Filed: 1974-06-27
Abstract: 1464889 Ice-making KING-SEELEY THERMOS CO 27 June 1974 28639/74 Heading F4H In an ice making apparatus comprising a cylindrical housing 12 containing a rotatable auger 14 for conveying ice formed on the internal wall of the housing to an ice compacting chamber 42, the ice is discharged from the chamber 42 through a spout 54 formed with a passage 84 extending tangentially to the chamber. An ice removing blade 100 projects into the chainber 42 for causing ice to move into the discharge passage 84. As shown, the blade 100 is defined by a planar surface 108 and a cylindrical surface 102 which intersect at a position coincident with the downstream side of the discharge passage, whereby the blade is entirely out of registry with the flow path from the chamber 42 to the outlet end of the discharge passage. The spout is secured in position over an outlet opening in the housing 12 by a retainer plate 70 and bolts 80, 82.

Title: An Automatic Switching Device for Radio Amplification and similar Systems
Inventor: SUNDIN ANDERS T
IPC: H04M11/08
Filed: 1952-11-14
Abstract: 721,653. Loud-speaker systems; sound reproducing circuits. SUNDIN, A. T., and NILSSON, H. N. Nov. 14, 1952 [Nov. 19, 1951], No. 28741/52. Class 40 (4). In a system in which signals from a first source normally pass from a first input circuit of the system to a load circuit, e.g. a loudspeaker, on the application of signals from a second source to a second input circuit the latter signals are amplified and a portion thereof is rectified, the rectified voltage, if greater than a threshold value, serving to render an amplifier in the first signal path non-conducting and to increase the gain of the amplifier in the second signal path, the remaining portion of the output of the lastmentioned amplifier being applied to a final amplifier common to both signal paths and thence to the load circuit, so that presence of the second signals suppresses the first signals and only the second signals appear in the load circuit. As described, the first signals, which are audio-frequency currents from the A.F. stage of a radio receiver, are applied at 8 and are normally amplified in amplifier 9 and applied via the final amplifier 10 to the load (not shown) which may be a loud-speaker in a public service vehicle. If it is desired to interrupt the radio programme with an announcement, the attendant speaks into microphone 11. The speech currents are amplified at 12 and 13, part of the output being rectified in diode 14 provided the peak voltage exceeds that across the cathode resistor 15. The voltage appearing across resistor 16 is smoothed and applied to bias back the amplifier 9, thus reducing the gain of that amplifier and hence the voltage across 15. The gain of 12 is therefore increased and eventually valve 9 is cut off and the gain of 12 is considerably increased. The output of amplifier 13 is fed via final amplifier 10 to the load.

[Class 100 (iii).] Single-type composing and casting machines ; moulds.-Leads, rules, and other furniture are produced by incremental or additive casting in determinate lengths by intermittently moving the cast element a certain distance out of the mould during a predetermined number of casts, and, after the final cast, moving the element through a greater distance, so that the incoming metal does not fuse with the previous cast. The mould A, shown in plan in Fig. 4, is of similar construction to that described in Specification 7202<*>/15, [Class 100 (iii), Type making &c.], and is provided with an ejecting blade B, the open end of the mould being closed by the previously cast element. The side walls may have inwardly extending projections to produce elements of I or H shape in cross section. The forward movement of the blade is limited by a movable stop D, which is withdrawn after a predetermined number of casts, so that the blade makes a longer stroke, and carries the cast strip to a greater distance beyond the molten-metal inlet, so that a non-fusing cast is made at the next operation. The stop D is operated by a timing device, such as that described in Specification 316,346, [Class 100 (iii), Type making &c.], and comprising an angularly movable abutment E<6>, Fig. 9, which is advanced step by step by ratchet mechanism from a position in contact with an adjustable stop E<1> until it operates a trip-lever E<7>. The ratchet mechanism is thereby caused to make a longer stroke, and to operate a bar D<3> connected to the stop D. The forward movement of the blade for non-fusing casts is arrested by an adjustable stepped stop.
