Cream is supplied to the moulds as they reach a position beneath the discharge tubes 24a of a reciprocating-piston filling device 22, and sticks are inserted into the partially frozen cream by means 23 carried by a radial arm 29 adjustably mounted on the pillar 12 of the machine and including a vertically-reciprocated piston operated by an electric motor 59, the current supply to which is controlled by a commutator 55 having a single conducting segment 56 and mounted on a shaft 54 driven through reduction gear from an electric motor 25. The annular vessel is rotated through a toothed-wheel 13, integral with the vessel, and a pawl 14 by an eccentric 53 on the shaft 54. After passing through the freezing and thawing zones, the moulds reach a position beneath a device by which the sticks with the frozen cream adhering thereto are withdrawn froin the moulds. The withdrawal device is carried by a radial arm 46 adjustably mounted on the pillar and comprises a transverse bar 38 carrying stick-engaging tongs 39, Fig. 9, at its opposite ends and secured to the upper end of a shaft 31, Fig. 7, adapted to be reciprocated through a connecting-rod 33 from a shaft driven through a telescopic shaft 47 and universal joints from the shaft 54. The shaft 31 is partially rotatable by a set-screw 37 engaging in a groove 36 formed in the shaft. When the moulds reach the device, the shaft is arranged to move downwards and force the tongs over the sticks and then upwards to remove the portions of frozen cream. The shaft is then partially rotated to position the portions over a discharge plate or conveyer 68, at which stage the shaft again moves downwards and the tongs are released from the sticks by a spring-urged lever 43 engaged with eyes 64 formed on the tongs and abutting against a stop 45. The withdrawal device may be used to dip the portions of ice-cream into a bath of chocolate before depositing them on the plate 67.

Abstract: 1378251 Measuring r.m.s. values WESTON INSTRUMENTS Inc 12 Jan 1972 [15 Jan 1971]  1362/72 Heading G1U The r.m.s. value of an input signal I, applied to a'terminal 22, is evaluated by an automatic balancing loop in which the difference I-If, where If is a feedback signal, and the sum I + If, are applied respectively from two summing junctions 28, 30 via amplifiers 18, 20, to the two inputs 21, 23 of a multiplier 12, and the output of the multiplier, which will equal I<SP>2</SP> - If<SP>2</SP>, is integrated 14, to produce the feedback signal If, which signal is also available as an output signal on a terminal 56. In the equilibrium condition, the output of the integrator will be static and therefore the integral of the input then applied to it will be zero. That is, (I<SP>2</SP>-If<SP>2</SP>) dt=0, and therefore, since If is constant, If is the r.m.s. value of the input I. (For Figure see next page)

[Also in Group XXIX] In means for controlling the supply of liquid fuel to a jet-propelled aerial body through a liquid-operated servo-mechanism, the fuel control member is operatively associated with a hydraulic buffering device controlled by a freely movable member, such as, the shuttle valve 8, responsive to the acceleration or deceleration of the aerial body. In Fig. 1 a fuel throttle a unitary with a spring-loaded servo-piston e controls the flow through a seating b between an inlet c and an outlet d. The servo-cylinder g is supplied through a restricted orifice h and is vented under the control of a valve j. The valve j is carried by a lever k operated by a diaphragm m subject to the pressure drop across an orifice o. The hydraulic buffering device comprises plungers p, q, extending from opposite sides of the throttle a and operating in cylinders r, s to which liquid is admitted through a passage t and restricted orifices at the ends of the plungers. The cylinders are connected by passages v, w to ports 2. 3 differentially controlled by the shuttle valve 8 which moves relative to the aerial body when the latter accelerates or decelerates. The ports 2, 3 communicate with a common outlet 7. In a modification; Fig. 2, the fuel throttle a is connected to a buffer piston 26 bv a rod 27. Opposite sides of the piston 26 are fed with liquid from the inlet c through a passage 30 and restricted orifices 31. Outlet passages 32. 33 from opposite sides of the piston 26 lead to ports 34, 35 controlled by a shuttle valve 8 responsive to acceleration or deceleration of the aerial body. The throttle a is loaded by a spring f and is operated by, the servo-piston e under the control of a vent valve j. The valve is operated through a lever k by an elastic evacuated capsule 11a subject to atmospheric pressure or to blower delivery pressure. The pressure dron across the throttle a acts through passages 12, 13 on a spring-loaded diaphragm 14 which operates the vent valve 18 of a servomotor 20 controlling the output of a variable delivery pump or otherwise regulating the fuel supply to the engine. According to the Provisional Specification, the freely slidable shuttle may be replaced by freely slidable sleeves co-operating with radial ports in the plungers associated with the throttle. The control of the fuel supply to a ram jet-propelled missile is referred to.

Abstract: 963,137. Colour television. FERNSEH G.m.b.H. Jan. 13, 1961 [Jan. 16, 1960], No. 1512/61. Heading H4F. N.T.S.C.-type equipment is tested with the aid of a test signal, Fig. 6g, consisting of bursts of subcarrier oscillation which occur in sequence at the " I," " Q " and synchronizing phases, the bursts each being located on a pedestal and each being preceded by a video frequency pulse of predetermined amplitude. The signal, after passage through the equipment, is applied to a cathode-ray tube vectorscope in which the subcarrier bursts and video frequency pulses are separated, the subcarrier bursts being applied via quadrature synchronous detectors to the X and Y deflection plates of the tube so as to trace the " I," " Q " and " b " (synchronizing) vectors, whilst the video frequency pulses are applied to only the Y deflection plates so as to trace (due to the finite rise time) a line Y representing the gain of the luminance channel in the equipment under test. A generator for the test signal together with the vectorscope is described in block form, Fig. 5 (not shown). The equipment is driven from the line synchronizing pulses, the groups of three (" I," " Q " and synchronizing) subcarrier bursts and video frequency pulses recurring at line frequency. Each burst is produced by modulating a subcarrier oscillation of appropriate phase with a wave produced by clipping a sawtooth signal. The method of setting up and calibrating the vectorscope is described.
