Title: Improvements in or relating to machines for sorting goods
IPC: B07C3/00
Filed: 1939-04-11
Abstract: 527,420. Sorting goods; conveyers. LARHAM, D. P. April 11, 1939, No. 11038. [Class 117] [Also in Group XXX] Goods are sorted by placing the individual articles at a part 6, Fig. 1, on a conveyer 1 at definite time intervals indicated by the lighting of a lamp 5. Deflectors 11 are disposed along the conveyer at distances equal to the travel of the band during these intervals, and electrical means are provided for pre-selecting the operation of a deflector from the operator's station. Each deflector is actuated by a solenoid, and is retained in its operative position by a detent 17 which is released by the discharge of the article from the conveyer and returned to its inoperative position by a spring 13. The electrical circuits for a three stage sorting machine are shown in Fig. 2. The deflector-actuating solenoid 16 for the first stage is connected in series with a manually :actuated main switch 18 and a secondary swith 19. The main switch is spring biased so as to remain open, but when closed by hand is retained closed by a solenoid 20 in a parallel circuit including a switch 21 normally closed. The switch 19 is closed in synchromism with the arrival of an article at the first stage, and if the main switch has been closed, the solenoid 16 is energized and the corresponding deflector actuated. The switch 21 is then opened momentarily, thus opening switch 18, and when the selected article passes off the conveyer it releases the detent 17 and the deflector returns to its initial position. The connections for the solenoid 14 of the second stage comprise two similar parallel circuits including two main manually operated switches 22, 23, two secondary switches 24, 25 and two auxiliary switches 28, 29 controlling solenoids 26, 27. The auxiliary switches 24, 25 are closed at time intervals equal to the time of travel of the conveyer from one stage to the next, and if the appropriate main switch is closed, the deflector will be actuated when an article reaches this stage. In order to determine which of the two main switches requires to be closed, indicator lamps 52, 55 are in series with the main switches and with switches 53, 56 which are opened and closed in synchronism with the corresponding secondary switches 24, 25. The circuits and indicating means for the third stage solenoid 15 are similar in operation but triplicated, with intervals between the operation of the control switches equal to the time of travel between stages. The switches are actuated by rotary contacts driven through gears designed to give the necessary synchronization. The indicator lamps are mounted on the main manually actuated switches and function as the actuating means, and are arranged on a panel at the operator's station.

Title: Process and apparatus for the treatment of textile goods made from synthetic yarn material
IPC: D06B5/24
Filed: 1961-03-27
Abstract: <PICT:0914052/IV (b)/1> <PICT:0914052/IV (b)/2> A process for the treatment of textile goods made from synthetic yarn material comprising a plurality of strands includes conveying the goods in a freely suspended state through a shrinking bath p  without change of position in relation to the direction of the path, the goods remaining completely submerged, and then conveying the goods through at least one bath containing liquid capable of stopping the influence of the shrinking liquid.  The Figures show, diagrammatically, apparatus for carrying out the process.  1 is a shrinking vessel containing, for example, a phenol solution; 2 is a neutralising vessel containing, e.g. caustic soda solution and 3 is a rinsing vessel.  Goods, in this instance stockings 9, to be treated are placed in readiness on table 10 and attached to hooks 8 on one of several transverse bars 7 supported between a pair of endless chains 4, 5, one on each side of the apparatus.  The chains are rotated so that the goods are traversed through the vessel 1 and into vessel 2, and a further bar 7 is brought into the loading position.  After loading is completed on the second bar 7 the chains are again moved so that the second load takes up the position in vessel 2 and the first load is transferred to vessel 3.  After emerging from vessel 3 the articles are supported on rollers 12 in which position they are unloaded.  Before being led into vessel 1 the articles move across wings 14 on a roller 13, the peripheral speed being higher than the speed of the chains, so that the articles are fed into the vessel at a speed higher than that at which they are pulled forward at their front ends.  Fig. 5 shows the circulating system of the liquids in vessels 1, 2 and 3.  Working feed tank 21 containing shrinking liquid of higher concentration than that in vessel 1 supplies make-up liquid via pipe 20 through an air trap 19 to a transverse perforated pipe 18 to maintain a constant level in vessel 1.  Pipe 18 is connected to the suction side of a circulating pump 23 so that the make-up liquid does not flow directly into the bath in vessel 1 but is sucked into the circulating system together with liquid from the bath itself and flows out beneath the baffle 26 from transverse pipe 25.  An automatic dosage apparatus 29, controlled from a refractometer or other suitable instrument for determining the concentration of the solution in vessel 1, supplies strongly concentrated solution from feed tank 30 through an air trap 27 to the vessel 1, from time to time to compensate for the drifting of concentration of the bath in vessel 1.  38 and 39 are heaters for heating the solution entering feed tank 21 and vessel 1 respectively. Vessels 2 and 3 in this embodiment contain rinsing water and this is supplied through a conduit 40 to vessel 3 and flows from the latter to vessel 2. Vessels 1, 2 and 3 may be fitted with ultrasonic vibrators 17, 16 and 15 to obtain a more efficient and more uniform influence of the liquids on the textile material.

Title: Ball-point pens
IPC: B43K24/08
Filed: 1958-04-10
Abstract: 861,165. Reservoir pens. MEIER, G. April 10, 1958, No. 11431/58. Class 146(3). In a plunger-actuated, retractable ball-point pen the ball-point is locked in the projected position by the user's placing the writing end of the pen against a firm object, pressing the plunger against the action of a spring until the plunger is checked at a given distance from the writing end by the ball-point still within the writing end bearing against the firm object, and then drawing the pen away from the object, whereupon the ball-point will spring out and be locked in the projected position. As shown the pen comprises a two part -barrel 1, 2 in which a writing unit 3, biased rearwards by a spring 4, is slidable. The plunger is formed as a cap 7 slidably mounted on the rear end of the barrel and connected to a tube 5 in which the rear end of the writing unit 3 is slidable. The tube 5 contains, a spring 6 which urges the writing unit 3 and cap 7 apart. The writing unit is formed with a frusto-conical portion 5<SP>1</SP> behind which engage two leaf springs 9 to lock the writing unit in the projected position. To retract the writing unit the cap 7 is pressed forwards until a slidable sleeve 12 on the tube 5 is engaged by a ridge 13 formed on the tube and pushed forwards between the leaf springs 9. When pressure on the cap is released the sleeve 12 is carried forward by the springs. 9 until it abuts the rear end of the portion 5<SP>1</SP> and allows the springs to slide over the rear end of the portion. In a modification, Fig. 3, the rear end of the tube 5 is open and is spaced from the rear end of the cap 7. The writing unit 3 is extended rearwards beyond the rear end of the tube 5 and a spring 6<SP>1</SP> is partially enclosed in the rear end of the unit. Forward movement of the cap 7 in the projecting operation is thus limited by the abutment of the rear end of the tube with the rear end of the cap.

Filed: 1975-03-19
Abstract: 1458654 Electronic musical instruments WARWICK ELECTRONICS Inc 19 March 1975 [28 Aug 1974] 11497/75 Heading G5J An electronic instrument which includes circuitry for processing a tone signal to provide a selected voice has at least one variable control for selecting the voice and a switching device which when set disables the variable control and provides a preselected voice. The variable controls may be any of those found on a musical "synthesizer" and as described serve to control tremolo, vibrato and the characteristics of low pass and band pass filters. The instrument described has a keyboard which provides a voltage dependent on the key operated; a summing circuit which adds to the keyboard voltage a varying voltage from a low frequency tremolo oscillator, an octave shift voltage and a fine tuning voltage; a voltage controlled oscillator receiving the output of the summing circuit; a waveform selecting circuit which according to an applied voltage produces various shapes of rectangular and triangular waveforms from the oscillator output; a voltage controlled band pass filter whose centre frequency and bandwidth are variable according to applied voltages; a low pass filter whose cut off frequency is similarly variable; and a modulator which adjusts the envelope for attack and decay. The voltages which control the filters together with other voltages which control the envelope &c. are derived from a resistor matrix under the control of a plurality of voice switches. In addition the filter voltages can be offset from those selected by the resistor matrix by means of potentiometers (124, 136, 170) when the latter are connected between equal and opposite voltages. When the switching device (250) is set the potentiometers are not so connected and the filter voltages are determined solely by the resistor matrix. In addition when the switching device is set a variable depth control for the tremolo, vibrato circuits is disconnected and a preset potential divider selected by the voice switches is substituted.
