Filed: 1938-11-30
Abstract: 522,094. Automatic exchange system. POLLAK, J. E. (Associated Telephone & Telegraph Co.). Nov. 30, 1938, No. 28282/39. Divided out of 516,348 and 516,408. Drawings to Specification. [Class 40 (iv)] The system described in Specification 516,348 is provided with arrangements for restricting the service from certain substations. The restriction may be effected by grounding the mid-point of the ringer windings and in the case of an hotel, for example the grounding is controlled by the proprietor. The ground prevents the operation of one of the loop feed-relays at the register-translator and this in conjunction with the operation of a relay when a first digit " O " is dialled brings about the release of the registertranslator. Some calls having a first digit " O "  may however be permitted by arranging that the relay which is operated to bring about the release of the register-translator is subsequently shunted down by a circuit over the charge assessing switch (TD3). set in accordance with the setting of two bi-directional switches (TD1, TD2) which respond to the zone and exchange digits respectively. These arrangements are described with reference to Figure 27 (not shown) which does not appear in the abovementioned Specification. Specification 516,409 also is referred to.

Title: Improvements in means for controlling the fuel supply in two-stroke internal combustion engines
IPC: F02D1/00
Filed: 1939-10-20
Abstract: 542,956. Regulating. AKTIEBOLAGET ATLAS DIESEL, and CAMNER, H. G. Oct. 20, 1939, No. 28364. [Class 7 (vi)] [Also in Group XXIX] In means for controlling the fuel supply of a two-stroke engine by causing the scavenging- air pressure to act on a piston or membrane connected to the fuel control, the effect of changes in scavenging-air pressure brought about by variations in the exhaust backpressure when the engine torque changes is counter-acted by providing a further pressure acting on the piston &c. in accordance with the torque of the engine. Fig. 2 shows a fuel pump 1 with its control rod 2 connected by a lever 3 to a piston 7 acted on by the scavenging- air admitted to the chamber 8, this chamber being also connected by a pipe 14 to an atmospheric outlet 15 controlled by a valve 13, also connected to the lever 3. As the torque of the engine decreases, the valve 13 becomes more closed and maintains the pressure in the chamber 8. Initial adjustments may be effected by varying an eccentric fulcrum 4 of the lever 3, or the tension of a spring 12 acting on the piston 7. The chamber 10 at the other side of the piston may be connected to a point in front of a throttle in the exhaust pipe. A dash-pot 16 may be provided in connection with the valve 13 or the piston 7, for damping out oscillations. In modifications, the escape to atmosphere from the chamber 8 may be controlled by the piston 7, or be hand-actuated. In another form, the outlet from the chamber 8 controlled by the valve 13 may lead to a further piston which adjusts a throttle in the discharge of the scavenging-pump ; or this throttle may be hand-actuated.

Title: Automatic device for taking samples of radio active solutions
IPC: G21F7/06
Filed: 1959-08-20
Abstract: 869,249. Sampling liquids. COMMISSARIAT A L'ENERGIE ATOMIQUE. Aug. 20, 1959 [Aug. 26, 1958], No. 28491/59. Class 106(5) [Also in Group XL(a)]. An automatic device for taking samples of radioactive solution comprises a vessel 1 containing the-solution and situated within a lead enclosure 19. An enclosure 2 connected to the vessel 1 through a valve 18 has a feeding conduit 4 terminated by a hypodermic needle 5' penetrating the rubber stopper of a sample bottle 3. The bottle 3 is shielded by a lead container 20 - which, initially, is mounted upside down with its lid 21 on a carriage 22, the container being raised by a lifting device 23 so that its lid may be removed and the container lowered on to the needle. The enclosure 2 is connected through a vessel 9 to an electromagnetic valve 10 controlling the evacuation of the enclosure and to an electromagnetic valve 11 which places the enclosure open to the atmosphere. The enclosure 2, conduit 4 and vessel 9 are of very low carbon stainless steel, the conduit 4 being insulated from the enclosure by a plug 6, electric terminals A; B being connected 'to the conduit and enclosure through leads 16, 17. To obtain a sample; a push button in an electric relay-system (Fig. 2, not shown) is pressed whereby atmospheric valve 11 is closed by its operating coil 13, and at the end of its closing movement a switch 15 is closed to open valve 10 whereby the enclosure 2 and bottle 3 are evacuated. Thus liquid is sucked up from the vessel 1 into the conduit 4 and a circuit is completed by the liquid between terminals A, B so that the coil 12 of valve 10 is de-energised and valve 10 closes. The end of the closing movement of valve 10 causes, through switch 14, opening of valve 11, and the liquid which has entered the conduit 4 is forced into the bottle 3. The bottle 3 may now be removed and further samples collected by repeating the procedure. A probe 7 makes contact with the liquid to establish connection between terminals A, B and functions as a safety device in the event of failure of the contact made with conduit 4.
