Title: Improvements in or relating to press-button switches
IPC: H01H13/74
Filed: 1967-08-24
Abstract: 1,201,658. Push-button switches. HOLZER PATENT A.G. 24 Aug., 1967 [26 Aug., 1966], No. 39108/67. Heading H1N. The housing for a plurality of push-buttons 5 comprises a U-shaped member 2 of insulating material riveted or welded to a plate 1, also of insulating material. Two insulating plates (6 and 11, Fig. 2, not shown) carried in the housing lie one on each side of the push-button shanks and support fixed contacts (8, Figs. 1 and 2, not shown). Spring-loaded bridging bars (9) carried on the push-button shanks cooperate with the fixed contacts (8). The insulating plate (6, Figs. 2 and 4, not shown) extends beyond plate 1 to limit the travel of buttons 5 by abutment with lips 14 thereon. Interlock slides 3 and 4 are carried by the member 2 and, as shown in Fig. 3, the first and third buttons 5 are prevented from being depressed until slide 4 is moved by operation of another button while the third (central) button is not latched by slide 3 and hence when operable is purely retractive and also does not release a previously operated button. The fifth (end) button protrudes more than the others such that when latched in (thereby releasing all the other buttons) it is aligned with the other buttons, and may be used as a main " OFF " switch.

Title: Water heater for coffee brewing apparatus
IPC: A47J31/46
Filed: 1971-08-23
Abstract: 1360673 Coffee-brewing apparatus BUNNO-MATIC CORP 23 Aug 1971 39417/71 Heading A4E [Also in Divisions B8 F4 and G1] A water heating apparatus for use in a coffee brewer 10 comprises a hot water tank 11 provided with a heating element 14 and a siphon tube 17, a cold water inlet pipe 24 provided with a dump valve 26, a cold water basin 27 having a cold water inlet line 28 provided with a supply valve 29, means for closing the dump valve 26 and opening the supply valve 29 to cause water to flow into the basin 27, and means for opening the dump valve 26 and closing the supply valve 29 when a predetermined quantity of cold water has flowed into the basin. The predetermined quantity of cold water in the basin flows into the hot water tank and displaces an equal quantity of hot water which flows through the siphon tube 17 to a spray head 18 for application to coffee 19 on a filter 20. In use, a start switch 50, Fig. 2, is closed to complete a circuit, and a solenoid 32 closes the dump valve 26, a solenoid 33 opens the supply valve 29, and a winding 45 closes contacts 43 of a relay 44. When switch 50 is released the solenoids 32, 33 and the winding 45 are still energized through closed contacts 41, 43. Cold water supplied through inlet line 28 fills the basin until a water level sensor 40 opens contacts 41 to de-energize solenoids 32, 33. The spring-loaded supply valve 29 subsequently closes and the spring-loaded dump valve 26 opens. The quantity of cold water supplied may be varied by adjusting the vertical position of the sensor 40. The tank 11 has a vent tube 16 and the heating element 14 is controlled by a thermostat 15. The water level sensor 40 is protected by baffles 30, 42. Light rays are reflected by a prism (60), Fig.3 (not shown), from a light source (58) to a light responsive device (57) which renders a SCR (56) conducting. The SCR ceases to conduct when the water level reaches the prism and the contacts 41, Fig.2, are effectively opened. A diode (61), Fig.3 (not shown), reduces chatter of the relay contacts 43.

Title: Method and apparatus for trapping ions in a magnetic field
IPC: H05H1/22
Filed: 1958-12-08
Abstract: 853,916. Nuclear fusion reactors ; discharge apparatus. UNITED STATES ATOMIC ENERGY COMMISSION. Dec. 8, 1958 [April 15, 1958], No. 39443/58. Classes 39(1) and 39(4). A device for establishing a body of trapped atomic ions in a predetermined zone in an evacuated chamber permeated by a containing magnetic field comprises means for generating and injecting a plurality of molecular ions in the form of a beam into the magnetic field in a direction normal to the field so that the molecular ions follow a curved path towards a high intensity arc discharge which generates atomic ions from the molecular ions, the atomic ions being trapped by the magnetic field in a circular trajectory smaller than the trajectory of the molecular ions. The principle of the invention is illustrated in Fig. 2. Molecular ions from a source 8 follow a curved path due to a magnetic field normal to the figure and pass through a high intensity arc 12, normal to the figure, where some of the molecular ions are converted to atomic ions which pursue the path 10. Unconverted molecular ions are collected at 15, and neutral particles produced in the arc escape along path 11 and may be utilized in particle accelerator or like apparatus. Fig. 4 shows a practical embodiment comprising an outer shell 36 and an inner shell 33 which can be evacuated through ports 37, 38 and 41, 42, the pressure preferably being reduced to 10<SP>-7</SP> mm. in the inner shell and 10<SP>-6</SP> mm. in the outer shell. Arc electrodes 27, 28 project trhough the walls of the outer shell into baffles 29, 30 provided on the inner shell. An axial magnetic field is provided by pole-pieces (not shown) and a mirror field is provided by coils 31, 32 to prevent atomic ions migrating in an axial direction. An ion source 491 may be of the mass spectrometer type and may inject deuterium ions with an energy of 300 Kev. through the outer shell and through an opening (not shown) in the inner shell into the path of the arc.
