Title: Method of and apparatus for the automatic measurement of fuel  filtrability temperature limit
IPC: G01N33/28
Filed: 1971-04-26
Abstract: 1325078 Measuring fuel filtrability electrically COMPAGNIE FRANCAISE DE RAFFINAGE 26 April 1971 [27 April 1970 19 Aug 1970] 11404/71 Heading G1N The filtrability temperature limit of liquid fuel i.e. the temperature at which the transit time of the fuel through a standard metal filter exceeds a predetermined value due to the fuel solidified in the filter is determined by apparatus including a refrigerated chamber 101 for the fuel, a temperature sensor 10 measuring fuel temperature and supplying an electrical signal representative thereof to a first comparator 30 receiving also a reference temperature signal from a circuit 20 and actuating, at signal equality, a second comparator 40 to commence filling of a pipette with the cooled fuel via the standard filter and to trigger a time base 60 which receives from photo-electric liquid level sensor 70 and pulse generator 80 a signal representative of a full pipette which signal, if it occurs within a predetermined interval of the time base start e. g. 60 seconds, indicating filterability is too high, acts to reset the time base, empty the pipette and lower the reference temperature by a predetermined decrement, to re-cycle the process. If the time is not less than the predetermined interval a time comparator circuit 90 acts to cutoff the second comparator so that the pipette is emptied while the reference temperature circuit 20 is locked so that the reference temperature is permanently displayed on meter 24 whilst the indicator 93 indicated that measurements are complete. Liquid level may be determined by a capacitive or photo-electric pick-up.

Title: Mechanical-hydraulic device for feeding working units of multiple unit machine tools
IPC: B23B47/22
Filed: 1962-03-26
Abstract: 950,420. Slides and carriages. TOS KURIM NARODNI PODNIK. March 26, 1962 [March 29, 1961], No. 11439/62. Headings B3B and B3C. A mechanical-hydraulic device for feeding working units of multiple unit type machine tools comprises a working unit 1 displaceable in a bed 2 by a screw-and-nut drive mechanism, 3 and 4 respectively. An electromotor 6 and rotary hydraulic motor 9 interconnected by gear-wheels 7, 8 and 11 and a coupling 10 provide in a given sequence the power for rotation of the screw 3, with subsequent rectilinear movement of the unit 1. The hydraulic motor is connected to a constant pressure hydraulic ring main supply, to which all such units are connected in parallel, the oil being continuously supplied to the motor from a pressure line 14 through pipe 13 via filter 12. Regulation of the oil flow is effected by a valve with a stabilizer 17. The operation of the feeding device is effected in two stages, a fast traverse provided by the electromotor 6 and a slow traverse by the hydraulic motor 9 and their interoperation is as follows. The pressure feed to the hydraulic motor promotes the rotation thereof, which is continuous, and is regulated by the stabilizer 17. When the unit 1 is being fast traversed, the hydraulic motor is disengaged by the coupling 10, with the shutting off of the electromotor the coupling is automatically engaged which connects the hydraulic motor to the drive mechanism and at the same time rapidly and continuously brakes the electromotor, the slow traverse now being effected by the hydraulic motor. Similarly, in reverse, the coupling is automatically disengaged when the electromotor is started for the return fast traverse. A number of work units may be connected from the common constant pressure hydraulic system since each unit is connected in parallel and each takes a constant supply of oil from the system irrespective of the stages of operation.

Title: Improvements in or relating to the manufacture of jet nozzles
IPC: B21K21/08
Filed: 1944-06-20
Abstract: 577,590. Making nozzles. NAPIER & SON, Ltd., D., and BACK, J. A. June 20, .1944, No. 11698. [Classes 83 (ii) and 83 (iv)] Nozzles, for the delivery of a flat jet of liquid as described in Specification 577,589, are produced by rolling a blank to form a venturi throat and then compressing the mouth to produce a slot-shaped orifice. Axial rolling.-A blank H<1>, Fig. 3, with bore H' is mounted for rotation and axial feed to rolls G, of general elliptical shape in axial crosssection, mounted to rotate in a cup E having an internal spherical surface on which the rolls rotate. A housing A has a flange A<1>, to provide a fixed mounting in a lathe &c., and carries ' two-diameter sleeve B internally threaded at E<2> to receive a threaded member C<1> having a flanged end threaded at C<2> to engage threads on the cap E. Pins E<1> engaging slots in the sleeve B restrain the cap from rotation and the member C<1> is splined in a worm-wheel D. The threads B<2> and C<2> are of the same hand, but differ in pitch so that axial movement of the member C<1> produced by rotating the worm L causes a reduced movement of the cup E. A central sleeve F has a head that abuts a shoulder C<4> on one side and the rolls G on the other. The bore H<2> is slightly flared to engage the end of a spring-pressed mandrel J in the sleeve F and this is forced back as the blank advances. At the same time the rolls are gradually moved from the position shown in Fig. 1 to that shown in Fig. 3. The diameter in the throat of the nozzle is controlled by a mandrel K<1> supported by a rod K within the mandrel J. When the throat is reduced to the correct size, the rod K rotates with the work and the clicking of a pawl on a ratchet-wheel K<2> indicates this to the operator. Forging-machines.-For flattening the mouth, the rolled nozzle is mounted in a holder M, Fig. 7, held by a clamp M<1> with the nozzle H between jaws O sliding in guides Q<1> under the control of levers P' pivoted at P<1>, normally held open by a spring P<5> and closed by a wedge S<1> actuated by a lever R having a pin R<4> to engage holes N<1> in the base to lock the jaws in either the closed or the open position. The nozzle is located by a stop S<4> retracted by a spring S<5> when the pin S<3> retires on movement of the wedge S<1>. In a modification, the nozzle is flattened by segmental jaws oscillating in a cylinder as controlled by a rotatable cam, perpendicular to the cylinder axis, and situated between the ends of the segments remote from the jaws. Each jaw is provided with an .opening-spring.
