Abstract: 856,934. Merry-go-rounds. CHEREAU, A., and DE VOS, H. April 4, 1957 [April 20, 1956], No. 11021/57. Class 132(1). A merry-go-round comprises at least one car carrying arm 2 pivoted to a rotatable member 1 and displaceable vertically about its pivot by a pressure fluid actuator 3 to and from which fluid is routed by valve means controllable by main and auxiliary control means operable respectively from within and from outside the car. As shown, an annulus 1 revolves about a vertical shaft 1a carrying with it a series of car carrying arms 2. Each arm 2 is supported at 9 by the rod 3a of an actuator 3 pivoted to annulus 1 and is pivoted at its end 6 to a rod 7 pivoted at 8 to the annulus. A sliding carriage 5 carried on rod 3a slides in vertical guides (not shown) so that rod 3a operates the arm vertically. Pressure fluid, e.g. compressed air, is supplied to the lower part of actuator 3 through a line 10 controlled by an electro valve 11. A branch line 12 from line 10 is connected through electro valve 13 with the atmosphere. Thus by operation of valves 11 and 13 fluid may be supplied to and allowed to escape from actuator 3. The shaft 1a carries insulated conductive rings 14, 15, 16, 17 engaged by brushes. One pole of the electricity supply is led through a brush to ring 16 which is connected through a brush to valves 11, 13 whose other terminals are connected to terminals 18, 19 in car N and to rings 15 and 14 through brushes. A contact 20 in car N is connected through a brush to ring 17 which is connected to a contact 20a which can be connected by contact 1c with the second pole 21 of the current supply. When contact 1c engages contact 20a valves 11 and 13 may be operated by the occupant of car N connecting contact 20 with contact 19 or contact 18. Rings 15 and 14 are engaged by brushes which are connected to contacts 18a and 19a which may be connected by contact 1c to the pole 21 to operate valves 13 or 11 if the passenger fails to operate a switch. Actuator 3 may be a doubleacting cylinder. Coupling strips may be provided by means of which the operator acts on the switches 1c to move the arms up and down. The arms are preferably raised and lowered, e.g. in groups. the contacts being staggered or of different lengths.

Title: Improvements in printing telegraphs
IPC: H04L21/00
Filed: 1941-01-17
Abstract: 574,350. Facsimile telegraph apparatus. EVANS, G. T., MORRELL, F. O., and FINLASON, W. E. Jan. 17, 1941, No. 11025/42. Divided out of 574,349. [Class 40 (iii)] A facsimile telegraph receiver comprises a rotary member having a number of arms corresponding to the number of lines in any character according to the code selected, each arm being adapted to pass current impulses from a transmitter to chemically prepared paper suitably fed through the receiver. In the code shown in Fig. 1, each character is divided into five lines of five elemental areas. The marking wheel g, Figs. 2 and 4, has five arms g<1> corresponding to the five lines of the code. Each arm g<1> has a contact point g<2> adapted to wipe transversely over the surface of a chemically prepared paper tape f which is gradually moved through the receiver. The tape is moistened or impregnated before it reaches the marker by being brought in contact with a wick i<1>, dipping in a reservoir i. This is brought about by the depression of the tape by means of a roller i<2> on an arm i<3> rocked by a rod i<4> and a cam i<5> on the shaft of the marker wheel g. The rotation of the marker wheel is controlled by a one-revolution clutch periodically released by an electromagnet h receiving synchronizing signals from a transmitter. This receiver is intended to be combined with the transmitter described in Specification 574,349. The combination circuit is shown in Fig. 2. It includes a switch m operated by a cam in the receiver to switch off the electromagnet h directly the receiver clutch is operated to receive printing signals, thereby to guard against " double revolutions." In the combination circuit, the switch m when it breaks the circuit of the electromagnet h at the same time puts the relay k<1> in parallel circuit with the marker g. The inductance of the relay across the marker has been found to reduce smudging.

Apparatus for coating a metallic sample 13 comprises a metal base 1 to support the sample, at least one plate 4 movable vertically with respect to base 1 and bearing a detachable stud 11 for clamping the sample against the base 1 and is characterised in that the stud is fixed in the plate by means of an electrically insulating ring 12 and is connected to one end of an electrical resistance measuring circuit, whose other end is earthed through the base so that the ohmic resistance of the contact between the stud and the sample can be monitored. Preferably the sample is housed in a dish-shaped element 18 and is surrounded by a cylindrical ring 14 held down by a plate 3. The plates 3 and 4 are movable vertically on column 2 supported on base 1 and can be held in a raised position by lugs 5 and 6. Coating material is applied to the sample 13 through a funnel 15 supported in a tongue 16 secured to the plate 4. In operation coating material e.g. a synthetic resin, flows around the sample 13 and also surrounds the base of stud 17. Should any coating material penetrate between stud 17 and sample 13 this will be indicated by the measuring circuit and steps can be taken to increase the pressure between the stud 17 and the sample 13 so as to restore electrical contact between them. At the end of the coating operation the resin solidifies and firmly holds the stud on the sample thus providing good electrical contact with the sample for subsequent operations, e.g. electrolytic polishing.

Title: Improvements in or relating to water waste preventing cisterns for flushing the pan of sanitary closets
IPC: E03D1/33
Filed: 1938-04-14
Abstract: 513,703. Water-waste-preventing cisterns. FARMER, B. F., [Representative of FARMER, C.S.]. April 14, 1938, No. 11454. [Class 26] A substantially air-tight flushing cistern having a manual ly-operated valve controlling the outlet is provided with buoyancy or pressure actuated means, or both, controlled by the waterlevel or gas pressure in the cistern and operatively connected to the outlet valve so as partly to balance the pressure on it and so facilitate its opening. In the cistern shown in Fig. 1 the outlet valve 16 is connected by a rod 17 to a float 20, and a second float 21 is carried by a lever 23 which passes through a slot in the rod 17 and carries a counterweight 27. The valve 16 is raised from its closed position, shown in broken lines, by a cam 30 operated through linkage from an external handle 34, the force tending to hold the valve closed due to the pressure in the cistern being largely counteracted by the float 20 and also the float 21 acting through the lever 23. After the valve has been initially lifted by the cam the discharge commences through ports 15 in the wall of the outlet pipe, and the lift is then completed by the float 20. As the water-level falls in the cistern the float 21 sinks and finally causes the valve 16 to close. If the initial pressure, before refilling of the, tank is atmospheric, the tank may be emptied completely at each flush, but if the pressure is above atmospheric (obtained by charging the tank with compressed air through a non-return valve 35) the tank is not fully discharged to prevent loss of pressure. In a modification the float 20 is replaced by a piston working in a vertical cylinder and subjected on its underface to the pressure in the cistern.
