Title: Volume and tone controls for an audio system
IPC: H03G5/02
Filed: 1974-09-25
Abstract: 1461187 Volume and tone controlling circuits MOTOROLA Inc 25 Sept 1974 [9 Oct 1973] 41767/74 Headings H4R and H4J In a volume and tone controlling circuit an input signal at 12 is applied via a transistor 20 to the common terminal of a differential amplifier 14 and the division between the two halves of the differential amplifier is controlled by potentiometer 30 to control the output signal level from one half of the differential amplifier, at 28. The input signal is also connected to a tone control circuit 68 having two transistors 76 and 84. At the minimum setting of tone control potentiometer 69, transistor 76 is conductive, providing attenuation of the input signal at all frequencies. Movement of the control slider 72 from the minimum position causes transistor 76 to be cut off but high frequencies are still attenuated by capacitor 78, so that a bass boost is effected. Further movement of the slider 72 causes transistor 84 to become conductive, making capacitor 86 effective to provide top cut. As described a second differential amplifier 50 is connected parallel opposed with the gain control differential amplifier 14 as far as d.c. is concerned so that the d.c. level of the output at the point 56 remains constant with movement of the control potentiometer 30 to prevent d.c. changes introducing noise. The volume and tone control potentiometers are common to an identical circuit arrangement, not shown, to provide control of both channels of a stereophonic amplifier. A balance control 46 differentially varies the collector loads of the gain control differential amplifier arrangement in the two channels.

Title: Process and electric-arc heated lance for the non-exothermic treatment of metal-containing material
Inventor: LAMB LEONARD DOUGLAS
IPC: C21C5/46
Filed: 1962-11-09
Abstract: In a process involving non-exothermic interaction between a gas and a metal-containing material, the gas stream is heated by passage through an arc established from a rod electrode disposed axially in the gas flow; the arc may pass to an annular electrode at the gas outlet or to the metal-containing material. One or more additional passages for the supply of gas may be provided coaxial with that containing the electrode.  Particular embodiments disclosed include the degassing of molten metals with a stream of hot inert gas, the desulphurization of molten ferrous metals with a stream of hot inert gas containing a reagent such as lime, calcium carbide or calcium cyanamide, and the carburization of molten metal with gas or a suspension of carbon.  The process may also be applied to the reduction of metallic compounds either by directing a stream of heated reducing gas thereon, or by introducing the compound into either the reducing gas or into a separate arc-gas where a multi-channel lance is used.  Easily ionizable substances such as argon, krypton, silicon tetrachloride, titanium tetrachloride chlorosilanes, or oxides or carbonates of alkali, alkaline earth or rare earth metals may be added to the arc-gas to stabilize the arc.

Filed: 1969-08-26
Abstract: 1,253,906. Valves. SAUNIER DUVAL. 26 Aug., 1969 [27 Aug., 1968], No. 42547/69. Heading F2V. [Also in Division G1] A fluid flow detector comprises a temperature variable resistor 3 of which a surface is in thermal communication when the fluid is flowing but is thermally insulated from it by a flexible heat-insulating diaphragm 11 when fluid does not flow. The resistor is heated by a constant electric current so that when the diaphragm is raised from the casting 5 due to pressure difference between inlet and outlet pipes 1, 2, fluid flows past the resistor and extracts heat therefrom whereby the resultant temperature change is detected to indicate the fluid is flowing. An aperture 15 in the diaphragm connects the outlet pipe with a chamber 16 in which a spring 12 is seated. The spring acts on an abutment 13 fast with the diaphragm to urge it to the casting 5 thereby blocking flow between inlet and outlet.

Title: Improvements in or relating to Hydro-Pneumatic Spring Elements
Inventor: KONING ARIE ADRIANUS DE
IPC: F16F9/50
Filed: 1968-09-11
Abstract: 1,195,809. Self-levelling suspension units. A. A. DE KONING, and K. K. K. DE KONING. 11 Sept., 1968 [22 Sept., 1967], No. 43289/68. Heading F2S. A self-levelling hydropneumatic damped spring is of the kind in which the two chambers into which a liquid-filled cylinder is divided by a piston communicate with two respective reservoir chambers containing liquid loaded by pressurized gas. The cylinder 1 and the reservoirs 6, 7 are defined by three concentric tubes of substantially the same axial extent, the liquid 8 in the inner reservoir 6 communicating with the cylinder space 5 surrounding the pistonrod 3 and the liquid 11 in the outer reservoir 7 communicating with the cylinder space 4 on the other side of the piston 2. The piston-rod is hollow and contains a pump which operates to maintain the piston at a predetermined mean position in the cylinder in the following manner. In the mean position, viz. the position shown, a port or ports 31 in the hollow pump plunger 21 is within the cylinder space 4 and a valve element 23 is just clear of an associated inlet aperture to the pump chamber 22. On inward movement of the piston 2 from this position the inlet valve closes and liquid from the pump chamber 22 will flow relatively freely into the cylinder space 4 by way of the port 31 until the latter is closed by the piston, whereafter a more restricted flow takes place by way of the valve 27-28 in the piston. Increasing pressure in the cylinder space 4 and its associated reservoir 7 will ultimately arrest and then return the piston to a condition in which the port 31 is open. If the piston-rod moves too far out of the cylinder the valve element 23 is lifted completely from the inlet to chamber 22 and, the port 31 also being unobstructed, the cylinder spaces 4 and 5 are in direct communication. This causes the pressures in these spaces to equalize by transfer of liquid from the former to the latter, thereby moving the piston back towards the mean position. The connection 19 between the cylinder space 4 and its associated reservoir 7 is constricted by a damping valve 19 ; a relief valve 40 is also provided, to open if the pressure in reservoir 7 becomes excessive, e.g. on overload. To ensure that the inlets controlled by valve element 23 and the outlet port 31 are opened gradually rather than suddenly, the pump plunger 21 is resiliently mounted at 20 and the port 31 may take the form of an axial slot.

Abstract: 1288110 Cleaning insides of containers; spray producers WOMA-APPARATEBAU WOLFGANG MAASBERG & CO GmbH 11 Sept 1970 [13 Sept 1969] 43472/70 Heading A4F [Also in Division B2] A process for cleaning the inside surfaces of containers by means of at least one jet of cleaning medium issuing from the same number of nozzles 3 rotatable about first and second axes at right angles (5, 6), Fig.2 (not shown), provides that the rotation of the or each nozzle about the first axis is due to the issuing of the cleaning medium from the or each nozzle and the rotary motion about the second axis is due to at least one pump (7), Fig. 2 (not shown) supplying fluid under pressure to a fluid motor 8, the rotary motion about the second axis depending on the output of the pump and the pump or pumps 7 being driven by the nozzle or nozzles. An apparatus for carrying out this process comprises a housing 1 rotatable about the second axis with respect to a connection flange for the cleaning medium 4 and the nozzles being rotatable about nozzle carriers 2. Gear wheels 14 rotate with the nozzles and drive pumps (7) via pinions 15. Fluid is thus pumped from reservoir 16 to motor 8 and via return pipe 19 back to the reservoir. The motor drives pinion 13 to rotate housing 1 carrying the motor &c. around crownwheel 12 fixed to the supply flange 4. Valves 20, 21 are set to give whatever rate of rotation of the housing is required. Slip in the drive, the absence of a fixed transmission ratio between nozzles and rate of rotation of the housing and random pressure fluctuations in the cleaning medium supply prevent the cleaning medium issuing from the nozzles from following a fixed track over the inside of the container.

Abstract: 1475110 Terminating insulated conductors BUNKER RAMO CORP 9 Oct 1974 [19 Oct 1973] 43788/74 Heading B3A Apparatus for terminating a plurality of insulated conductors 96 in respective insulationpiercing contacts of an electrical connector 90, Fig. 7, comprises connector support means for supporting the connector with its contact portions oriented to receive the conductors which are disposed adjacent and parallel to them, a carriage mounted for movement with respect to the connector support means to points corresponding to the contact spacing, an insertion tool mounted on the carriage for movement towards and away from the connector transverse to the path of the carriage and including at least one insertion blade for pressing the conductors into the insulation piercing contacts, and a programmer for effecting movement of the carriage to the points and movements of the insertion tools in accordance with a predetermined sequence. A cable 94 is first secured in a clamp 97 and the conductors 96 are dressed into comb slots which are aligned with channels 92 of the connector, the free ends of unused conductors being inserted in a spring 64. A ratchet mechanism, Fig. 5, is rotated to select a predetermined number of insertion operations. The ratchet is connected to a drum 142, Fig. 1, which is provided with axial slots 146 of varying lengths. Initiation of an operating cycle actuates an air cylinder 44 to extend its piston-rod 46 thereby moving a pin (144), Fig. 2 (not shown), along a slot 146 and at the same time aligning the insertion tool with a contact of the connector. The pin (144) moves the drum 142 forwardly until it abuts a bearing 128 and a flange on the drum actuates a valve (152), Fig. 8 (not shown). This valve actuates an air cylinder 98, Fig. 5, thereby pivoting insertion levers 86, 88 about shafts 38, 40, to drive a pair of conductors into their contacts by means of insertion heads 78, 80, which slide horizontally. The heads trim the conductors to length in co-operation with the combs. A pawl 134 on the lever 86 rotates the ratchet and at the end of the insertion stroke, the cylinder 98 is again actuated to retract the insertion heads and to rotate the ratchet further by a pawl 136 on the arm 88. Rotation of the ratchet winds a torsion spring (138), Fig. 6 (not shown), so that as the rod 46 is withdrawn and the pin (144) leaves the slot 146, the drum 142 is rotated to align another slot 146 with the pin. The insertion process is repeated automatically according to the pre-set programme determined by the number and length of the slots in the sleeve 142.

Abstract: 1388323 Money dispensers GLORY KOGYO KK 22 Sept 1972 [28 Sept 1971] 43908/72 Heading G4X  In a money dispenser there are detecting means 1, 2 for producing respective signals Pa, Pb on operation of a dispensing mechanism and the actual dispensation of a piece of money, either a banknote or a coin, through a dispensing outlet and means for evaluating the time lapse between said signals thereby to detect a fault in the dispenser. In the embodiment shown pulses Pa produced on each operative movement of the dispensing mechanism are applied as counting inputs to a counter 3 and pulses Pb are applied as reset inputs to the counter. If the counter reaches a predetermined level before being reset it operates via gate 5 to set flip-flop 6 to operate an alarm 7 and disable dispensing driving section 8. In a second embodiment (Fig. 2, not shown), the pulses (Pa) set a flip-flop (G1, G2) to charge a capacitor (C), which is discharged when the flip-flop is reset by a pulse (Pb). If the time-lapse between the pulses is excessive the voltage across capacitor (C) reaches a level sufficient to render transistor (T2) conductive and hence activate the alarm and disable the driving section. In a further similar embodiment, (Figs. 3, 4, not shown), the signal (Pa 1 ) is produced continuously while the dispensing mechanism is in operation and hence the flip-flop (G1, G2) is not required.
