Abstract: 600,021. Lens mountings. HALLIMOND, A. F. March 12, 1945, No. 6171. [Class 97 (i)] An objective mounting for a microscope comprises two complementary parts (one of which carries an objective and the other of which is secured to or forms part of the microscope body), one of said parts including a passage extending normally to the microscope axis while the other part has a slideway loosely slidable in said passage, the objective being centred by means provided on the two parts which are locked together by a clamping device. The part shown in Fig. 1 has a threaded tube 2 for securing it to the microscope body and a flange 1, which is apertured at 9 in the light path ; this part also has a member 3 fixed to the lower face so that a gap is left to receive the ribs 20 of the objective carrier, shown in Fig. 3. Grooves 6 in the member 3 receive limbs 7 of a forked angle lever 8, which rocks on the edge of flange 4 of member 3 and is apertured to clear a screw 5, carrying a locknut 11 and spring 12. The objective carrier, Fig. 3, is apertured at 17. in the light path and has a threaded socket 15 to receive an objective. Between the ribs 20 on its upper surface and the part apertured at 17 is a passage 18 which is closed only at the wall 19. The two parts are assembled by slackening the nut 11 and sliding the carrier over the member 3 until a screw 21 in the wall 19 engages a notch in the side of member 3, the limbs 7 engaging the underside of ribs 20. The objective carrier is then pivoted about screw 21 to centre the objective until a screw seated in the carrier, whose axis is orthogonal to that of screw 21, engages a side of member 3. Nut 11 is then tightened so that three projections 16 on the upper surface of the carrier press on the lower face of flange 1 and the limbs 7 and ribs 20 lock the two parts together. Limbs 7 and ribs 20 may be bevelled at 13, 24 respectively to afford easy engagement.

Title: Improvements in or relating to cranes
IPC: B66C23/36
Filed: 1928-02-29
Abstract: 312,619. Ransomes & Rapier, Ltd., and Lewis, R. S. Feb. 29, 1928. Steering-gear and steering; relay or power apparatus.-To facilitate manoeuvring in a confined space, the slueing platform of a railless travelling crane may be coupled at will to the steering mechanism by a connection operable from the platform so that slueing of the jib is accompanied by turning of the steering wheel or wheels. Fig. 2 is an inverted plan and Fig. 3 a sectional elevation of a crane in which the coupling may be effected by moving a hand lever 0 near the driver's seat on the slueing structure C. With the steering-wheels straight and the jib central, movement of the lever 0 in one direction will engage a slider N on the slueing table with a jaw M<1> of a wheel M fast on a shaft J journaled in the chassis, so that rotation of the platform C turns the shaft J and operates the steering-gear E' by means of a cam K on the shaft and levers L<2>, L<3> pivoted on the chassis. The cam is shaped so that the wheels are turned only through a predetermined angle from the mid-position, and continued movement of the slueing platform turns the wheels back again as the jib comes to point in the opposite direction. In any position of the mechanism, movement of the hand-lever 0 in the opposite direction tightens a brake-band P on the wheel M so as to lock the steering mechanism to the slueing platform. Slueing is effected by a motor arranged vertically on the platform C, and the controller for this motor is in the form of the usual steering-wheel. The crane may be operated by an internal-combustion engine on the platform, driving a dynamo supplying current to the various motors. The chassis may be propelled by motors F to which current is supplied by cables passing through the hollow post J. Interlocking.-The motors F may be provided with a reversing switch operated automatically when the jub is turned through more than a right angle.

Abstract: 1535235 Refrigerating PHILIPS GLOEILAMPENFABRIEKEN NV 20 Feb 1976 [24 Feb 1975] 06783/76 Heading F4H A cooling device for use in a closed space, e.g. a Dewar vessel 1, containing a liquefied gas 2a comprises a heat-exchanger 12, a flow restrictor 13 and a cooling element 3 connected in series between inlet and outlet ducts 4, 5 for a cooling medium, the heat-exchanger being located in the space upstream of the flow restrictor. As shown, the inlet and outlet ducts of a pair of Dewar vessels communicate with ducts 6, 7 of a circuit which includes a pump 11 and a heat exchanger 8 associated with the cold head 9 of a cold-gas refrigerator 10. The pump circulates liquid hydrogen through the circuit and, in normal operation, the liquid hydrogen in the heat-exchanger 12 is cooled by vapour in the space 2b and flows through the restrictor 13 to the cooling element 3. If the vacuum jacket of the vessel leaks, the resultant temperature rise in the vessel causes evaporation of the liquid hydrogen in the heat exchanger 12 and flow of the resultant gas is prevented by the restrictor 13. The heat exchanger 12 may be located in the vapour space 2b, or in the liquid space 2a, Figs. 3-6 (not shown). A further heat exchanger may be provided between the heat exchanger 12 and the restrictor 13.
