Title: Apparatus for decorating filled chocolates,pastry,and the like
IPC: A23G3/28
Filed: 1961-12-12
Abstract: 971,758. Coating confectionery. BAKER PERKINS Ltd. Dec. 12, 1961 [Dec. 16, 1960], No. 44380/61. Heading A2A. Chocolates, pastry, &c. are decorated by material ejected through inter-changeable nozzles 2 screwed into a supply tube 1 suspended by rods 21, 22, 23, 24 for decorating movements in a generally horizontal plane. The decorating material is fed into tube 1 under pressure through flexible pipe 14 and excess material passes out through flexible pipe 15 to be reheated and recirculated. Items to be decorated may be on a stationary table or on a conveyer belt. The nozzle apertures are opened and closed if desired during actual ejection, by needles 3 arranged as shown in Fig 1 or as in Fig. 3. In the first case flanges 5 on the needles are engaged by forked levers 7 on a shaft 13 which is turned to lift the needles against springs 6 by pulling on a Bowden cable 9 attached to an external arm 8, the upper ends of the needles 3 sliding into recess guides formed by caps 4 over apertures in the tube walls. In Fig 3 the needles are shorter and have enlarged upper ends 45 nestling in recesses 46 in a bar 49 along a shaft 47 which is turned similarly to shaft 13 (Fig. 1) against a spring 50. The nozzle actuating mechanism may be controlled mannually or automatically, and movements of the nozzle assembly may be similarly controlled. An automatic control of the nozzle assembly is shown in plan in Fig. 7 and elevation in Fig. 9. Movements of the nozzle supply tube 1 are restricted by a parallel linkage 27 so that is always remains parallel to itself. The supply tube 1 is suspended by four ball-ended rods 21-24. Electric motor 28 drives crank arm 31 whereby connecting rod 32, universally pivoted at 34, describes a conical motion. This motion is imparted to bearing 35, which may be held fast by clamping screw 40 in which case the nozzle tube assembly describes a circular translatory movement in a horizontal plane. If the clamping screw 40 is slackened, the circular movement becomes a reciprocating translatory movement. Further variations may be obtained by clamping the end of lever 38 in various positions in segment 39, and by raising or lowering the bearing point 24 on connecting rod 32, for which purpose the bearing is slidable on rod 32 and is carried by bush 37 which may be screwed up or down on bush 36 as shown by arrow A.

Title: Improvements relating to electronic counters
Inventor: MARENBACH KLAUS
IPC: H03K23/66
Filed: 1961-12-13
Abstract: 999,789. Control of motors. LICENTIA PATENT-VERWALTUNGS G.m.b.H. Dec. 13, 1961, No. 44648/61. Heading H2J. [Also in Division G4] In counting to a predetermined number the number is set up on scales so as simultaneously to set the counter to the complement of the number, a signal being issued when the counter is full. The predetermined number is set up on selectors 9-13 and a source 8, manually or automatically operated, supplies a pulse to set the several stages of a dekatron counter to the 9's complement of the number. A correcting pulse transmitter 7 adds 1 to provide the true complement. Pulses from a source 6 then advance the counter until all stages are simultaneously at 0 when AND gate 16 operates a relay 18. The relay 18 may automatically reset the device to cause repeated operation. The invention is applicable to measuring, controlling or regulation of speeds of rotation, positional control of machine tool elements, batch sorting and conveying. As applied to movements it is desirable that the movement shall be rapid until the desired point is approached after which a slower speed should be adopted. As applied to a machine tool or travelling cage in hoisting gear, the source 6 is operated by photo-electric or magnetic means to issue a pulse for every 1/100 mm. movement. Gauged selectors 14, 15 are set so that when the moving element is between 5 and 14 mm. of the desired point a relay 21 operates to switch the movement from high speed to creep speed.

Title: Amplifier circuit
IPC: H04H20/88
Filed: 1976-10-28
Abstract: 1528060 Transistor amplifiers MOTOROLA Inc 28 Oct 1976 [17 Nov 1975] 44846/76 Heading H3T An amplifier 81, more particularly for following an A.F. stereo decoder, comprises a common base transistor 96 to the emitter of which the input signal is directly applied and having its collector coupled to a current inverter stage 100, and a stage 106 coupled to the output of 100 and having D.C. negative feedback to the base of transistor 96. Aims of the circuit are to provide low distortion, high slew rate and a high output impedance at terminal 82 to which a de-emphasis network 84, 86 may be attached. A diode-connected transistor 92 predistorts the input signal to compensate for distortion due to the non-linearity of the base-emitter junction of transistor 96. Dual collector transistor 100, connected to act as a current mirror, may provide current gain in order to produce high positive slew rate; transistor 100 may be replaced by an ordinary transistor in combination with a diode. Common collector transistor 106 provides negative feedback from its collector to the base of 96, to stabilize bias levels, to reduce distortion and to increase the output impedance of stage 106. Another negative feedback path is provided through transistor 118 to the base of 106. A transistor 120, connected to act as a capacitor, is for correcting the frequency response, and rapid discharge of this capacitor, to ensure high negative slew rate, is provided by transistor 118. An emitterfollower output stage 85 is provided to act as a buffer for the de-emphasis network 84, 86, and the non-linearity of the base-emitter junction of emitter-follower transistor 110 is compensated by the transistor 118 feedback path. An integrated circuit (20), Fig. 1 (not shown), includes two amplifiers according to Fig. 2 for left (68) and right (80) channels respectively. It further includes a decoder (21) comprising an emitter coupled pair (30, 32) to one base of which the composite stereo signal is supplied. Each collector of transistors (30, 32) is connected to the emitters of a further emitter coupled pair (40, 42 and 44, 46, respectively), the bases of these transistors being supplied in push-pull with the sub-carrier, typically 38 kHz. Transistors (40, 44) and (42, 46) are connected as collector coupled pairs to the respective amplifiers (68, 80). With sub-carrier signals of alternate polarities the stereo signal is gated into either the right or the left channel amplifier.

Abstract: 1322825 Attenuators TEKTRONIX Inc 28 Sept 1971 [30 Oct 1970] 45081/71 Heading HIS [Also in Division H3] A continuously variable attenuator for terminating a transmission line of characteristic impedance Zo comprises, at its input, conductor pair 44, 46 having the same characteristic impedance, Zo, as does stretcher section 54, 46, 48, 50 connecting the input to a movable lossy transmission line having characteristic impedance Zo including an attenuation reistance 26 of resistance R per unit length wiped by fixed output contact 40, a set, n per unit length, of equal valued,  shunt resistors 30, and a terminating resistance 32 of value Zo. The input, resp. output, impedances are thus Zo, Zo/ 2 , independent of the wiper setting. In Fig. 2, (not shown), the lossy transmission line is fixed, the wiper 40 being movable. The attenuator may be used with its input and output (correspondingly its input and output impedances), interchanged. Construction.-Fig. 4. An aluminium oxide ceramic rotor plate 58 rotatable between stops (not shown) by shaft 62 has coated upon it the attentuation resistance 64 (corresponding to, in Fig. 3, 26) engaged by spring contact 76 (40), conductor strip 78 providing the output, shunt and terminating resistor 68 (30) 70 (32) and a conductive layer 66 (28) being grounded via layer 74 Fig. 5 (not shown), lining the centre hole connected to layer (72), wiper (92) and layer (90) on aluminium oxide ceramic stator plate 60. Arcuate strip 80 (36) couples the resistance 64 to strip 82 (44) providing the input, and is pressed into engagement with strip 80 by an acetal resin plastics or aluminium oxide ceramic contact pressure plate (86, Fig. 5) with an arcuate notch (88) enclosing strip 80. The constructons of Figs. 3 and 4 ensure that the input-output distance, and hence the transit time is independent of the setting. The attenuator is used in the vertical amplifier of a CRO, or as a potentiometer.

Title: Process of oxidation of cycloalkanes
Filed: 1961-12-19
Abstract: The catalytic oxidation of a cycloalkane having 5 or 6 carbon atoms in the alicyclic ring to form cycloalkanol and/or cycloalkanone in the liquid phase is effected by heating the cycloalkane, in liquid phase, with a molecular oxygen-containing gas in the presence of an oxidation catalyst, passing the vapour phase effluent from the oxidation reaction mixture into a condensation zone, cooling said vapour phase effluent so as to condense a predominant portion of the cycloalkane contained in said vapour phase effluent, removing said condensed cycloalkane from the hot end of said condensation zone and removing a predominant portion of other condensable and non-condensable components of said vapour phase effluent from the colder end of the zone. The thus condensed cycloalkane may be recycled to the reaction mixture.  The liquid effluent from the oxidation zone is passed to a suitable separating zone where it is treated to separate the cycloalkanol, cycloalkanone and partial oxidation products.  In a preferred embodiment of the process, the temperatures within said condensation zone are controlled so as to maintain the condensed cycloalkane at as high a temperature as possible while maintaining the condensed cycloalkane in the liquid phase.  This effects a stripping from the cycloalkane of other condensable materials.  The oxidation may be effected between 75 DEG and and 200 DEG  C., preferably in the range 140 DEG  to 175 DEG  C., and the pressure may be from 50 to 500 p.p.s.i., preferably 125-200 p.p.s.i.  The preferred cycloalkane are cyclohexane and cyclopentane. The oxygen-containing gas may be oxygen or air. The reaction time is controlled so that the conversion is from 1 to 30%, preferably from 5 to 15%.  The catalyst may be a hydrocarbon-soluble salt of cobalt, copper, cerium, vanadium, chromium or manganese. The temperature at the cold end of the condensation zone is generally 20 to 55 DEG  C. and at the hot end 25 DEG  to 65 DEG  C.
