Title: Improvements in or relating to pyrimidine derivatives
Filed: 1954-04-21
Abstract: The invention comprises pyrimidine derivatives of the formula <FORM:0755997/IV(a)/1> in which R is hydrogen or acyl, and a process for preparing them by the action of guanidine or a salt thereof on ethyl 2-(31 : 41-dichlorophenyl)-3-oxo-pentanoate in presence of oleum having 15-40 (preferably 20) per cent free SO3, to form the corresponding 4-hydroxy compound, and, with or without acylating the NH2, replacing the hydroxy group by chlorine, e.g. with POCl3.  In an example, guanidine carbonate reacts with the above pentanoate esters to give 2 - amino - 4 - hydroxy - 5 - (31 : 41 - dichlorophenyl) - 6 - ethylpyrimidine, which may be acetylated with acetic anhydride, converted with POCl3 to the above 4-chloroacetylaminopyrimidine and hydrolysed to the 2-aminocompound.  Ethyl 2-(31 : 41-dichlorophenyl) 3-oxo-pentanoate is obtained by the action of ethanol on 2-(31 : 41-dichlorophenyl)-3-oxo-pentanonitrile, obtained from ethyl propionate with 3 : 4 - dichlorobenzylcyanide. Specification 748,358 is referred to.

Title: Improvements in or relating to conveyor systems
Inventor: BARTHALON MAURICE
IPC: B60V3/04
Filed: 1969-03-06
Abstract: 1,248,808. Elevated railways; air cushion vehicles. M. BARTHALON. 6 March, 1969 [8 March, 1968], No. 11879/69. Headings B7K and B7L. In a transport system, transport containers or vehicles are picked up by a carrier, which is supported in an elevated track so as to glide substantially frictionlessly therealong. The carrier is supported by magnetic levitation or air pressure. In an example of the latter, Fig. 1, electric motors 13 drive fans 12 to provide suction support for carrier 1, in track 2, and to attract container 20 to the carrier. The container is further secured by electromagnetically operated hooks 25. At unloading stations, collectors 29 contact conductors 30, to release hooks 25 and open electromagnetic valve 23, thus breaking the vacuum and releasing the container 20. The suction above the carrier prevents it from rubbing against the walls of the track, while it is propelled therealong by wheels 4, driven by electric motors. Adjacent carriers may be linked together. An automatic pick-up arrangement (Fig. 4, not shown) is described. For transferring the container from one track 2 to another, a ground track (55, Fig. 6, not shown) is provided. Fans (53) support a carrier (50) on an air cushion enclosed in the track (55). The transfer between tracks 2 and (55) may be effected automatically according to the setting of a switch (Fig. 7, not shown). In a modification, a carrier (95, Fig. 10, not shown), similar to the carrier 1, is propelled by a linear induction motor (96) while supporting an electrically driven car (102). Car 102a is propelled up ramp 105, in response to photocell 109, at a remotely controlled speed and united with carrier 95a. The passenger compartment of an aircraft may be arranged to travel along a track 2. Alternatively, fans 201, for evacuating the space above the carriers 1, are mounted on the track. The spaces between the carriers are sealed by flexible connectors 205 and the assembly is propelled by linear induction motors (212, 213). The flanges of the track underlying the carrier can, in an alternative form, support an air cushion for the carrier. The air cushion may either be generated in the track (Fig. 19, not shown) or in the carrier (Fig. 20, not shown). In a form, in which the carrier 80 is supported and propelled by electromagnetic induction in a tunnel 70, an electromagnet 84 secures container 89 and is energized by collectors 88 and conductors 87. The conductors 87 are interrupted at unloading stations.

Title: Improvements relating to thermionic switching systems
IPC: G01S7/36
Filed: 1944-06-26
Abstract: 580,575. Wireless signalling ; valve relay circuits. FERRANTI, Ltd., and THOMAS, G. I. June 26, 1944, No. 12149. [Class 40 (v)] A thermionic switching device, actuated only upon the simultaneous application of at least two control signals, comprises at least two thermionic valves which have a common anode load impedance formed by a double branch circuit, one branch comprising a resistance and the other a series connection of a diode valve and a condenser-shunted resistance. This circuit, on the simultaneous cessation of conduction of the valves due to the application of the control signals, causes an output signal to be emitted from the device. Fig. 2 shows a form of the switch, the anodes 3, 4 of the pentode valves 1, 2 are connected together and to a trigger device through a condenser 5. The anodes are connected to the H.T. supply through a branched circuit comprising a resistance 6 as one branch, and a series connection of a diode valve 7 and a condenser-shunted resistance 8, 9, as the other branch. The control grids 11, 12 receive the respective control signals. The time constant of the condenser 8 and the resistance 9 is preferably long compared to the duration of the signal pulses, resistance 9 is smaller than resistance 6, and the diode valve 7 operates so that its D.C. resistance is small. If a pulse is picked up in one only of the receiving channels, one of the pentodes is cut off and the potential of the anodes 3, 4 changes only slightly and so the transmitter remains cut off. On the simultaneous reception of a pulse in both receiving channels, both valves 1, 2 are cut off and hence the anode current is zero and the anodes 3, 4 attain the potential of the H.T. supply. In consequence, a positive pulse is applied through the condenser 5 to a trigger device which may start up a transmitter for returning a recognition signal from an aircraft. The several control signals may be in the form of carrier pulses differing in wavelength (Fig. 1, not shown).

Title: Improvements in or relating to a windshield wiper
IPC: B60S1/12
Filed: 1960-04-06
Abstract: 948,142. Windscreen wiper motors. TRICO PRODUCTS CORPORATION. April 6, 1960 [April 6, 1959], No. 12232/60. Heading A4F. [Also in Division F1] An hydraulic windscreen wiper motor 12 has a piston 61, Fig 2, reciprocated by hydraulic pressure to oscillate a shaft 55 coupled to the wiper mechanism, the hydraulic pressure being reversed at the end of each piston stroke by a shuttle valve 91, and includes means such as valves 75, 75<SP>1</SP> for gradually restricting the flow of hydraulic fluid into and out of the motor towards the end of a piston stroke and gradually easing such flow from the beginning of a piston stroke. Thus the piston speed is reduced towards the end of each stroke and increased at the beginning thereof. The hydraulic fluid is supplied to the motor 12 by a pump 22, Fig. 1, from a reservoir 24 through conduits 25, 26, flow regulating valve 30, and conduit 33. The valve 30 permits a variable rate of flow of hydraulic fluid at constant pressure to the motor 12. The hydraulic fluid is admitted to the shuttle valve 91 on the actuation of a control valve 37 by a Bowden cable 21. In the operating condition illustrated in Fig. 2 the fluid passes from the valve 37 through conduits 88, 89, the shuttle valve housing, conduits 98, 99, the control valve housing, and conduits 100, 101 to the duct 76 containing the valve 75, and thence into the motor chamber to the left of the piston 61. The liquid to the right of the piston is exhausted to the reservoir 24 through the duct 76<SP>1</SP> containing the valve 75<SP>1</SP>. As the piston 61 thus moves counterclockwise a gear 65 on the shaft 55 rotates pinions 67, 67<SP>1</SP> on the shafts carrying the valves 75, 75<SP>1</SP> so that the latter are rotated to permit an increased flow of hydraulic fluid until the mid position of the piston 61 is reached when the flow is decreased. When the piston reaches the end of a stroke a lug 104 (not shown) on the pinion 65 actuates a pilot valve 105 (not shown) to cause the hydraulic fluid to move the shuttle member of the valve 91, and thereby reverse the fluid flow into and out of the motor chamber and change the direction of movement of the piston 61. Specification 872,559 is referred to.
