Title: Machine for skinning meat and bacon
IPC: A22C17/12
Filed: 1959-08-31
Abstract: 925,641. Skinning bacon and meat. H. SCHILL, [trading as MAJA-MASCHINENFABRIK HERMANN SCHILL-KOMM.-GES.]. Aug. 31, 1959 [Sept. 3, 1958; Feb. 28, 1959], No. 29580/59. Class 28 (2). In a machine for removing meat skin or bacon rind by a blade 9 against which the meat or bacon is pulled by a toothed feed roll 1, the blade 9 is adjusted by moving its holder 10 to or away from the roll 1 by a lever 25 which on further movement beyond its adjustment path releases the blade and holder so that it can be removed bodily to facilitate machine cleaning. The lever 25 is slidingly keyed on a shaft 20 rotatably mounted in the machine side frames 22 and turns both the shaft 20 and, via a member 30, an eccentric 18 freely engaging thereover and which is journalled in side jaws 14 of the holder 10. To release the holder, the lever 25 is moved axially of the shaft 20 against a spring 27 to disengage from a peg 33 an arcuate slot 34 defining the lever adjustment path, and allow the further lever movement to a position in which the peg 33 engages a locating recess in the lever and the shaft 20 is presented to the openings of the jaws 14 to permit holder removal. During machine operation, yielding of the knife 9 under load is allowed by two spring plugs 36 engaging the holder 10, the eccentric 18 having a bore which is progressively relieved from its centre 41 to its ends to allow the inclusion in such yielding of slight sideways blade tilting. The feed roll 1 has circumferential grooves engaged by teeth of a pivoted stripping plate 8, one groove being deepened and engaged by a tapered tooth extension to ensure location when the plate is moved into engagement with the roll. Such movement is effected by pivoting of a feed table 12 into the almost horizontal operative position shown, when a link 55 turns an arm 56 fast on a shaft 46 eccentrically journalled in the machine frame, the consequent transverse movement of the shaft 46, on which two bearers 44 for the plate 8 are journalled, causing the plate to pivot about an adjustable stop 58. The shaft 46 has flats which align with slots 50 in the bearers 44 when the plate 8 is pivoted oppositely on lowering of the table 12, and allow plate removal for machine cleaning. A rotatable catch 60, 62 retains the table 12 in operative position. The blade 10 may be replaced by one with triangular teeth or by one which is reciprocated in its holder either by pin engagement with a sinuous groove in the feed roll periphery or by a driving motor separate from that driving the feed roll.

IPC: G05D23/24
Filed: 1959-08-31
Abstract: 878,053. Automatic temperature control systems. AMPHENOL-BORG ELECTRONICS CORPORATION. Aug. 31, 1959, No. 29662/59. Class 38 (4). [Also in Group XIII] In an automatic temperaturecontrol system for a frequency standard generator, temperaturesensitive components of an oscillator are contained within an inner oven enclosed within an outer oven; each oven has a separate heating element and control circuit, and temperature-sensitive components of the inner oven control circuit are contained within the outer oven. As shown, a crystal 11, associated capacitor 13 and inductance 14 of an oscillator 10 are contained in an inner oven 12 heated by an element 16. A temperature-sensitive resistor 43 is connected as one arm of a bridge having in the remaining arms resistors 44-47. The out-ofbalance voltage of the bridge control the amplitude of oscillation of a transistor oscillator 60, the frequency of which is determined by a resonant circuit 59. A transistor amplifier 66 is coupled to the resonant circuit by a winding 65. A transformer having a primary 67 in the collector circuit of the transistor 66 has a secondary 68 supplying the temperature-sensitive bridge and a secondary 75 connected to a transistor amplifier 76. The voltage across a secondary 78 of a transformer in the output from the transistor oscillator 76 is rectified by a full-wave rectifier 80 and applied as a bias to the base of a transistor 83 controlling the current to the heating element 16. The element 16 is energized so as to tend to maintain the inner oven temperature constant at the turning-point of the crystal 11 by the output voltage of the oscillator 60 falling to zero as the temperature increases. The temperature of the outer oven is controlled by a temperaturesensitive resistor 89, through a modification of the system for the inner oven, varying the supply to a heating element 20. The output of a transistor oscillator 105 is fed to a transistor amplifier 108, the output of which is rectified to apply a bias to the base of a transistor 118 controlling the current to a relay coil 119. When a temperature-sensitive bridge comprising resistors 85-89, approaches balance the current to the relay coil 119 is reduced and a relay contact 122 is opened to disconnect the element 20 from a battery 121. The components comprising the inner oven controller 42 are contained in the space between the inner and outer oven.

Title: Method and apparatus for the transmission of binary information  by means of two distinct frequencies
IPC: H04L5/26
Filed: 1971-06-24
Abstract: 1326831 Digital transmission; FSK modulators CHARBONNAGES DE FRANCE 24 June 1971 [9 July 1970] 29749/71 Heading H4P A fsk transmitter has a single oscillator switchable to two frequencies, each associated with separate information items from sources A, B, the output from which is passed to line through a filter which is switched synchronously to a corresponding frequency range; the oscillator is also blocked by a circuit operative, when incoming information is switched to the opposite state e.g. "1". The oscillator comprises a transistor T1 associated with a winding Trp 1 and capacitor C1 normally tuned to a higher frequency, and switched to a lower frequency by capacitors C2, C3 by a transistor T2. The output filter comprises a transformer Tr2 normally tuned to the lower frequency is switched to the higher frequency by capacitor C5 when a transistor T4 is conductive. Because coupling and amplifying transistor T5 causes a rectified parasitic current to pass through winding Trp 2, this is opposed by correcting winding Tra 2 on the same core. When the incoming signal or signals change state to a "1" this is detected by coincidence circuits CA, CB which render a transistor T3 conductive which blocks the oscillator. The arrangement may also be utilized to indicate the positions of mechanical elements by contact or magnetic sensors or other switching device, or indicate whether an electric motor is running or not, modifications to the arrangements being described with reference to Figs. 3 and 4 (not shown). Generator (G) Fig. 1 (not shown), provides a repetitive series of signals (s1, s2) which switch the oscillator and filter continuously between the two frequency values as long as the information sources A, B are emitting "O" signals.

Abstract: 1,109,506. Transistor pulse circuits. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. 23 July, 1965 [28 July, 1964], No. 30029/64. Heading H3T. A pulse is transmitted by a transmission or delay line from the output of a first transistor to the input of a second, the latter, together with associated resistors, providing a correct termination and a power supply for the first transistor. When transistor T1 is conducting the voltage at the lower end of R4 is such that T2 is cut off. When an input pulse cuts off T1, T2 conducts and its base emitter impedance together with that of the associated resistors correctly terminates the line. R3 and R4 in parallel are equal to twice the line impedance so that at the end of the pulse, when T2 cuts off, the mismatch is not large. The line may be coaxial, a twisted pair or a lumped delay line.

Title: Data Signalling Systems.
IPC: G11B20/14
Filed: 1968-06-24
Abstract: 1,165,658. Data storage. INTERNATIONAL BUSINESS MACHINES CORP. 24 June, 1968 [17 July, 1967], No. 30073/68. Heading G4C. In a data signalling system, a bit of one kind (1) is represented by a transition near the centre of a bit " cell " and a bit of the opposite kind (0) by a transition near the start of a bit " cell " except when it follows a bit of the one kind when it is represented by no transition. A " transmitter " converts data into this form for transmission or recording on to a magnetic tape, disc or drum store. A " receiver " converts data from this form after reception or reading from the store. Transmitter (recording), Fig. 1.-Parallel input data 12 is serialized in register 10, each bit being gated at 16, 18 by an " EVEN " clock pulse to set or reset a trigger 34 according as the bit is 0 or 1. The " EVEN " clock pulses are produced alternately with " ODD " clock pulses by an oscillator-driven trigger 22, one of each type of pulse per bit period. A write circuit 38 produces a transition for each pulse it receives from an OR 36 which receives a pulse from AND 16 at " EVEN " clock pulse time for each 1 bit and a pulse from an AND 42 at " ODD " clock pulse time for each 0 bit not immediately preceded by a 1. Receiver (reading), Fig. 3.-A processor 60 including an amplifier, filter, differentiator, limiter and shaper produces a pulse for each positive and negative peak of the received (read) waveform, the pulses being delayed and sharpened at 98 prior to gating, at 94, of the pulses representing 1 bits, into a serial-toparallel converter 106. A ramp generator 68 produces two ramps per bit period and is kept in sync. with the data from processor 60 by an error detector 66 which adjusts the ramp frequency. A threshold detector 72 responds to each positive and negative peak (Œ 3 volts) of the ramp to switch a trigger 88, and also control ramp flyback via a delay 78. A threshold detector 74 supplies a pulse to an OR 92 as long as the ramp is above +2 volts or below -2 volts. The OR 92 also receives the set output of trigger 88 thus producing a pulse of duration about 60% of the bit period to gate any 1 bit pulse at AND 94 to converter 106. Any 0 bit pulse (i.e. representing a 0 not immediately following a 1) is gated through an AND 86 as shown. The trigger 88 may be phase-locked to a reference.

Abstract: 483,927. Tyre formers. BRIDGE & CO., Ltd., D. (National Rubber Machinery Co.) Nov. 5, 1936, No. 30082. [Class 87 (ii)] In a rotatable tyre-building drum having key sections and intermediate sections all capable of being collapsed radially, the key sections are also adapted to be received on a mobile structure and removed laterally out of the plane of the drum after collapse, and rotary power means is provided to rotate the drum and effect collapse and expansion of the key and intermediate sections. The drum sections comprise a central portion 20 and adjustable flanges 21 which are provided when expanded with trimming rings 25 retained in position by a latch 28. The drum is mounted on a rotatable spindle 11 which carries a hub structure 32 having three brackets 35 in which tubular bushings 36 can slide radially. The intermediate sections 19 of the drum are carried by sleeves 37 which slide in the bushings 36, outward movement being limited by a headed rod 39. The inward movement of the tubes 36, 37 is limited by the reduced end 11b of the spindle 11. The sections 19 are collapsed and expanded by a sleeve 12 which surrounds the spindle 11 and can rotate therewith or relatively thereto. The sleeve 12 carries a ring gear 42 meshing with pinions 43 on shafts mounted in the brackets 35. The shafts also carry pinions 44, Fig. 3, which operate racks 47 to collapse the sections 19. The key sections 18 are carried as a separate unit on a tubular screw member 51 adapted to fit over the end 11b of the spindle The member 51 carries at its forward end a bushing 55 having three pairs of brackets 60 in which slide radial rods 65 carrying the key sections 18. The bushing 55 is positioned by a lug 61 engaging a groove 62 in the bracket 35. The sections 18 are expanded and collapsed by bell-crank levers 70 connected at their inner ends to a nut 76 threaded on the member 51. The means for moving the key sections laterally out of the drum comprises a carriage 83, Fig. 1, running on a rail 82 and supporting a hub 87 in which a spindle 89 rotates. This spindle has a hexagonal portion 89b, Fig. 5, adapted to engage a corresponding part 53 of the member 51, a shear pin 95 preventing rotation of the spindle 89 in the hub 87. When not engaged by the spindle 89, the end of the member 51 is protected by a cap attached to the nut 76 by a bayonet joint. In the collapsing operation, the cap is removed and the spindle 89 engaged in the member 51. The drum is then rotated, thus causing the nut 76 to travel along the fixed member 51 and collapse the sections 18. Rotation of the drum is then stopped and the carriage 83 is moved away carrying the key sections with it. The spindle 11 is again rotated while a brake 15 is applied to the sleeve 12 to cause collapse of the intermediate sections 19. Expansion of the drum is performed in the reverse manner.

[Also in Group XXX] A load-indicator or alarm for a lifting- device, in which a single ring-shaped element 3 acts on at least one switch 13 when a definite load condition is exceeded, is characterized in that the crosssection of the ring 3 has an axial width exceeding its radial thickness. The ring 3 is attached at 1, 2 to the apparatus, the tension in which is to be indicated. Four micro-switches 13 are mounted on a spindle 11 and can be adjusted in position by a screw 18. The operating levers 14, urged clockwise (as shown) by a spring 15, are pivoted on a spindle 12, both spindles 11, 12 being mounted on a plate 10 connected to the top part of the ring 3. A roller 19 on each lever 14 rests against a cam-plate 6 attached to the lower part of the ring. Thus deformation of the ring 3 causes the levers 14 to turn anti-clockwise and break their contact with the switches 13. The micro-switches are individually adjusted so that each one operates in turn to give warnings as the load increases. The final switch is also arranged to operate a cut-out device, stopping operation of the machine. It is stated that the shape of the ring is such that it responds only to forces applied parallel to the planes containing its end faces.
