Title: Improvements in a register actuator
IPC: G07B17/00
Filed: 1943-07-13
Abstract: 575,927. Registering mechanism. DEHN, F. B. (Pitney-Bowes Postage Meter Co.). July 13, 1943, No. 11369. [Class 106 (i)] A registering mechanism for a postal franking machine is provided with means whereby a half unit value as well as unit values may be entered into the register wheels. The machine described includes a die 10, Figs. 1 and 2, with a value printing wheel 11 manually adjustable by gearing 13, 14s and a knob 16. A gear 14 associated with the gear 14a meshes with a gear sector 17 fixed to the shaft 18 and having a projection carrying a settable pinion 21. Notches 19 in the sector co-operate with a detent member 23 to hold the sector in set position. The pinion 21 is associated with an actuator gear 27 and a transmission gear 28 loose on the shaft 18. Attached to the face of the actuator gear is a segment gear 29 that co-operates with a segment gear 32 on a drive shaft 33. Geneva locking surfaces 31, 34 on these gears serve to hold them in home position. The actuator wheel 27 has two teeth for each unit value and a space 44, Fig. 3, is provided between the teeth of the " 1 and " 2 '' value units for a " 1¢ " value setting. A cycle of operation is initiated by oscillating the drive shaft 33. At the start of a cycle, a pinion 35 is moved into mesh with the transmission gear 28 and during the cycle movement of the pinion 35 is transmitted by a gear 36 to the units wheel 38 of the register. Rotation of the shaft 33 through the segment gears 32, 29 drives the actuator gear 27 and thereby the pinion 21 which acts as a coupling drives the transmission gear 28. The pinion 35 is rocked out of engagement at the end of the forward stroke by means of a cam 41, follower 42, and a rocking lever 45 on which the pinion is supported.

Washing-machines with rotary receptacles. - The casing 10 in which the clothes receptacle 15 is rotated is pivoted at 12 to a stationary support 11 so that it may be swung from the position shown in Fig. 1, in which the receptacle is rotated at a high speed on a vertical axis for centrifuging, to that shown in Fig. 5 wherein the receptacle is rotated at a slower speed on a substantially horizontal axis for washing. In the centrifuging position the bottom of the receptacle is above the level of liquid in the casing. The shaft 20, driven from an electric motor 26, carries a friction gear wheel 23 and, through reduction gear 27, Fig. 5, drives a countershaft 28 on which a bevelled friction gear wheel 29 is mounted. In the vertical position the wheel 23 engages the plain lower frictional surface of a bevelled gear wheel 19 on the shaft 17 of the clothes receptacle, and in the inclined position the bevelled edge of the wheel 19 is engaged by the wheel 29. One of the bearings 21 of the shaft 20 is spring-cushioned. A spring buffer 33 cushions the movement of the casing as it arrives at its vertical position and tends to disconnect the friction gear wheels 23, 19. A lever 31 having a projection 30 which engages a wedge-shaped lug 32 on the casing is provided for locking the casing in its vertical position and forcing the gear wheels 23, 19 into frictional engagement. A cushioning device for the casing as it arrives at the washing position may be provided. The shaft 20 may also drive a crank disc 50 through a manually controlled clutch, the crank pin 45 of which engages a slotted lever 46 which works a pump supplying the hydraulic cylinder 36, the piston rod 37 of which is connected to the underside of the casing thereby facilitating its movement from the washing to the centrifuging position. The relief valve of the ram is manually controlled by a shaft 38. The casing may be provided with an electrical heating element. Reference has been directed by the Comptroller to Specification 2206/90, 270,147, and 300,048.

Abstract: 292,579. Siemens & Halske Akt.-Ges. June 24, 1927, [Convention date]. Addition to 288,288. Resistances, measuring; temperature errors, compensating for. - The cross-coil instrument forming the subjectmatter of the parent Specification has its temperature co-efficient compensated by including a resistance m in series with the directing- movement coil f, Fig. 1, and a second resistance l of different temperature - c o - efficient in parallel with the coil. The resistance m may be of nickel or copper, and the resistance l of manganin, constantan, or other material of negligible temperature coefficient. The resistance m may be high compared with the combined resistance of the coil f and resistance l. The temperature correction may be increased by the arrangement shown in Fig. 2, in which the circuit formed by the coil f and resistances l, m is shunted by a resistance l1 of manganin &c. and a resistance m1 of material of high temperature coefficient is connected in series. The compensation may similarly be further increased. The invention is applicable to determining the proportion of a gas such as carbonic acid by measuring its heat conductivity. In some cases, for example in measuring the methane content of air by measuring the heat conductivity, the series resistance m must be of zero or negative temperature coefficient, and the parallel resistance l of high positive temperature coefficient.

Title: Locomotive drafting
IPC: F23L17/00
Filed: 1942-08-26
Abstract: 558,247. Locomotive blast devices. KEILER, W. H. Aug. 26, 1942, No. 12024. [Class 51 (i)] Draft and back pressure regulating means for a smoke box comprises a number of independently mounted tips for the steampipe and automatic or manual means for selectively moving the tips into position. As shown the twin exhaust pipes 21, Fig. 1, can be fitted with tips A or B carried by rock shafts 31, 32 operated by pressure cylinders 43,' 44, or with tips C on shafts 34, 35 operated simultaneously by cylinders 45. The cylinders are controlled by electromagnetic valves 65, 66, 67 connected as shown to a prime mover 100. Under normal circumstances the tips A or B only are in use. A master switch 101 is provided which when moved to the contact 102 throws the switches 112, 107 into circuit the switch 112 being operated with the throttle lever and the switch 107 with the reversing lever. Movement of the master switch to the contact 103 throws the switch 121 into operation by means of which the boiler- or backpressure, led thereto by a pipe 122, effects the movement of an arm 120 to one of two contacts 123, 125. When the master switch is moved to the contact 105 the tips C, used in exceptional circumstances, are operated. To prevent the tips A, B fouling each other the forward movement of one is made to lag behind the retraction movement of the other by connecting the pressure pine of each cylinder to the far end of the other cylinder; the pistons, which are spring returned are thus moved to operative position by the fluid pressure less that of the return spring, and to the inoperative position by the sum of these pressures. As shown in Figs. 8 and 10, the tips A, B are of different heights so that the issuing streams strike the walls of the stacks 23 at a constant level, The steam pipes 21, Fig. 5, are fitted with renewable ends 24 secured thereto by screws 25 and having a bevelled fitting surface 28 ; the tips and mating ends of the members 24 have similar downwardly coned surfaces. By these means fouling of the joints by the blast is prevented. In other forms the rock shafts are operated by rack mechanism or are parallel with the steam pipe and have in addition an endwise movement. The control mechanism may be wholly pneumatic.

Title: Improvements in testing the inflation of pneumatic tyres on aircraft
IPC: G01L17/00
Filed: 1940-07-30
Abstract: 542,910. Pneumatic tyres. DUNLOP RUBBER CO., Ltd., and FLETCHER, H. R. July 30, 1940, No. 12338. [Class 144 (i)] A device for indicating deflation of tyres on aircraft during flight, and adapted to be positioned on the wheel support or aircraft structure, comprises a spring-loaded member arranged to contact the tread or side-wall of the tyre, the displacement of this member serving to operate the signalling means. As shown in Figs. 1 and 4, the device is mounted on a wheel support and comprises a cylinder 1 with a spring-loaded piston 7 the rod 6 of which is arranged to contact the tyre when the wheel is in its retracted (flight) position. Compressed air or other fluid from a supply 22 is fed to the space 19 above the piston through a pipe 21 and rotary valve 11. The valve is moved to admit the pressure fluid to the cylinder, or to exhaust the latter through a crossport 20 in the valve and a cylinder port 17, by a lever 14. In the form shown in Fig. 4, the lever 14 is adapted for manual operation. In Fig. 3, device is mounted on a fixed part of the structure, and the lever is connected by a link 26 to the wheelsupport 3. In this modification, the valve is automatically operated by movement of the wheelsupport between landing and flight positions. As shown in this Figure, the pipe line 21 is fitted with a cock 23 and pressure gauge 27. In operation, normal pressure in the tyre (registered on the gauge 27) the spring 8 holds the piston in its rearward position against the pressure in the pipe-line. On fall of pressure in the tyre, the piston 7 moves to uncover a vent port 9 in the cylinder wall thus operating the pipe-line to exhaust, the tyre-deflation being then shown on the gauge 27. As shown in Fig. 4, the valve 11 is provided with a port 18b for controlling the supply of pressure-fluid from the pipe 21 to a brake-operating pipe-line 24. Fig. 7 shows a modification in which movement of the piston rod 6, by reaction of the spring 8 on deflation of the tyre 2, brings a contact 37 across the terminals 35 of an electric circuit to operate a visible or audible signal.

Filed: 1925-05-14
Abstract: 254,846. British Thomson-Houston Co., Ltd., and Clinker, R. C. May 14, 1925. Measuring consumption of petrol with respect to mileage &c. of vehicles.-The rate of consumption of fuel by an engine is determined by measuring the distance travelled by the vehicle while a predetermined amount of fuel is being consumed. Fig. 9 shows diagrammatically an arrangement in which the main tank 11 fills an auxiliary reservoir 14 and feeds the carburettor pipe 12 when a valve 13 is open. On closure of a switch 51 the valve 13 is closed and the auxiliary reservoir 14 supplies the carburettor. At the same time the coil 52 is energized to attract an upwardly biassed detent 54, normally holding a wheel 35 driven according to the speed of the vehicle, releasing the wheel and allowing the pointer 26 to move over its scale and indicate miles per gallon. When a predetermined amount of fuel has been discharged from the reservoir 14, the float-controlled switch 20 engages the contacts 57 and the coil 56 is energized to apply a downwardly biassed detent 55 to the wheel 35 and stop it. On opening the switch 51 the valve 13 is opened and the parts restored to their previous positions. In the form shown in Figs. 5, 7 a shaft 28 driven proportionately to the vehicle speed drives a shaft 27 through gears 29, 30 which through a friction clutch 31<a> and gears 32, 33 drive a shaft 34 carrying a wheel 35 having a pin 36 adapted to engage a stop 37 on a piston 53 which is a tight fit in a cylinder 39 connected by a pipe 15 with the auxiliary chamber. A cord attached to the piston is passed over a pulley 40 to a counterweight 43. When the stop cock between the main tank and the auxiliary reservoir is open and the reservoir charged, the stop 37 lies against the pin 36. When the cock is closed and the auxiliary chamber supplies the carburettor, the chamber draws air from the cylinder 39 and the piston 38 moves down releasing the stop, the wheel 35 being free to rotate until engaged and held by a stop 45 on the counterweight, the pointer 26 indicating miles per gallon. Specifications 245,886, 245,896 and 247,692 are referred to.
