Title: A polyphase two-layer wave winding for barwound electromagnetic pumps and conveyor troughs
IPC: H02K44/06
Filed: 1969-09-24
Abstract: 1,236,119. Winding layouts for dynamoelectric machines. AEG-ELOTHERM G.m.b.H. 24 Sept., 1969 [20 Feb., 1969], No. 47072/69. Heading H2A. A polyphase, two-layer, bar wave winding for the linear stator of, for example, an electromagnetic pump or a conveyer trough has a halfwound pole at each end and from one terminal U, Fig. 3, which shows one phase only, alternates from pole to pole between the top and bottom layers, returning at the end pole 6 by forming a loop and changing from one layer to the other at 12, and then proceeding back along the stator so that each slot, other than those of the end poles, contains one bar of the forwardgoing and one bar of the returning portions of the winding. As shown, the end 9 of the double wave winding passes through a return lap 10 into a second double wave winding similar to the first and which terminates at X. In this arrangement the end bars of the winding at the first pole 7 change from one layer to the other similarly to the bars at the point 12 but in an alternative arrangement, Fig. 5 (not shown), this transition may be effected outside the slots by an end connection (10) in the case of the return lap. This enables two windings such as a four-pole winding shown at 12 in Fig. 7c and a three-pole winding 13 to be combined so that the terminals U, X are not at the end of the stator. Individually, the two windings have terminal arrangements one of which is a mirrorimage of the other and in the combination shown, the end of winding 13 is connected to the beginning of winding 12 at 8. A tapping 9 may be provided at the point 8 so that by applying current between U and 8 or between X and 8 winding 13 or winding 12 alone may be energized when the pump or trough is to deliver in-metered quantities.

Abstract: 1,216,138. Valves. HILLS-MeCANNA CO. 9 Oct., 1968, No. 47886/68. Heading F2N. In a rotary ball valve 10, sealing of the flow passages 16, and 18 with respect to a chamber 14, which chamber accommodates the rotary ball 26, is achieved by means of two identical passage encircling structures each of which comprises a resilient seat 70, a metal ring 72 encircling the seat, and a seat support 86. The seat support is sealed with respect to the valve housing 12 by a seal 92, is biased towards the ball by a spring 98, and has its seat-engaging surface 82 curved, the radius of curvature of which surface is identical to the same of the ball 26. The ball and seat support-engaging surfaces of seat 70, present concave surfaces 78 and 80 respectively, the radii of curvature of which surfaces likewise correspond to those of the support and ball, the combined arrangement permitting each seat to move transversely with respect to the flow passage axis in the event of the ball undergoing similarly directioned movement. The ball operating shaft 32 is retained within bearings 36 and 38, and is sealed with respect to a bonnet 22 by two seals 46 and 52, the bonnet being removably retained within a housing bore 24 such that the valve component parts may be removed through the bore 24, and the seals 46 and 52 being compressible into tighter engagement with the shaft 32 by screwing of a nut 58, the nut acting on a washer 60 which encircles the stem in a non-rotatable, axially movable manner, and further coacts with an abutment 62 to limit the rotation of the ball. In an alternative embodiment, Fig. 4, not shown, spring 98 is replaced by a spring which in radial section has a central U-shaped portion and two lateral limbs, the limbs being welded to the bore 16 and support 86.

Title: Automatic control system for cameras
IPC: G03B17/42
Filed: 1963-12-06
Abstract: 1,58,088. Automatically operated cameras. EUROPEAN ATOMIC ENERGY COMMUNITY (EURATOM). Dec. 6, 1963 [Dec. 7, 1962], No.48336/63. Heading G2A. Knob 2 of camera 1 is rotated, to advance the film and set the shutter, by an automatic mechanism which then also presses button 3 to release the shutter and make the photographic exposure. The automatic operating mechanism comprises two annular members 4 and 7, which may be of a plastics material. Member 4 fits round knob 2, and is secured thereto by a screw 5. Member 7 has a shaft 12 which passes through a hole in a supporting plate 13 to a reversible electric motor 11. Member 4 rests inside member 7, which has a lug 8 near its edge. As member 7 is driven by the motor in the direction f, lug 8 engages against a lug 6 on member 4, thus rotating that also and hence knob 2, so setting the shutter and advancing the film. Motor 11 is then reversed to return member 7 to its original position, this reverse rotation having no effect on member 4. The top rim of member 7 is shaped as a cam edge 9 having a raised ramp portion 10. If member 7 is now turned sufficiently far (i.e. farther than the previous rotation), this ramp portion will engage the button 3, so releasing the shutter, which remains open until ramp 10 rides clear of the button. At the same time, knob 2, and hence member 4, are released to return to their original position. The arrangement is suitable for taking successive pictures of an oscillograph screen, the instrument being secured to the supporting frame 13, 14. Fig. 2 (not shown) illustrates the whole apparatus assembled in the operative position. The motor 11 may be programmed to make a series of exposures automatically, and also to control more than one camera.

Abstract: 1451213 Touch responsive switching circuit TEXAS INSTRUMENTS Inc 18 Oct 1973 [12 Feb 1973] 48657/73 Heading G1N [Also in Division H3] In a plural channel interlocked semi-conductor switch including an electric current source CCS 1 connected in series with parallel connected switch devices SW1-SW4 of the channels, each switch device includes a transistor Q1 of opposite conductivity type to two other transistors Q2 and Q3, current flow through a current flow-path including base-emitter of Ql, the collector emitter of Q2 and a direct current impedance R2 establishes a predetermined holding voltage between energization lines VS, VR to enable that switch device to be latched in an ON condition. The transistor Q3 is responsive to a selection signal applied to its base to lower the voltage between the energization lines below the holding value to turn off any switch device which was previously on, and a current flow through a further current path including the baseemitters of Q1 and Q2 and the collector-emitter of Q3 forward biases the base-emitter of Q1 and Q2 of the selected switch to switch current flow from the current source CCS 1 through the current flowpath Q1, R2, Q2 of the selected switch device to latch that switch device in the ON condition upon removal of the selection signal at CE. As shown in Fig. 2 the selected switch device is energized by touching contact SE of an input amplifier IA1 which includes a capacitor Cl providing a delay in turn off of the transistor Q3. The output from the selected switch SW1 turns on transistors Q7-Q12 to provide outputs at A and B of an output circuit OS1. A diode Dl maintains the holding current constant with temperature changes to prevent a conductive switch being switched back to the non-conductive state. In a TV channel selector Fig. 3, a digital section circuit DSW is as shown in Fig. 2. The output A of a channel selected by touching a contact CP turns transistors Q13 and Q15 on and a transistor Q14 off of an associated channel circuit AS1-AS4 to couple a turning voltage set by a potentiometer VR1-VR4 via a transistor Q16 to varactor tuning diodes of tuners. The output B of the selected channel is connected by a band selector switch SWA-SWD to supply power to a selected tuner BTI, BTII, BTIII provided for three different frequency bands, such as two VHF bands and a UHF band. The power supply RPS and constant current sources CCS1-CCS3 may be constructed using transistors and resistors and the circuits can be in integrated form.
