IPC: A23G3/26
Filed: 1936-06-10
Abstract: 476,261. Coating sweetmeats and pharmaceutical products. HOUNSELL (ENGINEERS), Ltd., J., HOUNSELL, W., and HOUNSELL, F. June 10, 1936, No. 16184. [Classes 28 (i) and 81 (i)] A machine for coating sweets and other edible or pharmaceutical products with sugar, flour, or like substances, comprises a rotatable drum 7 having a screw thread formed by an upstanding flange or wall 10 on the inside of the drum, and a mesh or small holes 12 in its wall near the delivery end through which the unused covering material can pass into a reverse screw passage or passages 15 formed on the outside of the drum, the material being thereby returned to the feed end of the drum where it is raised by longitudinal walls and falls through a grill or perforations 16 on to the sweets as they are admitted to the drum. The sweets are agitated during their passage through the drum by longitudinal ribs 11, integral with or attached to the drum, and having their steeper sides in the direction of rotation of the drum. The drum is provided at one end with a band 8 of friction material which rests upon belt-driven rollers 2, the other end of the drum resting upon freely mounted rollers 9. The delivery-shoot 14 and the feeding-shoot 20 are secured to the base 1 by lugs 21 engaging holes therein. The feed shoot 20 is formed with a circular plate 22 and a passage-way 24 down which fresh sugar passes from a feeding-device 25 provided with a hopper 26, closed by a lid 27, and a belt-driven shaft carrying paddles for agitating the sugar and moving it through a hole in a partition wall to an opening above the passageway 24. The feeding-device is so mounted that it may be swung to one side to permit the drum to be lifted from the rollers 2, 9. An inspection door 19 facilitates' cleaning of the passages 15. When the articles to be coated are wet and tend to moisten the sugar, the fresh sugar may be supplied on the feeding shoot to effect a preliminary coating before the sweets enter the drum.

Title: Improvements in or relating to electric current monitoring circuit arrangements
IPC: G06F11/00
Filed: 1961-05-05
Abstract: 946,420. Magnetic pulse generating circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. May 5, 1961 [May 10, 1960], No. 16402/61. Heading H3B. [Also in Division G1] The absence of direct current in one of a pair of current conductors 1, 2, Fig. 1, is indicated by the cessation of output pulses from a bi-stable pulse generator 3 alternately set and reset by cyclic pulses in time positions t 2  and t 1 . The direct currents in conductors 1 and 2 respectively apply equal set and reset biases and so permit the pulse generator to operate only if both are simultaneously present or absent. To enable a momentary cessation of direct current in a conductor to be indicated, the output from the pulse generator 3 (which is produced during the reset cycle in time positions t 1 ) is applied to a pulse gate 4. The output of this gate to a relay 8, by way of a transformer 5, rectifier 6 and smoothing condenser 7, is disabled if the cycles of pulses in the order t 1 , t 2 , t 3  applied to terminals 43-45 is interupted by absence of pulses in time positions t 1 . A pulse generator may be controlled by two pairs of conductors so that it fails when any one of the four direct currents ceases, and as shown in Fig. 2 two pulse generators 18, 19 are connected in cascade, the pulse output from generator 18 in time position t 1  providing reset pulses for generator 19. Seven current conductors 11-17 are used in the Fig. 2 embodiment, the conductor 14 being connected through both pulse generators so as to make up the necessary conductor pairs. Each pulse generator may comprise a magnetic storage core 21, Fig. 3, having opposed windings 29, 31 for the set and reset pulses respectively and opposed windings 28, 30 for the two current conductors forming a pair. Only when both currents in the pair are present or absent is the core alternately set and reset by pulses in windings 29 and 31 so as to induce output pulses in a winding 33. The output pulses are effective during the resetting time intervals t 1  to make a transistor 22 conductive, with the result that effective output pulses are obtained and the core switching is aided by current pulses in a feedback winding 32. A pulse gate is shown in more detail in Fig. 4 and comprises two pulse generators 41, 42. Resetting pulses in time positions t 1  and t 2  are applied to pulse generator 41, and the generator is set only if an output pulse is obtained from pulse generator 42 in time position t 3 . Pulse generator is set by the output from generator 41 and also by a pulse in time position t 1  and is reset in time position t 3 . If the t 1  position pulse is absent the pulse from generator 41 is insufficient to set generator 42 and pulse generation ceases. The gate is restarted by applying a setting pulse to generator 42 at terminal 46.

Title: Improved means of volume and tone control in audio-frequency amplifiers
IPC: H03G9/08
Filed: 1936-06-13
Abstract: 476,877. Valve amplifying circuits. SNEATH, O. B. June 13, 1936, No. 16573. [Class 40 (v)] In an audio-frequency amplifier for deaf sets and other purposes, volume or tone is controlled by variable negative feed-back from a resistance in the negative high tension lead of the output valve, the resistance being small compared with the output impedance. The variation may be obtained by tappings on the resistance, or a differential condenser across the resistance, or by variable resistances or condensers in the feed-back connection, and in some cases positive feed-back may also be obtained. In the arrangement shown in the Figure, control of volume is obtained by variation of tapping V on the resistance R1, condensers C1, C2 shunted by resistances R2, R3 being included in the feed-back path to the grid of valve A the input to which comprises a condenser microphone M. Resistances R2, R3 are high compared with the impedances of condensers C1, C2 at all material frequencies. Tone control is obtained by tapping T through resistance R4. Volume and high tones are at maxima when tappings V and T are at the upper end of resistance R<1> which may be 800 ohms. Condenser C2 and resistance R3 may be dispensed with, and resistances R2, R3 may be omitted if resistance R6 is provided in the grid circuit of valve A. Resistance R1 serves also as a bias resistance for the output valve and, if desired, for other valves also. Condenser C3 may be employed to give greater prominence to the high tones as T approaches the upper end of R1 and causes positive reaction at high frequencies. When automatic volume control is obtained by rectification of output current, Fig. 2 (not shown), the tapping T may be connected to the smoothing condensers of the automatic volume control bias. In a further modification, Fig. 3 (not shown), tone control is obtained from resistance R1 as before and volume control by a rheostat and fixed resistance in series connected across resistance R1. If the input load is resistive, the capacitative feed back path from V acts as a tone control and the other path from T operates for volume control and by connecting resistance in series with a capacitative load the range of tone control can be extended. When the load is not capacitative it may be made so by added capacity. Another modification, Fig. 4 (not shown) comprises a three-valve resistance capacity coupled circuit in which when the tapping V is adjacent the cathode, positive feed-back is present due to absence of decoupling or direct capacity feed-back from the anode of the second valve to the grid of the first valve. Negative feed-back is obtained by moving the tapping towards the other end of the resistance R1.

Title: Method for obtaining the optimum utilization of the natural grain-size of sands and gravels for concrete production
IPC: G05D11/13
Filed: 1969-03-31
Abstract: 1,241,878. Weighing electrically. (B) WOHNUNGSBAUKOMBINAT VEB. March 31, 1969, No. 16809/69. Heading G1N. In a concrete-making apparatus the mean value weighted in accordance with mass of a parameter representing the coarseness (F-value) of each of three different grades of aggregate is derived from a bridge circuit arranged so that for a mean F-value below a required value supplementary grade-improving material is added to achieve the required value. Potentiometers 1, 2, 3 are coupled to weighing devices so that each develops a voltage proportional to the mass of a different one of three grades of aggregate, the mass representing voltages being summed at a bridge arm 5. Each of the voltages is multiplied at 4 by a factor representative of the F-value of its respective aggregate, the resulting products being summed at a bridge arm 6. The ratio of the voltages across these arms thus represents the mean F-value weighted in accordance with mass of the three grades of aggregate and is compared with the ratio of the parts of the variable resistance 7, representing the required mean F-value. Any unbalance voltage acts through a Schmitt trigger circuit 8 to imitate addition of a grade improving supplementary material of which the weight added is monitored by a potentiometer 9. When the bridge is balanced the circuit 8 terminates the addition of supplementary material and actuates a change-over switch 10 so that the ratio arms of the bridge are comprised by the parts of a variable resistor 11, instead of that 7, of which the setting corresponds to a desired ratio between the mass of a binding agent or water represented by a voltage 12, replacing that 6, and that 5, representing the sum of the masses of the aggregates and supplementary material. The three grades of aggregate (sand, gravel) are graded by a sieving plant before weighing. A common weighing scales may be used.
