Patent GB-127791-A (GB)
Title: Improvements relating to Fountain Pens.
Inventor: KEERAN CHARLES ROOD
IPC: B43K23/12
Filed: 1919-02-21
Abstract: 127,791. Keeran, C. R. Feb. 21, 1919. Reservoir pens. - An ink-tight joint between a pen section and a thin metal barrel is obtained by means of a bushing or the like of hard rubber or its equivalent, which is tightly or substantially permanently fitted to the barrel and is less tightly and removably fitted to the pen section. In the construction shown in Fig. 1, the barrel 5 is threaded internally and externally at the open end 7 to receive respectively a bushing 8 and the usual cap 11. The threads are in staggered relation to preserve a substantially uniform thickness of wall. The bushing 8 is threaded internally to receive the usual threaded stem 10 of the pen section, and fits sufficiently tightly in the thread of the barrel to prevent it from unscrewing when the pen section is being removed. The bussing may be flush with the end of the barrel, as shown, or may project beyond the end of the barrel. In the modification shown in Fig. 3, the bushing 23 has a drive or friction fit in the barrel 21. Longitudinal movement, of the bushing may be prevented by means of a shoulder 22 on the barrel, and by turning over the end 25 of the barrel. Rotation of the bushing may be prevented by means of projections 24 on the barrel engaging with the inner end of the bushing.

Title: Method and apparatus for destroying limited groups of cells
IPC: G01P15/12
Filed: 1963-02-04
Abstract: 998,173. Surgical destruction of cells. G. A. D. GORDON. Oct. 23, 1963 [Feb. 4, 1963]; No. 4465/63. Heading A5R. Apparatus for destroying tissue or cells by means of ultrasonic waves has means for radiating low power pulses for the location and identification of the target area, by an echosounding principle, after which waves at full power are radiated to carry out the treatment. The equipment described comprises a crystal 5 of concave shape, so as to direct its output to a focus 25, and it is mounted in a chamber 1 carried on a support 4. A damping element 13 may be lowered into engagement with the rear surface of the crystal by partial rotation of a quick-thread screw 16. A flexible container 19 is sewn or adhered to the prepared aperture 24 in the patient's skull 22 and is filled with saline solution which is circulated by a pump 27 through tubes 26, 29 and a heat exchanger 28 to ensure the maintenance of the correct temperature.  The upper silvered surface of the crystal is preferably divided into two large and two small sectors, so that for locating and investigating the desired area the large sectors may be used as a transmitter while the small ones serve as a receiver. During this operation the crystal is connected to a type of echo-sounding equipment and power is transmitted as series of short controlled pulses. It is, therefore, necessary for the damping element 13 to engage the crystal to prevent free oscillation and the control lever 17, associated with the element 13, is therefore linked to the switch 10 which effects changeover of the connections of the crystal from the echo-sounding equipment to the power oscillator equipment. In the latter setting the larger segments of the crystal may be used for transmitting power while the narrow segments are employed for monitoring. In this setting also, the damper 13 is raised so as to allow free oscillation of the crystal.  The radiating assembly, carried on the plate 4 is supported on a form of stereotactic mounting which enables the radiating axis of the crystal to be adjusted angularly about two axes at right angles to each other and also enables the whole assembly to be moved linearly about three mutually perpendicular axes.  In a modified form of the apparatus, intended for use on the eye, the crystal is of annular shape so that an ophthalmoscope may be directed through the central aperture to observe the site of the treatment visually.  Specification 990,702 is referred to.

Figs. 13-15 (not shown) illustrate stiffening means in the form of a helix 57 of wire which may have a rectangular or circular cross-section. The material surrounding the lamellae may be of greater rigidity than that of the main body of the cushion 5 as in Fig. 7 (not shown) where 34 is the common face between the two. Fig. 8 shows an embodiment where the cover 32 rests on a slide plate 35, of, for example P.T.F.E. Suitable materials for the lamellae or the helix are quoted as steel, brass, bronze or synthetic plastics material, for example polyamides or polyacetates. Suitable dimensions for the helix are given as a rectangular section 4 mm. by 1 mm. with 0À3 mm. spacing between turns.

Title: Improvements in the manufacture of peat fuel
IPC: E21C49/00
Filed: 1941-04-10
Abstract: 545,098. Preparing peat. EDGEWORTH, K. E. April 10, 1941, No. 4757. Convention date, Nov. 20, 1940. [Class 50] Peat fuel having great power of cohesion is obtained by the use of peat having a moisture content of from about 80 to 90 per cent, the peat being macerated and pressed into blocks which are then dried. The required moisture content may be obtained by cutting a thin layer of peat from the surface so adjusted in depth that the combined moisture contents of the comparatively dry outside layer and of the moister layer below together make up the desired content. Alternatively, the cut peat is first dried until the desired moisture content is obtained before the macerating, pressing, and drying takes place. Such peat blocks are well adapted for the production of peat charcoal. A machine for use in the process and capable of being propelled over the surface of a peat bog has means by which the depth of cut can be adjusted, a macerator, and a block pressing device such blocks being deposited on the surface of the bog, and collected when they are dried.

Abstract: 683,454. Ventilating crankcases. BECKETT., R. C. March 2, 1951. No. 5146/51. Class 7 (ii). A pin 4 is supported within a chamber 11 having an outlet 10 connected to an engine manifold, and projects through a metering orifice 18 in a diaphragm 12, which may be corrugated, extending across the chamber and biased by means such as a spring 19 towards the chamber inlet 13 communicating with a crankcase connection 6. The pin tapers from the outlet to the inlet side of the diaphragm. There may be a filter element 28 to cleanse the crankcase gases, and a removable sediment bowl 25. The manifold vacuum causes the diaphragm to move upwardly to progressively decrease the flow area of the orifice and the bias of the spring is such that under idling conditions of the engine the orifice is adjacent point 21 of the pin so that the flow area is a minimum. The pin may have an oppositely tapered portion 23 so that an increase in manifold vacuum is prevented when the flow area is increased by movement of the diaphragm above the point 21.

In an open fireplace according to the parent Specification, having one or more outlets in the fireback below the level of the grate for the supply of air from outside the room space, and baffles behind each outlet to prevent ash falling into the airway leading to the outlet, the airway includes a preheater for the combustion air. A common conduit 11 leading to outlet boxes 23, Fig. 1, at either side of the fireback has its top wall on a level with the hearth, so that it is heated by ashes in an ash pan resting on it. The conduit 11 has front and rear openings 28, Fig. 7, for the connection of a duct leading below the floor, or outside the building, the unused opening being closed by a blanking plate 29. A recess 40 formed in the top of the conduit 11 accommodates a rod 37 if a damper in a rearwardly directed duct is to be operated. An oval, butterfly damper 32 in the air duct is operated by a push-rod 37 having a lug engaging a hole in an arm 34 secured to the top of the damper spindle 33. The recess 40 and the front part of the hearth is covered by a plate 41 secured in rebates around the upper edges of the conduit 11. The open-ended conduit 11 is secured to plates 10 forming part of the fire-back cheeks, and having openings registering with the open ends of the conduit below outlet openings 20. A baffle 21 with side wings 22 is integral with the plate 10, and the outlet boxes 23 are secured to the back of the plates 10. Firebrick side cheeks arranged in front of the plates 10 have air outlet openings 49. A boiler 67, Fig. 8, with a central flue passage 69 may be arranged to form the upper part of the fire-back and sidecheeks, the walls at back of the rear flue from the grate to the flue 69 forming an acute angle 76 so that turbulence in the gases heats the water in this part of the boiler very strongly. The fireplace may have an all-night type of front, with an adjustable ash-door 58 to allow' some of the air for combustion to be taken from the room.
