Filed: 1952-10-13
Abstract: 724,250. Printing-machines; feeding sheets. ADDRESSOGRAPH-MULTIGRAPH CORPORATION. Oct. 13, 1952, No. 25636/52. Classes 100 (1) and 100 (2). Also in Group XXIII] In a printing or duplicating machine the printing or offset cylinder carries a driving gear or sheet feed control cam movable as a unit therewith and adjustable relative thereto, a threaded clamping bolt, also movable therewith being adapted to clamp the driving gear or control cam in position and a clamp operating member is provided, mounted on the frame of the machine for movement into and out of a position in which it can engage the clamping bolt for release or tightening. The forme cylinder 15, Fig. 3, carries a driving gear 20a, meshing with gear 20b adjustably secured to the offset cylinder 16 by a clamping bolt 25 passing through an arcuate slot 24 so that the relative positions of cylinders 15, 16 may be varied. As shown in Fig. 4, the side member 11 of the machine frame is formed with an opening 32 in which fits a cylindrical plug 31 formed with an eccentric bore to guide a plunger 41 having a socket at the inner end to receive a hexagonal wrench key 42 adapted to enter a socket 27, Fig. 3, in the head of the bolt. A knob 45 at the outer end of the plunger 41 is used to press the key 42 into engagement with the bolt socket against the action of spring 49 and to turn the bolt to free the gear 20b. The other cylinder 15 may then be rotated to the desired position and the bolt 25 retightened. The stroke of the plunger is limited by a circlip 48 engaging the walls 44 of'a notch 43 in the plug 31. The plug is rotatable in the opening 32 to align the plunger with the bolt by slacking off screws 36 engaged in a clamping bar 35. The head of the bolt is conical to provide a camming surface 52 to displace the plunger should this be moved to the operative position while the machine is running. A similar camming surface may be provided on the end of the key 42. In the form of Fig. 7 the plunger 41 is urged into engagement with the bolt 25 by the spring 49 and normally retained in inoperative position by a spring-loaded latch 63 engaged in a circumferential slot 65. Should the machine be started when the plunger is in the inner position the cam surfaces 52, 54 coact to displace the plunger outwardly to the position where the latch engages the rearward sloping face 69 of the slot 65 thereby drawing the plunger clear of the bolt head. The key 42 may be engaged with the bolt head socket by releasing latch 63 and rotating the drum until the key snaps into the socket. Specifications 147,682, [Class 100 (i)], and 620,524 are referred to.

Title: Improved method for the extraction of casein from seeds
IPC: A23J1/14
Filed: 1946-08-28
Abstract: In the extraction of alcohol-insoluble casein from seeds with a solution containing alkali, water and less than 40 per cent of water-miscible organic solvent as in the parent Specification, the seeds are treated with at least part, preferably all of the organic solvent, before treating with the alkali.  The water may first be added to promote swelling, then the solvent, and finally the alkali, for example to a pH of 8.5-9.5.  After standing for about 1 hour, the solution is removed as by centrifuging.  A spinning solution may be formed directly or as a subsequent step. In examples, oil-free earth-nut meal is mixed with methylated spirits, acetone or methyl alcohol, and water, and after 1 hour 20 per cent caustic soda added. After standing for 2 hours, or overnight, the top liquor is removed, and protein precipitated with SO2.  Commercial meal is treated similarly using a larger amount of alkali.  Castor beans, freed from oil with acetone, are similarly mixed with ethyl alcohol and water, caustic soda added to a pH of 11.3, extracted for 48 hours, and the extract precipitated with sulphuric acid.

Title: Autocollimator for Measuring the Relative Position of Two Reflections.
IPC: G01B9/06
Filed: 1968-05-29
Abstract: 1,186,286. Autocollimators. ERNST LEITZ G.m.b.H. May 29, 1968 [June 8, 1967], No.25783/68. Heading G2J. An autocollimator for measuring the relative positions of two reflectors comprises an eye-piece 11, a test mirror 10, a reference mirror 9, an objective 6, and two sets of measuring marks 3, 4, which are focused to infinity through the objective and whereof one each is reflected by the test mirror and by the reference mirror and focused through the objective into the image plane 12 of the eye-piece. Due to the colouring of the image dividing prisms 7 (green) and 8 (red) the systems of measuring marks 3 and 4, of which system 3 may be numbered whereas the reference system 4 having a different lattice constant is unnumbered, produce images of complementary colours also. The pencil of rays is split by the image dividing prisms into two partial pencils of different colours, which when reflected separately, as described, produce both measuring systems in mutual superimposition through the objective 6 in the intermediate image plane 12 of the eye-piece 11. By additive mixing of the complementary colours, only one graduation will appear white. This white graduation then directly indicates the mutual angular difference between the two mirror inclinations. Alternatively in another embodiment Fig.2 (not shown) the two sets of measuring marks may take the form of two mutually nesting cross lattice systems (23) of complementary colours red and green, with different lattice constants, and the reference mirror may take the form of a dichroic ray divider (29). In another embodiment Fig.3  (not shown) the measuring marks (43), (44) may be polarized perpendicular to each other and one of the two sets may be measurably adjusted parallel to the optical axis. The reference mirror may be arranged on a lateral face of the polarizing divider cube (49a).

IPC: H04Q3/00
Filed: 1956-08-24
Abstract: 834,825. Automatic exchange systems. TELEPHONE MANUFACTURING CO. Ltd. Aug. 2, 1957 [Aug. 24, 1956], No. 25946/56. Class 40 (4). A selecting circuit comprises a number of bar-relay units with circuit interconnections. Numerical selector. When the circuit is taken into use contacts z1 close and impulses are received over lead IMP. Initially the first finger magnet FM-A1 of the first bar-relay unit is energized over back contact fp. The first impulse energizes the main magnet A of the first unit so that its armature closes the contacts A1, wa1, wal<1> associated with its first finger magnet. Finger magnet FM-B1 of the second unit therefore energizes. At the end of the first impulse relay FP operates to restore finger magnet FM-A1. The second impulse energizes the main magnet B of the second unit to close the contacts associated with its first finger magnet. At the end of this impulse main magnet A of the first unit restores. In this manner work contacts wa1, wa1<1> . . . we1, we1<1>... wa5, wa5<1>... we5, we5<1> are closed two by two. For the first 25 impulses relay WS is normal and the upper contacts wa1-we5 are effective. Thereafter WS is operated and the lower contacts wa11-we5<1> are effective. A further relay similar to WS can be incorporated to increase the capacity of the circuit to 75 or 100 conditions. Line-finder. Instead of driving the circuit by impulses it can operate to find a marked line as long as contacts wt are closed. Continuous scanning. The circuit may operate continuously by the inclusion of Fig. 3. At the 26th impulse the upper winding of W energizes and at the end of the impulse the shunt across the upper winding of X is removed so that X operates. At the 51st impulse the lower opposing winding of W energizes to restore W, and at the end of this impulse X restores. Varying sequence of search. A jumper field may be inserted in the line of jumpers JA-B, JB-C ... JE-A. Specification 703,931 is referred to.

Title: Improvements in or relating to quick make and quick break electrical switches
IPC: H01H23/16
Filed: 1924-11-04
Abstract: 246,913. Tucker. J. B. Nov. 4, 1924. Switches, quick-action. - The dolly 1 of a quick-make and quick-break tumbler switch is interconnected with the contact-carrier 8 so as to determine the extreme position of the latter. The quick action is obtained by a dead centre spring device comprising a compression spring 16 surrounding a stem 6, one end of which is slidable through a roller 5 mounted between the bifurcated extensions 4 of the dolly 1, and the other end 13 having lugs 14 slidable in slots 15 formed in the carrier 8. A pin 12 on one of the bifurcations 4 and offset from the roller 5 engages a triangular slot 11 in one side of the carrier 8. Upon moving the dolly 1, the pin 12 first engages one side of the slot so as to move the carrier about the pivot screws 10, whereafter when the dolly has moved to its fixed position, the pin 12 engages the other side of the slot to limit the throw of the carrier 8. The slot 11 may be formed in the dolly and the pin placed on the carrier, or the slot may be replaced by equivalent extensions on either member.

Title: Pneumatic percussion tool
IPC: B25D9/14
Filed: 1965-06-22
Abstract: 1,041,780. Percussion tools. JAEGER MACHINE CO. June 22,1965 [Aug.10, 1964], No. 26359/65. Heading B4C.  The piston 11 (not shown) of a pneumatic percussion tool is raised by compressed air supplied past a manually-operated throttle valve 38 into a chamber 50a above an annular valve member 55 and through bores 51 in the valve chest 50 and passages 30 (not shown) in the cylinder wall 15, to enter the cylinder through radial bores beneath the piston 11. When the piston 11 nears the upper end of the cylinder 15 the air pressure above it is such that the valve member 55 is raised to disconnect the bores 51 from the compressed air supply and to connect them to a chamber 53 vented to the atmosphere through a bore 54 (not shown). Compressed air is then supplied to the bores 58 in the valve member 55 to the space above the piston 11, whilst the space below the piston is exhausted to the atmosphere through ports in the cylinder wall. The piston 11 is thus driven downwardly and the valve member 55 returns to its lower position. Lubricating oil provided in a chamber 46 seeps through a porous plug 47 on to the valve parts when the compressed air supply is cut off.

Title: Improvements in or relating to work handling apparatus for conveying machines
IPC: B65G49/04
Filed: 1961-07-20
Abstract: 923,046. Step-by-step work conveyers for electroplating baths. UDYLITE RESEARCH CORPORATION. July 20, 1961 [July 20, 1960], No. 26430/61. Class 78 (1). Work containers 44 are supported by carriers 32 which are progressed stepby-step along, rail 36 and through electroplating bath 14. The carriers (with containers) are lifted over the walls of the container by means of pairs of movable walls 40 working in conjunction with pusher-bar 46. The movable rails 40 and pusher-bar 46 are carried by elevator 28 which is raised at intervals by chains 30 operated by piston and cylinder. The pusher-bar 46 operates by means of pivoted pawls 50, both in the lowered and raised positions. Special bath 14a.-This is intended either to give a delayed dip, i.e. a shorter dip, or a skip, i.e. to omit a dip. This is achieved in Figs. 2 and 3 by means of a carriage 68 which is caused to slide up an upright guide 62 by means of fluid cylinder 76, and by means of slidable rail 96 which is carried by carriage 68 and is caused to slide horizontally by cylinder 90 so as to be inserted into the gap between the two movable rails 40. Thus, elevator 28 carrying movable rails 40 and pusher-bar 46 moves up and down parallel to carriage 68 carrying slidable rail 96. The idea is to transfer a carrier 32 from a movable rail 40 to the slidable rail 96 so as to alter the period of dipping. Operation of special dip.-Elevator 28 is raised so that a carrier 32 on the left-hand movable rail 40 is carried up thereby. Then pusher-bar 46 operates to push carrier 32 from the said rail 40 on to the rail 96. The rail 96 carrying carrier 32 is then moved to the left by cylinder 90 into its leftmost position. Elevator 28 then operates to descend in the normal manner and subsequently rise into the elevated position shown. In this way the carrier on rail 96 is caused to miss its dip. Cylinder 90 then operates to move rail 96 to the right and pusher-bar 46 operates to move the carrier 32 on to the right-hand movable rail 40 ready for its next dip when elevator 28 next descends. In the case of a delayed dip, the carrier 32 on rail 96 is held in its elevated position by the operation of a timer and at a subsequent time cylinder 76 operates to lower carriage 68 and to immerse the work container 44 carried by the said carrier 32. Later, the carriage 68 and elevator 28 rise together to their elevated positions and transfer is then made by means of rail 96 to transfer the carrier 32 on to the right-hand rail 40. Carrier 32, Fig. 4.-The carrier 32 is provided with two adjustments, 116a and 116b. When the operator first puts the container on to carrier 32 he moves one or other of these adjustments which correspond respectively to the skip and the delayed dip operations. In this way he chooses between these operations and, in the initial movement upwards of elevator 28 as it raises carrier 32 on rail 40, the selected adjustment strikes a switch to adjust the electrical circuit to select the appropriate dip.

Title: Carrier communication system
IPC: H04J1/04
Filed: 1954-09-13
Abstract: 762,915. Multiplex systems. AUTOMATIC ELECTRIC LABORATORIES, Inc. Sept. 13, 1954 [Sept. 28, 1953], No. 26457/54. Class 40 (4). In a carrier current communication system for the transmission of signals in a plurality of contiguous channels of the same nominal width, one more carrier frequency than the number of channels is provided and a switching arrangement connects to the respective modulator and carrier frequency which is optionally either the one at the low frequency or the high frequency end of each channel filter. The audio " tail " in the system shown may be " four-wire" across terminals 3 and 5 or " two-wire " on terminals 5 and in the latter case a resistance hybrid 9 is brought into circuit. Low-pass filters 13 and 15 for the two directions and a V.F. or pilot filter 17 passing 3400-3550 cycles for signalling purposes are assembled in a plug in unit 19 which is identical for all channels. The modulator 21 and demodulator 41 of channel 1 may be fed by either an 8 or 12 Kc/s. carrier and the leads 23 are terminated on jacks 211M and 211D, Fig. 3, respectively. Carrier frequencies 8, 12-24 Kc/s. are also terminated on the jacks and the channel-carrier frequency interconnections are determined by the jumping across the pins of plugs 216A and 216B. Thus, channel send filter 27 selects the upper sideband on the 8 Kc/s. carrier when plug " A " is used and the lower sideband on the 12 Kc/s. carrier when plug " B " is used. Signalling is effected over lead 33 via a signalling oscillator 35 and a modulator 37 and the V.F. signal is combined with the channel signal through a hybrid transformer 25. Groups of four channels are modulated on a 96 Kc/s. carrier in pre-group units and an annulling unit 66 is provided to sharpen the filter cut-offs at the extremities. The combined pre-group unit outputs, after amplification, pass through an E-W station switch which inserts a modulator 99 in the " go " or " return " path in accordance with predetermined setting up arrangements. Pilot signals for automatic gain control and frequency correction are provided by oscillators 110, 112 and the signal passes to line via one of the directional filters 121, 115. Flat gain and slope control are effected in the system regulating unit and further regulation is effected by the V.F. signalling current in regulator 39. The V.F. signals which are selected by a filter 17 and amplified also energize a receive relay 55 to repeat the supervisory signals to the local switchboard over lead 57. All the frequencies required are derived from the outputs of crystal oscillators 165, 169, which are housed in an oven 163.
