Title: Improved means for teaching topographical surveying
IPC: G09B25/06
Filed: 1950-05-15
Abstract: 688,485. Teaching surveying. RAZMA.RA, H.A. May 15, 1950. No. 12080/50. Class 146(ii). Apparatus for teaching surveying comprises a table 2 on which is placed a relief model of a land area, a part raised above the table to support an alidade holder 7, and an alidade consisting of a horizontal rod 9 and four vertical rods constituting respectively a station-indicating leg 11, a graduated stadia 12, a levelling staff 13 and a scale 14 for measuring angles of elevation. The raised part of the table may be constituted by a, shelf with vertical legs or may comprise a skeleton frame 4 with transverse bars 6, and carries the holder 7 which has a tube 8 in which the leg 11 can slide vertically and turn. The point 15 of the leg 11 is arranged to rest on the part of the model 1 representing the location of the station from which obesrvations are to be taken. The rod 9 is fixed at its mid-point to the leg 11 by a screw 43 and is adjusted to horizontal position by a spirit level 28 and a counterpoise weight 10. The stadia 12 and staff 13 are adjustable along the rod 9, the former being fixed at one of two set positions and having two sets of graduations corresponding to the two positions and the latter being moved until its point 21 rests on the part of the plan whose distance from and height relative to the station are to be determined. A point 17 or the leg 11 is employed to represent the optical centre of the alidade and a wire 18 is attached at the point to represent the sighting line. Marks 22, 23 on the staff 13 represent the usual upper and lower targets, the mark 22 being level with the point 17 when the points 15, 21 are at the same level. The scale 14 is graduated in angles and marked with the tangents of the angles. In use, after the points 15, 21 have been located at the appropriate points on the model 1, the stadia 12 is adjusted vertically until the infinity mark of its scale is in line with points 17, 23, this being effected by means of the wire 18. The wire 18 is now stretched taut so that it passes through the target point 22. Where the wire crosses the stadia 12 and scale 14, the scales will indicate respectively the distance from the station of the point being investigated and the tangent of the angle of elevation. From these data, the difference in heights can be calculated. A plane table 29 rests on the alidade holder 7 and carries the paper on which the locations are plotted. A pin on the paper represents the station, and each point is plotted by holding a ruler 35 parallel to the rod 9 and measuring from the pin the distance obtained as described above. An arm attached to the leg 11 may move over a scale on the holder 7 to indicate the angular directions of the rod 9. A mark 19 on the leg 11 may be used as the optical centre instead of the mark 17, if more convenient, in which case marks 23, 24 on the staff constitute the lower and upper targets respectively.

Title: Improvements in self-regulating motor-generator sets
IPC: H02K47/14
Filed: 1942-09-02
Abstract: 558,830. Motor-generators. VERITYS, Ltd., and BLACKLEDGE, R. S. Sept. 2, 1942, No. 12363. [Class 35] In a motor-generator set of the kind in which the generator has a self-excited shunt field, variation of the generator voltage with fluctuations of input voltage to the motor are minimized by providing the generator with a differential shunt field separately excited from the input voltage to the motor. As shown, a motor 2 having a shunt winding 3 and input terminals 5, 7 drives a generator 8 having a self-excited shunt winding 9 controlled by a manual regulator 10. A cumulative compound winding 14 for the generator is also provided, being excited by the line current to the motor. A differential winding 15 supplied through a reversing switch 18 from the motor input terminals is also provided on the generator, the switch 18 normally being in position 7, so that the flux from the winding 15 opposes that from the self-excited shunt field 9 and compound winding 14. When it is desired to obtain a higher voltage from the generator, e.g. for battery charging purposes, the switch 18 is thrown into the position Y so that the separately excited winding 15 assists the self-excited winding 9. A contactor 17 operated by the voltage across the generator terminals is arranged to open the circuit of the separately energized shunt winding to prevent demagnetization or reversal of magnetization of the generator field when the machine is being started or stopped.

The gearing comprises an epicyclic arrangement in which a planet-wheel 11 engaging the pinion 9 also engages an internallytoothed ring 12 formed either on the upper or lower surfaces of the lower frame-plate 4 which may be of insulating material. The planet-wheel is carried by a block 13 secured to the sleeve 10, the block being slotted at 14, Fig. 2, so that the position of the wheel with respect to the spindle 8 may be varied slightly to enable it to mesh smoothly. The wheel 11 is made hollow and in two parts connected by a spring so as to take up backlash. An alternative arrangement for taking up backlash comprises a planet-wheel divided into three parts as shown in Figs. 5 and 6, the middle one of which is provided with spring- urged pins 16 each engaging one of the outer parts. The wheels 9, 12 are so disposed in relation to the planet-wheel that one engages the centre part and one outer part whilst the other engages the centre part and the other outer part of the planet-wheel. In a modification, Fig. 7, a train of friction wheels 17 - - 20 are employed for effecting speed reduction between the spindle 8 and sleeve 10, and in this form the stub shaft 21 carrying the wheels 19, 20 is eccentrically disposed in relation to the part secured to the frame plate to enable rubber tyres provided on the wheels 18, 20 to be compressed to adjust the friction. Friction wheels may be substituted for the toothed gearing shown in Fig. 1 and toothed gearing may be employed in the arrangement shown in Fig. 7.

Title: Improvements in electrically operated clocks
IPC: G04C13/04
Filed: 1930-04-23
Abstract: 352,582. Electric clocks. MERCER, T. and MERCER, F., Eywood Road, St. Albans, Hertfordshire. April 23, 1930, No. 12588. [Class 139.] An electric clock system of master and secondaries has manual switch mechanism whereby the hands of a particular secondary clock (having the switch) and the hands of other secondaries in series may be stepped-on simultaneously,. there being means for automatically disabling the switch when a normal, time-transmitting impulse passes from the master to the secondary clocks. The invention is particularly for use on ships, for correcting for the difference between Greenwich and local time. The drawings illustrate the particular secondary, carrying the manual switch 12 ; terminals 4. 5 are connected to the master clock; 6, 7 to the other secondaries ; and 8, 9, 10 to the electric source. As described in Specification 352,583, each impulse from the master clock energizes a magnet 3 which attracts its armature 36 to close a circuit at 11 to the other secondaries in series. On the return a pawl 38 feeds a ratchet 37 driving the clock hands. When magnet 3 is energized from the master, a polarized relay 13 in series is also energized. To advance the hands of the secondary clock shown and of the other secondaries, a plunger switch 12, 15, Fig. 3, is operated the necessary number of times to energize the magnet 3 to step-on the secondaries the required amount. When switch 12, 15 is operated, relay 13 is not energized since it is not in circuit. If, however, during the manual switch operation, an impulse from the master energizes magnet 3, then relay 13 is energized and its armature 18 lowers a tongue 21 into a gap 22 in the plunger of the switch 12, so that the latter cannot be operated. This switch comprises a slide 14 with members 23, 24 guided by a fixed bar 16, to which is pivoted at 29 a cam 28 coacting with contact-blades 30, 31. A spring 32 connects slide 14 and cam 28. When the slide is pushed to the left, Fig. 3, against spring 25, lost-motion occurs until the line of spring 32 passes over the dead-centre, whereupon cam 28 closes the blades , 30, .31 ; a. similar lost-motion occurs when the slide 14 returns to the right. These contacts, 30, 31 are in circuit with magnet 3 so that only the latter and not relay 13 is energized.
