexion to ensure that the pin 20 will be in proper position before the start of a wind. Fig. 10 shows a device of the second type. The initial and final rotation of the shaft 34 causes a tooth 37 to strike a tooth 40 and oscillate a counterweighted cross-lever 38, which has its ends joined by flexible connexions to a slidable block 42 connected to the indicator. As the engine gains speed, governor blocks 3 fly outwards against the action of springs 31 and draw the shaft 34 along till a collar 52 thereon strikes against a roller 51 on a lever 46, so pulling a slidable block 50 and cancelling the " men " signal.

Title: Respiratory apparatus
IPC: A62B9/02
Filed: 1948-02-05
Abstract: 640,316. Respiratory appliances. MANDET, Y. J. B. Feb. 5, 1948, No. 3389. Convention date, Nov. 27, 1947. [Class 81(ii)] [Also in Group XXIX] Between the high pressure air or gas supply of a respiratory appliance and the mask is placed a pressure regulator comprising two stages in series, one reducing the pressure to slightly greater than atmospheric and the other supplying respiratory air at a pressure equal to the surrounding atmosphere. In the first stage a loading spring 9 adjusted by a screwed cap 22 and pressing on a relatively small diaphragm 6 acts through a bell crank 7 and pin 26 to tend to lift a valve 5 off its seating, against a returning spring 5a. The size of the diaphragm 6 and the loading of the spring 9 are such that the pressure in the chamber 2 is slightly above atmospheric. The second chamber 3 communicates with the face mask through a hose connection 16 and has one wall formed by a diaphragm 11 open to atmospheric pressure on its outer face. When the wearer breathes in the rarefaction in this chamber causes the diaphragm to bow inwards and depress the lever 13, with the result that an arm on a pivot 14 actuating a pin 27, lifts the secondary valve 15 off its seating to allow air to pass to chamber 3. Immediately the pressure in this chamber rises to atmospheric the valve again closes. To overcome losses in the outlet pipe a light spring may press on the outer face of diaphragm 11.

Patent GB-1121452-A (GB)
Title: Improvements in or relating to thermo-luminescent dosimeters
IPC: G01T1/11
Filed: 1966-01-26
Abstract: A thermoluminescent dosimeter for ionizing radiation comprises first and second parts of an active thermoluminescent substance arranged side-by-side on the surface of a support, said support being provided within a container transparent to said radiation and with a heater for raising the temperature of the first part at a rate different from that of the second part.  This different rate of heating may be achieved in various ways:-Fig. 1 shows the support 1 as a tube containing a helically wound heater filament 3 with an axis coincident with that of the support, the pitches of those parts of the helix adjacent said first and second parts being different; alternatively as shown in Fig. 2, the pitch of the helix may be the same throughout the length of the support 1 being arranged to supply substantially identical quantities of heat to the two parts in identical periods of time but the wall thickness of the tube 1 is different at the two parts 7 and 8; in Figs. 3 and 4 on the other hand, the heat supplied is again the same but in the first the layers 7 and 8 have different thicknesses and in the second a sleeve of heat resistant insulation material 11 is provided between the support 1 and one of the layers.  In a preferred embodiment, Fig. 5, the support 1 is constituted by two sections 13, 14, joined by spot weld 12. Section 13 has a linearly increasing thickness from the free end towards the junction with 14, and is coated with a layer 8 of thermoluminescent material which also increases in thickness as it approaches section 14.  Section 14 is a tube of constant and thinner thickness than 13 and supports luminescent layer 7.  The advantage of the above arrangement is that the thicker section of the section 13 allows for the heat conducted from section 14 and thus layer 8 exhibits an even temperature over its whole length, furthermore, a delay of luminescence between sections 7 and 8 may be obtained.  The luminescence may be recorded photographically or with an oscilloscope to determine the radiation dose received by the dosimeter.  The two different sections of the dosimeter may be used to record different doses, e.g. current and cumulative radiation dose.  The container of the dosimeter may be evacuated, or a very low gas pressure may prevail therein.
