Title: Improvements in and relating to Control Arrangements for Soil Working Implements
Inventor: SCHNEIDER WALTER
IPC: A01B63/111
Filed: 1966-08-20
Abstract: 1,154,468. Tractor power lift mechan- TRAKTORENWERK SCHÍNEBECK VEB. 20 Aug., 1966, No. 37420/66. Heading A1P. A position control follow-up cam 23 associated with a position control valve 15 operates in combination with pressure fluctuations in the ram 4 to move a main control valve 1 whereby the depth of penetration of an attached implement is controlled. A decrease in draft of the implement initiates an increase of pressure in ram 4 which is applied via line 2 to move the valve 1 to the lower position against the pressure applied via line 18 from the accumulator 20. Lowering of the implement allows cam 23 to move the valve 15 via lever 7 into the raise position. Fluid pressure is then applied via lines 8, 14 and 18 to the valve 1 to move it into the raise position whereby the implement is raised until the valve 15 is returned by cam 23 to the neutral position and the pressures in lines 2 and 18 are equalized to return valve 1 to the neutral position. An increase in draft acts in a similar manner first to raise the implement and then to lower it. The response of the system is damped by an adjustable throttle 21 mechanically connected to the manual lever 6.

Title: Terry Loom with Fell Shifting Means
IPC: D03D27/08
Filed: 1967-08-15
Abstract: 1,168,308. Terry looms. CANNON MILLS CO. 15 Aug., 1967 [20 March, 1967], No. 37441/67. Heading DIE. In a terry loom additional forward and rearward rotations are imparted to the take up roll 51 which in conjunction with similarly timed movements of a ground warp shifting roll 14 move the fell to produce three pick terry cloth. Normal take up is from a rocker shaft 64, through a pawl and ratchet drive 81 to a sun wheel 102 and planet wheels 103 to drive the shaft 51a. The second driving connection to produce the additional rotation in the take up roll 51 is from a terry cam 122, terry rocker shaft 116, link 114, bell crank 112 and link 110 to a second sun wheel 101. The ground warp shifting roll 14 is carried arms 130, 130a on each side of the loom (only one is shown) and is driven by a crank 115 through a link 131 from the terry rocker shaft 116 and moves in cooperation with the take up roll to move the fell. When the terry cams low surface engages its follower the link 110 moves upwardly and produces an increased take up on take up roll 51 and this occurs with a downward movement of the shifting roll 14 to allow the fell to move forwards. Thereafter, following a number of loose picks a high part of terry cam 122 produces a corresponding rearward movement, normal take up being separately operated at each pick. A pattern control swinging latch arm 140 can be operated to maintain the terry cam follower 121 out of contact with the terry cam 122 during non terry weaving operation of the loom and a pawl drive to the terry let off motion is disengaged so that the terry warps are maintained under normal tension corresponding to the tension of the ground warps during this period.

Filed: 1962-10-05
Abstract: 1,025,661. Automatic control of light; photographic camera with exposure control means. EASTMAN KODAK CO. Oct. 5, 1962 [Oct. 5,1961], No. 37686/62. Headings G2A and G3R. (Also in Division G1] The amount of light reaching a photo-cell unit is controlled by an obturator operated by a coil 10 (Fig. 5, not shown) rotatable in a magnetic field without mechanical restraint and connected across a bridge circuit of which at least one arm comprises the photo-cell unit. The bridge is energized by a D.C. source which thus drives the controlling means until the light on the photo-cell unit reaches a predetermined value, when the bridge is balanced. The photo-cell unit may comprise one or two photo conductive elements (Figs. 2, 3 not shown) or one photo-voltaic cell of selenium, its voltage balancing that of a battery in an opposite arm of the bridge (Fig. 4, not shown). The light control means may be a diaphragm 9 with a variable width gap 9a or a variable density filter. When applied to a cinecamera (Fig. 1, not shown) the diaphragm 9 is placed in front of the rear component of a Zoom lens and a revolving shutter 4 behind the component alternately admits light to a film gate 5 and reflects it to the photocell unit 7, through a lightconducting rod 6. For a still camera separate diaphragms and objectives are provided for the photocell unit and the film. Adjustment for film speed and the like may be made by adjustment of resistors in the bridge or by attenuating the light reaching the photo-cell. The moving coil may also carry  a pointer and this may be sensed by a conventional pointer sensing mechanism to regulate the exposure. The invention may also be used simply to measure light as in a hand held meter. The power source may be a battery, with a switch coupled to the camera release, or a selenium cell placed to receive maximum light.

Title: Improvements in or relating to electrical signalling systems
Inventor: DAVEY ROY CECIL
IPC: H04B17/40
Filed: 1959-11-06
Abstract: 914,788. Feeding and supervising unattended repeaters. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. Oct. 27, 1960 [Nov. 6, 1959], No. 37765/59. Class 40 (4). In a carrier telecommunication system in. cluding a plurality of repeaters fed in series by a constant direct current source over the signalling circuit, a relay in each repeater when first operated by the D.C. disconnects a resistor from across the D.C. feed circuit, the values of the resistors progressively increasing for each repeater so that the relays operate in sequence. The values of the resistors RA1, RB1, &c. are chosen so that on applying .current to the central conductors of coaxial cables +, - leading to the repeaters AP1, AP2, &c. from a terminal station BN, initially only sufficient current is available for operating relay A. This open circuits resistor RA1 so that more current is available for relay B which then pulls up and so on. This occurs as far as the turn-round point indicated by choke CH1, further repeaters being put into operation using a similar technique from terminal station CH. Two communication systems α, # each employing separate cables for the GO and RETURN paths, have a common supply system. Each path includes gain regulators, e.g. GN controlled by a pilot signal and in the event of a regulator being required to adjust the gain by more than a predetermined amount, i.e. due to some failure in one of the transistorized repeaters preceding it in the GO path, a relay operates which at contacts α1 (corresponding to GO path from BN) or α2 (from CH) puts a resistor of characteristic value across supervisory leads BC (lead A being connected to lead B through resistor R, Fig. 4). A milliameter (not shown) is connected to lead B and an alarm relay (not shown) is connected to lead C, the meter being calibrated so that the section in which the faulty repeater lies can be read off directly. If a line fault should occur, e.g. a break between repeaters AP2, AP3 in the GO path, relays A-F will drop out and then since the original conditions exist, i.e. resistors RA1 &c. in circuit, relays A, B will re-energize but now relay C cannot operate and hence at contacts C2, a characteristic resistor RC2 is connected across supervisory leads B and D. An alarm is given as indicated above. If the repeaters are contained in pressurized containers then a loss of pressure is indicated by the closing of contacts GAS1, GAS2, &c., which introduce further characteristic resistors across supervisory leads B and D.

Title: Method of regulating and stabilising the temperature of a fluid flowing from the outlet of a conditioning duct
IPC: C03B5/24
Filed: 1973-08-09
Abstract: 1420852 Automatic control of temperature of molten glass SOC GENERALE POUR L'EMBALLAGE 9 Aug 1973 [10 Aug 1972] 37790/73 Heading ClM [Also in Division G3] In an arrangement for controlling the temperature of molten glass being delivered from a smelting furnace (not shown) through a duct having a plurality of sections 1, 2, 3 (Fig. 2), each section has automatic control means arranged to adjust the glass temperature therein to a predetermined desired "instruction" temperature for that section, and in addition, the instruction temperature for a respective section is automatically adjusted as a function of the difference between the glass fluid temperature measured at two points adjacent the flow outlet from the section immediately downstream of said respective section. Considering section 1, a regulator 18 compares the glass surface temperature sensed by a theremocouple 16 with an instruction temp. 16a. The instruction temp. 16a is corrected by a signal from a regulator 25 and which is a function of the difference between the surface and bottom temperatures in the same transverse section of the duct section 2 downstream of 1 and sensed by thermocouples 26, 24 respectively. A resultant control signal from the regulator 18 controls via a valve 12 burners 10 for heating the glass in section 1. The burners for section 2 are likewise controlled. Burnt gas and vent air exits through ducts (14) Fig. 1 (not shown). Vent air flowing via nozzles 11, 21, is controlled by manually operated valves 13, 23. In a modified arrangement Fig. 3, the vent valves 13, 23 are servo-controlled by respective regulators 19, 29 in response to the differences between bottom temperatures sensed by thermocouples 17, 21 and respective instruction temperatures 17a, 26a. The regulators 25, 35 which produce the correction signals for the instruction values 16a, 26a are supplied with the temp. signals from thermocouples 24, 34 and in addition with instruction values 24a, 34a respectively. The latter are based on the assumed temp. difference between temps. sensed by 24 and 26 or between 34 and 36 of sections 2, 3 respectively. The exit end of section 3 has a separate row of burners 40 controlled by a regulator 48 to maintain the temp. sensed by a thermocouple 46 at an instruction value 46a.
