Title: Improvements in machines for polishing, grinding or waxing flat surfaces
IPC: B24B45/00
Filed: 1925-09-05
Abstract: 239,852. Alers, R. A. J. M. Sept. 9, 1924, [Convention date]. Buildings, floors, and walls, cleaning. - In a portable electrically driven machine for polishing or waxing flat surfaces, the tool 2 is carried by a circular member 1 having formed therein a chamber within which the end of the driving- shaft 6 is located. In order that the tool may rock slightly on the shaft, and to allow of pressure being put on the tool, the chamber comprises a part 7 of square section and a spherical seating 8, the end of the shaft being formed with a head having spherical portions 9, one of which engages the seating. The sides 10 of the head, which engage the part 7, are of cylindrical form, the axes of the cylindrical portions being situated in a plane perpendicular to the axis of the shaft 6 and passing through the centre of the spherical surfaces. A cap 11 retains the shaft in position and has an opening 12' of a size to allow of the rocking of the shaft, and a spherical seating to receive the other spherical portion of the head.
Patent GB-909094-A (GB)
Title: Improvements relating to visual indicating assemblies
Inventor: SOLARI FERMO
IPC: B61L25/04
Filed: 1959-06-29
Abstract: 909,094. Electric selective signalling systems. SOLARI & C./UDINE S.p.A. June 29, 1959, No. 22256/59. Class 40 (1). The stepping circuit for a seeking switch of an indicating arrangement comprises two relays A (not shown) and X, Fig. 3, one bank of contacts II on the switch and the solenoid I for advancing the switch. Each energization of the driving solenoid I advances the switch arm 9 from a position between two contacts (as shown) to a position between the next two contacts. Relays A and X are both slow to release and have their contacts A1 and X1 respectively open and closed when they are de-energized. In operation, application of a voltage V energizes relay A which energizes the driving solenoid I via its contact A1 (contact XI being normally closed). This causes the arm 9 to advance one step and in so doing it brushes over one of the fixed contacts 10. This, in turn, momentarily energizes relay X, thereby opening its contact XI (which remains open as relay X is slow to release) and finally contact A1 opens followed by the closure of contact X1 (relay X having a longer release time than relay A). The circuit has then returned to its initial condition and if the voltage V is still present a further advance, as before, of the switch takes place. The switch is caused to stop at a selected position by means of a further bank of contacts IIa, Fig. 4, one of which is marked by a selected contact 25. When the switch reaches the marked contact (switch 9a unlike switch arm 9 steps from contact to contact) a relay D is energized to open its contact D1 which is interposed in the circuit for the driving solenoid I. A final embodiment, Fig. 6, shows a master seeking-switch with a driving solenoid I and two slave or follower stepping switches, situated at remote points, with driving solenoids III and V, all three driving solenoids being connected in series. Only the master seeking-switch has means (contacts 25 as in Fig. 4) for selecting a desired stopping position. In operation a contact of a bank of the master switch is marked by a selected contact 25 and a potential V is applied. Relays A, B and P then close, energizing all the driving solenoids in series. As each switch arm 9 advances it brushes over a contact 10, thereby energizing an associated relay X, Y or Z. When all three relays have been energized, signifying that all three switches have advanced, relay A is de-energized and a further step is made until eventually when the switches reach the desired position relay D is energized to open the circuit to the driving solenoids by its contact D1.

Filed: 1927-08-26
Abstract: 276,688. Akt.-Ges. Brown, Boveri, et Cie. Aug. 28, 1926, [Convention date]. Regulating; motor power plant.-Fluid-pressure operated valves b, c, d for the groups of nozzles e, f, g of an ahead turbine, a and, it may be, the similar valves i, k for the nozzle groups l, m of the astern turbine h are controlled by one-hand operated device 3. Pressure fluid is supplied under pistons I - - V by a pump n and the pressure at the pistons is determined by the leakage into a return pipe 2 permitted by a piston valve VII. When the piston valve is moved to the left to throttle the outlet from the pipe p the pressure in that pipe rises and since the bladings on the pistons are suitably differentiated the valves b, c, d can be caused to open in succession. When the piston valve is moved to the right the valves i, k are similarly operated. A quick closing valve s in front of the nozzle valves is normally held open by the fluid pressure and closes when the pressure fails by reason of the operation of emergency devices t, u or a hand-controlled valve 3. The valve 3 may be operatively connected with the piston valve VII. Separate pistons valves may be provided to control the valves of the ahead and astern turbines respectively.

IPC: F02K9/34
Filed: 1952-09-08
Abstract: A rocket tube, i.e. a tube closed at one end so as to be capable of imparting a directional thrust to itself or another body when said tube is caused to contain a high internal pressure, are constructed from glass fibres impregnated with synthetic resins, e.g. polyesters, phenolics and melamine resins.  The tube may be formed by dipping the glass fabric in the liquid resin or in a solution of the resin, winding it under pressure on a core until a vessel of the required thickness is obtained and curing the resin by heat, e.g. at 130 DEG C.  Metal inserts may be embodied in the vessel and the forward end of the tube may be fitted with a threaded metal ring for the attachment of a warhead while the rear end may be constricted to a throat provided with a heat-resistant lining, e.g. of metal or asbestos reinforced plastic.

A tool for drawing workpieces having at least one oblique portion includes a drawing die, the part of the die which is arranged to shape the oblique portion of the workpiece being arranged for sliding movement transversely of the drawing direction in a guideway provided on the main part of the drawing die, whereby the shape of the die is varied in accordance with the progress of the drawing operation and the form of the workpiece. In an embodiment, the die 1 is U-shaped and a transversely slidable die part 4 is guided in grooves 5 (Fig. 6) in the die opening. A U-shaped work-holder 2 also accommodates a transversely displaceable part 10 which may be bolted to the die part 4. In operation, as the drawing commences the workholder part 10 causes the die part 4 to be carried along as the holder part is moved transversely by a punch 3 and as the drawing proceeds the work-holder part acts as a brake on the die part 4. The transverse movement of the die and/or the work-holder part may be controlled in dependence on movement of the punch by cams, cam slots or linkages (not shown).

[Also in Division G1] In apparatus for measuring the refractive index of liquids, a comparison beam 2 and a measuring beam 3 are reflected at the same point 9 along an interface between a liquid sample 7 and a semi-cylindrical or hemispherical reference body 6, the angle of incidence αM of beam 3 being smaller and the angle of incidence α V  of beam 2 being greater than the critical angle of total reflection. The beams are produced with the aid of a double diaphragm 4 and are periodically and alternately passed in phase opposition by a rotating diaphragm wheel 13; beam 2 is totally reflected at the interface, and the reflected light intensity of beam 3 is governed by the ratio of the refractive index of body 6 to the refractive index of the sample 7 Fig. 2 (not shown). The reflected beams are focused through a lens 10 on to a photo-cell 11 which is uniformly lit by a diffuser 12; the voltage pulses falling across a working resistance 14 are fed to an amplifier 15 and separated into measuring and comparison signals whose difference or quotient is formed in 16 and indicated at 17. A narrow wavelength region may be screened-out by an optical filter arranged between the light source and diaphragm 4 and the arrangement may be adapted to different measuring ranges by rotating the reference body and the receiving device about the focusing point. A light-dimming device may also be provided in the path of beam 2 to equalize the light intensities of the two beams.
