Title: Improvements in micrometer screw gauges
IPC: G01B3/18
Filed: 1932-06-10
Abstract: 397,631. Linear-dimension gauges. NEWTON, R., The Brambles, Cudworth, near Barnsley. June 10, 1932, No. 16428. [Class 106 (ii).] In a micrometer callipers more especially for setting the cutters of boring bars, the head carrying the adjustable anvil and operating thimble is longitudinally adjustable in the frame and the fixed anvil is of V-shape. The frame 1 has a head 4, the axis of which is in line with the apex of the V-shaped anvil 2, and the head is slidable in a split journal 5 to which it may be clamped by a screw 10. In use, the boring bar is placed in the V-shaped anvil, the clamp 10 released, and the head 4 pushed until the anvil 8 contacts with the bar 11. The head 4 is then gently clamped and the thimble 9 rotated until " zero " is indicated, the head being gradually thrust back to allow for the forward movement of the anvil. The head is then clamped tightly. The anvil 8 is then moved back by rotating the thimble until the gap is in excess of that required and the cutter, which is lightly clamped in the bar, moved into gauging position. It is moved by the advance of the anvil 8 to its correct position in which it is clamped. In some boring bars the hole for the cutter extends right through the bar. For these the anvil 2 has a central bore into which a screwdriver may be inserted or that contains a permanent screwdriver 15 with a milled head for moving the screw 13 to adjust the cutter. In another form, a slotted anvil may pass right through the bore in the anvil 2 and may be adjusted to project beyond it to be used in the ordinary way. The head 4 may be threaded through the limb 6 of the frame.

Title: Improvements in or relating to the moulding of thermo-setting plastics
IPC: B29C35/08
Filed: 1943-10-12
Abstract: 572,425. Dielectric heating thermosetting plastic. BAKELITE, Ltd. Oct. 12, 1943, No. 16680. Convention date, Dec. 11, 1942. [Class 39 (iii)] [Also in Groups V and XXXV] A method of moulding a thermo, setting plastic comprises the steps of (a) inducing heat within the plastic mass by subjecting it to the action of a high frequency electrostatic field, energy being supplied to the field at such a rate that a hardening temperature is reached within the mass before a degree of hardening interfering with plastic flow is obtained, (b) shaping the mass in a mould by pressure and (c) heathardening the. shaped mass. Preforms or sheets which are to be pressure-moulded may be heated between plates operating as a condenser and then quickly transferred to a hot mould which may be heated either by H.F. electrostatic field or in the usual manner, A number of preforms may be heated simultaneously by the field, e.g., by being carried between condenser plates by a movable belt, and enclosures may be provided for supplementary conduction or radiation-heating. Alternatively and as shown in Fig. 2, a condenser unit may be built into the mould and moulding powder or a preform, pre-heated by H.F. electrostatic field, is placed in the mould and simultaneously heated and pressed therein. The mould shown comprises top and bottom forces 42, 43 keyed at 47 to a top plate 46, and a chase 41 keyed at 45 to a bottom plate 44. These parts are made of insulating material such as mica-filled ceramic material. The forces are lined with non-ferrous metal (brass,. copper, bronze) sheets 53, 54 to form electrodes. Leads 48, 49 from a highfrequency generator terminate in contacts 50, 51. The mould may be placed between the platens of a press; the plates 44, 46 may be fixed to the lower and upper platens. Fig. 1 shows a circuit for generating high-frequency oscillations, in which plate electrodes 1 are fed from a 220-volt A.C. supply through an auto-transformer 15, power-transformer 17, two half-wave mercury arc rectifier tubes 18, 19, audio-frequency filter choke 33, radio-frequency choke 36, tank coil 6, radio-frequency coil 5 and tuning condensers 2, 3, 4. The operating frequency is determined largely by the sizes of the coil 6 and its associated plate condenser 7, which are connected to the plates of oscillator tubes 8, 9 operating in push-pull. The plate current can be varied over a large range by a small adjustment of the condenser 4. The Specification as open to inspection under Sect. 91 states that the heating of the material may be carried out partly by high-frequency and partly by heating in an oven, to a point below that at which hardening is initiated, heating being continued by means of a H.F. electrostatic field. This subject-matter does not appear in the Specification as accepted.

Filed: 1938-06-08
Abstract: 514,812. Drying webs of woven or knitted material. JAHR. W., [trading as JAHR, M. R. (Firm of)]. June 8, 1938, No. 17047. Convention date, June 8, 1937. [Class 34 (i)] [Also in Group VIII] The amount of slack of wet woven or knitted webs fed to a drying machine to allow for shrinkage of the webs therein and hence the desired relative speeds of the feed and the conveying means in the machine to allow of this compensation, is determined according to the number of meshes or weft threads per unit of length in the wet material. A known counter is used, but a counter of the type described in Specification 163,364, [Class 42 (ii)], is preferred. The web of material 2 carried by tentering chains 1 is supported so as to be without tension by a housing 3 covered by a glass plate 5. The housing, which contains a lamp 4, presses the fabric against the counter 7 and the desired measurement is read off on a mirror 10 arranged at 45 degrees to the rays of light proceeding from the lamp 4, lens 9 being interposed. An additional lamp 8 may be used. The preferred counter 7 comprises a transparent plate ruled with a series of diverging lines symmetrical to its axis. When in position over the parallel threads of the fabric an interference pattern is produced and is projected on to the mirror together with the scales on either side of the plate. A clear space free from interference is produced in the pattern and corresponds to the place where the number of threads and the diverging lines are identical and this number may be read off from the. scale.

Abstract: 224,204. Atlas-Werke Akt.-Ges. Nov. 3, 1923, [Convention date]. Addition to 137,858. Operating and controlling doors hydraulically. - In order to simplify the arrangement claimed in the parent Specification, the distributing valve controlled by the piston R' is replaced by a free piston R<1> which acts directly as a distributing member in the cylinder R. The piston R' always sets itself so that there is pressure water over the piston of the door cylinder if a door is closed at a local station through the double three-way cock W after the main valve H a the central control station has been set to the '' doors closed " position. With the cock H set to this position, pressure fluid is led from the pipe M through the fourway cock V into the pipe T to the cylinder R. This forces the piston R<1> to the right-hand side in its cylinder and permits pressure fluid to pass to the upper side of the cylinder to close the door, as represented in diagram I. When the three-way cock is moved to position shown in diagram II the return path of the discharge water is through the pipe J, pipe B and valve H to the discharge main D. To open a bulkhead door at a local station with the valve H in the " doors closed " position, the valve V is moved into the position shown in diagram III. Water under pressure then passes through the pipe M, valve V and pipe K into the lower part of the cylinder Z, the upper part of the cylinder communicating with the pipe D through the pipes L, T, J. When the valve H is positioned at the central station for the " doors open " position, the piston R<1> is moved to the left-hand side of its cylinder.
