Title: Improvements relating to speed control means for the rollers of textile processing machines
IPC: F26B13/14
Filed: 1949-09-28
Abstract: 673,000. Fluid-pressure servomotor-control systems. SMITH & CO. (WHITWORTH), Ltd., F., and LEACH F. Dec. 27, 1950 [Sept. 28, 1949], No. 24869/49. Class 135. A textile processing machine in which a web of cloth travels under and over rollers and between two pairs of nip rollers is provided with a feeler roller located between the pairs of nip rollers, the feeler roller being displaced if shrinkage or extension of the cloth occurs, and such displacement actuates the control valves of a pneumatic or hydraulic system acting on a variable-speed pulley in the drive to the forwarding rollers. As shown, movement of the feeler roller causes a rod 9, acting through a lever 10, to rotate a face-plate cam 11 which acts on one or the other of two valves venting, respectively, the chambers on the two sides of a servo-piston 17. The two sides of the piston are continuously supplied with pressure-fluid from a line 15 past restrictions 16. The ensuing movement of the servo-piston, acting through a cam 19 carried by the stem of the piston and a bell-crank follower 21, adjusts one of the flanges 24 of an expanding pulley which is coupled to the driving rollers of the machine through a reduction gear 27. Movement of the servo-piston is communicated through an arm 28 and link 29 to the plate 30 carrying the vent valves to reset the latter to neutral position with reference to the actuating cam plate 11.

Abstract: 961, 634. Automatic speed control. AMPEX CORPORATION. June 29, 1962 [July 10, 1961], No. 25143/62. Heading G3R. [Also in Division H3] In wideband magnetic tape apparatus for frequency modulated signals a high frequency pilot signal is recorded with the information and during playback this is converted to a signal at a lower frequency suitable as an error signal for a known control system for the apparatus, e.g. that described in Specification 915,254. The reproduced pilot signal, e.g. 500 K.c.p.s. square wave, containing timing errors is converted to sharp positive peaks in a blocking oscillator 12 (see Division H3). These form one input to an AND gate 30, the other input comprising pulses derived from a one shot multivibrator 38. The pulses are long enough to trigger the AND gate for a few of the positive peaks and are repeated at the low frequency of a standard oscillator 32, e.g. 15, 625 c.p.s. The output of the AND gate triggers a second one shot multivibrator 68 resulting in a series of pulses of constant length (determined by the multivibrator 68) with a repetition frequency of that of the standard oscillator 32 and containing the timing errors present in the reproduced pilot signal.

Title: Dried blood pigment preparation for comminuted meat products and method of preparing same
Inventor: ZIEGLER JOHN ALEXANDER
IPC: A23J3/12
Filed: 1961-07-12
Abstract: A dried animal blood pigment suitable for use in comminuted meat products is prepared by converting all the methaemoglobin and oxyhaemoglobin in animal blood to haemoglobin, then converting the haemoglobin so obtained to nitrosohaemoglobin, adjusting the pH of the resultant product to a value in the range of between 7 and 9, and converting the mixture to a dry powder in such a manner that the colour characteristics of the red blood cells are maintained.  Thus, anticoagulant-containing animal blood or defibrinated blood, from which plasma has been separated, or red blood cells are treated with an aqueous solution of an edible reducing agent capable of reacting so as to convert all methaemoglobin and oxyhaemoglobin to haemoglobin, an aqueous solution of an alkali metal nitrite is then added in a quantity sufficient only to convert the haemoglobin to nitrosohaemoglobin, sufficient edible buffer solution is added to bring the pH value into the range 7.3-8.0, and the liquid mixture is either spray-dried at a temperature below 250 DEG F. or freeze-dried to a dry powder of less than 2% moisture content.  Preferably the reducing agent is added in excess in order to inhibit oxidation of the nitrosohaemoglobin subsequently formed.  The dried powder may be sterilized by treatment with ethylene oxide or propylene oxide; the sterilizing gas may be combined with an inert non-inflammable carrier such as carbon dioxide, nitrogen or helium.  The dried powder may be stored for months in polyethylene lined containers. Anticoagulants: water soluble alkali metal salts of phosphoric or polyphosphoric acids such as sodium ortho-, hexameta-, pyro- or tripolyphosphates, sodium citrate or sodium tartrate.  Reducing Agents: ascorbic acid, erythorbic acid, or any alkali metal salt, e.g. sodium salt, thereof. Buffer Materials: sodium hydroxide, carbonate or phospate, but preferably sodium bicarbonate. Examples giving the temperatures and times of the reaction steps are disclosed.  Sausage meat formulations containing 1/2 oz.-3oz. of the dried pigment per 100 lb. sausage meat also are given; these formulations exhibited an enhanced resistance to fading under fluorescent light.

The tool is particularly useful for the deformation of wall anchors but can also be adapted for use as pincers or nut-crackers. Both handles may be pivoted to the head at pivot pins 4 which pass through opposed side plates 3a of the head. A slot 3c is provided in each side plate to receive an axial projection 6a of the cylindrical follower 6. A slider 5 is mounted on the cross-member (3b), Fig. 3 (not shown), of the head and includes holes 5a for alignment with a hole (3d) in the crossmember. The aligned holes receive an operating member or rod 7 which is rotatably received in a bore of the follower. The rod has a knurled lower portion7a and a threaded upper portion 7b. In use, an appropriately sized rod 7 and follower 6 are selected for a wall anchor 10, Fig. 4, and the rod is passed axially into the anchor. The rod is threadably engaged in the internally threaded portion 14 of the anchor and the latter is inserted into a hole 11 formed in a support 12. A flange 13 may prevent the anchor from passing completely through the hole. The slider 5 abuts the flange and the handles are pushed together so that cam portions 2c act on the follower and force it away from the slider. This movement withdraws the rod and applies axial compression on the anchor causing the legs 15 to deform until they abut the support 12 surface. The knob 7a is then twisted to unthread the rod from the anchor.

Abstract: 1,198,572. Refrigerating. ROBERT BOSCH HAUSGERAETE G.m.b.H. 30 May, 1968 [1 June, 1967], No. 25862/68. Heading F4H. A refrigerating machine having an injector compressor operated by vaporized refrigerant includes a change-over device for selectively supplying refrigerant to a heat exchanger as a cooling or a heating medium. As shown, liquid refrigerant is vaporized in a coil 3 of a vapour generator 1 and supplied to the injector 5 which discharges to a port 22 of a slide valve 20. In the valve position shown, the compressed refrigerant passes through a port 23 to a condenser 6 from which liquid refrigerant passes via a check valve 8 to a receiver 9, and thence to heat-exchangers 13, 13<SP>1</SP> via expansion valves 11, 11<SP>1</SP>. Refrigerant vapour from the heatexchangers returns to the suction inlet of the injector via lines 14, 14<SP>1</SP>, ports 25, 26, 24 and line 15 while part of the liquid from the receiver 9 is pumped to coil 3 through line 17. Air to be conditioned flows serially through the heatexchangers. As the slide 21 of valve 20 is moved to the right it successively occupies positions in which:- (i) port 26 is blocked and heat-exchanger 13<SP>1</SP> rendered inoperative; (ii) port 26 is communicated with port 22 so that exchanger 131 receives hot refrigerant from the injector and reheats air which has been cooled and dehumidified by exchanger 13; (iii) ports 24 and 25 are blocked so that exchanger 13 is inoperative and air is heated by exchanger 13<SP>1</SP>, and (iv) port 23 is closed and port 22 communicates with both ports 25 and 26 to supply hot refrigerant to both exchangers. Refrigerant condensed in the exchangers while they are used for heating passes to the receiver 9 through lines 18, 181 which include checkvalves 19, 191. In a different embodiment (Fiig. 1, not shown) having a single heat exchanger, a change-over valve is provided at the outlet of the coil 3 for supplying vapour either to the inlet of the injector or directly to the heat-exchanger. The machine may be used in a motor vehicle in which case the vapour generator 1 is heated by the engine exhaust.

Title: Electronic timepiece
IPC: G04G5/00
Filed: 1978-05-31
Abstract: The time-resetting device comprises means of control of the motor (29), means of inverting the polarity of the drive pulses (25) and a circuit (39) for detecting the position of the rotor of the stepper motor given the position of the polarity-inverting means (25). This detector circuit operates only during the first period after the cessation of the state for resetting the divider to zero, and it then delivers a detection signal which, depending on the situation detected, does or does not comprise a detection pulse. The latter is applied to an inverter control circuit (19) which acts on the polarity-inverting means (25) so that they effect a further permutation in the event that the detection means register a position of the rotor such that, without prior inversion, the next advance pulse would not be able to make the latter advance. <IMAGE>
